| description | According to certain embodiments, a refrigeration system comprises first and second evaporators, first and second compressors, and a gas cooler. The first and second evaporators receive liquid refrigerant from a flash tank and evaporate the refrigerant to cool a first case and a second case, respectively. The second case has a higher temperature set point than the first case. The first compressor compresses the refrigerant discharged from the first evaporator. The second compressor compresses the refrigerant discharged from the first compressor, flash gas from the flash tank, and the refrigerant discharged from the second evaporator. The gas cooler comprises an air-cooled stage that cools the refrigerant discharged from the second compressor and an evaporative stage that cools the refrigerant discharged from the air-cooled stage. The gas cooler further comprises an outlet that supplies the cooled refrigerant to the flash tank through an expansion valve. |
