摘要
风冷热泵的一个主要问题是结霜对换热器传热性能和机组正常运行造成的影响。为了正确设计积霜换热器和选择除霜控制方式，保证机组高效运行，必须深入地了解霜对换热器的影响。
The efect of frosting on heat exchanger's properties and even on normal operation of ASHP is a major problem. In order to design heat exchanger with frost and to select defrosting control manner correctly, and to ensure the unit operating effectively, it is necessary to recognije the previous effect.
