Abstract
A refrigeration system () has A) an ejector circuit () comprising: Aa) a high pressure compressor unit () comprising at least one compressor (); Ab) a heat rejecting heat exchanger/gas cooler (); Ac) an ejector (); Ad) a receiver () having a gas outlet () which is connected to an inlet of the high pressure compressor unit (). B) a normal cooling temperature flowpath () comprising in the direction of flow of the refrigerant: Ba) a normal cooling temperature expansion device () fluidly connected to a liquid outlet () of the receiver (); Bb) a normal cooling temperature evaporator (); Bc) an ejector secondary inlet line () with an ejector inlet valve () fluidly connecting an outlet () of the normal cooling temperature evaporator () to a suction inlet () of the ejector (); and Bd) a normal cooling temperature flowpath valve unit () configured for fluidly connecting the inlet of the high pressure compressor unit () selectively either to the gas outlet () of the receiver () or to the outlet () of the normal cooling temperature evaporator (); C) a freezing temperature flowpath () comprising in the direction of flow of the refrigerant: Ca) a freezing temperature expansion device () fluidly connected to the liquid outlet () of the receiver (); Cb) a freezing temperature evaporator (); Cc) a freezing temperature compressor unit () comprising at least one freezing temperature compressor (); and Cd) a freezing temperature flowpath valve unit () configured for fluidly connecting the outlet of the freezing temperature compressor unit () selectively either to the inlet of the high pressure compressor unit () or to the ejector inlet valve ().
