Louvers, in the context of HVAC and ventilation systems, are adjustable slats or vanes used to control the flow of air or light. They are commonly installed in windows, doors, walls, and HVAC ducts to regulate the amount of air passing through. Louvers can be manually operated or automated, allowing for precise control over the ventilation and air distribution. In windows and doors, louvers provide adjustable ventilation and light control, allowing users to open or close them as needed. In HVAC systems, louvers are used as air intake or exhaust vents, providing a means to adjust the airflow direction and volume. Louvers play a crucial role in maintaining indoor comfort and air quality, offering versatility and practicality in various building applications.
