摘要： A system includes a temperature sensor, a pressure sensor, and a controller. The temperature sensor measures a temperature of a refrigerant at a compressor. The compressor receives the refrigerant from a second compressor. The pressure sensor measures a pressure of the refrigerant at the compressor. The controller receives one or more of the measured temperature and the measured pressure and determines that one or more of the measured temperature and the measured pressure exceed a threshold. In response to that determination, the controller actuates a pulse valve coupled to a liquid injection line. The pulse valve controls the flow of a liquid refrigerant from a flash tank through the liquid injection line to mix with the refrigerant at the compressor.

摘要： An absorption subcooler comprises a first heat exchanger operable to receive refrigerant from a compressor of a refrigeration system and apply a first cooling stage to the refrigerant. The absorption subcooler is further operable to discharge the refrigerant to a gas cooler operable to apply a second cooling stage to the refrigerant.

摘要： A system includes a flash tank, a load, a first compressor, a second compressor, and a liquid injection line. The flash tank stores a refrigerant. The load uses the refrigerant from the flash tank to remove heat from a space proximate the load. The first compressor compresses the refrigerant from the load. The second compressor compresses the refrigerant from the first compressor. The liquid injection line is coupled to the flash tank and to the second compressor and sends a liquid refrigerant from the flash tank to mix with the refrigerant from the first compressor before the refrigerant from the first compressor is received by the second compressor.

摘要： A system includes a flash tank, a load, a first compressor, a second compressor, a refrigerant routing line, and a flash gas bypass line. The flash tank stores a refrigerant. The load uses the refrigerant from the flash tank to remove heat from a space proximate the load. The first compressor compresses the refrigerant from the load. The refrigerant routing line routes the refrigerant from the first compressor to the flash tank below a liquid level line of the flash tank. The flash gas bypass line is coupled to the flash tank and sends the refrigerant as a flash gas from the flash tank to the second compressor. The second compressor compresses the refrigerant.

摘要： A system includes a high side heat exchanger, a flash tank, an air conditioner load, an air conditioner ejector, a refrigeration load, a first compressor, a second compressor, and a vapor ejector. The high side heat exchanger removes heat from a refrigerant. The flash tank stores the refrigerant from the high side heat exchanger. The air conditioner load uses the refrigerant from the flash tank to remove heat from a first space proximate the air conditioner load. The air conditioner ejector pumps the refrigerant from the air conditioner load to the flash tank. The refrigeration load uses the refrigerant from the flash tank to remove heat from a second space proximate the refrigeration load. The first compressor compresses the refrigerant from the refrigeration load. The second compressor compresses a flash gas from the flash tank. The vapor ejector pumps the refrigerant from the refrigeration load to the flash tank.
