PROCESS AND DEVICE OF REFRIGERATION INDUCED BY AN EXTERNAL STIMULUS ON A CALORIC ORGANIC-INORGANIC- HYBRID MATERIAL
US2020332167
Process of refrigeration induced by an external stimulus comprising the application of an external stimulus selected among hydrostatic pressure, uniaxial pressure, electric field and illumination with light, to an organic-inorganic hybrid material of crystalline structure with hexagonal packing, of formula ABX3 (I), where A is a given monovalent organic cation or a given mixture of monovalent organic cations or a given mixture of monovalent organic cations and monovalent inorganic cations, B is a given divalent metal cation, a given mixture of divalent metal cations, or a given 50/50 percent atomic mixture of a monovalent cation and a trivalent cation, and X is a halide anion or a mixture thereof. A device with cooling capacity induced by an external stimulus, comprising the above organic-inorganic hybrid material.
This technology enables a change in the refrigeration, by the usage of new barocaloric materials, which are able to perform avoiding the utilisation of the gases currently used for the production of refrigeration devices and appliances. The potential impact of this technology is related to the reduction of the emissions of greenhouse effect gases.
The research group is currently involved in a round of contacts with Industry, pursuing the exploration of different options for the exploitation of this technology. The main objective is identifying companies interested in the technological implementation of our solid materials in cooling and/or heating commercial systems.
