How many desiccant dehumidifiers are needed for an affected area of 15120 CF if each is rated at 385 CFM?

To determine how many desiccant dehumidifiers are needed for an affected area of 15,120 cubic feet (CF) with each dehumidifier rated at 385 cubic feet per minute (CFM), you first need to calculate the required total air movement.

The basic principle involves understanding the relationship between volume, air exchange rate, and the capability of each dehumidifier. For effective drying, you will often need to ensure that the air within the affected space is exchanged a certain number of times per hour. In many drying scenarios, exchanging the air at least once per hour can be a reasonable estimate for effective moisture removal.

1. Conversion of volume to CFM needs: First, you convert 15,120 CF into CFM for hourly exchange:

[

\text{Required CFM} = \frac{\text{Volume in CF}}{\text{Total hours desired for drying}}

]

Assuming a target of 1 air exchange per hour, the required CFM is the same as the volume:

[

\text{Required CFM} = 15,120 \text{ CF}

]

2. Calculating dehumidifiers needed: Next, you take
