Abstract: 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.

Abstract: A chilled beam includes a body having a first side and a second side opposite to the first side. The chilled beam also includes a first mounting bracket coupled to the first side and configured to rotate against a first bias of the first mounting bracket in response to a first force against the first mounting bracket. The chilled beam also includes a second mounting bracket coupled to the second side and configured to rotate against a second bias of the second mounting bracket in response to a second force against the second mounting bracket.

Abstract: An air diffuser configured to be positioned in a raised floor, in which the air diffuser includes a sleeve having a first end and a second end with an air flow passage extending through the sleeve from the first end to the second end, a diffuser face disposed at the first end of the sleeve and configured to be exposed to an environment in an installed position within the raised floor, a damper disposed at the second end of the sleeve, and a plenum chamber defined within the sleeve between the damper and the diffuser face.

Abstract: A linear bar diffuser includes a grille frame and blades in a stacked arrangement within the grille frame such that space is provided between adjacent blades to facilitate flow of an incoming air flow therethrough. One of the blades includes a leading edge configured to face the incoming air flow, the leading edge including an undulated contour extending along a length of the blade and into a width of the blade, the width of the blade extending transverse to the length and between the leading edge and a trailing edge of the blade.

Abstract: A plenum slot diffuser is configured to receive an air flow and includes a blade configured to guide the air flow toward a space to condition the space. The blade includes a length along which a leading edge of the blade extends, where the leading edge is configured to face an air flow. The blade also includes a width extending transverse to the length between the leading edge and a trailing edge of the blade, and including a curved profile extending along a majority of the width. The blade also includes an undulated contour extending along the leading edge and into and out of the width.

Abstract: A round or rectangular ceiling diffuser includes a blade. The blade includes a leading edge configured to face an incoming air flow and having an undulated contour extending along a closed-loop formed by the blade. The blade also includes a trailing edge opposite to the leading edge, where a width of the blade extends from the leading edge to the trailing edge and the undulated contour extends into and out of the width.

Abstract: A variable air volume diffuser and method of operation are disclosed. The system includes an energy harvesting device, a ring-shaped damper and a frame adapted to interface with the ring-shaped damper, wherein the ring-shaped damper is driven by energy harvested from the energy harvesting device.
