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 display of multiple data sets related to building systems is provided. A first building system includes a first sensor that generates first operating data corresponding to the first building system. A second building system includes a second sensor that generates second operating data corresponding to the second building system. A data server stores the first operating data and the second operating data. A user terminal accesses the first operating data and the second operating data, receives user input selecting the first operating data and the second operating data for display, and displays the first operating data and the second operating data together in a graphical display.
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 method and system is provided that includes receiving a current setpoint value from a controller that operates at least one piece of equipment according to the current setpoint value, the current setpoint value being set by a first user, comparing the current setpoint value with a benchmark setpoint value, and outputting the current setpoint value and the benchmark setpoint value on a terminal when the current setpoint value is different than the benchmark setpoint value. The method and system also includes receiving, with the terminal, input from a second user indicating one of approval of the current setpoint value or rejection of the current setpoint value, notifying the first user that the current setpoint value has been rejected when the input from the second user indicates rejection of the current setpoint value, and communicating, to the terminal, input from the first user indicating one of agreement or disagreement with the rejection of the current setpoint value.
Abstract:
A refrigerant leak detection system is herein disclosed. The system can detect the existence of a slow leak based on the refrigerant level and the system data. They system uses data models, either stored or dynamically created, to calculate an expected refrigerant level. Based on the expected refrigerant level and the actual refrigerant level and statistical process control data, a leak can be identified.

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.
