As molecular sieve zeolites have great ratio surface areas

a composite adsorbent was prepared by soaking zeolite in the solution of CaCl_2. Various 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. The experimental results show that the composite adsorbent has a good adsorption-desorption performance

and the maximum adsorbance is 46.93%. The COP is 0.25

and the SCP is 0.078w/g with the best performance composite adsorbent in the simulative refrigeration equipment

reaching the requirement of solar adsorption refrigeration.
