摘　　要：为了解决湿热地区夏季温室的降温问题,提出了利用CaCl2溶液除湿降温系统对温室进行降温的方法。在CaCl2溶液除湿降温系统运行条件下,确定了以喷淋室出口空气相对湿度为试验指标,分析了进口空气流量、除湿剂流量、除湿剂浓度和温度、进口空气温度和湿度等因子对试验指标的影响。通过影响因子的单因素试验和多因素正交试验,得出了系统运行时影响除湿效果的显著因素是除湿剂浓度和温度、进口空气温度和湿度。利用回归分析建立了CaCl2溶液喷淋除湿的数学模型,并通过试验验证了该模型的最大相对误差小于5%。为中国南方高温高湿的温室夏季降温提供参考。In order to solve the cooling problem for greenhouse in the humid and hot area in summer, the liquid dehumidifying and cooling system with CaCl2 liquid is put forward in this article. Under the condition of operating the system, the relative air humidity around the sprinkling chamber outlet is determined as the experimental target and the factors affecting on the experimental indexes are analyzed, such as inlet air flow, liquid desiccant flow concentration and temperature, inlet air temperature and humidity and so on. Through the single factor experiment and multi--factor orthogonal experiment, the significant factors influencing dehumidifying effect are found out to be desiccant concentration and temperature, inlet air temperature and humidity when the system was operating. And the mathematical model of spraying and dehumidifying with CaCl2 is established and verified by regression analysis, and the maximum relative error of the model is proved to be less than 5 % . Therefore, this article provides a reference for greenhouse cooling under high temperature and high humidity condition in summer of South China.
