Performance simulation of compound solar liquid desiccant air conditioning
摘要：
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。
Abstract：
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.
