Summary

In this study, the performance of heat pump cycle using low GWP refrigerant mixtures of HFC-32 and HFO-1123 was evaluated experimentally. The experimental system was a water heat source vapor compression cycle, mainly composed of an inverter-controlled and hermetic-type scroll compressor, an oil separator, a double-tube-type condenser, a liquid receiver, a solenoid expansion valve, and a double-tube-type evaporator. Three kinds of refrigerant mixtures of HFC-32/HFO-1123 with 58/42 mass% (GWP=393), with 46/54 mass% (GWP=312) and with 42/58 mass% (GWP=285) were tested at heating mode as well as at cooling mode. It was found that the COP of HFC-32/HFO-1123 mixture (58/42 mass%) was almost the same as that of R410A, while that of HFC-32/HFO- 1123 mixture (42/58 mass%) was a little lower than that of R410A in both heating and cooling modes. It was also shown that the system COP of HFC-32/HFO-1123 mixtures exceeded that of R410A. In conclusion, the tested mixtures of HFC-32/HFO-1123 would be candidates of the alternative to R410A if the design of compressor and heat exchangers were optimized.
