| 摘要 |
The invention relates to a method of heat transfer by means of a vapor compression circuit containing a heat transfer fluid, said method including, consecutively, evaporating the heat transfer fluid, compressing the heat transfer fluid, condensing the heat transfer fluid to a temperature greater than or equal to 70° C, and decompressing the heat transfer fluid. In said method, the heat transfer fluid includes 1,1,1,3,3-pentafluorobutane and 1,1,1,3,3-pentafluoropropane, the compounding weight ratio of 1,1,1,3,3-pentafluorobutane in the fluid being no higher than 20%. The invention also relates to a heat transfer fluid suitable for implementing said method and to a facility that is also suitable for implementing said method. |
