What is the minimum required distance a diffuser must be from all windows, doors, and building openings?

The minimum required distance a diffuser must be from all windows, doors, and building openings is established to ensure proper air distribution and to prevent air contamination from outside sources. This distance helps to avoid the reintroduction of pollutants, odors, and environmental contaminants that may enter through openings when the air is drawn in for ventilation or air conditioning purposes.

In this context, a distance of 7.6 meters is defined as a standard to create a buffer zone. This allows for efficient airflow while maintaining comfort and indoor air quality. By positioning diffusers at this minimum distance, the design minimizes the chances of negative impacts on the occupied space, such as fluctuating temperatures or the mixing of conditioned and unconditioned air.

Maintaining this standard supports both energy efficiency and occupant comfort, making it essential for HVAC designs and installations. Proper adherence to these guidelines is crucial for achieving optimal performance in ventilation systems.
