True or False: A return grille allows the user to modulate the air flow.

True or False: A return grille allows the user to modulate the air flow.

• A. True
• B. False
• C. Depends on the model
• D. Only in certain climates

Answer: (B)

A return grille primarily serves as an inlet for air that has circulated through a space to return to the HVAC system for reconditioning. This component typically does not have the capability to modulate air flow on its own; its main function is to facilitate the return of air to the system. The modulation of airflow depends on other components, such as dampers or variable air volume (VAV) systems, which can adjust the flow of air based on demand or specific needs. Thus, stating that a return grille allows for air flow modulation is inaccurate, making the answer false.
