Abstract
Control system in refrigerator apparatus including a freezer compartment having a quick-chilling chamber with a door for access to the interior thereof from outside the freezer compartment. There is a timer-operated fan to introduce cold air from the freezer compartment into the quick-chilling chamber and means to maintain the chamber at above-freezing temperatures after termination of fan operation. A display panel accessible to the user may be used to manually select the desired chill temperature of the item, the quantity of the item and the unit size of the item. A sensor determines the temperature of the air being introduced into the quick-chilling chamber. All of the input values are accumulated in the memory of a microcomputer and by comparing the values the microcomputer will predict when the item to be chilled will reach the desired temperature and set the timer run time accordingly. A manual switch is provided for starting the timer to run.
