Performance Analysis on Temperature and Humidity Independent

Control Air-conditioning System

By Liu Xiaohua﹡，Xie Xiaoyun，Liu Shuanqiang and Jiang Yi

Abstract The operating strategy of the temperature and humidity independent control (THIC) air-conditioning system is proposed in present study. Processed outdoor air is used to remove the entire latent load and control indoor humidity level and also improve indoor air quality. Cooling source with relative high temperature is used to remove the sensible load and control indoor temperature. The performances of the main components of the THIC system, including indoor terminal devices, outdoor air handler and high temperature chiller, are discussed in detail. The THIC system has large energy saving potential compared with conventional air-conditioning system..

0引言

目前空调方式均通过空气冷却器同时对空气进行冷却和冷凝除湿，生产低温干燥的送风，实现排热排湿的目的。这种热湿联合处理的空调方式存在如下问题：（1）热湿联合处理所造成的能源浪费。排除余湿要求冷源温度低于室内空气的露点温度，而排除余热仅要求冷源温度低于室温。占总负荷一半以上的显热负荷本可以采用高温冷源带走，却与除湿一起共用7℃的低温冷源进行处理，造成能量利用品位上的浪费。而且，经过冷凝除湿后的空气虽
