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.

An air-cooled refrigerator and a control method, a control system and controller for defrosting thereof are provided. The high-temperature air of the air-cooled refrigerator exchanges heat with the evaporator in the air duct and is sent into a refrigerating compartment through the operation of a fan; when the evaporator is gradually frosted, the heat-exchanged air suffers the resistance from the frosts on the evaporator during the flow and the fan slows down. Based on this principle, the fan speed can directly correspond to the frost accumulation mass of the evaporator. The actual frost accumulation mass of the evaporator can be directly determined by determining the fan speed. When the fans peed is decreased to a certain low speed, it means that there is much frost on the evaporator and the defrosting needs to be started timely. As a result, the problems of large energy consumption and poor fresh-keeping effect caused by the traditional control method of defrosting in advance or delayed defrosting can be solved, and the energy-saving and fresh-keeping effects of the air-cooled refrigerator can be improved.
