An azeotropic-like mixture composition comprising 1,1,1,3,3,3-hexafluoroisopropylmethylether and hexafluoroisopropanol,
- wherein 1,1,1,3,3,3,-hexafluoroisopropylmethylether is contained at a ratio higher than or equal to 90% by mass and lower than or equal to 99.9% by mass.
An azeotropic-like mixture heat transfer composition comprising 1,1,1,3,3,3-hexafluoroisopropylmethylether and hexafluoroisopropanol, wherein 1,1,1,3,3,3-hexafluoroisopropylmethylether is present in the composition at a ratio higher than or equal to 33.0% by mass and lower than or equal to 99.9% by mass.
A heat transfer method using a high-temperature heat pump device accommodating a heat transfer composition, the method comprising the steps, performed sequentially, of:
- evaporating the heat transfer composition in an evaporator;
- compressing the heat transfer composition in a compressor;
- condensing the heat transfer composition in a condenser;
- and
- reducing the pressure of the heat transfer composition in an expansion valve;
- wherein the heat transfer composition comprises 1,1,1,3,3,3-hexafluoroisopropylmethylether and hexafluoroisopropanol, and has a condensation temperature higher than or equal to 70° C.
