固体吸附制冷工质对的性能研究

选用水和乙醇作为吸附质，开发了性能优良的吸附剂NA和NB，在自制的吸附制冷模拟实验装置上，对NA－水和NB－乙醇等吸附工质对的吸附制冷性能进行了研究。结果表明：自制吸附剂NA对水的最大吸附量达到0.7kg/kg以上，吸附剂NB对乙醇的最大吸附量为0.68kg/kg,NA-水和NB－乙醇工质对有着较低的吸附热，NA－水工质对的制冷量可达992kJ/kg,NB-乙醇工质对的制一大约为活性碳－甲醇的2．4倍，是一种环境友好型，无公害的工质对。

Study of performance for Solid Adsorption refrigeration Working Pairs

Water and ethanol were selected as absorbates, absorbent NA and NB with good performance were developed by ourselves. On self - made simulated experimental device for absorption refrigeration, performance for absorption refrigeration of absorption working pairs, such as NA - water and NB - ethanol etc., were studied. The results show that the maximal absorptive capacity of absorbent NA on water reached more than 0.7 kg/kg, the maximal absorptive capacity of absorbent NB on ethanol reached 0.68 kg/kg; the absorption working pairs NA water and NB - ethanol have lower absorption heat; The cooling volume of NA - water can reach 922 kJ/kg, the cooling volume of NB - ethanol is about 2.4 times that of activated carbon - ethanol, and it is an environment friendly and no public hazard working pairs.
