Abstract

A vapour compression refrigeration cycle is generally applicable in both heat pump and refrigerator as per their purpose. Space heating as well as hot water production using heat pumps is most proven energy efficient method. The further investigations on performance of vapour compression refrigeration cycles acting as heat pumps has been focused by several researchers so that heat pumps will be able to achieve optimal heat transfer capabilities on vapour compression refrigeration cycles . We are presenting this paper for carried out various researches on the performance of different parameters on VCR system with different refrigerants. Research carried out by different authors uses different type of capillary tubes in different …show more content…

Refrigerators and heat pumps are essentially the same devices; they differ in their objectives only. The objective of a refrigerator is to maintain the refrigerated space at a low temperature by removing heat from it. Discharging this heat to a higher-temperature medium is merely a necessary part of the operation, not the purpose. The objective of a heat pump, however, is to maintain a heated space at a high temperature. This is accomplished by absorbing heat from a low-temperature source, such as well water or cold outside air in winter, and supplying this heat to a warmer medium such as a house. Refrigerator and heat pump are essentially the same device but they differ in their objective only. The objective refrigerator is to maintained the refrigerated space at a low temperature by removing heat from it, however objective of heat pump is to maintained heated space at a high temperature. A vapour compression refrigeration system is now a days used for all purpose refrigeration. It is generally used for all industrial purpose from a small domestic refrigerator to a big …show more content…
