Abstract: Systems and methods for performing dynamic coefficient of performance calculations for refrigeration systems are provided. A controller calculates a weighted Carnot efficiency of a refrigeration case based on outdoor temperature data, refrigeration case temperature data, a case load of a refrigeration case, and a case defrost status of the refrigeration case. The controller calculates a weighted coefficient of performance based on based on a refrigerant type, the case load of the refrigeration case, the case defrost status of the refrigeration case, and at least one of the of the refrigeration case temperature data and pressure data. The controller calculates a system performance index (SPI) for the refrigeration case based on the weighted Carnot efficiency of the refrigeration case and weighted actual Carnot efficiency. The controller generates, in response to the SPI being below a threshold, an output indicating that the refrigeration case is operating below a threshold efficiency.

Abstract: Systems and methods are provided and include a case controller for a refrigeration case of a refrigeration system. The case controller is configured to: determine an evaporator saturated suction temperature (SST) of an evaporator of the refrigeration case; control an evaporator pressure regulator of the refrigeration system based on a comparison of the evaporator SST with an evaporator saturated suction temperature (SST) setpoint; receive an air temperature value from an air temperature sensor associated with the refrigeration case; determine whether the air temperature value is within a predetermined range of an air temperature setpoint; and adjust the SST setpoint in response to the air temperature value being outside of the predetermined range of the air temperature setpoint.

Abstract: A system and a method are provided including a controller for a refrigeration or HVAC system having a compressor rack with at least one compressor. The controller communicates with a tracking module configured to diagnose health of a compressor in the compressor rack. In response to rated performance data for the compressor being unavailable, the tracking module is configured to generate baseline data for the compressor and to diagnose health of the compressor by comparing operational data of the compressor to the baseline data for the compressor. In response to the rated performance data for the compressor being available, the tracking module is configured to diagnose health of the compressor by comparing the operational data of the compressor to the rated performance data for the compressor.

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 are provided for activating and deactivating heating or cooling stages of a heating, ventilating, and air conditioning (HVAC) unit, which includes activating a heating or cooling stage of the HVAC unit based on a determined need for heating or cooling. A monitored temperature is compared with a first temperature setpoint and a monitored on-time of the heating or cooling stage is compared with a first time period setpoint. The heating or cooling stage is deactivated based on the comparison of the monitored temperature with the first temperature setpoint, when the monitored on-time is greater than the first time period setpoint. The monitored temperature is then compared with a second temperature setpoint. The heating or cooling stage is reactivated based on a comparison of the monitored temperature with the second temperature setpoint, when a monitored off-time is greater than the second time period setpoint.

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.

Abstract: A system and a 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. The system controller determines a flood-back discharge temperature corresponding to a flood-back condition, receives an actual discharge temperature associated with the compressor rack, compares the actual discharge temperature with the flood-back discharge temperature, and generates a notification to the rack controller based on the comparison.
