摘要

测试了氯化钡-膨胀石墨固化复合吸附剂的吸附性能，并对采用该吸附剂的太阳能吸附式空调系统性能进行了分析。实验结果表明，固化复合技术有利于提高吸附剂的传热传质性能，实验中复合吸附剂循环吸附量可高达0.61 kg·kg-1;同时，加热流体温度、冷却温度、蒸发温度以及反应约束压力对吸附剂性能都有着不同程度的影响。对于采用该复合吸附剂的太阳能空调系统，在加热温度80℃，冷却温度30℃，蒸发温度分别为5、10、15℃时，系统COP 和SCP均随蒸发温度的升高而增大，在15℃时可分别高达0.5和192 W·kg-1。

Abstract

A consolidated composite sorbent made of barium chloride impregnated with expanded graphite powder was tested and the performance of a solar-powered sorption air-conditioning system using this kind of sorbent was analyzed.Experimental results showed that the heat and mass transfer were both improved by the consolidated composite sorbent.The consolidated composite sorbent could uptake 0.61 kg ammonia per kg reactive salt.Moreover，the sorption was influenced by the heating water temperature，cooling water temperature，evaporation temperature and constraint pressure.For a solar air-conditioning system using this kind of sorbent，coefficient of performance（COP）and specific cooling power（SCP）both increased with evaporation temperature raised from 5℃ to 15℃，at heating water temperature of 80℃ and cooling water temperature of 30℃.The values of COP and SCP reached 0.5 and 192 W·kg-1 respectively at evaporation temperature of 15℃.
