Abstract:
An air conditioner for an automobile includes two pairs of hydrogen storage cells. Each cell includes a hydride-forming material, which absorbs hydrogen while generating heat, and releases hydrogen while absorbing heat. One pair of cells operates as an air conditioner, absorbing heat from the interior of the automobile and discharging heat to the outside. The other pair of cells, is regenerated by supplying heat from the engine exhaust to one of the cells, while allowing heat generated at the other cell of the pair to be discharged to the outside. After a given pair of cells has been regenerated, the cells are cooled to approach the temperature at which they will again operate as an air conditioner. A system of valves is arranged to provide four distinct stage. In Stage 1, the first cell pair is an air conditioner while the second cell pair is being regenerated. In Stage 2, the second cell pair is cooled. In Stage 3, the second cell pair is an air conditioner while the first cell pair is being regenerated. In Stage 4, the first cell pair is cooled. Cooling of the cell pairs reduces the parasitic cooling load which would otherwise reduce the efficiency of the apparatus. The cooling step includes the step of causing a heat transfer medium to circulate between the first cell of the first pair and the first cell of the second pair.

The other pair of cells is regenerated by supplying heat from the engine exhaust to one of the cells, while allowing heat generated at the other cell of the pair to be discharged to the outside. A system of valves is arranged such that one cell pair is always functioning as an air conditioner while the other cell pair is being regenerated.
Abstract:
A plurality of adsorption containers are provided which are separated into heater adsorber zones and condenser evaporator zones. The zones are successfully rotated through flow segments which form a passageway for heat carrier flows. The heater adsorption zones contain an adsorption substance from which an operating substance is extracted by adsorbing heat from a heat carrier flow and is again adsorbed by emitting heat to a further heat carrier flow. The operating substance condenses and evaporates by means of a heat exchange with further heat exchangers. The adsorption devices are suitable as cooling devices and heat pumps as well as heat transformers and heat exchangers.

Abstract:
An absorption heat pump device includes a heat exchange unit through which a heat exchange fluid flows, a rotor that includes a hollow rotary shaft member including a first internal flow path and discharges a solution in the first internal flow path by a centrifugal force, and an application member that moves with rotation of the rotor to apply the solution, which flows through the first internal flow path and is discharged, along a heat transfer surface of the heat exchange unit.
Abstract:
An adsorption based system is provided for the selective cooling and heating of a vehicle compartment using by-product water collected from a power generating unit of a vehicle. The system may include a fuel cell stack and an exhaust conduit configured to transfer an exhaust stream from the fuel cell stack. A water reservoir stores by-product water collected from the exhaust stream. The system may include a coolant loop configured to circulate a coolant fluid. A detachable adsorption subsystem is in thermal communication with the coolant loop and the exhaust conduit, and may include an evaporator and an adsorbent bed. The adsorption subsystem is configured to: vaporize water from the water reservoir using the evaporator; adsorb the vaporized water, thereby cooling a portion of the coolant fluid; regenerate the adsorbent bed using heat from the exhaust stream to release water vapor; and direct the water vapor into the exhaust conduit.
Abstract:
A method and device for cooling and/or heating media, preferably in a motor vehicle, the method in which at least one first heat source is cooled and at least one second heat sink is heated by a thermal management system. In a method in which the heating or cooling can occur on demand, heat and/or cold are shifted by the thermal management system in space and time to the heat sink and/or heat source, which is characterized by need.
