ABSTRACT:
An integral adsorbent-heat exchanger apparatus for use in ammonia refrigerant heat pump systems. The apparatus has a finned tube heat exchange member. A bonded, pyrolyzed activated carbon adsorbent matrix, formed from a mixture of activated carbon particles and resol bonder, is tightly adjoined to the fins and the tube to form an integral apparatus. The integral apparatus is capable of withstanding repetitive adsorption and desorption cycles without the matrix becoming unbonded and without the matrix becoming unadjoined from the fins and tube. The apparatus permits very high rates of adsorption and desorption of refrigerant and very high rates of heat transfer between the refrigerant and the heat transfer fluid.
