Production of Very Low-Temperature Refrigeration in a Thermochemical Device

摘要

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. One of the dipoles may be regenerated from a heat source at the temperature Th and a heat sink at To, and produce refrigeration at the temperature Tf with a heat sink at a temperature below the ambient temperature To. The other dipole may be regenerated from a heat source at the temperature Th and a heat sink at the temperature To.
