Patent ID: 7100398

Claim:
A method for producing cold and/or heat at a given place using one or a plurality of thermal energy sources comprising a succession of reversible processes between a gas and a liquid or a solid, which: is put into practice in an installation which comprises an HP assembly comprising reactors R 1 and R′ 1 , an LP assembly comprising reactors R 3 and R′ 3 , and possibly an IP assembly comprising reactors R 2 and R′ 2 , in which installation: each reactor R i is the seat of a reversible sorption alternatively producing and consuming the gas G i , each reactor R′ i is the seat of a reversible process alternatively producing and consuming the gas G i , the respective sorbents and gases in the reactors are selected so that, at a given pressure: the sorption equilibrium temperature in the reactor R i of an assembly is higher than the equilibrium temperature of the reversible process in the reactor R′ i of the same assembly, the sorption equilibrium temperature in the reactor R 1 is lower than that in R 3 , and, if applicable, the sorption equilibrium temperature in R 2 is between the equilibrium temperatures in R 1 and R 3 , the reactors R i and R′ i of an assembly are equipped with means for exchanging the gas G i , the reactors R i are equipped with means for exchanging heat with each other, the reactors are isolated from atmospheric pressure, and in which the thermal energy sources necessary for the operation of the installation supply the reactors R′ i .
