Abstract: 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.

Abstract: Systems, methods and non-transitory computer readable media may be provided for the management of data related to risk exposure. A system may be provided including one or more utilities configured to receive data from a plurality of data sources; a rules engine for applying one or more logical rules that are triggered by one or more conditions associated with the integrity of the received data; and one or more utilities configured to apply the one or more logical rules to validate received data and automatically request updated data from a subset of the plurality of data sources where the integrity of the received data does not meet a predefined threshold. Other systems may be provided including units configured for the determination of risk exposure, and the identification of a tiered risk exposure analysis. Corresponding methods and non-transitory computer readable media may be provided.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present application provides a refrigeration system with full oil recovery for removing oil from a flow of a refrigerant. The refrigeration system may include a compressor, an oil separator positioned downstream of the compressor to remove most of the oil from the flow of the refrigerant, a condenser positioned downstream of the oil separator, and a receiver positioned downstream of the condenser. The receiver may include a barrier to separate the oil on a first side from the refrigerant on a second side.
