When the summer comes, we are all grateful to have the air conditioner at home. But when we got the bill, it was a bit hurt to see the numbers on it. Air conditioners are great products but consume much electricity when we are using them. Thus we have another product named Evaporative Cooler which is not using the compressor. But how did the unit cool down the air with only a fan and water?
Have you ever feel cooler when you stand by the ocean or a river? The reason is simple and normal because as hot air blows across the water, it causes some of the water to evaporate and take away the heat. The air is cooled when the evaporation process.
The evaporative air conditioners use this theory to work. When hot air enters the unit which is installed on your roof, that is where the outdoor hot air is filtered and cooled as it passes through specially designed moistened pads. A fan then blows this comfortable cooled air into every corner of your home. Hot air in the house is forced to be pushed out through the open windows and doors providing your entire home with a complete change of air at least every two minutes. So in other words, you can enjoy the fresh outdoor air all the time instead of recycled indoor air.
