Adsorption properties of activated charcoal for gel refrigeration units

Abstract

621.575:661.183.2.The operation of adsorption-type gel refrigeration units makes use of the physical process of adsorption -the condensation of molecules of a vaporous coolant on the solid surface of an adsorbent. During cooling, the vapors of the coolant condense in the pores of the adsorbent. This process is reversible, and when heat energy is supplied, the coolant is desorbed from the surface of the adsorbent.Activated charcoal is used as the adsorbent in gel refrigeration units. Thus, study of the adsorption capacity of activated charcoal is important for improving the efficiency of such units.
