A method and device are provided for increasing the temperature of heat. By supplying heat at a temperature T2 to a solid adsorbent, a working fluid is desorbed from this adsorbent at a relatively high pressure. The evolving gaseous working fluid is transformed to a liquid phase at a temperature T1′(T1′T2) while liberating heat. The working fluid is then transformed to the gaseous phase at a lower temperature T0 and a lower pressure p0 while heat is supplied. The generated gaseous working fluid is absorbed in a second adsorber/generator in a solid adsorbent. The absorber/generators periodically change between the adsorption and desorption phase and are operated in opposite phases. Before an interchange of the function of the two adsorber/generators, an internal heat exchange is carried out. The internal heat exchange includes a pressure equalization step with a subsequent heat transfer by a heat transfer loop. The use of an absorbent fluid leads to the resorption system which facilitates an optimization of the pressure levels used in the system.

A method of increasing the temperature of heat using a working fluid which is desorbed at a working fluid pressure p1 from a solid adsorbent contained in at least one adsorber/generator while supplying heat at a high temperature T2, where said working fluid is transformed from the vapor to a liquid

A method of increasing the temperature of heat using a working fluid which is desorbed at a working fluid pressure p1 from a solid adsorbent contained in at least one adsorber/generator while supplying heat at a high temperature T2, where said working fluid is transformed from the vapor to a liquid phase at an intermediate temperature T1 while liberating heat, where the liquid phase of said working fluid is transformed to a gaseous phase at low working fluid pressure p0 while taking up heat at a low temperature T0, where said gaseous working fluid is adsorbed and liberates heat in at least one further adsorber/generator containing said solid adsorbent, and where the process is continued by alternately desorbing and adsorbing in the two or more adsorber/generators, comprising; an internal heat exchange step used before changing from the adsorption to the desorption phase in the adsorber/generators which includes first a pressure equalization steip between at least one of the adsorber/generators at a higfher working fluid pressure and temperature and one or more other adsorber/generators being at a lower working fluid pressure and temperature and subsequently a heat transfer step from at least one of the adsorber/generators being at higher temperature with higher working fluid concentration to at least one of the adsorber/generators being at a lower temperature at a lower working fluid concentration.
