摘　　要：对于一次回风再热式系统,利用冷凝热作为再热热源,保证相对湿度的同时,可节省再热能耗。提出利用空调冷却水回水再热调节送风参数,并以合肥某餐厅为例进行计算分析。结果表明:该系统与露点送风能耗相同,比常规再热送风节能6%~25%,水泵扬程不变,再热量能够保证。该方案具有一定的节能性、可行性,适用于相对湿度要求较高的空调场所。Using cooling water to reheat primary return air and regulate air supply parameters can ensure relative humidity as well as reduce reheat energy consumption. A restaurant in Hefei was analyzed. The results show that the head of the cooling water pump need not to be enlarged, and the energy consumption is the same as that of the dew point air supply. 6% ~25% energy saving can be achieved compared with the conventional reheat air supply system. The scheme has the potential for air-conditioned places with high relative humidity requirements.
