Abstract

In this study, micro channel heat exchangers are applied to residential heat pump air-conditioning systems. The performance of the heat pump system using micro channel heat exchangers is compared with that of the baseline heat pump system using tube & fin heat exchangers. It shows that for the residential heat pump air-conditioning system, the system capacity can increase by 4% by using micro channel heat exchangers, and the system efficiency such as SEER and HSPF can increase by 2% and 1%, keeping the face area of the heat exchangers the same. The weight of heat exchangers can be reduced by 44%. And the refrigerant charge can be reduced by 51%.
