Study on the Method of Reducing Discharge Temperature of Refrigerant System with R32
This paper analyzed theoretically the change of refrigerant system after replacement of R410 with R32. Such replacement led to the increase of the discharge temperature of the system. The method of gas refrigerant injection was proposed to reduce the discharge temperature. Some experiments were made to investigate the variation of refrigerant system on charging rate
capacity
COP
discharge temperature after the replacement of R410A with R32. The results showed that
comparing with R410a system
the capacity
COP and discharge temperature of R32 were increased
and the R32 system with gas refrigerant injection can reduce effectively the discharge temperature
andincrease the capacity and COP. It can be concluded that R32 is a promising refrigerant candidate
and the limitation brought by high discharge temperature of R32 can be broken with the gas refrigerant injection system.
