ABSTRACT:
An air handling system is provided which includes sections for the introduction of outside or ambient air relative to a structure to be mixed with a flow of inside or return air in a flow path in which the resulting mixture is impelled by a fan to be discharged through a plurality of radially disposed vents. The temperatures of the ambient and inside air as well as of the discharge air is converted into signals which are fed into a microprocessor which in turn generates signals to control dampers which in turn controls the rates of flow of inside and outside air into the principal flow path which is controlled by the aforementioned fan which generates a constant rate of flow through the discharge air vents. The temperature of the discharge air is used to control the ratio of the flows of ambient and inside air which collectively constitute the discharge air.
