Abstract
A refrigeration system includes a refrigeration subsystem and a coolant subsystem. The refrigeration subsystem is configured to circulate a refrigerant between an evaporator () within which a refrigerant absorbs heat and a gas cooler/condenser () within which the refrigerant rejects heat to provide cooling to a temperature-controlled space. The coolant subsystem includes a heat exchanger () coupled to the refrigeration subsystem at an outlet of the gas cooler/condenser and configured to transfer heat from the refrigerant exiting the gas cooler/condenser to an external coolant when the external coolant flows through the heat exchanger, a control valve (), and a controller () configured to operate the control valve to control a flow of at least one of the refrigerant or the external coolant through the heat exchanger based on a temperature of the external coolant relative to a temperature of the refrigerant exiting the gas cooler/condenser.
