摘要(Abstract):
太阳能液体除湿空调系统是一种利用太阳能等低品位热源的节能空调系统,集热器集热性能和溶液化学蓄能特性是影响太阳能利用的重要因素。本文中再生器采用逆流式填料塔,氯化锂作为除湿剂,以真空管集热器作为集热源,实验分析了不同再生温度时,真空管集热器集热瞬时效率和化学蓄能特性。实验结果表明:真空管集热器瞬时效率呈凹形;较高的溶液再生温度有利于太阳能利用率和溶液化学蓄能能力的提高,再生溶液温度一般为6080℃。
Solar liquid desiccant air conditioning system is a kind of energy-saving air-conditioning system which uses a low-grade heat source,such as solar energy.Collector performance and storage of chemical solution play an important part in the use of solar energy.In this paper,the regenerator is a counter-flow packed tower,lithium chloride is taken as a dehumidifier,and vacuum tube collector is taken as a heat source.Experiments of instantaneous efficiency of vacuum tube collector and chemical storage characteristics are conducted under different regeneration temperature.The experimental results show: the instantaneous efficiency of vacuum tube collector is concave;high solution temperature can improve the ability of solar energy utilization and storage of chemical solution,reasonable regeneration temperature is generally 6080℃。
