Adsorption heat pump development at the Jet Propulsion Laboratory.

Author(s) : JONES J. A.

Summary

The paper explains the principle and operation of a cold-production system using gas adsorption on solids arranged in layers (wrapped active coal). Regeneration by heating restitutes the gas under pressure, which can be cooled down, condensed or expanded through the Joule-Thomson effect. All sorts of fluids can be utilized (hydrogen, oxygen and nitrogen, for cryogenic applications; R22, R134a, ammonia, etc., for common applications). A basic presentation is given of the combination of adsorbant layers, exchangers and the heat-carrying circuit for heating or cooling. Performance and possible improvements are evoked. The service life of the layers is long and there are almost no moving parts.
