Choosing the right air cooler for your industrial space is not just about picking the biggest machine available out there. If the capacity is too small, cooling will be weak; if it is too large, you might waste electricity, and even money. That’s why capacity circulation is one of the most important steps that you need to consider before installing a duct air cooler.
Why does capacity calculation matter?
Industrial spaces are very different from your homes or offices. You deal with large open areas, high ceilings, and heat-generating machines. Because of this, industrial cooling requires high air volume and not just low temperature. If you select the wrong capacity, cooling will feel uneven, and hot spots will remain. Proper circulation ensures comfort, productivity, and energy savings.
What does capacity mean in air duct coolers?
Duct air cooler capacity is mainly measured in air flow, not like air conditioners. The air flow is measured in cubic feet per minute. It tells you how much air the cooler can deliver every minute.
Measure your size
Start with accurate measurements. You need to measure the length and height of the space. The formula is area volume that is equal to length, width, and height.
Decide the required air changes per hour.
Air changes per hour and it means how many times fresh air should replace the air in this space every hour. Different industrial spaces need different values.
Calculate the required air flow
Once you know the volume and air changes per hour, you need to create the required air flow. It is volume multiplied by air changes per hour divided by 60.
Account for heat load
Industrial environments generate extra heat from machines and welding operations. If your area has heavy machinery, increase the air flow capacity by 10 to 30%, depending on the heat intensity.
Consider the ceiling height.
The height of your ceiling is very important. High ceiling strap hot air at the top. If your ceiling height is about 25 feet, you should increase the air flow capacity by another 10 to 15%.
Evaluate the occupancy load.
People generate heat, too. If your space has many workers or high movement activity, you can add additional air flow to the calculation to maintain comfort.
So calculating duct air cooler capacity might seem complex at first, but once you break it into steps, it becomes manageable. When you have created it properly, you can get better cooling preference and also lower electricity consumption. Instead of guessing, take time to measure and plan.
