Why is airflow measurement important in HVAC systems?

• A. It increases electrical consumption
• B. It ensures efficient operation and indoor air quality
• C. It prevents the system from running
• D. It adjusts the height of the HVAC installation

Answer: (B)

Airflow measurement is critical in HVAC systems primarily because it ensures efficient operation and maintains indoor air quality. Proper airflow measurement allows technicians to assess whether the system is delivering the correct volume of air to various spaces. If airflow is insufficient, it can lead to discomfort, reduced heating or cooling effectiveness, and even potential health issues due to poor ventilation. Moreover, measuring airflow helps in balancing the system, ensuring that each zone receives an appropriate amount of conditioned air. This not only enhances comfort but also promotes energy efficiency, as systems operating under optimal conditions typically consume less energy. Additionally, proper airflow contributes to effective filtration and humidity control, which are essential for maintaining good indoor air quality. In contrast, other options address outcomes that may not directly relate to the purpose of airflow measurement, such as electrical consumption or system operation specifics that are not tied to airflow metrics.
