Calculation Formula

Air Changes per Hour (ACH) = Air Flow Rate / Room Volume

Where:
Air Changes per Hour (ACH) is the number of times the air in the room is completely replaced with fresh air in an hour.
Air Flow Rate is the rate at which fresh air is supplied to the room in cubic meters per hour.
Room Volume is the volume of the room in cubic meters.

Learn how to use the Air Exchange Calculator Air Change Per Hour Minute calculator and its working principles

How to Use the Calculator

  1. Enter the volume of the room in cubic meters in the "Room Volume" field.
  2. Enter the air flow rate in cubic meters per hour in the "Air Flow Rate" field.
  3. Click the "Calculate" button to compute the air changes per hour and per minute.
  4. The results will be displayed in the respective fields.

Understanding the Results

The calculator provides two results:

  • Air Changes per Hour (ACH): The number of times the air in the room is completely replaced with fresh air in an hour.
  • Air Changes per Minute (ACH/min): The number of times the air in the room is completely replaced with fresh air in a minute.

Example

If a room has a volume of 50 cubic meters and the air flow rate is 100 cubic meters per hour, the calculator will show:

  • Air Changes per Hour (ACH): 2.00
  • Air Changes per Minute (ACH/min): 0.033

This means that the air in the room is completely replaced with fresh air 2 times in an hour, or approximately every 30 minutes.
