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.
