The noisy manner in which HVAC systems perform can often lead to a great deal of distraction in the workplace. As inventors of high volume, low speed (HVLS) fans, MacroAir, implemented a cooling solution that delivers on performance without creating its own disturbance. HVLS fans are not only energy efficient, but also much more conducive to a quieter work environment than the HVAC systems.
HVLS commercial ceiling fans start off powerfully and smoothly and continue to operate in that smooth quiet manner. HVAC systems, on the other hand, start off and continue to operate in a noisy manner, at random points during the day, as air pushes through the vents. The noise from the system and vents produces a less than desirable working environment as it disrupts phone calls and causes people to speak at higher decibels. This in turn creates even more noise which can be irritating to the ear.
How MacroAir HVLS Commercial Ceiling Fans Work
MacroAir HVLS commercial ceiling fans were designed to move large volumes of air in a gentle manner. HVLS fans remove heat through thermal destratification as they push the heat down. The air moves downward and out traveling along the floor cooling the entire building from top to bottom. In fact, under ideal conditions, an 8-foot fan produces a floor jet of air approximately 36 inches deep.
The manner in which these large slow-moving MacroAir fans operate, differs from that of the standard 36-inch high-speed ceiling fan. HVLS fans differ from residential ceiling fans with regard to diameter, rotational speed, performance and are more energy efficient. MacroAir’s smallest HVLS fan is 8-feet in diameter while the largest has a diameter of 24 feet.
So What About HVAC Systems?
HVAC systems were not created to move air but to cool air and are also expensive. Large industrial facilities or commercial spaces will require larger systems, more units and the addition of extra ducting which means higher costs. HVLS fans are often used to supplement HVAC systems as they provide a strong cooling effect while helping to maintain a constant temperature and will help save energy costs.
Director of Energy and Engineering Services at H.T. Lyons, Scott Sine successfully used HVLS fans to support the HVAC system he installed in a warehouse. He noted that HVLS fans help to achieve the following:
- Ventilation effectiveness
- Lower energy consumption
- Evaporative cooling
- Thermal mass
- Optimized compressor staging
He also noted that during the winter, HVLS commercial fans reverse their sequence. During the winter HVLS fans help to reduce heating cost by pulling warm air from the ceiling down to the floor. The added benefits of HVLS fans outweigh those of AC system by far and noted two huge benefits:
- Reduced cost
- Less noise in the work environment
MacroAir 6ixBlade™ HVLS fans are deceptive. The fans operate slowly, smoothly and quietly so that you may even forget that they are there. The same cannot be said about the HVAC systems. Those who have to work in a building outfitted with HVLS fans will certainly appreciate its smooth consistent performance as opposed to the intrusive noisy performance of HVAC system.
