According to the code, how should air supplies be adjusted?

The adjustment of air supplies according to the code should be done evenly to ensure optimal performance and efficiency of the HVAC system. This approach helps maintain balanced airflow throughout the space, promoting proper ventilation and comfort levels. Uniform air distribution prevents areas of excessive heat or cold and supports the overall functionality of the heating and cooling systems.

When air supplies are adjusted evenly, it allows for consistent temperatures and better humidity control in all parts of a building. This is critical for not only occupant comfort but also for the system's energy efficiency. Systems that are not well-balanced can lead to increased energy consumption and can reduce the lifespan of equipment due to strain from uneven loading.

Adjusting air supplies randomly, occasionally, or irregularly can lead to uneven temperatures, draft issues, and even contribute to compliance problems with building codes, as proper ventilation is mandated for safety and health standards. Therefore, even, deliberate adjustments in accordance with the code are essential for achieving reliable and efficient HVAC system operation.
