摘　　要：以湿毛巾为研究对象,在自行研制的远红外辅助热泵干燥装置上进行了干燥系统的性能测试。比较了热泵(HP)干燥和加热功率为500、1 000和2 000 W的远红外(FIR)辅助热泵干燥条件下,干燥室进、出口空气温度和相对湿度,以及干燥对象不同部位的温度在干燥过程中的变化情况。与单一热泵干燥相比,不同功率远红外辅助热泵干燥的除湿能力提高8.1%～22.2%。结果表明远红外辅助热泵干燥可以有效缩短干燥时间,提高干燥效率。Taking wet towels as the research object,a far-infrared-assisted heat pump dryer was designed and manufactured.Wet towels were dried by using a heat pump（HP） dryer combined with far-infrared radiation（FIR） with the power of 500,1 000 and 2 000 W.Changes of drying chamber inlet air temperature,outlet air temperature,inlet air humidity,outlet air humidity,inlet sample temperature,middle sample temperature and outlet sample temperature were all studied.The experiments were conducted under pump drying and far-infrared-assisted drying with different powers.The results showed that compared with the pump drying treatment,the dehumidification capacity was improved effectively,with values of 8.1% to 22.2%.The present data suggested that far-infrared-assisted heat pump drying could shorten the drying time,improve the drying efficiency.
