REGENERATION SYSTEM FOR A METAL HYDRIDE HEAT PUMP

摘要

A self-cleaning metal hydride heat recovery system comprising a thermally insulated housing partitioned into at least two thermally insulated chambers, each chamber enclosing a metal hydride reactor assembly containing a regenerating, high-temperature metal hydride alloy, an ambient air inlet adapted to receive an ambient air stream into the housing to be fed to at least one of the two thermally insulated chambers, a fluid recirculation circuit configured to recirculate an exhaust stream as received from an exhaust source, the fluid recirculation circuit comprises a mixer adapted to mix a portion of a recirculation stream and the exhaust stream to provide a resultant stream, fluid stream switching means coupled to the mixer and adapted to switch a flow of the resultant stream and the ambient air stream in a cyclic manner, flow regulating means provided downstream of the metal hydride reactor assemblies, and an exhaust outlet.
