摘　　要：空气源热泵冷热水机组冬季运行时 ,空气侧换热器表面结霜是影响其应用和发展的主要问题 .通过对霜形成机理的分析 ,建立了空气源热泵冷热水机组空气侧换热器的结霜模型 ,分析了空气的温度、相对湿度、迎面风速等对结霜的影响 ,得到了结霜量的变化规律 。Frosting on the surface of airside exchanger is a major problem having its effect on the application and development for air source heat pump unit. From the analysis of frosting mechanism, a mathematical model was established for airside heat exchanger of the water chiller/heater of air source heat pump, simulates and analyzes the influence of temperature and relative humidity of outdoor air, windward speed on frosting growth. The law governing frosting growth are simulated, and suggestions were made on how to analyze the performance of air source heat pump with frosting and measures were propose for control of defrosting.
