Abstract


In this paper R32 and R410A were filled into the two-stage compression system with an enhanced vapor injection device so as to carry out some experimental studies and test of the performance. The results show that when being used in the air-source heat pump water heater with the enhanced vapor injection device, R32 has better operating effect and higher COP. Therefore, environment friendly refrigerant R32 can effectively improve the poor heating capacity of the air-source heat pump water heater under the low-temperature working conditions.
