摘　　要：采用计算机模拟的方法建立了空气源热泵冷热水机组室外换热器结霜工况下的数学模型 ,将结霜模型与换热器传热特性模型有机地结合起来 ,并考虑了室外换热器中制冷剂两相流的影响。The frosting on heat exchanger outside of air source heat pump heating/chilling unit used in winter is an important cause to influence on its more widely being used. The mathematical model of heat exchanger outside of air source heat pump heating/chilling unit is developed,which combines model of frosting and character of heat transfer and considers the influence of two phase areas of refrigerate in the exchanger outside.
