High-volume HVLS stands for high-velocity low-speed fans. These fans have a diameter greater than seven feet and are often suspended straight from the ceiling or down-red if the ceiling is fairly high. As the name says, these fans travel slowly, with a maximum speed of 200 RPM and a speed of less than 60 MPH at the fan blade tip. Another requirement is that at least 500 cubic feet of air pass through the fan in one cycle.
HVLS fans are a recent innovation in the fan market that provides numerous benefits that a standard ceiling fan does not. Super Fans is an HVLS fan supplier in Singapore where you can learn more about its benefits and applications. HVLS supporters have been seen in local gyms, ballparks or stadiums, and airport terminals. HVLS fans are enormous, slow-moving fans that quietly circulate air, and we’ll look at them in more detail in this post. We’ll go through how HVLS fans work, where they may be utilized, and some of the other benefits of using them.
How Do HVLS Fans Operate?
Cool air passes over the body, breaking up the moisture-saturated boundary layer and speeding up evaporation to provide cooling effects. When ceiling fans turn, they form an air column. This column of air rushes down and out of the floor. A horizontal floor jet is a deep wall of horizontally flowing air that is proportionate to the fan’s diameter and, to a lesser extent, speed. When the floor jet has reached its full capacity, it will move outward until it comes into contact with a vertical surface, such as a sidewall.
Under ideal conditions, an 8-foot (2.4-meter) diameter fan produces a 36-inch (910-mm) deep floor jet.
A fan with a diameter of 24 feet (7.3 meters) produces a floor jet 108 inches (2,700 mm) deep, tall enough to encircle a human standing on the floor or a cow, which was the original development target.
When the descending air column of an HVLS fan hits the floor, the air spins horizontally away from the column in all directions. The air that travels outward is referred to as the “horizontal floor jet.” Because the height of the floor jet is determined by the diameter of the air column, a bigger diameter fan creates a larger air column and hence a higher floor jet. Smaller high-speed fans with the same displacement cannot produce the same results. The power needed to drive a fan increases roughly proportionally to the cube of the fan’s usual airspeed.
A commercial fan that moves air at 20 mph (miles per hour) consumes 64 times the energy of a fan that moves air at 5 mph (miles per hour). Airspeed combined with fan “efficiency” implies that extremely large, low-speed commercial fans are more efficient and effective than small high-speed fans when it comes to cooling humans or animals.
What Services Can HVLS Fans Offer?
HVLS fans are ideal for applications where equipment or obstructions may prevent optimal airflow from a wall or floor fan. Because fans are frequently located near the ceiling, the air column avoids equipment in order to reach humans or livestock.
HVLS fans promote comfort by evenly distributing temperatures in the winter and keeping employees cool in the summer without the need for frequent modifications to the HVLS equipment.
An HVLS fan saves energy because it has bigger props to move more air without needing more electricity to increase speed. The low-power nature of HVLS ceiling fans ensures that a building will not have to expend excessive energy to run the equipment while yet delivering appropriate ventilation.
Furthermore, HVLS supporters advocate for improved health and wellness. Controlling humidity and moisture can help to prevent bacteria buildup on damp surfaces. By decreasing condensation and drying off moisture, continuous air circulation prevents slippery flooring. An HVLS fan can also be used to pull contaminants from space and out of a structure or to provide fresh air into a polluted area.
