Abstract
An integrated CO2 refrigeration and air conditioning (AC) system for use in a facility includes one or more CO2 compressors configured to discharge a CO2 refrigerant at a higher pressure for circulation through a circuit to provide cooling to one or more refrigeration loads in the facility and a receiver configured to receive the CO2 refrigerant at a lower pressure through a high pressure valve. The integrated system further includes an AC module configured to deliver a chilled AC coolant to AC loads in the facility. The AC module includes an AC evaporator and an AC compressor. The AC evaporator has an inlet configured to receive CO2 liquid and an outlet configured to discharge a CO2 vapor. The AC compressor is arranged in parallel with the one or more CO2 compressors and is configured to receive CO2 vapor from both the AC evaporator and the receiver.
