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.
