Patent ID: 10639653

Abstract:
An air outlet device is disclosed herein. The air outlet device includes a plenum body portion, the plenum body portion defining an air chamber therein, the plenum body portion including an air inlet configured to be coupled to a supply air source for supplying air to the air chamber; an air nozzle portion fluidly coupled to the plenum body portion and including a nozzle inlet and an exit orifice, the air nozzle portion configured to discharge the air from the air chamber at a substantially uniform velocity through the exit orifice; and an air nozzle extension fluidly coupling the air chamber of the plenum body portion to the nozzle inlet of the air nozzle portion, the air nozzle extension being configured to increase an efficiency of the air outlet device by decreasing the pressure drop that occurs when the pressure energy of the air is converted to kinetic energy.
