摘要： The present invention relates to a cooling/heating method comprising the application and removal of a pressurising gas on a hybrid organic-inorganic porous material (MOF) whereby a breathing transition is produced, in which a change in volume in the structure of the compound occurs when its pores open/close, together with adsorption/desorption of a gas after applying and removing a pressurising gas on the compound; breathing which occurs at temperatures close to ambient temperature (from -20°C to 60°C) and at low pressures (from 10-5 bar up to 50 bar) and with great isothermal entropy changes (> 100 J K-1 kg-1). The invention also relates to a cooling/heating device comprising the hybrid materials defined above.

摘要： 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 ABX 3 (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% 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.
