HAVC Ventilation Grille

HAVC Ventilation Grille

1. Description

HVAC (Heating, Ventilation, and Air Conditioning) ventilation grille, also known as an air grille or air diffuser, is a component used in HVAC systems to control and direct the flow of air within a space. It is typically installed in walls, ceilings, or floors and serves various purposes, such as distributing conditioned air, maintaining air quality, and providing thermal comfort.

The primary function of an HVAC ventilation grille is to allow air to enter or exit a room while ensuring proper airflow distribution. It helps regulate the movement of air from the HVAC system into the desired areas and helps control the velocity, direction, and spread of air within the space.

2. Main Types

Supply Grilles: These grilles are designed to distribute conditioned air from the HVAC system into a room or space. They typically have adjustable louvers or dampers to control the direction and volume of airflow.

Return Grilles: Return grilles are responsible for collecting and returning air back to the HVAC system for reconditioning. They often have larger openings and are positioned on walls or ceilings to draw in air from the room.

Ceiling Diffusers: Ceiling diffusers are mounted on the ceiling and are used to distribute air evenly across the room. They typically feature multiple small openings or slots to diffuse the air in various directions.

Floor Grilles: Floor grilles are installed in the floor and are used for supply or return air purposes. They are commonly used in spaces where air intake or exhaust near the floor level is necessary.

Wall Grilles: Wall grilles are mounted on walls and are often used for supply air distribution. They can be designed with adjustable blades or louvers to control the airflow direction.
