A method for heating a fluid or a body using a vapor compression circuit containing a heat-transfer fluid containing tetrafluoropropene, said method including, successively and cyclically, evaporation of the heat-transfer fluid, compression of the heat-transfer fluid, cooling of the heat-transfer fluid and expansion of the heat-transfer fluid, the heat-transfer fluid being in the supercritical state at the end of compression. Also, an installation suited to implementing this method. |
