摘　　要：泵驱动回路热管能量回收装置是一种空调排风能量回收装置,它综合了中间热媒式和回路热管式换热器的优点,能够适应管路布置复杂的场所。为研究该装置的性能,搭建了泵驱动回路热管能量回收装置实验系统,提出了换热量、温度效率、性能系数3个装置性能评价参数,考虑室内外温差ΔT、工质质量流量m、换热器换热面积A和工质种类4种因素对该装置性能的影响。通过测试不同室内外温差、工质质量流量、换热器换热面积下装置的换热量、温度效率、性能系数的数值,得出它们之间的变化关系,得到最优运行方案,为该类装置的设计和运行提供指导和参考。Pump-driven loop heat pipe energy recovery device is an air conditioning energy recovery device, which integrates the advantages of intermediate heat medium and loop heat pipe heat exchangers and is suitable for complex pipeline layouts. In order to study the performance of the device, an experimental system for the pump-driven loop heat pipe energy recovery device was set up, and three performance evaluation coefficients, heat exchange, temperature efficiency,and performance coefficient were proposed, and the effects of four factors on the performance of the device, including temperature difference ΔT, mass flow rate m, heat exchange area A, and working medium, were considered. By testing the values of heat exchange, temperature efficiency, performance coefficient under different temperature differences, mass flow rate, and exchange area, the relationship between them and optimal operation scheme were obtained, which provided guidance and reference for the design and operation of such devices.
