20120191498 | DISPATCH MANAGEMENT MODEL - A method is provided and includes detecting a fault condition in a refrigeration system, determining a maintenance cost to correct the fault condition, and determining a monetary value associated with continued operation of the refrigeration system with the fault condition. The method also includes comparing the maintenance cost to the monetary value and determining a level of urgency for correcting the fault condition based on the comparison. The method also includes scheduling maintenance to correct the fault condition based on the level of urgency. | 07-26-2012 |
20120060529 | REFRIGERATION SYSTEM ENERGY MONITORING AND DIAGNOSTICS - A management center is configured to communicate with a controller for an energy consuming system at a remote location, to receive ambient temperature data corresponding to an ambient temperature at the remote location, to calculate a projected energy consumption value for at least one component of the energy consuming system based on the ambient temperature data, to receive an actual energy consumption value for the at least one component from the controller, to compare the actual energy consumption value with the projected energy consumption value, and to generate an output based on the comparison. | 03-15-2012 |
20110112814 | REFRIGERANT LEAK DETECTION SYSTEM AND METHOD - 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. | 05-12-2011 |
20110071960 | System For Monitoring Optimal Equipment Operating Parameters - A method includes obtaining a present value of a set point for at least one piece of equipment with a remote monitor in communication with a controller that controls the at least one piece of equipment according to the set point. The method also includes determining a first power consumption rate with the remote monitor. The first power consumption rate corresponds to power consumption of the at least one piece of equipment while operating at the present value of the set point. The method also includes determining a second power consumption rate with the remote monitor. The second power consumption rate corresponds to power consumption of the at least one piece of equipment while operating at a predetermined benchmark value of the set point. The method also includes determining a monetary cost associated with a difference between the first power consumption rate and the second power consumption rate, based on a power consumption cost, when the first power consumption rate is greater than the second power consumption rate. The method also includes communicating the monetary cost, with the remote monitor, to a remote user. | 03-24-2011 |
20100305718 | SYSTEM AND METHOD FOR MONITORING AND EVALUATING EQUIPMENT OPERATING PARAMETER MODIFICATIONS - 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. | 12-02-2010 |
20100179703 | REFRIGERATION SYSTEM ENERGY MONITORING AND DIAGNOSTICS - A management center is configured to communicate with a refrigeration system controller for a refrigeration system at a remote location. The management center is configured to receive ambient temperature data corresponding to an ambient temperature at the remote location, to calculate a projected energy consumption value for at least one component of the refrigeration system based on the ambient temperature data, and to receive an actual energy consumption value for the at least one component from the refrigeration system controller. The management center is also configured to compare the actual energy consumption value with the projected energy consumption value and to generate an output based on the comparison. | 07-15-2010 |
20090077983 | SYSTEM AND METHOD FOR MONITORING A COMPRESSOR OF A REFRIGERATION SYSTEM - A system includes a compressor temperature sensor that generates a compressor discharge temperature signal corresponding to a compressor of a refrigeration system, a compressor pressure sensor that generates a compressor discharge pressure signal corresponding to the compressor, and a controller processing the signals over a predetermined time period. The processing includes calculating a discharge saturation temperature based on the compressor discharge pressure signal, calculating compressor superheat data based on the compressor discharge temperature signal and the discharge saturation temperature, accumulating the compressor superheat data over the predetermined time period, and comparing the accumulated compressor superheat data to a predetermined threshold. The controller generates an alarm indicating a compressor fault based on the comparing. | 03-26-2009 |
