Systems and methods have demonstrated the capability of rapidly cooling the contents of pods containing the ingredients for food and drinks.

Environmentally friendly refrigerant blends utilizing blends including 2,3,3,3-tetrafluoropropene (HFO-1234yf) and fluoroethane (HFC-161). The blends have ultra-low GWP, low toxicity, and low flammability with low temperature glide or nearly negligible glide for use in a hybrid, mild hybrid, plug-in hybrid, or full electric vehicles for thermal management (transferring heat from one part of the vehicle to the other) of the passenger compartment providing air conditioning (A/C) or heating to the passenger cabin.

Heterogenous azeotrope or azeotrope-like compositions comprising 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) and water which may include from about 0.05 wt. % to about 92.01 wt. % 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) and from about 7.99 wt. % to about 99.95 wt. % water and having a boiling point between about—13.5° C. and about 14.5° C. at a pressure of between about 12.5 psia and about 16.5 psia. The azeotrope or azeotrope-like compositions may be used to separate impurities from 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb).

A method of making chlorofluorohydrocarbons including, contacting, a fluorinated hydrocarbon reagent in the vapor phase, with hydrogen chloride (HCl). The reaction is conducted in the presence of an effective amount of a catalyst, at an elevated temperature sufficient to effect hydrochlorination to form a reaction mixture including a chlorofluorohydrocarbon.

High boiling fluorinated by-products obtained from a manufacturing process of 1-chloro-3,3,3-trifluoropropene (HFO-1233zd) not only include components that can be used as a starting material or feedstock in the production of 1,1,1,3,3-pentafluoropropane (HFC-245fa), but also contain impurities that can be detrimental in the HFC-245fa process. A method of providing an improved composition from the high boiling by-products obtained from an HFO-1233zd manufacturing process reduces these impurities. The improved composition can be used as a starting material or feedstock for the production of HFC-245fa.

Refrigerant for a refrigeration device (1) comprising a gas mixture, said gas mixture comprising at least carbon dioxide, 1,1,1,2-tetrafiuoroethane and difluoromethane, characterised in that carbon dioxide has a mass percentage higher than 50 % in relation to the total mixture.

No studies have been made regarding what kinds of refrigerants should be used in a refrigeration cycle device for a vehicle. An air conditioner (1) for a vehicle includes a refrigerant circuit (10) and a refrigerant that is sealed in the refrigerant circuit (10). The refrigerant circuit (10) includes a compressor (80), a first heat exchanger (85), which serves as a heat dissipater in a dehumidifying heating mode, an outside-air heat exchanger (82), a cooling control valve (87), and a second heat exchanger (86), which serves as an evaporator in the dehumidifying heating mode. The refrigerant is a refrigerant having a low GWP.

The present invention provides a composition, such as a refrigerant composition comprising 1,1-difluoroethene (vinylidene fluoride, R-1132a); trifluoromethane (R-23); and one or more compound selected from hexafluoroethane (R-116), ethane (R-170) and carbon dioxide (R-744, CO.sub.2).
