Abstract:
The invention relates to a heat transfer method that uses a composition containing from 60 to 95 wt % of 1,1,1,3,3-pentafluoropropane and from 5 to 40 wt % of at least one hydrocarbon selected from n-pentane, isopentane and cyclopentane. The invention more particularly relates to a heat transfer method that successively includes the step of evaporating a refrigerant fluid, a compression step, the step of condensing said fluid at a temperature higher than or equal to 35° C., and preferably between 70° C. and 140° C., and the step of expanding said fluid, characterized in that the refrigerant fluid includes from 60 to 95 wt % of 1,1,1,3,3-pentafluoropropane and from 5 to 40 wt % of at least one hydrocarbon selected from n-pentane, isopentane and cyclopentane.
