摘要： Envisaged is an exhaust gas heat recovery system comprising a heat pump, a mixer and a flow regulating means. The heat pump is configured to pump heat from a refrigerant. The heat pump has an inlet and an outlet wherein the exhaust gas stream leaving the outlet is split into two streams: a stream rejected to atmosphere and a recirculating exhaust stream re-circulated back to the heat pump. The mixer is provided at the inlet of the heat pump to mix an inlet exhaust stream with the recirculating exhaust gas stream to get a resultant exhaust stream at an intermediate temperature of the two streams. The flow regulating means is adapted to compress the recirculating exhaust stream.

摘要： A control system as disclosed in the present disclosure relates to the field of metal hydride air conditioning systems in vehicles. The control system improves cooling capacity and the coefficient of performance of the metal hydride air conditioner. The control system comprises a plurality of sensors, a memory, a time counter, a controller, and at least one actuator. The controller takes into account the pre-set half cycle time as well as the temperature of the exhaust gases at the outlet of a HT or LT reactor for changing fluid flow, i.e. from hot/cold fluid to the fluid at ambient temperature or vice versa, entering the reactors of the metal hydride air conditioner.

摘要： 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 out let. 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.
