A process and a system are disclosed for sorption heating and cooling which comprise at least 2 sorption zones. Each sorption zone comprises a heat transfer zone and an adsorption zone containing a sorbent such that the heat transfer zone is in intimate thermal contact with the adsorption zone to permit an essentially uniform temperature lengthwise through the sorption zone and thereby employ essentially all of the sorbent in the process at all times. The process comprises passing heat transfer streams such as a hot stream, a cold stream, and a recirculation stream through the heat transfer zone and routing a refrigerant through the adsorption zone of each sorption zone to affect a desorption stroke, an intermediate stroke and an adsorption stroke in the adsorption zone. Rotary and multi-port valves are employed to circulate the refrigerant and the heat transfer streams. The resulting sorption cooling process achieves a significantly higher coefficient of performance than the prior art.

[ We claim:] [1.] A process for sorption heating and cooling comprising the following steps:a. supplying a first hot stream to a first sorption zone of at least 2 sorption zones, each sorption zone comprising a heat transfer zone and a separate adsorption zone, said adsorption zone containing a sorbent, said heat transfer zone being in intimate indirect thermal contact with said adsorption zone to permit an essentially uniform temperature throughout said sorption zone to desorb a refrigerant vapor from the adsorption zone of said first sorption zone at an upper pressure and provide a hot exit stream from the heat transfer zone of said first sorption zone;b. passing the refrigerant vapor stream to a cooler and condenser zone to provide a condensate stream, reducing the pressure of the condensate stream to a lower pressure to provide a reduced pressure condensate, and passing the reduced pressure condensate to an evaporator zone to provide a revaporized refrigerant stream;c. passing a cold stream to the heat transfer zone of a second sorption zone and recovering a cold exit stream, and simultaneously conducting the revaporized refrigerant stream to the adsorption zone of said second sorption zone to adsorb the revaporized refrigerant;d. simultaneously terminating the passing of refrigerant vapor from said first sorption zone, terminating the passing of said hot stream to the heat transfer zone of said first sorption zone, terminating the passing of the cold stream to the second sorption zone, and passing a recirculation stream between the heat transfer zone of the first sorption zone and the heat transfer zone of the second sorption zone; ande. repeating the above steps (a) through (d) to provide a sorption cooling or heating cycle wherein said first sorption zone and second sorption zone alternately undergo a desorption stroke in step (a), an adsorption stroke in step (c), and an intermediate stroke in step (d) between alternate adsorption and desorption strokes.
