If you live in dry climates, evaporative coolers are a great way to stay cool when the weather turns your home into an oven. Evaporative chillers are also much cheaper than conventional HFCs. Follow the directions in this article to keep your home cool with an evaporative cooler.

Steps

Method 1 of 3: Is an Evaporative Cooler Right for You?

  1. 1 Check the average humidity in your area. Evaporative coolers work best at very low relative humidity and high temperatures. If the average humidity in your area is around 40-50%, the evaporative cooler will not work as it should.
  2. 2 Check the water supply. The evaporative cooler will need a lot of water. As the name suggests, it works by evaporation, so you'll need a lot of water.
  3. 3 Appreciate ventilation in your home. Evaporative coolers will greatly increase the humidity in your home, so you'll need very good ventilation.Homes built for evaporative coolers will have air ducts, but for modern buildings it is best to open the windows. Your dad may have told you to close the windows to keep the coolness out, but when it comes to evaporative coolers, you need to do the opposite!

Method 2 of 3: How Many Evaporative Coolers Do You Need?

  1. 1 Calculate your CCM score. Evaporative coolers are classified according to the amount of air they can disperse and this amount is measured in cubic meters per second (CMR).
  2. 2 Use this formula to calculate the cooling rate for your home:
    • Determine the size of the area you want to cool.
    • Multiply this value by the height of the ceilings.
    • Divide this number by 120.
    • The result obtained will be the volume of the evaporative cooler that you need to take.
    • For example: The area of ​​your house is 140 m2, and the ceiling height is 3 meters:
      • 140m x 3m = 420 ÷ 120 = 3.5 CMR.
      • You need a cooler with a capacity of 3.5 cubic meters per second or more.

Method 3 of 3: Installing an Evaporative Cooler

  1. 1 Buy an evaporative cooler. Make sure its CCM power is right for you.
  2. 2 Install it. Different types of coolers are installed in different ways. Perhaps your house has a prepared place for installation, if so, install it there.
    • Evaporative coolers are best installed on the roof: after all, this is where the warm air is located. But you may have problems with installation, leakage or water supply.
    • Consider purchasing a portable evaporative cooler. There are portable vaporizers that attach to the wall or window.
    • Be sure to follow the manufacturer's instructions to maximize the power output of your chiller.
  3. 3 Create an “air vent” to direct cold air into the interior of the house. During the day, open the living room window a couple of centimeters and close the bedroom doors to cool only the used space. Close the living room windows at night and open one window in each bedroom you use. Do not open the windows all the way to direct cold air inward, preventing hot air from entering. Ventilation also prevents moisture build-up in the home, which not only impairs the efficiency of the cooler, but also prevents this moisture from damaging furniture, books, or musical instruments. This is because evaporative coolers use moisture to cool the air. If the humidity is too high, the temperature in the house will not change much.
  4. 4 Wait until it is 30 degrees Celsius or more outside the window. Believe it or not, evaporative coolers work best when it's warm outside. The evaporation mechanism is more efficient when there is a significant temperature difference between the cooling pads, water and air, provided the relative humidity outside the window is less than 30%.
  5. 5 Clean the filter regularly. A water filter for evaporative coolers removes all impurities to achieve maximum evaporation. When the filter becomes clogged, these impurities will pass through the filter, and evaporation will be slow or even stop altogether.
    • If that's not enough to motivate you, consider why evaporative cooler also has such a euphemistic name as "swamp cooler". The first machines had problems with the growth of algae, as a result of which, due to their smell, even alligators felt at home.

Tips

  • Care, care and more care. Although evaporative coolers have become easier to use, they still require some maintenance. Make sure that it is clean and that everything is working correctly, especially check it for serviceability before the predicted heat.
  • For the same reason, high-volume machines are more convenient as you do not need to change the water frequently.
  • Some evaporative cooler models have pumps to remove impurities from the filtration system. You can use this water on plants or grass that do not mind soaking up water with a high salt content (salt is the main impurity in water). If you don't have anything that this water can go for, try diluting it with even more water.
  • High volume evaporative coolers are not always the best. Look for chillers that are highly efficient and use little water. In addition, it will be difficult for you to carry large volumes of water from the source to the chiller.
  • Some people advise using a combination of evaporative cooler and air conditioner. It is silly if you are trying to save on energy and help the environment. Instead, on hot days, turn on your evaporative cooler to cool your home at night. Turn off the chiller during the day, close windows and blinds to keep out cold air, and turn on a regular air conditioner if you need to maintain a comfortable temperature.

Warnings

  • Do not run the evaporative cooler and air conditioner at the same time. They use different work processes and, in essence, do exactly the opposite work. You may feel cool, but this puts a lot of stress on the air conditioner, which will cause your electricity bills to be much higher than they should be.
