摘　　要：空气源热水器在我国的发展越来越迅速,而空气源热泵热水器在冬季由于蒸发器表面结霜,霜层增厚导致空气流动受阻,影响热水器的制热能力。准确的进行结霜程度的判断以及化霜的设置是影响空气源热泵热水器正常运转的首要因素。本文提出一种化霜条件的判断及设置,从实验上验证该化霜设置在实际运行中的合理性及准确性。In our country,the development of air-source water heater is rapidly.But in winter,when the evaporator surface of the air-source heat pump water heater frost,the air flow is constrained because of the frost layer thickness,which affects the heating capacity of water heater.Accurately assess the degree and frosting defrosting setting is the primary factor affecting air-source heat pump water heater running.The paper forwards a judgment and sets a defrosting condition,from the experiments,with the defrosting arranged in the actual operation for testing the rationality and accuracy.
