摘　　要：研究了开式空气源热泵烘干系统排湿过程的热湿平衡,定义了除湿(显)热负荷和排湿效率。定义了排湿能效比,并进一步提出了排湿能效比的计算方法、测试方法和影响因素。指出排湿能效比受不同天气情况影响较大,存在热回收装置时,排湿能效比与风量成反比。对于烘干排湿系统的设计具有参考意义。The heat and humidity balance of open air source heat pump drying system was studied,the dehumidification(sensible)heat load and dehumidification efficiency were defined.The dehumidification efficiency is defined and the calculation method,test method and influencing factors of energy efficiency ratio of dehumidification were further proposed.It is pointed out that the efficiency ratio of dehumidification is greatly affected by different weather conditions.When there is a heat recovery device,the efficiency ratio of dehumidification is inversely proportional to the air volume.This article has reference significance for the design of drying and dehumidification systems.
