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.

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.

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 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.

An air-conditioning system includes first and second PCM vessels, a heat recovery circuit, and a conduit and valve system. The heat recover circuit includes a third PCM vessel. The conduit and valve system operably couples i.) a first heat exchanger to the first PCM vessel and a radiator, ii.) a second heat exchanger to a core and the second PCM vessel, and iii.) the heat recovery circuit to the first heat exchanger.

An adsorption system can be used as part of a climate control system in a vehicle or in any other space requiring heating or cooling. The adsorbent system can include an enclosure, a plurality of layers arranged in a stack inside the enclosure, and a vapor channel inside the enclosure.

A cooling system for a vehicle cab where the vehicle has an internal combustion engine is provided. The system comprises a cooling chamber having an ambient air intake, and first and second pairs of sorption vessels. Each pair of sorption vessels comprises a first sorption vessel containing a sorption solution which is located in the cooling chamber and is in fluid communication with a second sorption vessel located outside the cooling chamber. The system further comprises first and second cooling circuits, each circuit containing a coolant and being in heat exchange contact with a respective one of the second sorption vessels. A first control valve selectively directs coolant from the first or the second cooling circuit towards the cab. An exhaust passage conveys exhaust gases away from the engine, and the exhaust passage has at least one exhaust aperture in communication with the cooling chamber. A moveable flap is located within the cooling chamber so as to divide the cooling chamber into a first chamber portion containing one of the first sorption vessels, and a second chamber portion containing the other of the first sorption vessels. The moveable flap is moveable between: a first position in which exhaust gas flows from the at least one exhaust aperture through the first chamber portion whilst ambient air flows from the air intake through the second chamber portion, and a second position in which exhaust gas flows from the at least one exhaust aperture through the second chamber portion whilst ambient air flows from the air intake through the first chamber portion.

Technologies are described herein for cooling systems. In some aspects, a cooling system is configured to enter into a storage configuration or a wintenzation configuration. In the wintenzation configuration, refrigerant used in the cooling system is stored in an adsorbent in an adsorbent chamber.

An exhaust gas flow control system disclosed relates to the field of mechanical engineering. The system reduces exhaust gas back pressure exerted on an internal combustion engine and prevents excessive heat loss in a radiator. The system comprises a flow regulator connected to an outlet of a silencer and configured to selectively direct the flow of exhaust gases to a metal hydride heat pump and/or a tailpipe. The flow of exhaust gases is directed towards the metal hydride heat pump in case of increased cooling requirement in the vehicle, and to the tailpipe in case of no cooling requirement or maintenance of the metal hydride heat pump. In case of reduced cooling requirement, partial flow of exhaust gases is directed to the metal hydride heat pump and the remaining to the tailpipe. A diverter is configured within the flow regulator to selectively direct the flow of exhaust gases.
