摘要
以分子筛为基材通过浸泡C aC l2和S rC l2溶液的方法制备复合吸附剂.在模拟制冷条件下,对以不同浓度溶液制备的复合吸附剂的吸附、解吸性能进行了测定,并将吸附解吸性能最好的复合吸附剂在自制的模拟制冷装置上进行了制冷实验.结果表明,复合吸附剂具有良好的吸附、解吸性能,最大吸附量达51.6%,解吸率可达69.3%,在模拟制冷装置上系统的制冷系数达0.25,单位吸附剂的制冷功率为0.072 W/g,符合太阳能吸附制冷的要求.
A composite adsorbent was prepared by soaking zeolite in the solution of CaCl2 and SrCl2. A series of adsorbents were prepared with various concentration solutions. These adsorbent adsorption-desorption performances were measured in the simulative conditions. The refrigerant experiment was made in the simulative refrigeration equipment with the best performance composite adsorbent. Experimental results show that the composite adsorbent has a good adsorption-desorption performance with the maximum adsorbance reaching 51.6% and the desorption reaching 69.3%. The coefficient of performance (COP) is 0.25, and the specific cooling power (SCP) is 0. 072 W/g with the best performance composite adsorbent in the simulative refrigeration equipment, reaching the requirement of solar adsorption refrigeration.
