US Patent 7152415 Refrigerated compartment with controller to place refrigeration system in sleep-mode

A refrigeration system is employed to cool a refrigerated compartment in a kitchen or restaurant. An electronic refrigeration controller controls various aspects of the refrigerated compartment, including temperature. When a push button is pressed, a “sleep-mode” is activated to safely shut the refrigeration system down and turn the evaporator fan off. An employee can then stock or remove inventory from the refrigerated compartment without cool air blowing on the employee. After a predetermined amount of time, the sleep-mode ends and cool air blows into the refrigerated compartment.
