| 摘要 |
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. |

1. A heat transfer process for a compression system comprising at least one stage, said process comprising successively:
evaporating a refrigerant fluid; compressing the evaporated fluid; condensing the fluid at a temperature ranging from 70 to 140° C.; and expanding the fluid; wherein the refrigerant fluid consists of:
60 to 95 wt % of 1,1,1,3,3-pentafluoropropane and5 to 40 wt % of at least one hydrocarbon selected from the group consisting of n-pentane or isopentane. |
