  • Transcritical system with enhanced subcooling for high ambient temperature
    Patent number: 10830499
    Abstract: In certain embodiments, a transcritical refrigeration system provides refrigeration by circulating refrigerant through the system. The system includes a gas cooler, a heat exchanger, a high pressure expansion valve, a flash tank, refrigeration cases, and compressors. The gas cooler cools the refrigerant to a first temperature. The heat exchanger cools the refrigerant flowing from the gas cooler to the high pressure expansion valve to a second temperature. The high pressure expansion valve is coupled to the flash tank, which is coupled to the refrigeration cases. The refrigeration cases are coupled to the compressors, which are coupled to the gas cooler. An expansion valve between the gas cooler and the heat exchanger may cool the refrigerant flowing to the heat exchanger. A high pressure vapor compressor between the heat exchanger and the gas cooler may compress the refrigerant flowing from the heat exchanger to the gas cooler.
