摘要

测试了硅胶-水吸附制冷工质对的等量吸附线，且利用各类吸附方程对实验测量数据进行拟合以用于硅胶-水冷水机组的整体系统的数值模拟。实验还通过在纯硅胶颗粒中添加黏结剂或膨胀石墨形成混合吸附剂来提高传热性能。研究表明混合吸附剂（黏结剂的含量为1.1％）在解吸过程中前5min的解吸量相对于纯硅胶颗粒吸附剂提高了13.8％;解吸15min时，混合吸附剂的解吸量相对于纯吸附剂仅提高2.5％。表明混合吸附剂有利于缩短吸附循环周期。在添加剂质量分数相同的情况下，利用膨胀石墨作添加剂形成的混合吸附剂与通过浸泡于黏结剂溶液中形成的混合吸附剂的吸附性能相同，但有其各自的优缺点。

Abstract

Adsorption isosteres of the silica gel (SG) -water adsorption refrigeration working pairs were obtained.Several adsorption equations have been fitted to the experimental points in order to get the adsorption equation

which could be used for the simulation of the silica gel-water adsorpion chiller.Besides

two composite adsorbents were also developed to enhance the heat transfer.One is obtained by mixing expanded graphite and silica gel.The other is developed by adding a binder into silica gel.The results show that when the mass ratio of the binder in the composite adsorbent is 1.1%

the amount of the water desorbed is increased by 13.8% for first 5min; and it is increased by 2.5% for 15min.To conclude

the composite adsorbent can shorten the cycle time.The composite adsorbent with expanded graphite has the same performance as the composite adsorbent mixed with binder.And both of them have advantages and disadvantages.
