The characteristics of ASHP under unnecessary defrosting phenomena were studied. Energy loss for two kinds of unnecessary defrosting phenomena was quantified. A method was proposed to predict times of unnecessary defrosting operations. Performance loss of unnecessary defrosting was evaluated for typical cities in China. It indicates unnecessary defrosting processes should not have been ignored.
