How does an evaporative cooling system work?
In an evaporative cooling system, hot outside air is forced through wet cooling pads by means of a motor-driven fan. The cooling pads are moistened continuously by a water pump that delivers water to the cooling pads. The cooled down air is then blown into the building.
Does evaporative cooling use outside air?
Evaporative cooling uses evaporation to help cool the air. Based on the principles of evaporation, hot and dry outside air is drawn through water-soaked cooling pads. As the air is pushed through these pads, the water evaporates and the heat in the air is absorbed, which lowers the air temperature.
How do I make my evaporative cooler colder?
10 Tips to Make Your Swamp Cooler Colder and More Efficient
- Use Your Swamp Cooler in a Dry Climate.
- Use Your Swamp Cooler Seasonally.
- Open the Windows.
- Run a Dehumidifier.
- Cultivate a Green Thumb.
- Experiment With Positioning.
- Prime the Pads First.
- Use Cold Water.
How long does evaporative cooling take to work?
When you first start your evaporative cooler, it needs time for the cooling pads to fully absorb the water. Once they are wet, they more easily wick water from the tank to stay wet, but it can take up to 15 minutes for them to become saturated at the outset.
How do evaporative coolers save you money?
Based on consumer product surveys,evaporative cooling costs between 2 and 10 cents per kilowatt hour,as opposed to traditional cooling costs,which start at about 11 cents per kilowatt
Do evaporative cooling systems use too much water?
Evaporative coolers use a substantial amount of water , which could present a problem during times of drought. Depending on the severity of the drought and how much water your cooler uses, you may want to look into the following options: Install a thermostat and timer on your cooler so it only operates when necessary. Use a two-speed blow motor.
How effective are evaporative coolers?
The key to effectively cooling your home with an evaporative cooler is hot, dry air such as what is found in desert areas like the southwestern United States. In fact, evaporative coolers are most effective during the hottest times of the day and when humidity levels are below 60 percent.
Should I use an evaporative cooler?
Evaporative coolers work best in hot dry climates because the evaporation process cannot work if the outside air has too much moisture. Arid regions will have the most success when using an evaporative cooler because dry air is needed to pass through the wet pads of an evaporative cooler in order to cool the air.
