1. The Difference Between Air Supply and Exhaust Outlets
Air supply and exhaust outlets serve distinct purposes in ventilation systems. The air supply outlet, typically located at the end of an air conditioning or ventilation system, i.e. fan coil units, introduces fresh air into a room. In contrast, the exhaust outlet removes polluted or stale air from the indoor environment. These outlets differ not only in function but also in their placement and design.
2. Location of the Air Supply Outlet
The positioning of air supply outlets varies depending on the design of the ventilation or air conditioning system. They are commonly installed on ceilings, walls, or floors.
2.1. Ceiling and Floor Layout
Air supply outlets in this setup are usually located on the ceiling, delivering fresh air from above, while exhaust outlets are positioned closer to the floor to draw out polluted air below.
2.2. Side-to-Side Layout
In this arrangement, the air supply outlet is placed on one side of the room to introduce fresh air, while exhaust vents are located on the opposite side or lower in the room to remove indoor air efficiently.
2.3. Floor-Level Air Supply for Dust Control
For environments requiring air purification, such as laboratories or operating rooms, air supply outlets are often placed on the floor. These outlets deliver fresh air upwards, while exhaust vents on the ceiling or walls expel contaminated air.
3. How to Choose the Right Air Supply Outlet Position
Selecting the ideal location for an air supply outlet depends on various factors, including the room's layout, the ventilation system type, and its intended use. Generally, air supply and exhaust outlets should be installed in complementary positions to ensure optimal air circulation.
4. Conclusion
Air supply and exhaust outlets play unique roles in maintaining indoor air quality. The air supply outlet introduces fresh air into the space, while the exhaust outlet removes contaminated air. Their locations—whether on ceilings, walls, or floors—should be strategically chosen based on the room's layout, ventilation system, and purpose to ensure effective air circulation and comfort.
