Abstract: A multi-step method is disclosed for exchanging heat in a vapor compression heat transfer system having a working fluid circulating therethrough. The method includes the step of circulating a working fluid comprising a fluoroolefin to an inlet of a first tube of an internal heat exchanger, through the internal heat exchanger and to an outlet thereof. Also disclosed are vapor compression heat transfer systems for exchanging heat. The systems include an evaporator, a compressor, a dual-row condenser and an intermediate heat exchanger having a first tube and a second tube. A disclosed system involves a dual-row condenser connected to the first and second intermediate heat exchanger tubes. Another disclosed system involves a dual-row evaporator connected to the first and second intermediate heat exchanger tubes.

Abstract: A dehydrohalogenation product includes a hydrochlorofluorocarbon mixture of a fluoroolefin of formula RCX═CZQ and a halofluoroalkane of formula RCXYCZQT. R is a perfluorinated alkyl group and X, Z, and Q are independently H or halogen. One of Y and T is H and the other is Cl, Br, or I. About 80% or greater of the hydrochlorofluorocarbon mixture is the fluoroolefin. The dehydrohalogenation product also includes a caustic agent and a solvent. In some embodiments, the dehydrohalogenation product is free of any catalyst, including any phase transfer catalyst.
