In our years of experience, one of the most frequently asked questions we get is – Do HVLS fans actually cool the air?
The short answer: yes, but not in the same way as traditional AC systems.
Namely, HVLS fans move large amounts of air and distribute it evenly in large, open spaces. In other words, they don’t refrigerate the air as an industrial air conditioner does.
But that doesn’t mean that HVLS fans don’t help with employee comfort. In fact, it’s quite the opposite!
When you understand the difference between HVLS fans and industrial air conditioners, you will know what kind of cooling strategy your space really needs.
HVLS fans are designed to move a lot of air at low speed. Their large blades create a broad column of air that moves downward before spreading across the floor and throughout the surrounding space.
With continuous circulation, HVLS fans prevent the air from becoming stagnant and improve the airflow throughout large industrial spaces.
Yes, moving air can make an area feel significantly cooler even without the temperature dropping.
When air moves across the skin, it helps moisture evaporate more quickly. This supports the body's natural cooling process and can reduce the sensation of heat. Naturally, this can be incredibly beneficial for employees who are constantly working on machines that generate a lot of heat.
As previously mentioned, HVLS fans don’t refrigerate the air but rather move it.
Industrial air conditioners, on the other hand, actively remove heat from indoor air and make it cooler.
With that said, if your facility requires consistent temperature control for production or other processes, an industrial AC system is a must.
However, keep in mind that these systems can be rather costly. On top of that, given the size of your facility, it may be challenging to cool the air evenly with AC alone.
For that reason, we suggest pairing your AC system with an HVLS fan. By improving air circulation, the fans can help distribute cooled air more effectively throughout the facility and reduce areas where warmer air tends to collect.
Yes, improved circulation can help reduce noticeable differences between warmer and cooler areas.
Warehouses often develop hot spots because of high ceilings, poor airflow, machinery, shelving, or open loading doors. An HVLS fan can help move air through these areas and create more consistent conditions across the occupied space.
In all cases, you must pay attention to fan placement. Structural features, storage racks, and other obstructions can all affect how the air is distributed.
If your facility has had issues with stagnant air and improper circulation, HVLS fans may be just what your space needs!
