摘　　要：以应用最广泛的封闭式热泵干燥装置为例,建立了其SMER计算方程。在此基础上,对SMER随干燥器进口空气温度、干燥器出口空气温度和蒸发器出口空气温度而变化的规律进行了计算和分析。结果表明,其他两个参数一定时,SMER随干燥器出口空气温度上升而降低,随蒸发器出口空气温度上升而增加,但当干燥器进口空气温度取适宜值时,SMER存在最大值。The SMER equation is deduced for the most widely used close-circuit heat pump dryers, and based on the equation, the changes of SMER with air temperatures changes at the dryer inlet, the dryer outlet and the evaporator outlet are calculated and analyzed. It shows that when the other two parameters are given, SMER descends with the ascending of air temperatures at the dryer outlet, ascends with the ascending of air temperatures at the evaporator outlet, hut a maximum SMER exists for a suitable air temperature at the dryer inlet.
