Abstract
A method of operating a system for conditioning air including a variable speed blower for flowing the conditioned air through a contained space having a static pressure therein. In this system, the speed of the blower is set to effect a preselected flow rate at an existing static pressure in the contained space, and the speed of the blower is altered only in response to a variation in the static pressure and only in following relation with the static pressure variation. The speed alteration of the blower is sensed, and the speed of the blower is adjusted in following relation with the sensed speed alteration to establish the preselected flow rate through the contained space at the varied static pressure acting on the blower. A system for conditioning air and a circuit are also disclosed.
