Patent number: 8327660Abstract: The invention relates to a thermochemical device and to a method for producing refrigeration at very low temperature. The device produces refrigeration at a temperature Tf<?20° C., from an available heat source at a temperature Th of 60-80° C. and a heat sink at the ambient temperature To of 10° C.-25° C. It comprises two coupled dipoles, operating in phase opposition. The thermochemical phenomena in one of the dipoles are such that this dipole may produce refrigeration at Tf with a heat sink at the ambient temperature To. The thermochemical phenomena in the other dipole are such that this dipole may be regenerated from the heat source Th and a heat sink at the temperature To.Type: GrantFiled: November 4, 2005Date of Patent: December 11, 2012Assignee: Centre National de la Recherche ScientifiqueInventors: Driss Stitou, Nathalie Mazet, Bernard Spinner, Caroline Spinner Brossard, legal representative, Anne Christel Spinner Kohler, legal representative, Bruno Spinner, legal representative, Martin Spinner, legal representative, Camille Spinner, legal representative

Patent number: 7775066Abstract: The invention relates to refrigeration using a thermochemical system based on the coupling of two reversible physico-chemical phenomena between a gas and a solid or liquid sorbent, one at low temperature (the LT phenomenon) and the other at a higher temperature (the HT phenomenon). The LT phenomenon is a liquid/gas phase change of the fluid G or an absorption of the fluid G by a liquid sorbent. The HT phenomenon is a reversible sorption of the fluid G by a liquid or solid sorbent. The endothermic phase of the LT phenomenon takes place in a reactor thermally isolated from the ambient environment. The exothermic phase of the LT phenomenon takes place in a condenser in communication with the reactor in which the HT phenomenon takes place, the condensed fluid G then being transferred to the reactor in which the endothermic phase of the LT phenomenon takes place.Type: GrantFiled: March 12, 2004Date of Patent: August 17, 2010Assignee: Centre National de la Recherche ScientifiqueInventors: Driss Stitou, Olivier Bertrand, Bernard Spinner, Bruno Spinner, legal representative, Caroline Spinner Brossard, legal representative, Anne Christel Spinner Kohler, legal representative, Nathalie Mazet, legal representative, Martin Spinner, legal representative
