摘要

提出一种泵驱动回路热管能量回收装置，用于回收公共建筑空调系统排风的能量，降低处理新风的能耗，并搭建实验平台，测试该装置在两种工况下的性能，分析工质质量流量、换热器换热面积和换热器迎面风速3种因素对装置换热量、温度效率和性能系数的影响，得出质量流量、换热面积和迎面风速的最优值。结果表明，夏季工况下，质量流量250 kg·h-1，换热面积58.0 m2，迎面风速1.8 m·s-1时，装置的换热量为4.09 kW，性能系数为9.26；冬季工况下，质量流量300 kg·h-1，换热面积58.0 m2，迎面风速1.8 m·s-1时，装置的换热量为6.63 kW，性能系数为14.20。

Abstract

A pump-driven heat pipe loop device was proposed for recycling energy from exhaust air and reducing energy consumption of processing fresh air in air-conditioning systems of public buildings. An experimental setup was built to investigate performances of such device under summer and winter working conditions. Through the study on effect of mass flow rate

heat exchange area and headwind velocity to heat transfer rate

temperature efficiency and coefficient of performance (COP)

the optimum mass flow rate

heat exchange area and headwind velocity were obtained. Under summer working condition

the device had achieved the heat transfer rate of 4.09 kW and the COP of 9.26 at the mass flow rate of 250 kg·h-1

the heat exchange area of 58.0 m2 and the headwind velocity of 1.8 m·s-1. Under winter working condition

the device had achieved the heat transfer rate of 6.63 kW and the COP of 14.20 at the mass flow rate of 300 kg·h-1

the heat exchange area of 58.0 m2 and the headwind velocity of 1.8 m·s-1.
