摘要: 实验研究了超声雾化液体除湿空调系统的除湿效率,分析了氯化钙和氯化锂混合盐溶液的质量分数、液气比、气液反应时间等因素对除湿效率的影响.结果表明,在9种实验工况下,系统的除湿效率为18.1%~26.9%.随着混合盐溶液的质量分数从38%减小至35%,系统除湿效率逐渐降低;液气比是影响系统除湿效率的重要因素,当液气比由0.18增至0.84时,除湿效率提高约50%;增加气液反应时间能够有效改善除湿效率.另外,提高除湿效率会导致空气温升变大.

Abstract: The dehumidification efficiency of the ultrasound atomization dehumidifying system with liquid desiccant was studied experimentally. The effects of quality concentration of calcium chloride and lithium chloride mixture solution, liquidair ratio and air-liquid reaction time were analyzed according to the experimental data. It is found that the dehumidification efficiency of this system is 18.1%~26.9% under 9 groups of experimental conditions; the efficiency decreases when the salt quality concentration decreases from 38% to 35%; the liquidair ratio greatly affects the dehumidification efficiency, which increases 50% when the liquid-air ratio increases from 0.18 to 0.84; increasing the reaction time helps improve the efficiency. Moreover, the temperature of the processed air is raised when the efficiency increases.  

Key words: liquid desiccant, ultrasound, atomization, dehumidification efficiency
