Determine Airflow (CFM) and Static Pressure
Airflow Calculation Basics
You need to know how much air your system must move to keep equipment cool. Start by following these steps to calculate the required airflow:
- Find out how much heat your system produces. Use the formula: q = mCp ΔT, where q is the heat to remove, m is the mass of air, Cp is the specific heat, and ΔT is the temperature rise allowed.
- Calculate the rate of cooling needed. Divide the total heat by the time over which you want to remove it.
- Use the cooling power formula to find the airflow rate: ṁ = Q̇/(1.0746 × ΔT). This gives you the airflow in cubic feet per minute (CFM).
- Adjust your result for real-world conditions by applying a service factor. This ensures your fan can handle unexpected changes or extra heat.
Always round up your airflow needs to add a safety margin.
Understanding System Impedance
You must consider system impedance when selecting a cooling fan. System impedance is the total resistance air faces as it moves through your equipment. Ducts, filters, and bends all add to this resistance. Static pressure measures how much force the fan needs to push air through these obstacles.
If you ignore system impedance, your fan may not deliver enough airflow. This can cause overheating or even damage your system. Compare your system’s resistance curve with the fan’s performance curve. Make sure the fan can overcome the pressure drop from the inlet to the exhaust.
Matching Fan Performance to Application
You want your fan to fit your application perfectly. Follow these best practices:
