摘要:
比较系统介绍了太阳能溶液除湿制冷系统国内外研究历史及现状.提出一种新型太阳能空气预处理溶液集热/再生流程,相对传统集热/再生器理论计算发现其溶液浓度差可提升90%,蓄能密度增加50%.从理论上构建了太阳能驱动溶液除湿与辐射供冷复合空调系统的工艺流程,并对填料塔除湿和再生器进行实验研究得到其传质系数的表达式.从热力学角度找出溶液除湿冷却系统理论再生效率和理论性能系数的表达式.当溶液浓度较低时,理论再生率可大于1.0; 当环境温度为35 ℃,热源温度由60 ℃升到100 ℃时,理论性能系数提高1.0.
Abstract:
The study history and actualities of solar liquid desiccant cooling systems are introduced systematically. A new solar air pretreatment collector/regenerator flow is put forward. Through theoretical calculation it is found that the solution concentration difference between outlet and inlet of the air pretreatment collector/regenerator increases 90% and the storage capacity increases 50% comparing with the traditional C/R(collector/regenerator). In theory the crafts are constructed on the compound air conditioning system including solar liquid desiccant and radiation cooling and the expressions of mass transfer coefficient on the packed bed dehumidifier and regenerator are gained by experiments. Through thermodynamics analysis, the expressions of theoretical regeneration efficiency and coefficient of performance(COP)are found. When the solution concentration is low, theoretical regeneration efficiency may be larger than 1.0 and when the temperature of heat source rises from 60 to 100 ℃, COP augments 1.0 with the surrounding temperature of 35 ℃.
