    Abstract: A system and method are provided including a system controller for a refrigeration or HVAC system having a compressor rack with a compressor and a condensing unit with a condenser fan. The system controller monitors and controls operation of the refrigeration or HVAC system. A rack controller monitors and controls operation of the compressor rack and determines compressor rack power consumption data. A condensing unit controller monitors and controls operation of the condensing unit and determines condensing unit power consumption data. The system controller receives the compressor rack power consumption data and the condensing unit power consumption data, determines a total power consumption of the refrigeration or HVAC system, determines a predicted power consumption or a benchmark power consumption for the refrigeration system, compares the total power consumption with the predicted power consumption or the benchmark power consumption, and generates an alert based on the comparison.

    Abstract: A system and method is provided that includes a system controller for a refrigeration or HVAC system having at least one system component, at least one transmitter beacon associated with the at least one system component and configured to broadcast a signal with information identifying the associated at least one system component, and a mobile device configured to receive the signal. The mobile device is further configured to identify the at least one system component that is closest to the mobile device based on the information from the signal identifying the associated at least one system component and retrieve at least one of configuration and operational data associated with the at least one system component based on the information from the signal identifying the associated at least one system component through communication with a server that is in communication with the system controller.

    Abstract: A system and method for a CO2 refrigeration system includes a compressor, a heat exchanger, a liquid receiver, a first valve, and a valve controller. The heat exchanger operates as a gas cooler when the CO2 refrigeration system is in a transcritical mode and as a condenser when the CO2 refrigeration system is in the subcritical mode. The first valve controls a flow of refrigerant from the heat exchanger to the liquid receiver. The valve controller monitors an outdoor ambient temperature and a pressure of refrigerant exiting the heat exchanger, determines whether the CO2 refrigeration system is in the subcritical mode or in the transcritical mode, determines a pressure setpoint based on the monitored outdoor ambient temperature, and controls the first valve based on a comparison of the determined pressure setpoint and the monitored pressure when the CO2 refrigeration system is in the transcritical mode.
