Abstract
A two section damper assembly and method of use is disclosed for avoiding stratification of cooled air in an air conditioning system. The damper assembly is especially adapted for use in variable air volume air conditioning systems that include an economizer. During the economizer mode of operation, the building in which the air conditioning system is installed is cooled at least partially with outside air as opposed to cooling solely by mechanical means and the volume of air that is required may be relatively low. The variable two section damper assembly ensures that an adequate volume of cooling air is taken in and that there is adequate velocity of the outside air and return air to ensure mixing of the outside air with the return air in order to avoid the stratification of the supply air that can occur. The damper assembly is variable in the size of the opened area and in the direction that the individual vanes of the damper assembly are set.
