Patent number: 11761642Abstract: An air diffuser of a heating, ventilation, and/or air conditioning (HVAC) system includes a mixing chamber having a circulation inlet and a mixing region, a room air intake fluidly coupled with the circulation inlet and separated from the mixing region by a blank-off plate, and a nozzle. The nozzle is disposed adjacent to the circulation inlet and configured to accelerate a conditioned air flow into the mixing region such that unconditioned room air is induced by the conditioned air flow to enter the mixing region through the circulation inlet and from the room air intake.Type: GrantFiled: August 22, 2022Date of Patent: September 19, 2023Assignee: Air Distribution Technologies IP, LLCInventors: Ryan M. Perkinson, Kazim C. Demirhan, Brian J. Graham, Gary A. Minor
