Abstract
An aircraft galley compartment cooling system includes a source of chilled air, and a closed compartment with a door. A sensor detects the opening of the door, and sends a signal to the cooling system to deactivate while the door is opened to prevent ambient air from entering the cooling system. Once the door is closed, the cooling system is reactivated. The sensor can be a light sensor, a mechanical sensor, a magnetic sensor, or the like for determining movement or the presence/non-presence of the door to the compartment.
