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.

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.

Exhaust gas flow control system for a metal hydride air conditioning unit

A system for distribution of hydrogen gas in a metal hydride reactor is disclosed. The system comprises a hydrogen distribution conduit positioned within a metal tube so as to define an annular space between the hydrogen distribution conduit and the outer metal tube. The hydrogen distribution conduit provides a flow passage for the hydrogen gas. A metal sponge matrix containing hydrogen-storing metal powder or hydrogen-storing alloy powder is filled in the annular space. The system provides a more uniform distribution of hydrogen across the particles of the hydrogen-storing metal/alloy powder, provides mechanical support to the hydrogen distribution conduit, improves the thermal conductivity of the powdered metal/alloy bed and reduces the size and production cost of the reactor.

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.

Control system for a metal hydride air conditioner and a method thereof

An air changeover system for a metal hydride heat pump is disclosed. The system includes metal hydride reactor modules aligned and separated by a partition; a shell containing the reactor modules, the shell is compartmentalized to define separate insulated chambers for each of the reactor modules; and a bearing assembly supporting the modules at a location about the partition, wherein the bearing assembly rotates said modules about an axis during the absorption and the desorption mode. The system reduces thermal inertia and pressure drop in the heat transfer medium while flowing through the heat pump, to enhance the performance and conserve energy.
