What is the required CFM for drying an area of 15120 CF using a desiccant dehu?

To determine the required cubic feet per minute (CFM) for drying an area of 15,120 cubic feet (CF), it's crucial to understand the relationship between the volume of the space being dried and the airflow needed for effective moisture removal using a desiccant dehumidifier.

Desiccant dehumidifiers typically operate by moving air through a drying medium that absorbs moisture. An industry standard for calculating the necessary airflow for effective drying is to have a CFM that allows the air in the space to be cycled multiple times within a certain timeframe, providing adequate moisture removal.

When calculating airflow requirements, the common metric is that 1 CFM is generally sufficient to dry about 100 CF of material effectively under ideal conditions. Using this standard, for a space of 15,120 CF, we can determine the required CFM by dividing the total volume by the capacity per CFM.

Doing the math:

15,120 CF ÷ 100 CF per CFM = 151.2 CFM.

For efficient drying, it is wise to increase this rate to allow for faster drying. A factor of about five times that figure may be applied to ensure air circulation is sufficient, which would suggest needing around 500 CFM
