溶液除湿和太阳能再生技术,是解决高温高湿地区蒸发降温技术难题的关键.该文利用建立的太阳能再生溶液除湿实验台,实验测量研究了氯化钙(CaCl_2)和氯化锂(LiCl)混合盐溶液(物质的量比1:1)的密度与不同质量分数之间的关系;研究了进口空气的温度、湿度、流量,盐溶液的流量,溶液的质量分数、水汽压差等参数与除湿量之间的关系.结果表明:混合溶液的密度与其中的某一组分的溶液(CaCl_2)密度非常近似,两者有很好的线性关系;影响除湿量的关键因素是传热传质过程中混合盐溶液和空气的水汽压差的大小.根据Ertas的实验研究,论文得到了氯化钙(CaCl_2)和氯化锂(LiCl)混合溶液质量分数为20%～40%的溶液水汽压的计算公式,以及水汽压差和除湿量之间的关系式.该研究为禽畜舍、温室等设施除湿技术提供了新的研究思路.

The technology of liquid desiccant and solar regeneration, is the key technical problems of evaporative cooling in high temperature and humidity region. Through the experimental measurement, the relationship between the density and the different quality percentage of calcium chloride (CaCl_2) and chloride lithium (LiCl) mixture liquid (molar ratio of 1:1) was studied. Also the relationships between the import of air temperature, humidity, air flow, salt solution flow, the solution quality concentration, water vapor pressure difference and the dehumidification were studied. The conclusion is that density of the mixture is very approximate to that of the solution component (CaCl_2), and the important effect element of dehumidification is the differential pressure between the heat and mass transfer process in the air and solution. According to the experimental research of Ertas, the author got the vapor pressure calculation formula of the mixture calcium chloride (CaCl_2) and chloride lithium (LiCl) with quality percentage of 20%-40%, and the formula of the differential vapor pressure and the dehumidification. This research provides a new thinking for dehumidifying technology of greenhouse facilities and livestock and poultry houses.
