Abstract
The present invention relates to an integrated air-conditioning (A/C) circuit for a Carbon Dioxide (CO2) refrigeration system having a CO2 based refrigerant circuit including a high pressure refrigerant cooling heat exchanger that passes refrigerant received at a high pressure in heat exchange relationship with a cooling medium. The A/C circuit is nested within the CO2 refrigeration system and includes a means of directing discharge from an outlet line of the refrigerant cooling heat exchanger into the nested air-conditioning circuit. The A/C circuit further includes a means of reducing the pressure of the refrigerant directed from the outlet line of the refrigerant cooling heat exchanger, and a refrigerant heating heat exchanger for receiving the refrigerant having a reduced pressure and passing the refrigerant in heat exchange relationship with a heating medium to generate chilled fluid.
