Envisaged is a regeneration system for a metal hydride heat pump of a damper type. The system comprises a plurality of reactor assembly modules configured to act as a heat pump, an ambient air inlet and a fluid recirculation circuit. The plurality of reactor assembly modules includes first, second, third and fourth metal hydride reactor assembly modules. The fluid recirculation circuit comprises a mixer, a fluid stream switching means, a flow regulating means and an exhaust outlet. The mixer is adapted to mix a portion of a recirculation stream received from the exhaust outlet and the exhaust gas stream to provide a resultant stream. The fluid stream switching means is coupled to the mixer and is adapted to switch flow of the resultant stream as received from the mixer and the ambient air stream in a cyclic manner in a series of half-cycles of operation.
