闭式热泵干衣机干衣性能实验研究

摘要

The performance of closed heat pump dryer was investigated.The indexes of coefficient of performance of heat pump systems COP,specific dehydration power consumption SPC,average specific dehumidification MER,specific dehumidification SMER and so on were used to study its performance.The results indicate that the value of COP increases with the increase of moisture content at the lower load,and it arrives at the highest value when the moisture content is 45％ at the higher load.The SMER of heat pump and drying system increases with the increase of moisture content at the lower load,and it basically remains at a high value when the load is higher.Because the heat pump system and drying system restrict and interact with each other,the values of COP and SMER can't reach its highest value simultanuously.%对闭式热泵干衣机干衣性能进行实验研究,采用热泵系统性能系数COP、除湿能耗比SPC、单位时间除湿量MER、单位能耗除湿量SMER等指标考察其性能.研究结果表明,热泵系统的COP值在低负载时随着衣物含水率的增大而增大,在较高负载时,在含水率为45％时达到最大值；热泵干燥系统的SMER值在低负载时随着衣物含水率的增大而增大,在较高负载时随着含水率的增大而增大且基本维持在较高的数值；热泵系统和热泵干燥系统相互影响相互制约,热泵系统的COP值与热泵干燥系统的SMER值不能同时达到最大.
