Abstract:
Systems and method for operating and monitoring refrigerators are described. Temperature cycles within the compartment are characterized using statistical, frequency and pattern analysis techniques to derive a steady-state characteristic of temperature within the compartment. A thermal sensor inside the conditioned area is monitored and temperature data sets can be analyzed to determine performance in comparison to a baseline, and energy consumption. Analysis of continuous temperature readings taken from individual or groups of freezers identifies patterns of variations in temperature cycles from which feedback on efficiency can be inferred. Electrical load can be determined by measuring or estimating current usage and identifying periods of time when compressors are active in the refrigerator.

Claim (Index 1):
A method of monitoring operational efficiency of a refrigeration system, comprising:\n configuring a controller to collect data from one or more sensors, wherein the controller is located outside a cooled compartment of a monitored refrigeration system and communicatively coupled to the one or more sensors; receiving a plurality of measurements obtained by at least one sensor of the one or more sensors, wherein the plurality of measurements includes periodic measurements of temperature, current or vibration associated with operation of the monitored refrigeration system over a period of time; generating an operational characteristic of the monitored refrigeration system from the plurality of measurements; identifying a trend in the operational characteristic of the monitored refrigeration system that indicates a variation from a nominal operational characteristic; and predicting failure or loss of energy efficiency of the monitored refrigeration system based on the trend identified in the operational characteristic of the monitored refrigeration system, wherein the nominal operational characteristic includes measurements of temperature, current or vibration obtained from a nominally operating refrigeration system.
