ABSTRACT:
An airflow register for an air conditioning system for an enclosure such as room within a house or an office within a building. The register includes a series of louvers which can be located in either an open position or a closed position. The open position permits air to flow through the register and the closed position prevents air from flowing through the register. Louvers are to be movable by a motor with this motor being operated by a light sensor mounted on the exterior surface of the register. Upon an observable lightened environment being detected by the light sensor, the motor is activated which will locate the louvers in the open position. Upon an observable darkened condition being sensed by the light sensor, the motor is activated which will locate the louvers in the closed position. A flow limiter may be used to keep the louvers slightly open when in the closed position to have some heated air enter the room when the ambient temperature is severely cold.
