Welcome to our comprehensive guide on the Negative Air Machine Calculator. This calculator, a valuable tool in the environmental science and health sectors, enables users to calculate the required airflow rate for a negative air machine in a specific room.
Definition of a Negative Air Machine
A Negative Air Machine, commonly referred to as an air scrubber, is a device used to eliminate contaminants, particles, and airborne pollutants from the air in a confined space. The effectiveness of this machine is measured by the Clean Air Delivery Rate (CADR), which is calculated based on the room volume and desired Air Changes per Hour (ACH).
How the Negative Air Machine Calculator Works
The Negative Air Machine Calculator uses a simple formula to determine the required airflow rate. Users input the room's volume in cubic feet and the desired Air Changes per Hour (ACH). Once these parameters are entered, the calculator provides the necessary airflow rate in Cubic Feet per Minute (CFM), a measure of the volume of air cycled through the room each minute.
The Mathematical Formula behind the Calculator
The formula used by the Negative Air Machine Calculator is:
Required Airflow Rate (CFM) = Room Volume (cubic feet) x Air Changes per Hour (ACH)
In this formula, 'Room Volume' represents the total space needing air purification, calculated by multiplying the room's length, width, and height. 'Air Changes per Hour (ACH)' is the number of times the air within a space is replaced per hour.
An Example of How to Use the Calculator
Let's assume we have a room measuring 10x10x10 feet, which gives us a room volume of 1,000 cubic feet. We desire 6 Air Changes per Hour for a general air cleaning process. By plugging these numbers into the formula, we get a Required Airflow Rate of 6,000 CFM.
