Evaporative Cooler CFM Calculator

The Evaporative Cooler CFM (Cubic Feet per Minute) Calculator is a tool used to estimate the required airflow rate for an evaporative cooler in a given space. This calculator takes into account several factors to determine the necessary CFM to achieve effective cooling. Here’s an explanation of the formula used in this calculator:

1. Square Footage of Room (TA): This is the total floor area of the room or space where you want to use the evaporative cooler, measured in square feet (ft²).
2. Ceiling Height (CH): This represents the height of the room’s ceiling, measured in feet (ft).
3. Air Exchanges Per Hour (AE): Air exchanges per hour refer to the number of times the air in the room should be exchanged with fresh air in one hour. This value is usually specified based on the desired ventilation and cooling requirements.
4. Evaporative Cooler CFM (CFM): This is the calculated airflow rate needed for the evaporative cooler to achieve the desired air exchanges and cooling effect, measured in cubic feet per minute (ft³/min).

The formula for calculating the required Evaporative Cooler CFM is as follows:

CFM=TA∗CH∗AE/60

In this formula:

• We multiply the Square Footage of Room (TA) by the Ceiling Height (CH) and the Air Exchanges Per Hour (AE).
• We then divide the result by 60 to convert the units to cubic feet per minute (ft³/min), which is a common measure of airflow rate.

The Evaporative Cooler CFM Calculator helps determine the appropriate CFM rating for an evaporative cooler to ensure efficient cooling and ventilation in a specific room or space, taking into account its size and air exchange requirements.
