Performance simulation of compound solar liquid desiccant air conditioning

结合热湿地区的气候特点,设计了复合型太阳能溶液除湿空调系统,并通过数值模拟,分析了除湿器和再生器入口空气参数对系统性能的影响。结果表明,除湿器入口空气温、湿度从36℃和80%冷却减湿预处理到26℃和90%时,除湿器的体积可减小约63%,溶液循环量减小约58%;使用房间排风作为再生空气源,可明显提高溶液的再生效率和浓度,有效降低再生热源温度。

In accord with the climatic conditions in hot-humid areas,designs a compound solar liquid desiccant air conditioning system.By establishing a mathematical model,analyses the effects of inlet air parameters of dehumidifier and regenerator on system performance.The results indicate that when dehumidifier inlet air is pretreated from 36 ℃and 80%to 26 ℃ and 90% by cooling and dehumidifying preprocess,the dehumidifier＇s volume can be reduced by about 63%,and solution circulating amount about 58%,and that by taking indoor exhaust air as regeneration air,the regeneration efficiency and concentration of liquid can be improved,and the temperature of the regeneration heat source reduced effectively.
