摘　　要：本文介绍了温湿度独立控制空调系统的工作原理,并重点介绍了湿度独立控制系统-溶液除湿空调方式。实验测量了溶液除湿空调系统的运行效果,溶液除湿空调系统的性能系数随着室内相对湿度的增加而降低。当使用75℃热水时,采用冷却水冷却的溶液除湿空调系统的夏季平均性能系数为0.93,采用排风蒸发冷却的溶液除湿空调系统的夏季平均性能系数为1.19。本文还给出温湿度独立控制空调系统的性能与常规空调系统在耗电量和运行能耗方面差异的分析方法,结果表明:采用溶液除湿空调方式的温湿度独立控制空调系统比常规空调系统节省约50%的耗电量,节省20～30%的运行费用。The operating principle of the temperature and humidity independent control （THIC） air-conditioning system is proposed in present study. The humidity control system using liquid desiccant is described in detail, and the performance is experimentally tested. The COP （coefficient of performance） of the liquid desiccant system decreases with increasing outdoor relative humidity ratio. The summer average COP of the liquid desiccant system which is cooled by cooling water and indoor exhaust air evaporative cooling is 0.93 and 1.19 respectively. The operating energy consumption is compared between the liquid desiccant based THIC system and the conventional air-conditioning system. The comparison results show that the THIC system saves about 50% power consumption and 20-30% operating cost, compared with the conventional air-conditioning system.
