Calculate Air Exchange Rate



Formula

The formula to calculate the Air Exchange Rate (AER) is:

\[ AER = \frac{Q}{V} \]

Where:

Air Exchange Definition

Air exchange is defined as the rate of change of units of air moving through a given volume at any time. Typically, this is in reference to the number of air changes per time for a room or indoor area. This helps determine the ventilation of the area.

Example Calculation

Let's consider an example:

Using the formula to calculate the Air Exchange Rate:

\[ AER = \frac{500}{10000} = 0.05 \, \text{exchanges per minute} \]

This demonstrates that with a Q of 500 ft³/min and a V of 10,000 ft³, the air exchange rate would be 0.05 exchanges per minute.
