Abstract

Abstract: As a natural working medium, R290 has become important alternative refrigerant in the field of room conditioning due to its good environmental performance. Compared the thermal performance of R290 and R32, and verified the ability and energy efficiency of two variable frequency air conditioners with the same configuration of heat exchangers by experimental comparison. The results show that when the charging amount of R290 is only 54% of R32, the R290 air conditioner can achieve the same ability and the same level of energy efficiency with R32 air conditioner by debugging. Proved R290 refrigerant can be a good substitute for R32 refrigerant.

Key words: R290, R32, Variable frequency air conditioning, European standard
