Abstract: Environmentally friendly refrigerant blends utilizing refrigerants including 2,3,3,3-tetrafluoropropene (HFO-1234yf), difluoromethane (HFC-32), and 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: 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: Disclosed is an immersion cooling unit including an immersion cell, defining an internal cavity. An electrical component is positioned in the internal cavity. A dielectric working fluid partially fills the internal cavity and at least partially immerses the electrical component. A condensing coil, is positioned above the dielectric working fluid. The dielectric working fluid comprises at least one of 1,1,1,2,2,5,5,6,6,6-decafluoro-3-hexene, (HFO-153-10mczz), or 1,1,1,4,5,5,5-heptafluoro-4-trifluoromethyl-2-pentene, (HFO-153-10mzzy). Also disclosed is a method of cooling an electrical component, comprising partially immersing an electrical component in a working fluid; and transferring heat from the electrical component using the working fluid
