Study on Thermal Conductivities of Composite Adsorbents for Adsorption Refrigeration

Abstract:

Twenty-four Cacl₂/ENG molded composite adsorbents specimen were successfully prepared by aqueous solution and squeezing method. The thermal conductivities of the samples were tested by nanoflash LFA447. The experiment results show that: the thermal conductivity perpendicular to the direction of compression is over 1.2 times higher than that parallel to the direction of compression, which prove that the thermal conductivity is anisotropic. Within a certain range, the thermal conductivity is enhanced with increasing density and decreasing mass ratio. Under mass ratio is 2:1 and density rise from 600 kg/m3 to 700 kg/m3, thermal conductivity increase fastest. Density and mass ratio has coupling effect on the thermal conductivity of Cacl₂/ENG molded composite adsorbents.
