摘　　要：在热泵干燥领域,空气源热泵技术经常用于干燥各类物料。应用空气源热泵干燥消防水带的技术逐渐成熟,但仍存在干燥效率低、干燥时间长、难以干燥透彻等问题。为解决热泵干燥后期循环空气湿度大的问题,提高消防水带干燥效率、单位能耗除湿量(SMER)和单位时间除湿量(MER),设计并研发了一种热泵-红外联合干燥装置,同时利用Design expert软件验证并确定适合消防水带干燥的最佳工况。试验结果表明,红外辐射温度为36℃、热泵红外转换时间为1.6 h、风机送风速度为2.2 m/s为最佳试验工况,此时系统总耗电量为6.57 kWh、SMER为1.32 kg/kWh、MER为2.91 kg/h。与传统热泵干燥水带技术相比,总耗电量基本不变,SMER提高58.3%,MER提高61.6%,综合干燥效果明显提升。In the field of heat pump drying,air source heat pump technology is often used to dry various materials.The technology of drying fire hoses using air source heat pump is gradually mature,but there are still problems such as low drying efficiency,long drying time,and difficult to dry thoroughly.In order to solve the problem of high humidity of circulating air in the later stage of heat pump drying,and improve the drying efficiency of fire hoses,Specific Moisture Extraction Rates(SMER)and Moisture Extraction Rates(MER),a heat pump-infrared ray combined drying device was designed and developed,and the Design expert software was used to verify and determine the best working conditions suitable for fire hose drying.The experimental results show that the total power consumption of the system is 6.57 kWh,SMER is 1.32 kg/kWh,and MER is 2.91 kg/h when the infrared radiation temperature is 36℃,the conversion time from the heat pump to infrared ray is 1.6 h,and the fan air supply speed is 2.2 m/s.Compared with the traditional heat pump drying hose technology,the total power consumption is basically unchanged,the value of SMER is increased by 58.3%,the value of MER is increased by 61.6%,and the comprehensive drying effect is significantly improved.
