Abstract
A transcritical refrigeration system includes a gas cooler/condenser; a receiver configured to collect refrigerant produced by the refrigeration system; a gas bypass valve fluidly coupled to the outlet of the receiver and operable to control a pressure of the refrigerant in the receiver; and a medium temperature subsystem. The medium temperature subsystem includes one or more expansion valves; one or more medium temperature evaporators; and a suction group including one or more transcritical compressors operable to compress gas refrigerant and discharge the compressed gas refrigerant into a discharge line. The system includes a superheat control system that includes a heat exchanger system including a first side configured to carry gas refrigerant passing between the gas cooler/condenser and an inlet of the receiver, and a second side in heat transfer communication with the first side.
