Performance of a Split-Type Air Conditioner with Natural Refrigerant R1270 to Replace R22

Abstract:

A natural and environment friendly refrigerant propylene (R1270) is proposed as a substitute of R22 in the residential air conditioner. The experiments on the cooling performance of the air conditioner with R1270 and R22 were respectively conducted on an existing enthalpy potential bench, during the degree of superheating keep constant and refrigerant charge directly on the conditioner, also the effect on system performance in the condensing temperature was tested, it is founded that the cooling capacity of R1270 air conditioner was 96% that of R22 air conditioner while the COP of the former increased, and the refrigerant charge amount of R1270 was 56.8 % lower than R22.
