Abstract: A series of compound adsorbents with zeolite as the main component were prepared, and the adsorption and desorption performance of these adsorbents were measured.To get the expected compound adsorbent, the filling densities and the forming characteristics of the compound adsorbent were tested.The study showed that the performance of compound adsorbent E was better than that of the original 13X zeolite.The filling densities decreased remarkably with the silica sol content between 0—7%.A solar cooling tube was made from the compound adsorbent E,its coefficient of performance (COP) was about 0.24—0.28.

摘要： 以13X沸石原粉为主要成分添加不同配比硅溶胶配制新型制冷复合吸附剂，采用热排空法对配制的复合吸附剂进行闭式吸附和脱附性能试验。用开放式吸附测量法对复合吸附剂的最大吸附量进行测试，同时测量各复合吸附剂填充密度以及整体成型性能与硅溶胶含量的变化。试验结果表明：复合吸附剂E的闭式吸附和脱附性能均优于13X沸石原粉；在封闭系统中复合吸附剂吸附速度远远高于在开放式系统；在硅溶胶含量0-7%时复合吸附剂的填充密度随添加的硅溶胶迅速下降。综合各性能参数，复合吸附剂E被选择应用于太阳能冷管，其制冷系数COP约为0.24-0.28。
