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.
The drying performance of closed heat pump dryers was studied, and the performance of the heat pump system was studied by using COP of performance of heat pump system, SPC of dehumidification power, MER of unit time, SMER of unit energy consumption, etc. The results show that heat pump The COP value of the system increases with the moisture content of clothing at low loads and reaches the maximum at 45% moisture content at higher loads. The SMER value of the heat pump drying system increases with the load of clothes The moisture content increases and increases at higher load increases with the increase of moisture content and basically maintained at a higher value; heat pump system and heat pump drying system interact with each other constraints, heat pump system COP value and Heat pump drying system SMER value can not reach the maximum at the same time.
