Preparation of Composite Adsorbent for Adsorption Refrigeration by Soaking in Solution

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.
