HVLS Fans: How Low Speed Makes Them More Efficient

In recent years, the popularity of High Volume Low Speed (HVLS) fans has risen dramatically among industrial businesses, particularly those for whom temperature and climate control are important requirements. In addition to optimizing the airflow in your space, an HVLS fan will also help you make significant savings on energy costs.
How Do They Work?
HVLS fans work in quite a simple manner. Their long lightweight blades gently push large amounts of air downwards, where it travels along horizontally along the floor. This process keeps the air moving around the room in a circular motion at a stable speed, and prevents pockets of air sitting stagnant.
Low Speed Airflow Benefits
The primary advantage of keeping air moving at a slow speed is that it’s non-disruptive and the airflow optimization achieved is much greater compared to conventional high speed floor fans. Also, when large volumes of air are circulated around the room, it effectively counteracts the ‘rising heat’ effect, and maintains a uniform room temperature. In large, cavernous spaces, HVLS fans can potentially reduce the temperature from 7 to 11 °F .
Energy Efficiency
HVLS fans work in combination with HVAC systems or the natural ventilation. However, while HVAC systems are efficient at distributing air, they’re not good at mixing it. Since warm air rises, there can be a difference of up to 20 °F between the ceiling and the floor in tall, cavernous facilities. HVAC units often work extra hard to make up for this difference, which leads to a wastage of precious energy.
As we mentioned above, an HVLS fan allows constant circulation of air, which mixes air and removes the different layers of temperature from within it. This process is known as “destratification” , and it reduces the load on the HVAC systems, which naturally leads to lower energy consumption.
Selecting the Right HVLS Fans for Your Facility
When shopping for HVLS fans, it’s important to remember that not all products are the same. Owing to the drastic rise in demand, manufacturers of HVLS fans now offer products in a variety of sizes and specification, which means that you can now buy HVLS fans that are designed to optimize airflow to your specific requirements. So analyze the needs of your facility before you make a buying decision.
