摘要

研究中采用膨胀硫化石墨作为基质

研制了一种新型氯化钙复合吸附剂，研究中测试了氯化钙复合吸附剂的非平衡吸附性能。研究表明：当冷凝温度由25℃变化到35℃，蒸发温度由-10℃变化到15℃时，密度为400kg/m3、质量分数为80%的氯化钙复合吸附剂样品的吸附量变化范围是0.4015kg/kg~0.4585kg/kg，与采用膨胀石墨为基质的复合吸附剂相比，吸附量变化不大。实验中氯化钙/膨胀硫化石墨的吸附/解吸时间约为3300s，与采用普通膨胀石墨相比，循环时间缩短了33%。在冷凝温度为30℃条件下，密度为400kg/m3、质量分数为80%氯化钙复合吸附剂最大SCP(单位质量吸附剂制冷功率)为65.75 W/kg，与采用普通膨胀石墨相比，SCP提高了48%。

Abstract

A new type of consolidated composite adsorbent for CaCl2 is developed by the matrix of ENG-TSA(Expanded natural graphite treated by the sulphuric acid). Adsorption performance of consolidated composite CaCl2 was tested

and the results showed that for the sample with the density of 400kg/m3 and salt mass ratio of 80%

adsorption quantity ranges from 0.4015kg/kg to 0.4585kg/kg while the cooling temperature ranges from 25 to 35℃ and evaporating temperature ranges from -10 to 15℃

respectively. The cycle adsorption quantity of consolidated CaCl2 with ENG-TSA as matrix is similar with that of consolidated CaCl2 with ENG as matrix

whereas the addition of ENG-TSA can greatly reduce cycle time as well as improve the specific cooling performance per kilogram adsorbent(SCP).The cycle time for the composite adsorbent of CaCl2/ENG-TSA is around 3300 seconds

which is 33% reduced if compared with that for the adsorbent of CaCl2/ENG. When the condensing temperature is 30℃

the maximum SCP for the adsorbent of CaCl2/ENG-TSA is 65.75W/kg which is increased by 48% if compared with the adsorbent of CaCl2/ENG.
