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0.61kg·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192W·kg-1。
The adsorption performance of barium chloride-expanded graphite solidification composite adsorbent was tested, and the performance of solar adsorption air conditioning system using the adsorbent was analyzed. Experimental results show that the curing compound technology is conducive to improve the heat and mass transfer performance of the adsorbent, the experimental adsorbent cyclic adsorption capacity up to 0.61kg · kg-1; the same time, the heating fluid temperature, cooling temperature, evaporation temperature and reaction constraints Pressure on the performance of the adsorbent has varying degrees of impact. For the solar air-conditioning system using the composite adsorbent, at both the heating temperature of 80 ° C, the cooling temperature of 30 ° C and the evaporation temperatures of 5, 10 and 15 ° C, the COP and SCP of the system both increase with the increase of the evaporation temperature. 15 ℃, respectively, up to 0.5 and 192W · kg-1.
