摘要
传统空气源热泵除霜方式不能满足室内温度及人体热舒适度要求。对不同除霜模式进行总结,从除霜工况对空气源热泵机组运行效率影响的角度进行分析,介绍热泵机组的研究现状,提出了一些不足以及相关的改进方法,为今后进一步除霜问题的研究提供了参考依据。
Traditional air source heat pump system can' t meet the demand of indoor temperature and thermal comfort of human body. This paper summarizes some different defrosting mode of the Air Source Heat Pump system( ASHPs) modes,introduces current research status of the system and defects,puts forward relevant proposals and ways to improve from the effect of defrosting on the operating efficiency of the heat pump system. This paper may provide a reference for later research for ASHPs.
