Review on Experimental Investigation of Enhancement in Cop of Vapour Absorption Cycle

The improvement in the quality of life has increased the demand for Refrigeration systemsthroughout the world. In the, vapour absorptionrefrigeration systems are looks uponwith renewed interest as and they workon heat operated system with environment friendly working fluids.In the review of literature has been foundto enhanceand investigatethe performance of vapour absorption system.For that the modification in this VAR cycle is the important parameter to improve the COP of the system.For that we using water cooled type condenser instead of the air cooled condenser.The water cooled absorber and condenser areUtilizing the generator-absorber heat exchange principle in ammonia-water system reduces the generator heat input and thereby enhancing the system coefficient of performance. The effects of refrigeration system parameters namely, evaporating temperature (Te), condensing temperature (Tc) and massof the refrigerant (m), on the performance of the system using theoretical models
