Abstract
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.
