摘要：
The advantages and disadvantages of the current defrosting control means are described. A new method is presented that considers the dropping value of heat transfer coefficient of the evaporator in air-source heat pump as the key to judge whether to begin to defrost or not. The details of judgment are provided with a sample computation.
