What is the purpose of measuring air velocity in relation to effective temperature?

To enhance heating efficiency
To improve moisture retention
To analyze comfort levels
To regulate air pressure

The correct answer is: To analyze comfort levels

Measuring air velocity is crucial for analyzing comfort levels in indoor environments. Effective temperature is not just determined by air temperature alone; it also takes into account the velocity of air movement, which influences how individuals perceive temperature. Higher air velocities can enhance the body's heat loss through convection, making a room feel cooler than the actual air temperature. This knowledge enables HVAC professionals to optimize airflow for maximum comfort, ensuring that spaces do not become too warm or too cool for occupants. Understanding the interplay between air velocity and comfort helps in designing systems that maintain a pleasant indoor climate, which is essential for occupant satisfaction and productivity.
