Types of Evaporative Coolers
There are different types of evaporative coolers. Some fixed units blast air directly into the building, while others use duct systems to distribute air to numerous areas; some fixed units are moveable, while others must be anchored to the wall. Evaporative air cooler ducts, on the other hand, are frequently larger than conventional ducts, and using the incorrect duct system will reduce the performance of your air cooler. Knowing the circumstances of your home or business can help you choose the right cooler. Evaporative air coolers come in three varieties:
- Direct swamp coolers
- Indirect swamp coolers
- Mounted “draft” swamp coolers
Types of Evaporative Coolers
Direct evaporative air coolers
These machines, often known as swamp coolers, are undoubtedly the most cost-effective temperature control method. They’re cheap to run, need little upkeep, and are generally portable enough to take wherever you choose. There’s also no need for setup: they’re ready to use right out of the box; plug them in and fill the reservoir with water.
On a hot, dry day, these devices employ the natural cooling qualities of water vapor to reduce the air temperature in your shop by as much as 26°F. Warm air from the outside enters the evaporative media pad, where it is trapped; as waterfalls through the pad, air molecules are cooled by evaporation. A substantial 30″ diameter fan pushes wet (but still dry) air across the industrial space.
Indirect evaporative air coolers
Because they don’t add humidity to the air, these coolers don’t swamp coolers. They aren’t even transportable. Indirect cooling, on the other hand, allows industrial buildings, restaurants, and other companies to chill their areas at lower temperatures than portable swamp coolers like the Cool Boss. One thing that all evaporative coolers have in common is that the hotter the outside air is, the better the device functions. Indirect coolers make use of a secondary air source that can be heated before entering the evaporative media pad. Simply put, two air sources can be mixed, heated, and chilled through one or two stages of evaporation.
Mounted coolers
Direct and indirect coolers share several characteristics. Direct air coolers can be mounted or portable, whereas indirect air coolers must be mounted. An evaporative air cooler can be installed on the floor, a windowsill, or the roof.
Ground-mounting
The least frequent way for placing air coolers is ground-mounting; because cold air falls and hot air rises, there is less circulation of cool air if it is created close to the ground.
Window-mounting
For smaller rooms and work areas, window mounting is a common choice. A window-mounted air cooler will always have access to a source of fresh air.
Roof-mounting
Roof-mounted evaporative air coolers are prevalent in commercial and industrial settings, but not in most individual homes. Air ducts are required for these units, and they are more likely to require costly maintenance over time. However, installation is simple, especially if the building already has the necessary air ducts.
Air coolers are far less expensive to run than air conditioners, whether you’re searching for a portable evaporative air cooler (also known as a swamp cooler) or a more permanent alternative.
