摘要

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。

Abstract

Combined adsorption refrigeration and seawater desalination (ARSD) system is an emerging way to produce refrigeration and fresh water simultaneously. Focusing on several aspects that were not discussed in previous ARSD studies

the performance of refrigeration and water production and the energy benefit of two-bed ARSD under different conditions were studied using pure silica gel and composite CaCl2-in-silica gel as adsorbent. The results show that

comparing with separate refrigeration-only and water-only systems

the energy saving rate of cogenerated ARSD is significant

typically at 9.9%—26.2% and 22.4%—35.4% for the two adsorbents. The effects of the main parameters on cooling and water production and energy saving of the system are consistent

and concretely

higher evaporation temperature and peak desorption temperature

and lower condensation temperature and bottom adsorption temperature

are more favorable. Composite adsorbents are good for the performance of ARSD

but further study is needed to clarify the stability of composite adsorbents and the influence of the salt component on fresh water quality. Increasing water recovery rate leads to decreased performance of ARSD system. The decrease rate is marginal when the recovery rate is lower than 70%.
