A vehicle oxygen generating system includes a heat source, a power source, a vehicle air handling assembly of a vehicle air conditioning system, an H.sub.2O source and an electrochemical oxygen producing device. The oxygen producing device is connected to the H.sub.2O source receiving H.sub.2O therefrom. The oxygen producing device uses heat from the heat source and electricity from the power source to produce H.sub.2 and O.sub.2 from H.sub.2O. The O.sub.2 produced by the oxygen producing device is directed to the vehicle air handling assembly and moved into a passenger compartment of a vehicle.

A vehicular heat management system includes a heat pump cycle capable of heating a heat-exchanging-object fluid by using exhaust heat of an in-vehicle device as a heat source that radiates heat during operation, and an exhaust-heat refrigerant circuit that releases the exhaust heat to outside air through an exhaust-heat refrigerant. The heat pump cycle includes a recovery heat exchange portion that performs heat exchange between a heated air heated by the exhaust heat and a cycle refrigerant circulating in the heat pump cycle. The exhaust-heat refrigerant circuit includes an exhaust-heat exchange portion that performs heat exchange between the heated air and the exhaust-heat refrigerant. The recovery heat exchange portion and the exhaust-heat exchange portion are integrally formed as a combined heat exchanger capable of transferring heat between the cycle refrigerant and the exhaust-heat refrigerant.

The oven for the transport of food, installable in particular on motorcycles or the like, comprises a container securable to a motorcycle and having an inner chamber for the housing of food, an heating heat exchanger associated with the container and adapted to heat the air in the inner chamber, in which the heating heat exchanger has an inlet duct connectable to a scavenging system of the exhaust gases of the motorcycle and an outlet duct of the exhaust gases, and a dehumidifying heat exchanger associated with the container and adapted to dehumidify the air in the inner chamber, in which the dehumidifying heat exchanger comprises a cooling portion adapted to be hit by an air flow external to the container during the transit of the motorcycle, and a dehumidification portion positioned internally to the container and adapted to condense the water vapor present in the inner chamber.

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.

A vehicle climate control system includes a heat exchanger to heat ambient air using engine waste heat, and a plurality of positive temperature coefficient (PTC) heating elements to heat air passed through the heat exchanger. The vehicle also includes a controller programmed to, while the vehicle is driven without engine propulsion, issue a command to sequentially de-energize the PTC heating elements before an upcoming engine activation. The sequential de-energization of the PTC heating elements is performed according to a schedule that is based upon a power surge dissipation time.
