Abstract: Environmentally friendly refrigerant blends utilizing refrigerants including 2,3,3,3-tetrafluoropropene (HFO-1234yf), 1,2-difluoroethylene, at least one hydrocarbon selected from the group consisting of propane, cyclopropane, propylene, isobutane, and n-butane, and optionally 1,1-difluoroethane (HFC-152a). The blends have low GWP, low toxicity, and low flammability with low temperature 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.

Abstract: 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.

Abstract: Refrigerant compositions including 2,3,3,3-tetrafluoropropene (HFO-1234yf) and at least one of ethane (R-170) or propane (R-290) which exhibit near-azeotropic or azeotrope-like behavior. The refrigerant compositions exhibit a low global warming potential (GWP) and are non-ozone depleting. The refrigerant compositions are useful as a heating or cooling fluids in a variety of heating or cooling systems including heat pumps and other heating and cooling loops, in, for example, the automotive industry.

Abstract: A method of producing a fluoroolefin includes contacting a compound of formula (1), RfCX1═CHCF3, with a fluorinated ethylene compound of formula (2), CX2X3═CX4X5 in the presence of a catalyst. In the compound of formula (1), Rf is a linear or branched C1-C10 perfluorinated alkyl group and Xi is H, Br, Cl, or F. In the compound of formula (2), X2, X3, X4, and X5 are each independently H, Br, Cl, or F and at least three of X2, X3, X4, and X5 are F. The resulting composition comprises a compound of formula (3), Rf(CF2)nCX6═CH(CF2)mCX7X8CFX9X10. In the compound of formula (3), X6, X7, X8, X9, and X10 are each independently H, Br, Cl, or F, and the total number of each of H, Br, Cl, and F corresponds to the total number of each of H, Br, Cl, and F provided by the compounds of formulae (1) and (2).

Abstract: A refrigeration system including a flooded evaporator. The flooded evaporator additionally includes a liquid evaporator refrigerant composition and a vapor evaporator refrigerant composition. The liquid refrigerant composition includes difluoromethane (HFC-32), and 2,3,3,3-tetrafluoropropene (R-1234yf) and the vapor refrigerant composition includes difluoromethane (HFC-32), and 2,3,3,3-tetrafluoropropene (R-1234yf). The mass fraction of difluoromethane in the liquid evaporator refrigerant composition is lower than the mass fraction of difluoromethane in the vapor evaporator refrigerant composition and the mass fraction of 2,3,3,3-tetrafluoropropene in the liquid evaporator refrigerant composition is greater than the mass fraction of 2,3,3,3-tetrafluoropropene in the vapor evaporator refrigerant composition.
