Have you ever stuck your finger in your mouth then held it up in the air? When the breeze hits it then your finger feels cool. This is the same concept as evaporative coolers, also known as “swamp coolers.”
In areas with low humidity, evaporating water into the air gives an energy efficient and productive method for cooling down your home. The machine to do this is called an evaporative cooler. The cooler can take the ambient air 15°-to 40°F cooler and drives the hotter air out through open windows.
Another excellent benefit is that evaporative coolers use about a quarter of the energy to run and a half of the cost of air conditioners to install. You will need to keep up on maintenance with the evaporative coolers and will only work in low humidity areas.
Evaporative systems are very competitive in terms of first cost and provide significant reductions in operating energy use, as
well as peak-load reduction benefits – US Dept. of Energy
There are two choices for installing your evaporative cooler. First, the cooler can blow into the building at a central location. The air is then forced into the ductwork pushing the air into all the rooms of a home.
Small, portable and small coolers on wheels are available as well. Although portability is an advantage, the cooling is restricted to just one room. This means the cooling effect will be very small and limited.
Windows should always be open in your home. Or you can have an up duct that also can allow the warm air to be pushed out of the room. The benefit here is that fresh air is always being pushed into the house, unlike with an air conditioner, which merely recirculates.
You can regulate both temperature and humidity by opening windows in the areas you want to cool, and closing windows in unoccupied areas. Where open windows create a security issue, install up-ducts in the ceiling. Up-ducts open to exhaust warm air into the attic as cooler air comes in from the evaporative cooler. Evaporative coolers installed with up-ducts will need additional attic ventilation.
You can control the air movement of the evaporative cooler by adjusting window openings. Try experimenting by opening different windows to find what is good for you. Remember, if you open the windows too much then hot air will come thru from the outside. Humidity will build up with closed window.
Save yourself a lot of work and money by draining and cleaning your evaporative cooler regularly. The sediment that builds up inside your cooler must be removed periodically. you have to check the filters, pads, pump, and reservoir when the cooler is, being used the most. Replace the pads at least twice during the cooling season, or as often as once a month during continuous operation.
