溶液除湿系统除湿性能实验研究
Experimental study on dehumidification performance of liquid desiccant systems
摘要：
基于正交试验设计方法，对入口溶液质量分数、入口溶液温度、入口液气比、入口空气含湿量、入口空气温度这5个因素对出口空气含湿量的影响进行了实验研究。结果表明，除湿量受前4个因素的影响较显著，受入口空气温度影响较小；入口液气比较小时，除湿量随入口液气比的增大而增大，但当入口液气比大于1.5后，除湿量几乎不随入口液气比的增大而变化；对单位除湿量的影响程度由大到小为：入口空气含湿量、入口溶液质量分数、入口溶液温度、入口液气比、入口空气温度。
Abstract：
Through orthogonal experiment design, experimentally studies influences of mass fraction and temperature of inlet liquid, inlet liquid-air ratio, and humidity ratio and temperature of inlet air on the humidity ratio of outlet air. The results show that the first four factors affect significantly the dehumidifying capacity, and the effect of inlet air temperature is week; when the inlet liquid-air ratio value is smaller, the dehumidifying capacity increases along with the inlet liquid-air ratio; when the inlet liquid-air ratio is larger than 1.5, the dehumidifying capacity does almost not change along with the inlet liquid-air ratio; the sequencing of the five factors in the influence on unit dehumidifying capacity from large to small is the humidity ratio of inlet air, mass fraction of inlet liquid, temperature of inlet liquid, inlet liquid-air ratio and temperature of inlet air.
