Abstract:
An air handling system selectively operable in a full load condition and a low load condition to meet a cooling demand of a comfort zone by providing supply air to the comfort zone, comprising:a housing defining a return air inlet, a outside air inlet, a supply air outlet, a return air chamber, a precoil mixing area, and a postcoil mixing area, wherein the outside air inlet leads into the precoil mixing area; a cooling coil disposed downstream of the precoil mixing area and upstream of the postcoil mixing area and being adapted to cool air moving from the precoil mixing area to the postcoil mixing area; a damper system disposed downstream of the return air chamber and being adapted to receive air from the return air chamber and apportion the air to the precoil mixing area and the postcoil mixing area, wherein the temperature of supply air in the postcoil mixing area is higher in the low load condition than in the full load condition; and a blower coupled to the housing and being adapted to move supply air from the postcoil mixing area to the comfort zone, wherein the blower moves the supply air at a higher flow rate in the full load condition than at the low load condition.
