Note:

Air Changes per Hour (ACH) measures how many times the air in a space is replaced per hour. Higher ACH values indicate better ventilation, which is crucial for maintaining air quality.

Understanding the Parameters:

• Airflow Rate (Q): The amount of air supplied per minute, measured in cubic meters per minute (m³/min).
• Volume of Space (V): The total volume of the enclosed area, measured in cubic meters (m³).

Where is Air Changes per Hour Used?

ACH is widely used in various industries and applications, such as hospitals, laboratories, clean rooms, office spaces, and residential buildings. Proper ventilation is essential for ensuring good indoor air quality, reducing airborne contaminants, and maintaining comfort levels.
