Abstract
Abstract A vapor compression cycle device is described which includes a multi-component working fluid mixture, condensing heat exchanger and an associated vapor-liquid separator connected to the compressor, a high-pressure liquid accumulator connected to the condenser and associated separator, a flow restricting device connected to the condenser and associated separator, an evaporating heat exchanger and associated low-pressure accumulator connected to the flow restricting device, and the evaporating heat exchanger and low-pressure accumulator connected to the compressor. A method is described also to modulating the capacity of such a device.
