【 摘 要 】

In view of the problems existing in adsorption refrigeration based on low temperature geothermal water, the adsorbent with high mass transfer performance was prepared by carbonization activation method. The specific methods are as follows: firstly, Chinese fir sawdust is immersed in calcium chloride solution, then taken out and dried, and the mixture is carbonized and activated at high temperature to form a porous activated carbon/calcium chloride composite adsorbent, and then expanded graphite is added to enhance the thermal conductivity of the composite adsorbent.The results show that: The proportion of calcium chloride in the composite adsorbent can be significantly increased by carbonization activation method, which makes the composite adsorbent have abundant microporous structure and uniform element distribution. The thermal conductivity of the composite adsorbent can be improved by adding expanded graphite.
