Abstract
The invention is a double duct changeover HVAC system, which uses two conditioned air sources to deliver air into two main duct systems. The two main duct systems are routed toward the exterior exposures of a building, and converge into a single duct which is routed to heating and cooling zones. Exterior exposure dampers control the mix of air so that the correct air temperature is sent to each exterior exposure. A damper at each heating and cooling zone controls the air flow into each heating and cooling zone, and VAV logic is used to deliver the correct air temperature and air flow to each heating and cooling zone of a building.
