Abstract: A method and installation is described for producing cold and/or heat, in a place where the latter are to be used, from one or more heat energy sources. The method is carried out in an installation comprising two or three assemblies of two reactors in which reversible phenomena involving a gas take place, said phenomena being exothermic in the sense of synthesis and endothermic in the sense of decomposition. The energy for the operation of the installation is supplied by a low temperature reactor of one or two assemblies. The installation is suitable for the remote production of cold or heat by means of the transport of gas at ambient temperature.
