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.

对自制吸附剂(DH-50, DH-70), 硅胶和13x的除湿制冷性能进行了实验研究.测定了DH-5和DH-7吸附剂的吸附等温线;对DH-5, DH-7, 硅胶和13x用于除湿制冷过程的动态特性进行了研究;讨论了吸附量、空气湿度、再生温度和单位质量吸附剂的制冷量对固体除湿过程的影响.结果表明:DH-5和DH-7的除湿制冷性能明显优于常规吸附剂(硅胶和13x).DH-5和DH-7吸附剂的最大平衡吸附量分别为0.72 kg/kg和0.73 kg/kg;在100 ℃条件下再生, DH-7吸附剂的除湿制冷量是硅胶
