ABSTRACT:
In an air conditioning system, the positions of the dampers in the outside air duct and the return air duct are changed periodically during periods of mechanical refrigeration. The temperature of the refrigerated air is sensed and compared with the temperature of the refrigerated air sensed prior to the change in damper positions. The positions of the dampers are controlled in accordance with the lowest temperature detected.
