Porous adsorbents like zeolite andactivated carbon can adsorb gases evaporated from the adsorbate (wateror methanol, etc.) giving the cooling effect.  Upon being heated, the gas-saturated adsorbent bed will give off the gases which are then to becondensed.  This forms the adsorption refrigeration cycle.  The only problemis that the COP is very low (0.2 -0.6).
