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.
Claims21
1-20. (canceled)
An air diffuser, comprising:
- a circulation inlet;
- a mixing chamber defining a mixing region;
- a room air intake fluidly coupled with the mixing region via the circulation inlet;
- a nozzle configured to accelerate a conditioned air flow in a direction and into the mixing region such that the conditioned air flow induces unconditioned room air to enter the mixing region through the circulation inlet and from the room air intake;
- a blank-off assembly defining a side of the mixing chamber;
- and
- a plate extending at an oblique angle relative to the direction, wherein the plate and the blank-off assembly define a mixed air outlet configured to output a mixture of the conditioned air flow and the unconditioned room air from the mixing region.
An air diffuser, comprising:
- a wall;
- a blank-off assembly opposing the wall;
- a mixing region between the wall and the blank-off assembly;
- a nozzle configured to accelerate a conditioned air flow into the mixing region such that the conditioned air flow induces unconditioned room air to enter the mixing region from a room air intake;
- and
- a plate extending at an oblique angle relative to the wall, wherein the plate and the blank-off assembly define a mixed air outlet configured to output a mixture of the conditioned air flow and the unconditioned room air from the mixing region.
An air diffuser, comprising:
- a circulation inlet including a first dimension extending in a direction;
- a mixing chamber defining a mixing region;
- a room air intake fluidly coupled with the mixing region via the circulation inlet;
- a nozzle configured to accelerate a conditioned air flow into the mixing region such that the conditioned air flow induces unconditioned room air to enter the mixing region through the circulation inlet and from the room air intake;
- a blank-off assembly defining a side of the mixing chamber, wherein the blank-off assembly comprises a second dimension extending in the direction, and a ratio between the first dimension and the second dimension is between 1:2 and 1:5;
- and
- a mixed air outlet configured to output a mixture of the conditioned air flow and the unconditioned room air from the mixing region, wherein the mixed air outlet is defined by a portion of the blank-off assembly and a plate of the air diffuser.
