Abstract
The present invention relates to a frost and freezing (freeze-up) prevention control system for improving the efficiency of a cooling system commonly found in refrigerators, refrigerated vending machines, and or beverage coolers. Furthermore, the present invention can be retrofit onto, or originally manufactured into a cooling system. Suitable cooling systems are those commonly found in refrigerators, refrigerated vending machines and refrigerated beverage coolers. The present invention monitors, controls, and improves the efficiency of the refrigeration cycle by preventing the refrigerated cooling system from accumulating frost and or ice on critical cooling system components. Furthermore, by controlling the refrigeration cycle the present invention maintains a high level of cooling system efficiency and reduces the electrical power consumption required to operate the cooling system over the operational life of the cooling system.
