A method and system is provided that includes a setpoint monitor in communication with a controller that operates equipment according to setpoint values, each setpoint value having an associated benchmark value. The setpoint monitor receives setpoint modifications based on communication with the controller, each setpoint modification corresponding to a modification of a setpoint value to a modified value different from the associated benchmark value. A terminal in communication with the setpoint monitor displays the setpoint modifications and receives input to revert a setpoint modification from the modified value back to the associated benchmark value. The setpoint monitor communicates with the controller to revert the setpoint value associated with the setpoint modification from the modified value back to the associated benchmark value.

System and method for monitoring and evaluating equipment operating parameter modifications

A method and system is provided that includes a controller that operates at least one piece of equipment according to setpoint values and a setpoint monitor in communication with the controller. The setpoint monitor receives setpoint modifications, each setpoint modification corresponding to a modification of one of the setpoint values. The setpoint monitor calculates an expected change in energy consumption of the at least one piece of equipment for each of the setpoint modifications and ranks the setpoint modifications based on the expected change in energy consumption. A first terminal is in communication with the setpoint monitor and displays the setpoint modifications in an order based on the ranking of the setpoint modifications. The first terminal receives input for each setpoint modification of the plurality of setpoint modifications indicating approval or rejection of the setpoint modification.

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.

A method for monitoring a condenser in a refrigeration system includes calculating a thermal efficiency of the condenser based on operation of the condenser and averaging the thermal efficiency over a predetermined period. Further, the method comprises comparing the average to an efficiency threshold and generating a notification based on the comparison. The method may be executed by a controller or stored in a computer-readable medium.

Monitoring a condenser in a refrigeration system

A method for monitoring refrigerant in a refrigeration system includes sensing, a refrigerant pressure of a refrigeration system, averaging the refrigerant pressure over a time period, determining an expected pressure based on said time period, comparing the average to the expected pressure, and determining a system condition based on said comparison. The method may be executed by a controller or stored in a computer-readable medium.

Monitoring refrigerant in a refrigeration system

A method for monitoring refrigerant in a refrigeration system includes calculating a saturation temperature of refrigerant in a refrigeration system based on at least one of a discharge pressure and a discharge temperature of the refrigeration system; calculating an expected refrigerant level based on the saturation temperature; comparing the refrigerant level with the refrigerant level threshold; and generating a leak notification when the receiver refrigerant level is less than the refrigerant level threshold. The method may be executed by a controller or stored in a computer-readable medium.
