How To Operate A Swamp Cooler Locate the swamp cooler control — The swamp cooler control is a panel like any of the types of controllers pictured below. There are also several variations of these as well. See examples below. A New Mexico Tech Answers. After there is enough water in the bottom of the evaporative cooler, the pump begins to pull water through the water distribution lines. These water distribution lines are located at the top of the evaporative pads and pour water through them. After the evaporative pads have water on them, the blower motor begins pulling warm air into the swamp cooler, through the pads.
As the warm air goes through the pads, the moisture cools the air, and cleans it. This process is called evaporative cooling. This works the same way when you are exercising, and sweat, and then have a fan blow on you, cooling your skin. After the air is pulled through the evaporative pads and cooled, the blower takes the cooled air and forces it through the ductwork and vent, and into the house. Unfortunately, each of these parts of a swamp cooler has a lifespan; they don't last forever. Eventually, the mechanical parts of your evaporative cooler will get worn out and fail.
When this happens, make sure your home is covered by a home warranty. When something breaks down, you pay a small service call fee for it to be repaired and replaced, provided it failed from normal wear and tear and is covered under the home warranty contract.

Well it is necessary to understand something about the properties of heat, air and water vapour. The most common type of Evaporative Cooler is the Direct type, in which the hot outside air is cooled within the machine and forced into the building and exhausted to outside again.
Other types are Indirect type and Air Washer type. In this excellent article, Cristina Piattelli from Seeley international talks about direct evaporative cooling;. For example, it is the heat from the hot pavement that is given up to evaporate the water after a summer rainstorm, or the heat from the stove burner given up to evaporate the water in a boiling kettle. Evaporative Cooling is only possible because of this natural phenomenon of Latent Heat. It comes from surrounding air and materials.
Whenever a substance changes its state from solid to liquid ice to water and from liquid to vapour water to vapour or water to steam , it absorbs heat from the surroundings. 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.
Optional filters remove most of the dust from incoming air -- an attractive option for homeowners concerned about allergies. Filters can also reduce the tendency of some coolers to pull water droplets from the pads into the blades of the fan.
Most evaporative coolers do not have air filters as original equipment, but they can be fitted to the cooler during or after installation. Save yourself a lot of work and money by draining and cleaning your evaporative cooler regularly. Build-up of sediment and minerals should be regularly removed. Evaporative coolers need a major cleaning every season, and may need routine maintenance several times during the cooling season.
The more a cooler operates, the more maintenance it will need. In hot climates where the cooler operates much of the time, look at the pads, filters, reservoir, and pump at least once a month.
Replace the pads at least twice during the cooling season, or as often as once a month during continuous operation. Some paper and synthetic cooler pads can be cleaned with soap and water or a weak acid according to manufacturer's instructions. Filters should be cleaned when the pads are changed or cleaned. Be sure to disconnect the electricity to the unit before servicing it. Two-stage evaporative coolers are newer and even more efficient.
