CARBON DIOXIDE COOLING SYSTEM WITH SUBCOOLING

摘要

A system includes a first heat exchanger, a flash tank, a first compressor, a condenser, a second heat exchanger, and a second compressor. The first heat exchanger removes heat from carbon dioxide refrigerant. The flash tank stores the carbon dioxide refrigerant from the first heat exchanger. The first compressor compresses the carbon dioxide refrigerant and sends the compressed carbon dioxide refrigerant to the first heat exchanger. The condenser removes heat from a second refrigerant. The second heat exchanger receives the second refrigerant from the condenser. The second heat exchanger further removes heat from the carbon dioxide refrigerant stored in the flash tank. The second compressor compresses the second refrigerant from the heat exchanger. The second compressor sends the second refrigerant to the condenser.
