Abstract
The invention relates to a method for cooling or heating a fluid or a body by means of a vapour compression circuit containing a heat transfer fluid, said circuit being at least partially contained in an enclosure, and the relative humidity of the air in the enclosure being less than or equal to a threshold value H1 which is less than 50%, the flammability of the heat transfer fluid at relative humidity H1 being less than the flammability of the heat transfer fluid at 50% relative humidity.The invention also relates to a cooling or heating installation suited to the implementation of this method. The invention also relates to a method of protection against the risks of fire or explosion in an enclosure containing at least partially a vapour compression circuit containing a heat transfer fluid, as well as a method for reducing the GWP of a transfer fluid. The invention also relates to heat transfer fluids suited to the implementation of the above methods.
