摘　　要：为提高太阳能吸附制冷系统的集热性能 ,提出了采用真空集热管式吸附床的太阳能固体吸附制冷系统 ,并对选择吸收式和直接吸热式的真空集热制冷系统分别进行了理论分析与计算模拟。这两种系统均具有较高的制冷性能 ,前者宜以沸石 -水为制冷工质对 ,而后者则宜采用活性碳 -甲醇工质对。分析了工作参数对这两种真空集热型制冷系统的影响 ,并对系统结构进行了优化研究。An adsorption solar cooling system with evacuated tubes is developed to improve the system efficiency.Two types of evacuated tubes,with and without selective coating,are used to store the adsorbent and collect the solar energy.Theoretical simulation shows that such an evacuated tube adsorption cooling system with zeolite-water or active carbon-methanol working pair has a better performance than that with conventional plate adsorbent bed.The effects of the diameter of the evacuated tube,the heating time and the emissivity of the selective coating on the performance of the cooling system is studied,and the optimization design of the system is investigated.
