【Abstract】 This paper proposed a physical model of dynamic frosting processes on the air coil of air-source heat pumps. The frost accumulation on the coil fin surface and the heating characteristics of heat pump units were numerically modeled. The effects of ambient conditions, fin pitch, and the number of tube rows on frosting feature and heating performance of units were analyzed in detail.更多还原
