Methods to Improve the Performance of VCR Cycles using R-1270 as Refrigerant

There are several ways of improving the performance of a vapor compression refrigeration cycle. This paper provides you the various existing as well as some new and innovative methods which improves the Coefficient of Performance of Vapour Compression Cycle by using R-1270 as a refrigerant. A thermodynamic model is developed and parametric study of each system keeping the Evaporator and Condenser temperature same in all the cases. It was found that the Ejector Expansion Refrigeration system achieves the significant improvement in coefficient of performance as compared to other system. Use of an ejector as expansion device is one of the alternative ways. One of the finest, simple and economic way to maintain all these aspects is the use of Ejector as an expansion device by replacing expansion or throttling valves. Complete cycle named as Ejector Expansion Refrigeration System with Liquid Vapour Heat Exchanger where the mixing takes place inside the mixing chamber of Ejector. The refrigerant used is an Eco-Friendly refrigerant Propylene (R1270). Although many advancements are implemented in Ejector Expansion Cycle but placing a liquid vapour heat exchanger in between constant mixing chamber is novel idea both in the field of academic and practice.
