Patent ID: 8511111

Claim:
An adsorber unit for an adsorption heat pump, comprising: a thermally insulated outer shell with a first end and a second end; a first and second thermally insulated plenum having the first plenum attached to the first end of the outer shell and the second plenum attached to the second end of the outer shell, wherein each plenum has at least one opening; a plurality of thermally conductive tubes aligned longitudinally inside the shell, each tube having an outside surface, wherein each tube comprises a plurality of projections extending from the outside surface of the tube and projecting outwardly therefrom, wherein each tube has a first and second ends; and wherein the first end of each tube is attached to the first plenum, and the second end of the tube is attached to the second plenum; at least one solid absorbent inside the shell surrounding the tubes; and at least one refrigerant capable of being adsorbed and desorbed by the adsorbent, inside the outer shell; wherein the outer shell, the first and second plenums, and the outside surfaces of the tubes form a closed system for containment of the absorbent and the refrigerant.
