Abstract
A refrigeration system control apparatus for use with an ice bank for sequentially cycling a refrigerator compressor on and off based on sensed conditions. The system includes a first temperature probe located a first distance from a refrigerator evaporator coil and a second temperature probe located a second, greater distance from the refrigerator evaporator coil. A programmable controller monitors temperature outputs from the first and second temperature probes and turns on and off the refrigerator compressor based upon a rate of change of the temperature difference between the sensed temperatures of the first and second probes.
