Abstract

In this study, a theoretical analysis is been carried for the application of the alternative refrigerant with low global warming to R22 in small air conditioning unit. The refrigerants investigation is R290, R600, R600a and R1270. The system mathematical models are running by using EES program .The results show that at any working condition the R600a give the identical performance to R22 and can be use in new units that required compressor modification. So the system with R1270 has less system performance reduction from R22 By 4.3% and can be used as retrofitting alternative refrigerant for current units without modification.
