Popis:	The purpose of this study was to test the performance of hydrocarbon refrigerant (R-1270) to replace R-32 refrigerant. The refrigerant R1270 is a propylene-base refrigerant (C3H6), while R32 is a synthetic refrigerant. Both refrigerants were tested on residential air conditioning systems with similar specifications. At pressure of 100 psig and external air temperature of 25 °C, the Coefficient of Performance (CoP) and Energy Efficiency Ratio (EER) of R32 were better than those of R32. The electrical power consumption of R1270 was 12.5 % more efficient than R32. In terms of volume used, R1270 required was 53.5 % lower than that of R32. The air temperature coming out of the evaporator of R1270 was 1 °C lower than that of R-32. This research showed that R-1270 could be used to replace R-32 effectively.
