Abstract:

吸附式制冷-海水淡化(ARSD)复合系统是一种新型联产系统。针对目前ARSD研究的某些不足之处,以硅胶和硅胶-CaCl2为吸附剂,研究了不同条件下双床ARSD的制冷、制水性能和节能性能,结果表明:与单产系统相比,联产系统节能效果显著,在通常参数条件下,两种吸附剂系统的节能率分别为9.9%~26.2%、22.4%~35.4%;各主要参数对制冷、制水、节能率的影响规律是一致的,即提高蒸发温度和最高解吸温度、降低冷凝温度和最低吸附温度都对性能有利;使用复合吸附剂可获得更好的性能,但其稳定性和盐类成分对淡水水质的影响有待研究;ARSD系统性能随淡水回收率提高而降低,但在回收率低于70%范围内,降低幅度不大。
