Exhaust Air Grille Velocity at Gail Ingram blog

Exhaust Air Grille Velocity. Air velocity is a critical factor in return air grille sizing. The goal of stack design is to specify the minimum flow of the exhaust system, exhaust velocity, and stack height that ensures. Recommended air velocities in hvac ducts. 551 cfm for a stamped face grille! Neglecting to consider the desired air velocity is a common oversight that can impact both comfort and system performance. Air velocity at a distance of approximately 2,5cm from the grille is known as the air exit velocity vc (m/s). The duct velocity in air condition and ventilation systems should not exceed certain limits to avoid unnecessary noise generation and pressure. When calculating pressure drop for return or exhaust systems, remember to include 1 velocity head to accelerate still air in the room to duct velocity. To ensure the noise created by the grille is acceptable, it is recommend to use a face velocity of 500 fpm when sizing a return air grille. Flow velocity in air ducts should be kept within certain limits to avoid noise and unacceptable friction. Under the regulation followed in this study and shown in the above figure, the maximum velocity in forming the boundary of the range and diffusion is 0.5m/s. If the grille can’t fit due to limited space, you can allow the face velocity to go higher but the maximum face velocity i would recommend is 800 fpm. The system would have been much quieter and had a lower.
