Throttling plates and a pressure equalization chamber balance airflow through perforated walls to deliver uniform ventilation with lower noise.

A wavy trailing edge and spanwise blade slant homogenize outlet airflow, cut noise, and reduce stress at the main plate joint.

Shape memory alloy actuators let vent slats switch from parallel directional flow to diffuse airflow without complex mechanical control.

Heat recovery between fresh and return air cuts HVAC thermal load while controllable doors adapt cabin airflow to changing conditions.

Exterior wall chambers separate intake and exhaust airflow while absorbing and cancelling HVAC noise to reduce neighbor disturbance.

An invertible cup-shaped vent enables one-sided underroof mounting while maintaining airflow and a seal against water and insects.

A convex poppet surface and straighter nozzle path cut drag, flow separation, and turbulence, lowering valve noise by 4 to 5 dB.

Sealed cold/hot aisles and in-row cooling cut airflow overflow, improving modular data center cooling efficiency and deployment speed.

Mixed hot-exchange and non-hot-exchange airflow boosts circulation and sends gentler air downward for better room comfort.

Mixing non-heat-exchange air with conditioned air boosts indoor circulation and sends gentler airflow downward for better comfort.

A decreasing blade angle shifts negative pressure away from the front edge, cutting reflux flow and fan noise without extra blades.

A rectangular modular duct with insulation and flange joints improves fire containment, air capacity, and field installation without on-site welding.

Retaining tabs or recesses lock arcuate spring legs on a louver, easing assembly while preventing shaking, interference, and deformation in transport.
