摘　　要：图书馆阅览室一般人员较多,热湿负荷较大。其冷冻除湿辐射空调系统的设计,应以控制辐射板不结露、能耗低、舒适度最佳为目标。为此,以人体平均舒适度指标作为主要依据,确定了图书馆阅览室室内的设计温湿度。同时,为了降低能耗,应合理搭配除湿机组和辐射系统负荷。并探讨了用准热湿比线逼近法进行系统的除湿机组和辐射板冷负荷设计的辅助计算。经过逼近计算,可以得到比较准确的设计参数,并对某图书馆阅览室的设计实例进行分析,证明了该方法的有效性。Library reading room is a crowded building with large thermal and moisture load. Design of freezing dehumidification and radiant air-conditioning system for the reading room should achieve the target of non-dewfall condi- tion of the radiant panels, low energy consumption and optimal comfort. For this purpose, the indoor design temperature and humidity of the room were figured out mostly according to predicted mean vote. Meanwhile, in order to lower the energy consumption, air-conditioning load should be rationally allocated between dehumidifier unit and radiant panels. And a method of calculation aided by quasi thermal- humidity ratio line approximation was discussed. Through the approxi- mation calculation, considerable accurate design parameters can be obtained. By an analysis on a design example of a library reading room, the efficiency of the method was verified.
