Abstract
An integrated Energy Management and/or Control System method and apparatus that continually monitors power consumption on each piece of equipment 2417 and performs detailed analyses of energy consumption curves including derivatives and compares data to historical data on the same equipment as well as going online and acquiring manufacturers specs and comparing to that as well as the same model number equipment in the same or other locations, in order to detect anomalies, abnormal energy consumption or provide early warning of equipment failures.
Claims16
A management center configured for receiving, real-time energy consumption data from a multiplicity of equipment at a multiplicity of sites and adaptively deriving a time domain and a frequency domain signature for each category of equipment by type or model number to project energy consumption value for similar types or model numbers of equipment at a multiplicity of sites;
- receiving, with the management center, an actual energy consumption value for one piece of energy consuming equipment;
- cross-correlating, with the management center, the actual energy consumption value with the energy consumption value projected by the signature;
- and generating, with the management center, an output based on the cross-correlation.
A central facility monitoring many locations, including stores, to show a regional or world map of the aggregate stores which may be popped-up from hierarchically organized pages.
A system for extracting a refrigeration device's “sinus rhythm” or “signature” and tracking these devices in order to detect anomalies.
A system for detecting thermostat overrides on refrigeration and HVAC units by logging in remotely using security credentials and controlling the refrigeration or HVAC, based on the slope of the curve of the temperature, and/or the energy consumption curve to alert someone to disable the override.
A battery powered wireless integrated temperature, pressure, and humidity sensor in a single tiny enclosure measuring less than 3 cubic inches, using a single ½ AA battery capable of lasting more than 3 years.
A system for deriving the Fourier Heat Flow Coefficient of a refrigeration system by using variations in KWh input versus BTU output relative to circadian cycle temperatures which normally follow a diurnal pattern.
