A composition comprising: (i) 1,1-difluoroethene (vinylidene fluoride, R-1132a); (ii) carbon dioxide (CO, R-744); (iii) pentafluoroethane (R-125); and (iv) one or more of trifluoromethane (R-23) and hexafluoroethane (R-116).

Refrigerant compositions and uses thereof

A method for at least partially draining an operating system, which contains a working fluid including carbon dioxide (R744) and a halogenated hydrocarbon. The method includes transferring the working fluid to a target container, from the operating system, wherein the working fluid is contacted with an absorptive bed. The working fluid may include between 10% and 35% by weight of halogenated hydrocarbon. The method may include an absorptive bed treatment step prior to the contacting step.

Method and an apparatus for at least partially draining an operating system

The invention provides a composition comprising (a) from about 6 to about 18 weight % R-1132a, (b) from about 5 to about 35 weight % R-32, and (c) from about 47 to about 89 weight % R-1234yf. The use of such a composition as a working fluid in a heat pump system of a vehicle, preferably an electric vehicle, is also provided.

Compositions

According to the present invention, there is provided a composition comprising 1,1-difluoroethylene (R-1132a), difluoromethane (R-32), 2,3,3,3-tetrafluoropropene (R-1234yf) and carbo dioxide (CO, R-744). The invention also provides a composition R-1132a, R-32, R-1234yf and at least one compound selected from the group consisting of: pentafluoroethane (R-125), 1,1-difluoroethane (R-152a), 1,1,1,2-tetrafluoroethane (R-134a), trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)) and 1,1,1,2,3,3,3-heptafluoropropane (R-227ea); optionally, the composition comprises at least one further compound selected from the group consisting of trifluoroethylene (R-1123), propane (R-290), propylene (R-1270), isobutane (R-600a) and carbon dioxide (CO, R-744). The present invention also provides a composition comprising R-1132a, R-32 and R-1234yf.

Heat transfer compositions

The invention provides a composition comprising 1,1-difluoroethene (R-1132a), difluoromethane (R-32), 2,3,3,3-tetrafluoropropene (R-1234yf), optionally carbon dioxide (CO, R-744), and, optionally, 1,1,2-trifluoroethene (R-1123).

A refrigerant composition comprising carbon dioxide (CO; R-744) and from 1 to 32 weight % difluoromethane (R-32) based on the total weight of the composition is described. Also described is the use of the refrigerant composition for providing heating and cooling and a refrigeration, air-conditioning or heat pump system comprising the refrigerant composition.
