Considering a Big Ass Fan? Will it actually help you stay cool?

ARE YOU TRYING TO FIND THE MOST EFFECTIVE WAY OF MOVING LARGE AMOUNTS OF AIR AND KEEPING A LARGE AREA COOL?

Big Ass Fans fill a gap in the market that many commercial fans cannot. They build incredibly big fans—no, seriously. They’re big. These HVLS (High-Volume, Low-Speed) fans are able to move huge quantities of air with minimal energy cost.

 The aptly-named Big Ass Fans can range from 2.4 metres to 4.3 metres in diameter (for their Essence range), providing a wide circumference of airflow. This is most useful for maximizing air distribution from HVAC (heating/ventilation/air conditioning) systems or to generate air movement in large commercial spaces that don’t have an alternative way of bringing air in from outside.

However, Bigass Fans don’t bring in fresh, cooler ambient air from the outside. Depending on what you need from a ventilation system, simply moving the same air around over and over inside a commercial space may not be the cooling effect you are after. The only cooling effect obtained by moving air around this way is a perceived effect for people who are working directly underneath the fan. The air passing around them will feel more comfortable. However, moving air around does not lower the temperature in the space.

So, what exactly does a Bigass Fan do?

A Bigass Fan operates like a more powerful roof fan. It circulates and evenly distributed the air within a room or space. That means that the indoor temperature will be the same everywhere in the room. In colder winter months, this ensures that any rising heat that gathers in the roof space is pushed back down into the living or working space. In summer, it evenly distributes the cooler indoor air.

Bigass Fans do not actively lower the temperature in a room. This is because the fan doesn’t actively push air out through openings like windows or roller doors. It does, however, circulate great quantities of airflow which helps to make workers or homeowners more comfortable.

Solar Whiz Pros:

1)    Market-Leading Airflow

Solar Whiz has been providing Australian & international markets with market-leading airflow for solar ventilators since 2009. We’ve serviced thousands of Australian homes with residential ventilators. Our growing commercial range has been sought out to cool a large variety of business schools and halls in the sizzling Aussie summers. Our SW-AU-C-155 units have, time and time again, made people in work and leisure environments cooler and more comfortable. You can check out some case studies here!

2)    Cooling Capacity

Solar Whiz units flush hot air out of localised spaces, using cooler, fresher air from outside. Heat builds up heat quickly in warehouses or factories that have large amounts of metal walls & roofing. A solar heat extractor like Solar Whiz removes hot air from rooms or roof spaces before it begins to build up and helps prevent excessive heat loads on the building.

3)    Flexible Installation & Accessories

Solar Whiz can be installed with a night operations/constant current kit that lets you run the unit after daylight hours. All you need to do is flick a power switch. We also offer options for controlling the temperature at which Solar Whiz starts operating. Our passionate team is well-practiced in creating powerful and effective solutions for businesses with unique ventilation problems.

4)    Cost Effective & Efficient Operation

Solar Whiz operates completely free of charge when the installation isn’t using night operations/constant current modules to assist your units. They’ll run when the sun is out—which is when you experience the hottest and most uncomfortable work and leisure conditions. If you pair it with night operations, this requires minimal amounts of electricity to run at full capacity. You’ll notice the difference in both comfort and cooling costs with a Solar Whiz.

Solar Whiz Cons:

1)    Doesn’t (Necessarily) Benefit HVAC Systems

Unless you’re using roof-space extraction methods, direct extraction from interior spaces can hinder cooling provided by HVAC or air-conditioning systems. The best use for Solar Whiz is to remove heat from large, hot spaces. This would be your home’s roof space or your warehouse/factory interior. This prevents heat-build from radiating through your ceiling.

Do I buy a Big Ass Fan? Or do I buy a Solar Whiz?

This depends on what you want out of your ventilation system. Bigass Fans might be for you if you want better overall airflow inside your property or evenly-distributed temperatures throughout a home or business. If you want to extract heat as soon as it begins to build up, Solar Whiz is the better option.

Also, consider installation cost as this can be very high for Bigass Fans systems due to the size and vibration of these very large units.
