摘　　要：热泵干燥设备是一种新型的消防水带干燥设备,为解决热泵干燥设备的能源浪费等问题,研发了一款采用空气源热泵技术并集成旁通排气系统的消防水带热泵干燥设备。为评估旁通与排气策略对消防水带干燥特性的影响,设计了一项针对消防水带热泵干燥装置的性能测试试验。试验结果表明,实施排气策略后,系统制热系数提高了2.8%,单位能耗除湿量提高了13.5%;实施旁通策略后,系统制热系数提高了8.5%,单位能耗除湿量提高了24.5%。研究结果表明,与传统的开闭一体式干燥模式相比,采用旁通排气联合操作模式在节能方面效果更显著。Heat pump drying equipment is a new type of fire hose drying equipment,in order to solve the problem of large energy waste of heat pump drying equipment,a fire hose heat pump drying equipment with bypass exhaust based on air source heat pump has been developed.In order to evaluate the influence of bypass and exhaust strategies on the drying characteristics of fire hoses,a performance test of fire hose heat pump device was designed.The test results show that after the implementation of the exhaust strategy,the heating coefficient of the system is increased by 2.8%,and the dehumidification capacity per unit energy consumption is increased by 13.5%.After the implementation of the bypass strategy,the heating coefficient of the system increased by 8.5%and the dehumidification capacity per unit of energy consumption increased by 24.5%.The final results of the study show that compared with the traditional open-close integrated drying mode,the combined operation mode of bypass and exhaust is more effective in terms of energy saving.
