Evaporative cooling is a method of heating that has been used for thousands of years. Though it has undergone some technological advances, it still offers a number of advantages today. Should you choose this commercial cooling method over refrigerated cooling options such as commercial heat pump and rooftop systems?
The Advantages of Evaporative Coolers
Evaporative coolers offer significant benefits compared to more common refrigerated systems.
- Fresh, clean air
They are supplied by 100% fresh outdoor air – a boon in the coronavirus era where ventilation and the circulation of fresh air are integral to reducing the concentration of virus particles in indoor air. These systems do not circulate air but displace indoor air with fresh outdoor air every few minutes, filtering it through the systems cooling pads, which also removes pollutants and allergens.
- Unparalleled efficiency
Modern evaporative cooling technology could save you up to 80% on energy costs compared to traditional heat pump systems.
- Quiet performance
Evaporative coolers have a reputation for nearly silent operation.
- Environmentally friendly
Because these systems use far less energy than refrigerated systems, reduce fossil fuel use and your carbon footprint. They also use no synthetic refrigerants, requiring only a small amount of water for operation, like you might use for a shower.
- A leaky building envelope won’t affect performance
If your employees or customers frequently leave your doors open – not to worry. One of the great advantages of these systems is that this scenario will not impact system performance.
- Maintenance is a breeze
Care for your cooler by cleaning it twice a month with warm water and mild detergent, and occasionally wiping the outdoor unit with a damp cloth. When your system is not in use, store it according to manufacturer instructions until next season without worry.
How Evaporative Cooling Technology Works
Evaporative coolers feature a big, box-like frame that houses a large fan surrounded by water-wetted pads. The system draws in hot air, cooling it by blowing it through the wet filter pad using the process of evaporation – the transition of water from liquid to vapor. These systems sometimes referred to as “swamp coolers,” are common in the southwest. They work best in hot, dry climates and are typically located on the roof, like split systems and commercial rooftop units, which gives them the ample clearance they need for optimal performance.
Affordable, Convenient Cooling
Despite the longstanding history of evaporative cooling technology, today’s systems are far from primitive. In addition to LCD control panels, a programmable timer, remote control, and smart operation options are also available. These systems offer humidifier only mode to increase comfort on dry days, as well as fan-only mode and ionizing options to meet the comfort and health needs of your business.
