Experimental Study Comparing the Efficiency of Heat Pump Hot Water Using Refrigerant R32 and Refrigerant R410A

Tran Quang Danh

Abstract: The paper presents the research results of experimental heat pump hot water (HPHW) using new refrigerant R32, more friendly to the alternative environment for hot water supply heat pump systems using the current R410A on the market. Experimental results show that the new refrigerant pump system R32 has a lower CO2 emission factor than the system using R410A refrigerant. Hot water heating time of R32 heat pump system is 25.86 minutes shorter than the system using R410A medium with 27.78 minutes with hot water temperature required to reach 50 C
