A system that uses analytics to predict typical door opening patterns and executes an anticipatory chilling period that lowers the temperature of the food so that the expected door opening event does not increase the temperature of the food above the optimal storage temperature point.

System and Method to optimize food freshness in a refrigerator /freezer
The purpose of a refrigerator and freezer is to keep food from going bad. The appliance has evolved to perform this function admirably and the state of the art has very user friendly features and high energy efficiency. The focus of the control systems within an advanced refrigerator is to keep the temperature set at the appropriate point that will inhibit bacterial and mold growth. This is managed simply by monitoring temperature sensors within the body of the refrigerator or freezer compartment and responding to increased temperatures by running the cooling apparatus to lower the temperature back to the appropriate point. The units sometimes have special ducting and fans to control the temperature in various zones.
The problem with this approach is that food will still be subjected to increased temperatures when the door gets opened repeatedly as happens in a busy household , or when it is loaded with a fresh batch of higher temperature foods recently acquired from the grocery . The refrigerator attempts to respond to this temp increase but the damage has already been done to the existing food . And the freshness life of the food has been diminished .
This invention addresses this problem by using analytics to predict typical door opening patterns and executes an anticipatory chilling period that lowers the temperature of the food so that the expected door opening event does not increase t...
