Abstract
A heat pump that includes organic hydride (12) and metal hydride (2) systems cools a conditioned space (6) by transferring heat from the conditioned space to a metal hydride bed (4), thereby decomposing a metal hydride in the bed to form H.sub.2. The H.sub.2 flows to a vapor space (14) in the liquid hydride system (12) and reacts with a dehydrogenation product at a catalytic surface (32) in the vapor space to form an organic hydride and an exothermic heat of reaction. The heat pump also may be used to upgrade waste heat by transferring heat from a relatively low temperature heat source to decompose the metal hydride. The exothermic heat of reaction may then be removed from the vapor space and used for space heating. In both embodiments, the metal hydride bed (4) may be regenerated by supplying an endothermic heat of reaction to the catalytic surface (32), thereby dehydrogenating the organic hydride to form H.sub.2. The H.sub.2 flows to the metal hydride bed (4) and reacts with the metal hydride bed to regenerate the metal hydride. Alternately, the metal hydride bed (4) may be regenerated by flowing a liquid mixture that includes the organic hydride into a reaction zone (38) having a dehydrogenation catalyst (42) and supplying an endothermic heat of reaction to the reaction zone, thereby dehydrogenating the organic hydride to form H.sub.2. As before, the H.sub.2 flows to the metal hydride bed (4) where it regenerates the metal hydride.
