Heat transfer method
A method of heat transfer by means of a composition containing hydrochlorofluoroolefins. A heat transfer method including, successively, a step of evaporation of a coolant fluid, a compression step, a step of condensation of said fluid at a temperature of greater than or equal to 70° C. and a step of expansion of said fluid, characterized in that that coolant fluid includes at least one hydrochlorofluoroolefin.
1. A heat transfer process using a compression system comprising successively a step of evaporation of a refrigerant fluid, a step of compression of said refrigerant fluid, a step of condensation of said refrigerant fluid at a temperature greater than or equal to 110° C. and a step of expansion of said refrigerant fluid, wherein the refrigerant comprises at least 10% by weight of trans-1-chloro-3,3,3-trifluoropropene and at least 10% by weight a fluoroalkene.
2. The process as claimed in claim 1 , wherein the temperature is between 110 and 140° C.
