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.

A refrigeration system includes a plurality of heat exchangers (E, E, E) in cascade, each of said heat exchangers including: a flow () of cold-producing liquefied methane; a high-pressure flow () of a two-phase mixture of refrigerant fluids giving up in heat and including refrigerant fluids having a low normal boiling temperature; and a low-pressure flow () of a cold-producing two-phase mixture of said refrigerant fluids.
