The thickness of the air vent needs to be designed at around 4.5cm. In general, the width of the air conditioning outlet is around 15cm, and the length is between 60cm and 100cm.
When a single-layer louver vent is used for side supply of a full air conditioning system, its aerodynamic performance is slightly worse than that of a double-layer louver vent, and it is only used for general air conditioning engineering. I
