Abstract:
Rooms of a building are provided with an air distributing ceiling and plenum chambers thereabove. Treated air is pumped to the plenum chambers where it passes through the ventilating ceiling to heat or cool an enclosed area below. A recirculation system permits withdrawal of all of the treated air from the enclosed area. The withdrawn air is recirculated after mixing with freshly treated air. The air is treated by passing a portion thereof over a heating or cooling coil while the remainder bypasses the coil. The mixture of treated and bypass air is pumped at a high rate into the plenum chambers where a static pressure such as 1 inch of water exists.
