 Performance study of new adsorbent for solid desiccant coolingQun Cui, Haijun Chen, Gang Tao and Huqing Yao Energy, 2005, vol. 30, issue 2, 273-279 Abstract: The properties of 13x, silica gel, DH-5 and DH-7 adsorbents proposed by authors in solid desiccant cooling system were investigated. The adsorption isotherms of adsorbents were obtained. Cooling capacity as functions of time had been determined in the experimental device, which accomplished the behavior of adsorbent desiccant cooling. The performance parameters such as adsorption capacity, air humidity, regeneration temperature and cooling capacity were discussed. The results show: (1) the properties of DH-5 and DH-7 adsorbents on desiccant cooling are superior to those of commonly used desiccant (i.e., silica gel and 13x molecular sieve); (2) the maximum adsorption capacity of water on DH-5 and DH-7 reaches 0.72 and 0.73 kg/kg, respectively; (3) the desiccant cooling capacity of DH-5 and DH-7 are 2.2 and 1.3 times that of silica gel and 13x, respectively, after 100 °C regeneration; (4) the cooling capacity per mass unit of DH-5 is 1.9 times larger than that of 13x; (5) DH-5 and DH-7 are suitable for the desiccant cooling cycle, which is operated by low-temperature or low-grade waste heat.
