string(138) " on the ground that in India, where most of the population and especially women \(wife\) do not have actual possession over any property\." DARSHAN SINGH PATIALVI ââ¬â ADVOCATE GENERAL | Restitution Of Conjugal Rights: Criticism Revisited| Introduction:- Section 1[1] of the Hindu Marriage Act, 1955 embodies the concept ofà Restitution of Conjugal Rightsà under which after solemnization of marriage if one of the spouses abandons the other, the aggrieved party has a legal right to file a petition in the matrimonial court for restitution of conjugal rights. This right can be granted to any of the spouse. This section is identical to section 22 of the Special Marriage Act, 1954. We will write a custom essay sample on Family Law- Hindu Law or any similar topic only for you Order Now [2] The provision is in slightly different wordings in the Parsi Marriage and Divorce Act, 1936, but it has been interpreted in such a manner that it has been given the same meaning as under the Hindu Marriage Act, 1955 and the Special Marriage Act, 1954. However, the provision is different under the section 32 Indian Divorce Act, 1869 but efforts are being made to give it such an interpretation so as to bring it in consonance with the other laws. The provision under Muslim law is almost the same as under the modern Hindu law, though under Muslim law and under the Parsi Marriage and Divorce Act, 1936 a suit in a civil court has to be filed and not a petition as under other laws. [3]The constitutional validity of the provision has time and again been questioned and challenged. The earliest being in 1983 before the Andhra Pradesh High Court[4] where the Honââ¬â¢ble High Court held that the impugned section was unconstitutional. The Delhi High Court inà Harvinder Kaur v Harminder Singh,[5] though had non-conforming views. Ultimately Supreme Court inà Saroj Rani v. Sudharshan,[6] gave a judgment which was in line with the Delhi High Court[7] views and upheld the constitutional validity of the section 9 and over-ruled the decision given inà T. Sareetha v. T. Venkatasubbaiah. [8]It is a sad commentary that despite various courts including the Apex Court of the Country upholding the validity of section 9. Many jurists still have doubts with respect to the soundness of this section and demand its abolishment. Abolitionistââ¬â¢s View The abolitionists argue that it is a remedy that was unknown to Hindu law till the British introduced it in the name of social reforms. Even when the Hindu Marriage Act, 1955 was being passed in the Parliament, there were voices of scepticism regarding the efficacy of this remedy. [9] Sir J. Hannen inà Russell v. Russell[10] also vehemently opposed the remedy. Further, they are of the view any law that forces any person to live with another person is contrary to the value of the society. The remedy openly violates the fundamental right to life, privacy and equality hence is unconstitutional. Further more, there is frequently insincerity in the petitionerââ¬â¢s intention. The remedy is blatantly misused to achieve ulterior purposes other than reconciliation, the root cause being S. 13 (1-A)(ii) of the Hindu Marriage Act, 1955 and has created an additional ground of divorce. Yet another major problem with restitution petitions is that it is used as a defence for maintenance suits. This remedy has been repeatedly misused, abused and exploited. 11]Adding more, the procedure prescribed to enforce this decree under Order 21 Rule 32 of Civil Procedure Code, 1908 is also criticized on the ground that in India, where most of the population and especially women (wife) do not have actual possession over any property. You read "Family Law- Hindu Law" in category "Essay examples" In such cases, if a restitution decree is not complied with, then the court is required to ascerta in the share of the wife in the property of her husband, when it is not divided and arrive at her share in the property, but this involves cumbersome procedures. Difficulty also arises if the husband does not have a property in his name. Further, it is not correct to think that coercing a person that his property would be attached and sold away can change the attitude of the adamant spouse and make him obey the decree. Counter View However, in my opinion, section 9 of the Hindu Marriage Act is one of the most misunderstood sections of the Matrimonial law. Despite the controversy it has continuously been upheld by the Judiciary. Even the legislature through various committees and its reports has supported this section. All the reasons so stated by abolitionists can be easily encountered if this socially benefiting section is read in the right light and its essence is understood. It is imperative that a clear understanding of the section 9 is required because it is often invoked. First of all, it cannot be said that the concept of conjugal rights and that its embodiment in section 9 is foreign to the Indian culture and society. It may be borne in mind that conjugal rights. Such a right is inherent in the very institution of marriage itself. [12] The only thing is new is the embodiment of this concept which has been prevailing since antiquity. The prime objective of section 9 is to preserve the marriage. [13] According to the Hindu Marriage Act marriage is a civil contract and a religious ceremony. [14] It is a contract of the greatest importance in civil institutions, and it is charged with a vast variety of rights and obligation,[15] cohabitation being one of them. It is the very soul of marriage and this section enforces the right of cohabitation. If there is no reasonable ground for living apart, the court orders for cohabitation and enforces the Contract there is nothing wrong as the parties had voluntarily stipulated this at the time of entering into the marriage bond. [16]Section 9, in actuality, is a means of saving the marriage, it is in a sense an extension of sub-sections (2) and (3) of section 23 of the Act which encourage reconciliation by the court. It is the policy of the Act that the parties should live together and assist in the maintenance of marriages. [17] By enforcing cohabitation, the court is serving this purpose of the Act. Further, it is criticized on the ground that it allows the withdrawing spouse to take an advantage of his own wrong, which is against the scheme of section 23 and allows him/her to apply for a decree in case of non consummation of the marriage within one year of passing of decree. However inà Dharmendra Kumar v. Usha Kumari,[18] the Honââ¬â¢ble Court clearly stated that The expression ââ¬Å"in order to be aà ââ¬Ëwrongâ⬠à within the meaning of section 23(1) (a) the conduct alleged has to be something more than mere disinclination to agree to an offer of reunion, it must be misconduct serious enough to justify denial of the relief to which the husband or the wife is otherwise entitled to. [19]It is also often claimed to be gender discriminatory and violative of Article 14. T. Sareetha case[20] confirmed this view. It is obvious that the judge considered the entire question of restitution from the point of view of the woman. It seems that it has been overlooked that restitution of conjugal rights can also be claimed by the wife. It is relevant to state that the section is gender neutral as by the Amending Act 44 of 1964 either party to a marriage has been allowed to present a petition for divorce on the ground given in section 13(1-A). Even the party found guilty in restitution proceedings is entitled to petition for divorce under section 13 (1-A)(ii). There is complete equality of sexes here and equal protection of the laws. [21] Therefore this claim of abolitionist is incorrect. Section 9 is also criticized for being an instrument of forced sexual relation and hence being violative of right to privacy guaranteed under Article 21. But much contrary is its purpose. The remedy of restitution aims at cohabitation and consortium and not merely at sexual intercourse. [22] Inà Halsburyââ¬â¢s Laws of England[23]à it is observed: (cohabitation) aces not necessarily mean serial intercourse, which the court cannot enforce, so that refusal of sexual intercourse by itself does not constitute refusal to cohabit. [24] In support of this proposition the high authority of Lord Stowell inà Forster v. Forster,[25]à Orme v. Orme, [26] andà Rowe v. Rowe[27] may be cited. One thing is clear from Lord Stowellââ¬â¢s decision inà Forster v. Forster[28] and Halsburyââ¬â¢s statement of law that the Court does not and cannot enforce sexual intercourse. In cases like T Sareetha, [29] the concept of marriage is pictured as if consists as if it consists of nothing els e except sex. Chaudhary, J. ââ¬Ës over-emphasis on sex is the fundamental fallacy in his reasoning. He seems to suggest that restitution decree has only one purpose, that is, to compel the unwilling wife to ââ¬Å"have sex with the husbandâ⬠. This view was discarded long ago in as early as 1924 Sir Henry Duke President inà Jackson v. Jackson. [30]To say that restitution decree ââ¬Å"subject a person by the long arm of the to a positive sex actâ⬠is to take the grossest view of the marriage institution. [31]Therefore, it is fallacy to hold that the restitution of conjugal rights constituted ââ¬Å"the starkest form of governmental invasionâ⬠of ââ¬Å"marital privacyâ⬠. 32] Further, applying the standard that law has to be just, fair and reasonable as enunciated inManeka Gandhi,[33] section 9 said tries to bring the parties together. Whether to grant restitution decree would be just, fair and reasonable in the facts and circumstances of a given case is left to the court to be decided in its judicial discretion. What better guarantee can the law afford for the ââ¬Å"inviolability of the body and mindâ⬠of the wife and her ââ¬Å"marital privacyâ⬠[34] And therefore it can be safely stated that section 9 is not violative of Article 21. It also stated by critique that restitution decree serve as a stepping stone to divorce and is condemned to be a passage or passport to divorce. The reason behind the scheme of putting non consummation of marriage after one year of passing the decree of restitution of conjugal rights under section 13 of the Act is that the Indian Legislature believes that there should not be a sudden break of the marriage tie. It believes in reconciliation and that that cooling-off period is not only desirable but essential. If the marriage cannot be saved even after passing the decree of restitution it must be dissolved. A factual separation gives an easily justifiable indication of breakdown. [35] That is, under the Act it serves a double purpose. It first finds the fault and where it lies. Secondly it leads to the dissolution of the marriage, if there is no resumption of cohabitation. Further, recognizing non-consumption of marriage after 1 year of passing of Restitution Decree as a ground of divorce enables the aggrieved spouse to apply to the court for maintenance under section 25; and maintenance pendente lite may also be claimed by making out a case for the same as provided in section 24. This enables a wife, who does not desire disruption of the marriage or even judicial separation from the husband, to secure provision for her support by an order of the court under the matrimonial jurisdiction conferred on it, instead of filing a suit for maintenance under the law relating to maintenance now embodied in the Hindu Adoptions and Maintenance Act 1956. [36]People who are against the concept of restitution of conjugal rights argue that England which is the nation of origin of the concept has deleted this remedy from its legislation and India is still continuing it. The Law Commission, in their Fifty-ninth Report have- not recommended its abolition nor in their Seventy-First Report of 1978. The Commission was aware that it had been abolished in England under section 20 of the Matrimonial Proceedings Act 1970. However, it is germane to state that retaining this section all these years is not without reason. The truth is that the legislature has not accepted the breakdown theory in toto, as has been accepted in England. [37] Adding on, a recent writer[38] has suggested that ââ¬Å"the opinion of Derrett is more realistic and that the Hindu society is not mature enough to do away with the remedy. Its abolition would be like throwing away the baby with the bath-water. ââ¬Å"[39]It is also argued that the methodology adopted in execution of the decree as mentioned in the Code- of Civil Procedure (0-21 Rules 32 and 33) is erroneous as it provides for financial sanction in case of non fulfillment of this decree. It is to be remembered that marriage is also contractual in nature. Providing for a financial sanction in case of non fulfillment of contractual obligation is a common practice. Also that enforcement by attachment of property is provided by court where the disobedience to such a decree is willful i. e. s deliberate, in spite of the opportunities and there are no other impediments. 0 21, Rules 31 and 32 C. P. C. provide only a financial sanction to serve as an inducement by the court to effectuate restitution and serve a social purpose i. e. prevention of the break-up of the marriage. [40]Often the case ofà Russel v. Russel[41] is quoted by abolitionist, however the big ger picture as to why Lord Herschell called this remedy as barbarous is not brought in light. What he said and meant was that reasonable excuse, an essential for the decree of Restitution of Conjugal Right, was not confined only to the grounds of divorce. It can as well be ââ¬Å"something short of legal crueltyâ⬠which might constitute a reasonable excuse for refusing restitution. What was stated by him was that if the meaning of reasonable excuse was restricted to the grounds, then this remedy shall be barbarous. This is precisely what has been taken care of in India as the history of the Act would show. Section 9(2) as originally enacted provided that ââ¬Å"Nothing shall be pleaded in answer to a petition for restitution of conjugal rights which shall not be a ground for judicial separation or for nullity of marriage or for divorce. This created considerable difficulty. The Law Commission in its Fifty-Ninth Report recommended its deletion. It is now possible for the party to plead a reasonable excuse which may not necessarily be a ground either for judicial separation or nullity or divorce. So the Act was amended and by Act No. 68 of 1976 section 9 (2) was deleted. This brought the law in conformity with the opinion of Lord H erschell. It will, therefore, appear that Lord Herschellââ¬â¢s expression ââ¬Å"barbarousâ⬠was used in a different context. 42]Conclusion In summation, it may be stated that the grounds and arguments are baseless and they do not sufficiently prove that the Remedy of Restitution of Conjugal Rights is archaic, barbarous and violative of the basic Human Rights. It cannot be said that this remedy is unconstitutional. Section 9 has sufficient safeguards to prevent the marriage from being a tyranny. [43]In truth, it serves the social good purpose, by promoting reconciliation between the parties and maintenance of matrimonial. It protects the society from denigrating. And all the years that it has been enforce it has efficiently played itââ¬â¢s a role. References [1] Section 9 of the Hindu Marriage Act, 1955 reads as follows:- ââ¬Å"When either the husband or the wife has without reasonable excuse withdrawn from the society of the other, the aggrieved party may apply, by a petition to the district court, for restitution of conjugal rights and the court, on being satisfied of the truth of the statements made in such petition and that there is no legal ground why the application should not be granted, may decree restitution of conjugal rights accordinglyâ⬠.

The Art Of War Withstanding Time Essay Example For Students
The Art Of War: Withstanding Time Essay History credits the Chinese General Sun Tzu (circa 500 BC) with authoring a series of essays on the subject of war. Considered to be the earliest known treatises on the subject, Sun Tzu discussed military organization, defensive and offensive strategies as well as tactical maneuvering. Of his many essays his best known work, The Art of War, continues to be a reference for modern military strategists. Sun Tzus longevity is indebted mainly to Father J. J. M. Amiot, a French Jesuit priest, who brought a translation back to Europe shortly before the French Revolution. The nucleus of Sun Tzus principles for the conduct of war are: All warfare is based on deception and The supreme art of war is to subdue the enemy without fighting. In addition to Sun Tzus later western influence, his ideas spread throughout continental Asia and eventually to Japan. The Japanese were quick to adopt Sun Tzus precepts; eventually adding a few chapters to The Art of War of their own. In the end, Sun Tzus treat ises played a significant role in later Japanese military strategies and history.Although Sun Tzus work is credited to the Spring and Autumn Period, it is interesting to note the following era was that of the Warring States. Whether or not Sun Tzus treatises are simply a product of their time or an ominous indicator is difficult to discern. What is clear, however, is the dramatic nature of his subsequential historical impact. If you know the enemy and know yourself, your victory will not stand in doubt. If you know Heaven and know Earth, you may make your victory complete, Sun Tzu said. Being one of his most famous sayings, it has urged thousands and thousands of strategists to meticulously analyze their enemies and opponents. A stratagem of timeless value, appreciated by military leaders of all times. The military thought expounded in Sun Tzus Art of War is abundant, almost touching on all aspects of ancient wars. His thirteen chapters of principles and theories on war have been pr aised by militarists around the world. But the influence of his tactics has gone far beyond the military field. Today, his military theory is appreciated by businessmen and politicians as well. Highly applicable in the business world, Sun Tzus Art of War has become a major influence on business strategy, especially in Asia. We will write a custom essay on The Art Of War: Withstanding Time specifically for you for only $16.38 $13.9/page Order now Sun Tzus Art of War is written by Sun Wu and is set in the final years of the Spring and Autumn Period, 770-476 BC It is not only the oldest Chinese military work in existence but the oldest military theory in the world. Sun Wu, also called Chang Qiao, is known to have lived at about the same time as Confucius (the founder of Confucianism) and the Buddha (the founder of Buddhism). Tzu means man and was the title for famous men in ancient China. Hence, Sun Wu became Sun Tzu. Sun Wu, who was a native of Qi, caught King Ho Lus attention with his profound knowledge on military theory. The king appointed him to train a few troops as an experiment. The experiment was conducted with women instead soldiers. The king sent him one hundred and eighty beauties from the palace. Sun Wu divided them into two companies with the kings two favorite concubines as their leaders. He gave them axes and halberds and asked them if they knew their right from their left. The women assured him that they did. T hen with the roll of a drum he gave the order Turn right!? The women burst out laughing. Sun Wu said, If the rules are not clear and the orders are not clear, the commander is to blame. He repeated the instructions a third and a fourth time. Again the beauties from the palace burst out laughing. Then Sun Wu said, If the rules are not clear and orders are not understood, the commander is to blame. But when orders are clear yet not carried out, it is the officers who are to blame. Then he executed both company leaders. The king protested. Sun Wu replied, I have been appointed commander, and a general in the field is not bound by orders from his sovereign. Again he gave the orders, this time the women turned left or right and advanced or retreated exactly as they were told. After a period of time, the troops were in fighting trim and they would go through fire or water at the command of their general. King Ho Lu, now convinced of Sun Wus skills as a commander, made him his general. Sun Wu went on to defeat the mighty kingdom of Chu and the powerful states in the north, Qi and Jin. Sun Wus fame spread through all states and even further on. Sun Tzus Art of War spread throughout Asia and became the Koran for militarists. The Japanese hold high esteem for Sun Tzu and call him the Military Sage of the East. In Japan, managers and directors (commanders) have attached great importance to the application of Sun Tzus theories to the improvement of management and corporate strategy. In the second half of the 18th century, the first French translation of Sun Tzus Art of War appeared in Paris. Since then Sun Tzus works have been studied and appreciated by economics experts, military leaders, politicians and scholars. As a matter of fact Sun Tzus theories have had great influence among the general public too, especially in China and in the Chinese communities in Southeast Asia. .ueb42678c1b76a93dad097c5e46d68e29 , .ueb42678c1b76a93dad097c5e46d68e29 .postImageUrl , .ueb42678c1b76a93dad097c5e46d68e29 .centered-text-area { min-height: 80px; position: relative; } .ueb42678c1b76a93dad097c5e46d68e29 , .ueb42678c1b76a93dad097c5e46d68e29:hover , .ueb42678c1b76a93dad097c5e46d68e29:visited , .ueb42678c1b76a93dad097c5e46d68e29:active { border:0!important; } .ueb42678c1b76a93dad097c5e46d68e29 .clearfix:after { content: ""; display: table; clear: both; } .ueb42678c1b76a93dad097c5e46d68e29 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ueb42678c1b76a93dad097c5e46d68e29:active , .ueb42678c1b76a93dad097c5e46d68e29:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ueb42678c1b76a93dad097c5e46d68e29 .centered-text-area { width: 100%; position: relative ; } .ueb42678c1b76a93dad097c5e46d68e29 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ueb42678c1b76a93dad097c5e46d68e29 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ueb42678c1b76a93dad097c5e46d68e29 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ueb42678c1b76a93dad097c5e46d68e29:hover .ctaButton { background-color: #34495E!important; } .ueb42678c1b76a93dad097c5e46d68e29 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ueb42678c1b76a93dad097c5e46d68e29 .ueb42678c1b76a93dad097c5e46d68e29-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ueb42678c1b76a93dad097c5e46d68e29:after { content: ""; display: block; clear: both; } READ: Philip Morris EssaySun Tzus Art of War consists of thirteen chapters or thirteen principles, each having its own unique significance. A few quotes and interpretations follow. In Laying Plans, Sun Tzu says: War is a matter of vital importance to a nation, a matter relating to life and death of the people, survival or ruin of the sovereignty. Hence it demands serious study and under no circumstances can it be neglected.? In many ways this also applies to business in our times, as bold and controversial as it may sound. Knowing economics and using it as an instrument to produce wealth is such a matter. In appraising the outcome of a war one should analyze the actual situation and compare strengths and weaknesses by calculation, with respect to 5 fundamental factors: (1) morality, (2) weather, (3) terrain, (4) commander and (5) legal system. Morality is important. Only by conforming with morality can a commander have the support of the people and a manager the support of his employees. Only when united in heart and mind states and firms can be successful and prosper. In Waging war, Sun Tzu says: In chariot fighting the chariots taken should be mingled and used in conjunction with ours. The captured soldiers should be kindly treated and kept. This is called, using the conquered foe to augments ones own strength. Treating the defeated foe with sensitivity and gaining their respect is good. This principle is apt for mergers and acquisitions. In Planning A Siege Sun Tzu says: So there are five ways of knowing who will win. Those who know when to fight and when not to fight are victorious. Those who discern when to use many or few troops are victorious Here Sun Tzu is talking about timing and effiency. This concept is of uttermost importance in war. There is no doubt that timing and effiency also are key ingredients in a successful firm of our time. In Manoeuvre Sun Tzu says: Nor can one march through a country without knowing its mountains and forests, all the dangers and difficulties of the route and marshes. Knowing the terrain is advantageous. Knowing the industry and the market is extremely advantageous. The book, which holds numerous military strategies and accounts of the law of war, has long become a treasure of military science. Now, many people have discovered that the book contains ingenious ideas about management strategies, management decisions, market competition, organizational principle and selection and employment of personnel. Reading, understanding and applying appropriate parts of the rules and principles may do well. But one should be careful in obeying it completely. For we live in the midst of change and globalization. Having basic business principles to lean back on is good, but one must also be flexible. What is certain is that having one of the worlds most credible and trusted books on warfare in the briefcase can do no harm. If there is any place in the world where the principles of Sun Tzu are frequently used in management and business strategy it must be Asia, its place of birth. In the end all tremble at weapons; all fear death. Comparing others with oneself, one should not slay, nor cause to slay.

Women Empowerment in Rmg Sector Essays Women Empowerment in Rmg Sector Essay Women Empowerment in Rmg Sector Essay INTRODUCTION Bangladesh has a population around 160 million (July 2008 est. ). About 45% of them are still living below the poverty line. Bangladeshââ¬â¢s Human development index (HDI) is 139 (out of 177), ranking as the lowest in the Asian country list. GDP per capita (PPP US$) is 1,770, which make the countries HDI rank almost the same as the GDP rank. In Bangladesh Garment exports began in the late 1970s. But the scale was for a number of years modest up until the governmentââ¬â¢s 1982 New Industrial Policy to liberalize manufacturing, promote private participation, foreign investment and exports. During the last 10 years RMG has become one of the most important sectors of Bangladesh both from the domestic perspective and foreign earnings. Now RMG contributes about 76% of the foreign exports. Again it is also mentionable that about 80% of the workers in the RMG sector are female. Thus it is not contributing in earnings foreign currencies but also create employment opportunities for the women, which in turn contribute in the socio-economic development of Bangladesh. So it is very much essential to assess the current status of the women workers in RMG sector to take appropriate strategy to facilitates them by ensuring their rights so that this sector become more convenient for them. This will encourage the women and provide them the opportunity to contribute in development of Bangladesh. OVERVIEW OF RMG SECTOR IN BANGLADESH Bangladesh had no sign of the ready-made garment industry until late 1970s to early 1980s when foreign investors started their businesses in Bangladesh. The emergence of an export-oriented RMG industry in Bangladesh can be traced to a confluence of policy trends at global and national levels. The opportunity came to us as a result of quota system imposed on some developed countries. The idea of readymade garments came to our country in 1978 from South Korean company Daewoo. Daewoo trained some 130 officials of Desh Garments and had a 5-year contract with the same. But within one year 115 officials left Dash Garments and established their own business in the name of Reaz Garments, Paris Garments, Jewel Garments and Baishakhi Garments. In 1978 Reaz Garments expanded its operations into export market by selling 10,000 pieces of mens shirts worth French Franc 13 million to a Paris-based firm. It was the first direct exporter of garments from Bangladesh. Thus the RMG (Ready Made Garments) was introduced in Bangladesh, which has now become the biggest industry of the nation. Because Bangladesh initially had no quotas assigned to it and the cost of labor was extremely low, the RMG industry grew at a very high speed and now it contributes approximately 76% of the GDP of Bangladesh. The RMG sector of Bangladesh has helped the economic growth enormously. When the investors first came in, the government allowed 100% ownership for foreigners. The industry started with one factory in 1970; the number increased to eight factories in 1977. There were about 587 factories in 1984, 2650 in 1998 and 3300 in 2004. (Fritsch). After two decades of phenomenal growth the sector is destined to make a transition under phasing out of Multi Fiber Agreement (MFA) in 2005 through implementation of the Agreement on Textile Clothing (ATC). Only 30% of all the money that the country earns from garment factories stays in the country. The other 70% is used up in buying fabric and other raw materials that are not available in Bangladesh. Most garment factories are situated in Dhaka, Chittagong, Savar, Narayangong and Tongi. The major markets for Bangladesh have always been the United States, Canada and Europe and a few Caribbean countries, but recently Bangladesh has start exporting to other countries such as Australia and Japan on a smaller scale. Bangladesh exports 63 items (for example shirts, pants, etc. to other. Relatively strong GDP growth was almost doubled in value from 5. 6 per cent of GDP in the late 1980s to 12 percent in 2000. Here the RMG sector has played a leading role. Its share of the countryââ¬â¢s foreign exchange earnings has grown steadily from 4 per cent in the early 1980s to 41 percent at the beginning of the 1990s to 77 percent in 2001ââ¬â2002. Within RMG the share of knitwear increased even more dramatically from a negligible proportion in 1989ââ¬â90 to 25 percent of total exports in 2002ââ¬â2003, accounting for one-third of total RMG exports. Between 1978 and 1999 the RMG sector earned US$26 billion for the country, of which the value-added component was US$7. 6 billion or 29 per cent. In addition, a host of ancillary industries producing accessories have also emerged and grown alongside the garment industry. One estimate suggests that 80 per cent of garment accessories were locally produced, valued at $0. 5 billion a year (Bhattacharya and Rahman, 2000). Despite this spectacular performance, however, there is considerable pessimism about the future of the industry, particularly given plans to phase.

International business law Article Example | Topics and Well Written Essays - 500 words
International business law - Article Example The article relates to the material being used in class, specifically in terms of asserting the need to abide and observe human rights, especially in war-ridden areas. The news report disclosed that through these chemical attacks, ââ¬Å"the Assad regime continues to carry out war crimes in its slaughter of innocent men, women, and childrenâ⬠(Reuters par. 11). Even though the victims were noted to be rebels of the Syrian government, it is important to observe proper legal procedures in applying jurisdiction and justice, than resorting to chemical warfare that undermines their right to live. I strongly believe that each country face problems in terms of the ideologies professed by rebel groups which obviously run counter to government policies and legislation. However, as government officials, elected by the people, I affirm that resorting to unfair warfare tactics, like chemical warfare, grossly violates the rebelsââ¬â¢ right to express themselves and to live. As such, if these rebels also violate legal, moral, or ethical codes of conduct, they too, should be subjected to similar legal procedures that each and every citizen of the country is allowed to undergo. Therefore, the allegations reported that the Syrian government allegedly uses chemical warfare in rebel-held areas are obvious violations of human rights and should be rightfully examined by international courts. The fact that the government had already breached the chemical weapons agreement is already an indication of disrespect for justice and observance of human rights. The reason why I disagree to the Sy rian governmentââ¬â¢s alleged use of toxic chemicals in rebel-held areas is that the action obviously disrespects the right of these rebels to live. Further, by using these chemical weapons, unsuspecting and hapless victims include women and children, who are supposed to be protected from these abusive incidents. The rebels could just be

Cross Cultural Communications and Leadership Management Case Study
Cross Cultural Communications and Leadership Management - Case Study Example This explains the attitude of Hernandez when he tells Van West to take it slow, and that he is in control of the situation; he would be able to solve all the raised grievances. Managers in the Mexican settings use less participative style of management (Morris & Pavett, 1995). Judged from the actions of Hernandez; being out of the workplace as required. Stanford (1992) further argues that though American managers use participative management, Mexican managers are treated as figures of authorities, and Hernandez as a manager does not expect any control from Van west. To deal with Hernandez, Van West has to consider these Mexican settings. However, Hernandez might have used the friendly link between them to act in this particular way. The first thing for Van West to do would be to call Hernandez, and outline his expectations, though he had earlier informed him concerning his management styles. This would help West in reminding Hernandez of his roles, and the expectations in the product ion Department. When this does not work, Van West has to involve his authority as being the overall manager of the subsidiary, and replace Hernandez with a more competent manager. However, he must hold elaborate discussions with other departmental managers to support these strategic actions in streamlining the failing production department. Hofstede (1994), in his cross cultural theory and work related values critically examined how bosses behave, and interact with employees in an organization. Mexicans, according to this study have high scores in Power- Distance, Collectivism and Masculinity, and Uncertainty ââ¬â Avoidance. Employees from a high power ââ¬âDistance cultural background have a tendency to maintain professional distance away from their bosses. Bosses are therefore the ultimate decision makers, setting goals in an organization according to the Mexican culture (Hofstede, 1994). Bosses and managers in Mexico retain their local managerial cultural style in being au thoritative, and are viewed as father figures; meaning they are observed with due respect (Shimoni & Begmann, 2006). The ability to have authority in making decisions individually, and being less involved, or being less participatory in the daily factory operations makes these managers to be in less conflict with people on the factory floor. This guarantees these managers both power and authority, with the ability to act on personal decisions without consulting. The management- employee relation in the Mexican culture is a rather fascinating relation, which brings out important family values in Mexican management styles, and working environment. Hofstede (1994) explains the collectivism nature of Mexican culture, which translates to a strong sense of team working, and the need for social harmony. There is need for team based work, and harmonized groups as compared to individualistic competitions. Trompenaars (1994) further elaborates that Mexicans in being high on achievement dimens ion do not have preference in following any universal pattern rules. As managers are less participative, the relationship between employees and managers in Mexico is a vertical one, where managers are viewed as ââ¬Ëfathersââ¬â¢ to make decisions for their subordinates, who do not participate in the decision making process.

A Review Of Absorption Refrigeration Technologies Engineering Essay
A Review Of Absorption Refrigeration Technologies Engineering Essay Most of industrial processes use a lot of thermal energy by burning fossil fuels to produce steam or heat for various needs in the industry. After the processes, heat is rejected to the surrounding as waste. This waste heat can be converted to useful refrigeration by using a heat operated refrigeration system, such as an absorption refrigeration cycle. Electricity purchased from utility companies for conventional vapor compression refrigerators can be reduced and cuts down the need for expensive electricity from the central grid. The use of heat operated refrigeration systems help reduce problems related to global environmental, such as the greenhouse effect from CO2 emission from the combustion of fossil fuels in utility power plants. Another difference between absorption systems and conventional vapor compression systems is the working fluid used. Most vapor compression systems commonly use chlorofluorocarbon refrigerants (CFCs), because of their thermo-physical properties. It is t hrough the restricted use of CFCs, due to depletion of the ozone layer that will make absorption systems more prominent. However, although absorption systems seem to provide many advantages, vapor compression systems still dominate all market sectors. In order to promote the use of absorption systems, further development is required to improve their performance and reduce cost. The early development of an absorption cycle dates back to the 1700s. It was known that ice could be produced by an evaporation of pure water from a vessel contained within an evacuated container in the presence of sulfuric acid. In 1810, ice could be made from water in a vessel, which was connected to another vessel containing sulfuric acid. As the acid absorbed water vapor, causing a reduction of temperature, layers of ice were formed on the water surface. The major problems of this system were corrosion and leakage of air into the vacuum vessel. In 1859, Ferdinand Carre introduced a novel machine using wat er/ammonia as the working fluid. This machine took out a US patent in 1860. Machines based on this patent were used to make ice and store food. It was used as a basic design in the early age of refrigeration development. In the 1950s, a system using lithium bromide/water as the working fluid was introduced for industrial applications. A few years later, a double-effect absorption system was introduced and has been used as an industrial standard for a high performance heat-operated refrigeration cycle. However with the advent of cheaper vapor compression machines in the late 1960s and abundant and widespread availability of electricity lead to the vapor absorption machines taking a backseat. As a result we see that despite the fact that this technology has been around for almost 250 years, a viable alternative to the vapor compression machines for domestic use at a comparable cost has not been found. The aim of this paper is to provide basic background and review existing literature on absorption refrigeration technologies. A number of absorption refrigeration systems and research options are provided and discussed. It is hoped that, this paper should be useful for any newcomer in this field of refrigeration technology and generate in this area the same interest that the authors feel. PRINCIPLE OF OPERATION The absorption refrigeration system works with a binary solution consisting of refrigerant and absorbent. In Fig. 1(a)[1] two evacuated containers are connected to each other. The container on the left has liquid refrigerant while the right container has a binary solution of absorbent/refrigerant. The solution in the right container will absorb refrigerant vapor from the left one causing pressure to reduce. While the refrigerant vapor is being absorbed, the temperature of the remaining refrigerant will reduce as a result of its vaporization. This causes a refrigeration effect to occur inside the left container thus dropping its temperature. At the same time, solution inside the right container becomes weaker in concentration because of the higher content of refrigerant absorbed. This is due to the absorption process. Absorption process is an exothermic process; therefore, it must reject heat out to the surrounding in order to maintain its absorption capability. Whenever the solution cannot continue with the absorption process because of saturation of the refrigerant, the refrigerant must be separated out from the diluted solution.[1] Heat is usually the key for this separation process. The separation of the refrigerant is of paramount significance and most of the work recently has gone into making this as efficient as possible so as to increase the refrigeration effect. It is applied to the right container in order to dry the refrigerant from the solution as shown in Fig. 1(b).[1] The refrigerant vapor will be condensed by transferring heat to the surroundings. With these processes, the refrigeration effect can be produced by using heat energy. However, the cooling effect cannot be produced continuously as the process cannot be done simultaneously. Therefore, an absorption refrigeration cycle is a combination Fig. 1. (a) Absorption process occurs in right container causing cooling effect in the other; (b) Refrigerant separation process occurs in the right container as a result of additional heat from outside heat source. of these two processes as shown in Fig. 2.[1] As the separation process occurs at a higher pressure than the absorption process, a circulation pump is required to circulate the solution. Coefficient of Performance of an absorption refrigeration system is obtained from The work input for the pump is negligible relative to the heat input at the generator; therefore, the pump work is often neglected for the purposes of analysis. Fig. 2. A continuous absorption refrigeration cycle composes of two processes mentioned in the earlier figure. WORKING FLUID PAIRS FOR ABSOPRTION SYSTEMS The performance of an absorption system is heavily dependent on the properties of the working pair. We are mainly concerned with the thermal and chemical properties of the working fluids. The fundamental requirement is the absorbent/refrigerant combination, in liquid phase, must have a margin of miscibility in the operating temperature range of the cycle. The mixture should also be chemically stable, non toxic, non corrosive and should be able to maintain its fluidity in the operating range. Apart from these certain other desirable properties are: The difference in the boiling points of the pure refrigerant and mixture at the same pressure must be as large as possible. Refrigerant should have high heat of vaporization and high concentration within the absorbent in order to maintain low circulation rate between the generator and the absorber per unit of cooling capacity. Transport properties that influence heat and mass transfer, e.g., viscosity, thermal conductivity, and diffusion coefficient should be favorable. Both refrigerant and absorbent should be environmental friendly and low-cost, specially keeping in mind the increasing danger to the environment. The absorption refrigeration system, which has some advantages, such as silent operation, high reliability, long service life, simpler capacity control mechanism, easier implementation, and low maintenance, is widely acknowledged as a prospective candidate for efficient and economic use of solar energy for cooling applications. Also, the absorption refrigeration cycle is usually a preferable alternative, since it uses the thermal energy collected from the sun without the need to convert this energy into mechanical energy as required by the vapor compression cycle. In addition, the absorption cycle uses thermal energy at a lower temperature than that dictated by the vapor compression cycle. Many working fluids are suggested in literature. A survey of absorption fluids provided by Marcriss [2] suggests that, there are some 40 refrigerant compounds and 200 absorbent compounds available. However, the most common working fluids are NH3- H2O and LiBr-H2O. The binary systems of NH3- H2O and LiBr-H2O are well known as working fluid pairs to be used both in absorption heat pumps and in absorption refrigerators at present. Theoretical and experimental studies have been conducted to optimize the performance of absorption refrigeration cycles using NH3- H2O and LiBr-H2O as refrigerant- absorbent combination. The advantage for refrigerant NH3 is that it can evaporate at lower temperatures (i.e. from -10 to 0à °C) compared to H2O (i.e. from 4 to 10à °C), therefore, for refrigeration, the NH3-H2O cycle is used. NH3 has a high latent heat of vaporization, which is necessary for efficient performance of the system. It can be used for low temperature applications, as the freezing point of NH3 is -77à °C. Since both NH3 and water are volatility, the cycle requires a rectifier to strip away water that normally evaporates with NH3. Without a rectifier, the water would accumulate in the evaporator and offset the system performance. There are other disadvantages such as its high pressure, toxicity, and corrosive action to copper and copper alloy. However, water/NH3 is environmental friendly and low-cost. The use of LiBr-H2O for absorption refrigeration systems began around 1930. Two outstanding features of LiBr-H2O are non-volatility absorbent of LiBr (the need of a rectifier is eliminated) and extremely high heat of vaporization of water (refrigerant). However, using water as a refrigerant limits the low temperature application to that above 0à °C. As water is the refrigerant, the system must be operated under vacuum conditions. At high concentrations, the solution is prone to crystallization. It is also corrosive to some metal and expensive. Research has been performed for NH3-H2O systems theoretically and experimentally and these studies show that the NH3-H2O system exhibits a relatively low COP when compared to its LiBr-H20 counterpart.[1] Efforts are being made to search for better working fluid pairs that can improve system performance. It is proposed that NH3-LiNO3 and NH3-NaSCN cycles can be alternatives to NH3-H2O systems.[3] A study on the use of NH3-LiNO3 and NH3-NaSCN cycles by Jasim M. Abdulateef [3] reveals that ammonia-lithium nitrate and ammonia-sodium thiocyanate cycles give better performance than the ammonia-water cycle, not only because of higher COP values, but also because of no requirement for analyzers and rectifiers. Therefore, they are suitable alternatives to the ammonia-water cycle. Generally speaking, the performance for the ammonia-lithium nitrate and ammonia-sodium thiocyanate cycles are similar, with the latter being slightly better than the former. However, the ammonia-sodium thiocyanate cycle cannot operate at evaporator temperatures below 10à °C for the possibility of crystallization.[3] LITHIUM BROMIDE-WATER ABSORPTION SYSTEM There has been renewed interest to use thermally driven cooling systems from the air conditioning and process cooling fraternities. The lithium bromide-water absorption chiller is one of the front-runners due to the following reasons [4]: It can be thermally driven by gas, solar energy, and geothermal energy as well as waste heat, which help to substantially reduce carbon dioxide emission, this is its USP when it comes to process industries generating large amount of waste heat Its use of water as a refrigerant, which is easily available and cheap. It is quiet, durable and cheap to maintain, being virtually void of high speed moving parts; Its vacuumed operation renders it amenable to scale up applications. LiBr-H2O absorption chillers enjoy cooling capacities ranging from kilowatts (kW) to megawatts (mW) which match with small residential to large scale commercial or even industrial cooling needs. However they currently enjoy only a fraction of the extent of deployment as their vapor compression counterparts. Their major debilitating factors are a low Coefficient of Performance (COP), larger footprint and required headroom, corrosion and crystallization issues and stringent requirements of vacuum leak tightness over its design lifespan. Over the past 30 years, extensive efforts have been devoted to: Develop advanced absorption cycles which could work at low heat source temperature or recover more heat to improve system performance. Improve the design of major components such as generator and absorber to enhance their heat and mass transfer efficacy. Avoid crystallization problem and, Develop new and reliable working pairs. Problems in domestic use of LiBr-H2O absorption systems Even though the technology has been around for quite some time now its usage in domestic applications is hitherto seen. According to Kevin D. Rafferty [5] there is only one company (Yazaki, undated) currently manufacturing small tonnage ( While calculating the mass flow rate of the refrigerant for an assumed case of 1.5TR cooling, as is the requirement for most domestic air-conditioning applications, we obtained a very low mass flow rate in the order of a few gm/s. Also the ensuing pressure difference to maintain such working conditions led to a very high pressure ratio, to the order of about 50, between the absorber and generator. Upon market survey, (here in Pune, India) we discovered that pumps catering to such a low flow rate at this large a pressure differential were not readily available, some suppliers of customized pumps, however, did claim to be able to make such pumps, albeit at a very high cost. We explored the idea of then increasing the mass flow rate to higher than what was calculated for the required tonnage, but realized that increasing mass flow rate for evaporator of same tonnage would lead to un-evaporated refrigerant thus decreasing the COP of the system. During further study of the LiBr-H2O absorption systems we came across an interesting review on absorption chillers and their various configurations by Xiaolin Wang and Hui T. Chua [4], which provides a valuable insight. For the standard single effect system, simple structure and low cost are pursued. The single-effect double-lift absorption system are proposed and developed for the utilization of low temperature heat sources. However, multi-effect absorption systems are suggested to provide higher efficiency with a high temperature heat source. In order to increase the system performance and avoid crystallization problem, various heat and mass recovery systems, modifications to the generator and the absorber, different working pairs and additives have been developed. Furthermore hybridization of absorption chiller cycle with other cooling cycle(s) promises a higher overall performance as compared with that of each single constituent cycle. Single-Effect Absorption Chillers It consists of evaporator, absorber, generator, and a condenser. Its simplicity, small size, high reliability and lower maintenance cost are its advantages. While low cooling capacity, high weight and size and low COP are disadvantages Fig. 3. A schematic of a single effect absorption cycle in a Dà ¼hring plot Uchida from Hitachi developed a modular cascaded absorption chiller comprising of chiller units connected to one another in which chilled water flows through the chiller units in series while cooling water through parallel. [6] Water in chilled and cooling column flows in opposite direction and in absorber solution is sprayed in 1 or more stages. In this type of arrangement lower evaporator temperature can be achieved as compared to conventional arrangement. This results in lower amount of water circulation and higher efficiency due high average temperature difference, compact size, and lower capacity pumps. Inoue from Ebara Corporation integrated the absorber, evaporator, generator, and a condenser into a compact housing so that it can be used for used in residential operations. The arrangement is as shown in Fig. 4. A Absorber, C Condenser, E Evaporator, G Generator, X -Solution heat exchanger, SP Solution pump, RP Refrigerant pump Fig. 4. A single effect absorption chiller [7] This also resulted in reduced costs, compact size, less thermal stresses and low material usage. Inoue from Ebara Corporation in further bid to reduce size and increase COP used plate type heat exchanger in absorber and condenser. [7] In this water flows into the absorber and condenser in parallel and is distributed according to fluid resistance in each unit. This reduces mass flow rate and distributed flow results in elimination of complicated valve system. Problem of crystallization in chiller is avoided using popular J-tube technology. [4] Crystallization in system occurs in generator due to high concentration of LiBr resulting in blockage of flow to solution heat exchanger and will be accumulated in generator. When solution reaches certain level in generator, the hot refrigerant -weak solution will overflow via J-tube to the absorber and warms the refrigerant -strong solution immediately. This will warm the crystallized solution and dissolve them into the solution. Single-Effect Double Lift Absorption Chillers Fig. 5. A single-effect double lift cycle. Since single effect cycle requires the temperature of 90oC and above for proper working, for temperature lower than this results in significant drop in efficiency of the cycle. Therefore utilize to lower temperatures single effect single lift which can work for heat source between 70oC and 90oC and single effect double lift cycle works within waste heat source temperature down to 55oC was developed. A COP in the range of 0.35-0.7 is obtained. [4] Fig. 5. shows the construction of single effect double lift cycle consists of evaporator, absorber-1, generator-1, and a condenser forming single effect cycle the evaporator, absorber-1, generator-3, absorber-2, generator-2, and condenser constitute a double lift cycle. In this the solution from absorber1 is first is sent to generator-1 for steam generation, after this serially solution is sent generator-3 for further generation and refrigerant- weak solution is sent to absorber-1 . The steam generated in generator-3 is absorbed by the absorber-2 which then sent to the generator-2 for generation. The steam from generator-1 and generator-2 is sent in condenser to continue the cycle. The hot water in the system is supplied serially to the generator-1, generator-2, and generator-3. The cooling water flows to the condenser, absorber-1 and absorber-2 in parallel to avoid complicated control and unstable working conditions. The advantage of this system is high COP as compared single effect cycle since energy is utilized more effectively in this cycle. But due increase in number of components this has larger size as compared to single effect cycle. This system is commercialized by INVEN absorption GmbH. [4] Double-Effect Absorption Chillers Fig. 6. A double effect series flow type absorption cycle. This system is developed to increase COP of absorption chiller operating at temperature greater than 150oC since at this temperature the COP of single effect cycle is low. COP achieved in this cycle is in the range of 1.1 to 1.3. It was first patented by Loweth in 1970[8] and commercialized by Trane in the same year. Saito [9] from Ebara Corporation and Alefeld [10] improved and modified the double effect absorption refrigeration machine in 1980 and 1985, respectively. As shown in the plot above, double effect cycle consists of a high temperature and a high pressure generator. Steam generated from this generator is used to generate steam from low pressure generator through a heat exchanger. This steam is further sent to the condenser and evaporator for cooling. This arrangement is known as series flow arrangement. Therefore temperature differential utilization in double effect is more as compared to the single effect but heat rejected at the condenser and cooling temperature at the evaporator are at about the same temperature, hence COP is greater. Above mentioned arrangement works very close to crystallization temperature of LiBr-water solution and the high temperature generator operates at high pressure in order maintain requisite solution flow rate. To avoid solution pumping, the high temperature generator has to be sufficiently elevated to enjoy gravity assisted flow, resulting in higher head room. To avoid these problems, Hitachi developed a parallel flow double effect arrangement as shown below in Fig. 7. In this arrangement solution is separated after solution pump and is sent to high temperature generator through high temperature heat exchanger and to the low temperature generator, respectively. So, the operation condition is displaced further from crystallization point of solution. Flow rate of solution, pressure, elevation is also reduced as compared to series flow arrangement. Nagao from Hitachi disclosed a chiller which consists of an absorption section, an evaporator section, a condenser section, a generator section all of which are divided into two stages. The first stage evaporator second stage evaporator are arranged to be enclosed respectively by first stage absorber second stage absorber. Similar configuration is applied to the generator and condenser. This arrangement reduces heat transfer losses. Fig. 7. A double effect parallel flow type cycle. Hiro [11] from Sanyo Electric Co. disclosed a double effect absorption chiller, in which the connecting pipe conveying the liquefied refrigerant in the low temperature generator to the condenser is installed with an orifice together with a control valve so as to control the refrigerant pressure. A control circuit is connected to this control valve to actively control the refrigerant pressure and therefore control the solution concentration in the high temperature generator and the absorber. This control circuit facilitates the passage of the refrigerant to the condenser without stagnation during chiller start up or in the event of a sudden increase in cooling load. It is also capable of maintaining a suitably reduced pressure in the refrigerant during steady-state operation so as to achieve a higher operating efficiency. Recently Aoyama [12] from Ebara Refrigeration Equipment System disclosed an internal heat recovery scheme which aims to increase intrinsic COP of the machine and heat scavenging scheme which strives to extract more energy from heat source which drives the chiller. According to this invention, the refrigerant rich solution path leading from the absorber to the high temperature generator is divided into two routes. The first route is installed with one or two drain heat exchanger to scavenge the remaining enthalpy of the heat source powering the high temperature generator. The second route is installed with one or two regenerative heat exchanger to recover the heat of the hot and refrigerant-weak solution leaving the high temperature generator. Modeling and Simulation of LiBr-H2O absorption systems A recent paper by V. Mittal, K.S. Kasana and N.S. Thakur on Modeling and simulation of a solar absorption cooling system for India [13] simulated the model of a solar-powered, single stage, absorption cooling system, using a flat plate collector and water-lithium bromide solution. A computer program was developed for the absorption system to simulate various cycle configurations with the help of various weather data for the village Bahal, District Bhiwani, Haryana, India. The effects of hot water inlet temperatures on the coefficient of performance (COP) and the surface area of the absorption cooling component were studied. Simulation results are discussed in this section for the performance of a 10.5 KW solar driven lithium bromide absorption cooling system. Fig. 8. depicts the effect of the hot water inlet temperatures Ts on the system COP and flow ratio FR. It can be seen that an increase in this temperature resulted in the decreases of FR. This is due to increases in the mass fraction of concentration solution (XG). While with an increase in this temperature, COP increases. Fig. 8. The effect of the hot water inlet temperatures on the system COP and FR (Te = 280 K, QL = 10.5 KW, Tc = 306K) Figure 3 depicts the effect of the hot water inlet temperature on the surface area of the system components. It can be seen that increase in this temperature results in the decrease of the absorber and solution heat exchanger surface area. As flow ratio decreases, the thermal energy extracted from the absorber also decreases and hence the temperature of the absorber increases, which further resulted in the increase of logarithmic mean temperature difference (DTm) in the absorber and solution heat exchanger. By decreasing the heat capacity and increasing DTm, heat transfer surface area normally decreases in these components. Fig. 9. The effect of the hot water inlet temperatures on the surface area of the system components (Te = 280 K, QL = 10.5 KW, Tcool, in = 291 K) From this study the following conclusions were made: The hot water inlet temperature is found to affect the surface area of some of the system components. Increasing this temperature decreases the absorber and solution heat exchanger surface area, while the dimensions of the other components remain unchanged. Although high reference temperature increases the system COP and decreases the surface area of system components, lower reference temperature gives better results for FNP than high reference temperatures do. For this study, a 353 K reference temperature is the best choice. This paper thus provides a general idea to anyone looking to build a model of a vapor absorption system, about the generator temperature needed and its effect on the flow rate and COP. AMMONIA-WATER ABSORPTION SYSTEM The working of ammonia-water absorption refrigeration system is based on theà simple vapor absorption refrigeration systems. In this system ammonia is used as the refrigerant and water is used as the absorbent. The ammonia-water absorption system is used in the domestic as well the commercial applications where the requirement of the temperature is below 0 degree C. The major advantages of the ammonia-water solution are: Water has strong affinity for ammonia and they are soluble with each other in wide operating conditions that occur in different refrigeration applications. The ammonia-water solution is highly stable and works well with many materials. Ammonia is a common chemical and it is easily and cheaply available. However the system has a few disadvantages too some of which are: Except copper and its alloys that get corroded in the presence of ammonia. Due to its toxicity its applications are limited. Due to the fact that some of the water in the generator also boils off with the ammonia and escapes as vapor, a rectifier is needed to remove this water vapor before it enters the condenser. This adds to the expense and complexity of the design. The COP of the ammonia-water systems is slightly lower than their LiBr-water counterparts. Fig. 10. Schematic of a typical ammonia-water absorption system. Domestic use of ammonia-water absorption systems Unlike the LiBr-H2O absorption system, the ammonia-water absorption system has found widespread use in the domestic use market. These refrigerators are very popular as car fridges used in SUVs and RVs. Many companies are involved in the manufacturing of such equipment. Electrolux was amongst the first companies to start manufacturing absorption refrigerators for commercial use. One of the main issues with the early domestic absorption refrigerators was that the water would get crystallized and the whole setup would then need to be inverted for a few hours to get the system working again. Such old models of absorption models are available in scrap; however most of them are not in working condition. We came across one such model ourselves, however even on extensive research the exact composition of the water ammonia mixture or the operating pressure was not found. Most people do not recommend recharging of these old units as they are factory sealed and compositions are not known, however some people have tried recharging and obtained successful results. Simulation of absorption diffusion Solar refrigeration systems A study was carried out by B. Chaouachi and S. Gabsi [14] for the design and the simulation of an absorption diffusion refrigerator using solar as source of energy, for domestic use. The design holds account about the climatic conditions and the unit cost due to technical constraints imposed by the technology of the various components of the installation such as the solar generator, the condenser, the absorber and the evaporator. Mass and energy conservation equations were developed for each component of the cycle and solved numerically. The absorption diffusion refrigerating machine is designed according to the operation principle of the refrigerating machine mono pressure invented by Platern and Munter. This machine uses three operation fluids, water (absorbent), ammonia (Refrigerant) and hydrogen as an inert gas used in order to maintain the total pressure constant. The study yielded some interesting conclusions. The operating boundaries of the system were examined by conducting simulations for various values of the generator temperature, TG, the evaporator temperature, TE, the pressure of the system, P and the generator heat input, QG. The operation ranges were found to be: 5 Fig. 11. COP vs. to generator temperature for various pressures of the system (ÃŽà ¾r=0.45, Te=273K) Fig. 11. presents the COP vs. the generator temperature for different pressures of the system for a fixed rich concentration and evaporator temperature. It shows that the COP decreases as the generator temperature increases and it increases when the pressure increases too. This is may be attributed to the fact that a smaller amount of ammonia was separated from the ammonia-water solution and thus more solution had to be circulated so as to maintain the refrigerant flow rate in the condenser. It thus recommended that pressure of the system as high as possible. Fig. 12. OP vs. the evaporator temperature (ÃŽà ¾r = 0.4, P=12.5 bars) The Fig. 12. shows that the COP decreases as the generator temperature increases. It was also found that the higher the evaporator temperature, the higher COP, i. e. that more heat was absorbed in the evaporator. There are thus opposing demands for the evaporator temperature; on the one hand, it should be high enough (depending on the desired cooling capacity) to yield a higher COP, while a lower evaporator temperature would yield better cooling. Thermodynamic simulation of Solar absorption refrigeration systems Another thermodynamic simulation carried out by Antonio J. Bula [15], for an ammonia water solar absorption system. The operating conditions chosen were: Tg = 70 90à °C Tc = 30 à °C Ta = 25 à °C Te = 5 à °C
