Abstract
An air conditioning system for conditioning the air in a plurality of enclosed areas in a building. Conditioned air at a temperature level which may be varied is supplied to a first terminal for discharge into an area. Conditioned air at a relatively constant temperature level is delivered to a second terminal for discharge into the area. The quantity of constant temperature air discharged into the area is regulated in accordance with the temperature level therein. The quantity of the variable temperature air stream discharged into the area is regulated in accordance with the quantity of constant temperature air discharged into the area. As the quantity of constant temperature air discharged into the room is increased, the quantity of variable temperature air discharged into the room will be decreased if the variable temperature air supply is at a relatively warm level, and may be increased if the variable temperature air supply is at a relatively cold level; and as the quantity of constant temperature air discharged into the room is decreased, the quantity of variable temperature air discharged into the room will be increased if the variable temperature air supply is relatively wa…
