Abstract
COrefrigeration circuit () for circulating a refrigerant in a predetermined flow direction, comprising in flow direction a heat-rejecting heat exchanger (), a receiver () having a liquid portion () and a flash gas portion (), and subsequent to the receiver () a medium temperature loop () and a low temperature loop (), wherein the medium and low temperature loops () each comprise in flow direction an expansion device (), an evaporator () and a compressor (), the refrigeration circuit () further comprising a liquid line () connecting the liquid portion () of the receiver () with at least one of the medium and low temperature loops () and having an internal heat exchanger (), and a flash gas line () connecting the flash gas portion () of the receiver () via the internal heat exchanger () with the inlet of the low temperature compressor (), wherein the internal heat exchanger () transfers in use heat from the liquid flowing through the liquid line () to the flash gas flowing through the flash gas line ().
