ABSTRACT:
A valve is provided that controls the type of air reaching an air conditioning blower. For example, in one position of the valve, returned, air conditioned air is continually recirculated to the blower without the addition of any fresh air. In another position of the valve the recirculated air is prevented from reaching the blower and only fresh air can flow to the air conditioner blower. The valve can also be located in an infinite number of positions wherein various mixtures of fresh and recirculated air are directed to the air conditioning blower. The valve is positioned by a motor which is in turn controlled by a sensor. The valve mechanism is mounted in a housing which may be included as a part of an original air conditioning system or may be attached to an existing system as a retrofit.
