Traditional air conditioning units can be difficult to install and expensive to run. But if you live in a dry, hot climate or are trying to cool a room that has very low humidity, then a window cooler may be what you’re looking for.
The choice of an evaporative cooler depends on the size of the room that you want to cool. A window installed cooler is normally effective in a room that is 750 square feet or less, and can reduce the temperature of that room by up to 15 degrees Fahrenheit. So they may be the perfect option for a garage, office or medium sized room in your home. They are relatively simple to install and the units are usually fully assembled out of the box. An advantage of these type of coolers is that they run on 120V of electricity so that you can move it from one room to another without worrying about whether or not you have the correct power outlet – something that you would have to worry about with some window air conditioners.
The design of a window cooler is normally as slim and space-saving as comparable window air conditioners. Look for one that has more than one air speed as well as individually adjustable louvers in both the horizontal and vertical directions so that you can precisely control the air flow. You should compare the CFM (cubic feet per minute), the measurement of the area that the cooler will effectively cool. Consider the water capacity of the unit as well because you will have to replenish the water supply from time to time as the hot air continues to be cooled by the evaporation of the water in the unit.
Because evaporative coolers pass hot, dry air through a wet pad, they have one benefit over traditional air conditioners. They act as a form of air purifier and ionizer as well as an air cooler. As the fresh air passes through the damp pad, dust and other particles are captured in the pad instead of passing into your environment. In fact, if you use purified water in the window cooler, you can further enhance the purification of your air supply.
