Abstract:

Characteristics of 13x molecular sieve, silica gel and DH-5 and DH-7 prepared by authors, were investigated for the solid desiccant cooling system. The adsorption isotherms of DH-5 and DH-7 were experimentally determined. The performance parameters of adsorption capacity, air humidity, regeneration temperature and cooling volume were tested and discussed in detail. The results show that the properties of new adsorbents DH-5 and DH-7 on desiccant cooling are much better than those of common desiccants. The maximum adsorption volumes of water on DH-5 and DH-7 are 0.72 kg/kg and 0.73 kg/kg, respectively. The desiccant cooling volumes of DH-7and DH-5 are 2.2 and 1.3 times larger than those of silica gel and 13x(molecular sieve), respectively, after regeneration at 100 ℃. The cooling volume per mass unit of DH-5 is 1.9 times larger that of 13x.
