提出了一种热泵驱动的液体除湿独立湿度控制空调系统。该系统由液体除湿新风处理器和高温冷水系统组成。详细介绍了新风处理机的工作原理和整个系统。基于上海建筑科学研究院(SRIBS)生态建筑的现场安装系统，于2007年夏季进行了性能调查。测试结果表明：(1)室内温度和湿度都在规定的范围内；(2)高温冰箱的供水温度高于相应的室内空气露点温度，不会在风机盘管(FCU)表面形成冷凝水；(3)新风处理器和高温冰箱的平均性能系数(COP)分别为6.24和4.38，整个IHC系统的平均COP为5.28。
A liquid desiccant based independent humidity control (IHC) air-conditioning system driven by heat pumps is presented in this paper. The system consists of a liquid desiccant fresh air processor and a high-temperature chilled water system. The operating principles of the fresh air processor and the whole system are presented in detail. Based on the in situ system installed in an ecological building of Shanghai Research Institute of Building Sciences (SRIBS), a performance investigation was performed in summer, 2007. The measurement results show that (1) the indoor temperature and humidity both are in the specified range; (2) the supply water temperature of the high-temperature refrigerator is higher than the corresponding indoor air dew point temperature, so no condensed water would be formed on the fan-coil unit (FCU) surface; and (3) the average coefficients of performances (COPs) of the fresh air processor and the high-temperature refrigerator are 6.24 and 4.38, respectively, and the average COP of the whole IHC system is 5.28.
