- Abstract:
- Water and ethanol were selected as refrigerants, 13x molecular sieve, silica gel, activated carbon and adsorbents NA and NB prepared by authors were selected as adsorbents, and the performance of adsorption working pairs in adsorption refrigeration system was studied. The adsorption isotherms of adsorbents(NA and NB)were obtained by high-vacuum gravimetric method. Desorption properties of adsorbents were analyzed and compared by thermal analysis method. The performance parameters of adsorption refrigeration of different adsorption working pairs were studied on experimental device of adsorption refrigeration cycle. The results show: (1) The maximum adsorption quantity of water on adsorbent NA arrives at 0.7 kg/kg, and the maximum adsorption quantity of ethanol on adsorbent NB is 0.68 kg/kg, which is 3 times that of ethanol on activated carbon; (2) The refrigeration volume of NA-water working pair is 922 kJ/kg, the refrigeration volume of NB-ethanol is 2.4 times that of activated carbon-methanol; (3) As friendly to environment and no public hazard adsorption working pair, NA-water and NB-ethanol can substitute for carbon-methanol in adsorption refrigeration using low-grade thermal energy.
- 对水、乙醇和13x分子筛、硅胶、活性炭以及自制吸附剂NA、NB组成的吸附工质对的制冷性能进行了研究.用高真空重量法测取了自制吸附剂NA和NB的吸附等温线;用热分析法对吸附剂的脱附性能进行了分析;在吸附制冷循环实验装置上研究了吸附工质对的制冷性能参数.结果表明:(1)自制吸附剂NA对水的最大吸附量高达0.7 kg/kg;自制吸附剂NB对乙醇的最大吸附量达0.68 kg/kg, 是活性炭对乙醇吸附量的3倍;(2) NA-水工质对的制冷量是922 kJ/kg, NB-乙醇工质对的制冷量是活性炭-甲醇的2.4倍;(3) NA-水和NB-乙醇是环境友好型、无公害的吸附工质对, 可替代活性炭-甲醇工质对用于以低温热源驱动的吸附制冷系统.
