Not only it has a similar cooling effect as an AC, but it is also portable. Other than this, most of the evaporative coolers are energy efficient and come with functionalities like air purifier and humidifier. There are countless other aspects to discuss with the evaporative coolers. Let’s take a look at them in the sections below!
What is an Evaporative Cooler?
Evaporative coolers are often termed swamp coolers. They use moisture for cooling the air inside your house combining the cooling properties of the vaporising water with a powerful airflow system.
All the coolers consist of a fan, an internal motor and a water tank. The motor passes the dry air through the internal filter pad that is wet. Then the air is quickly cooled and is circulated throughout the room. Opening nearby windows will help you in renewing the air every few minutes and keep it fresh.
These water-filled pads usually act as the filter in removing dust and allergens from the indoor air. They also use very little energy, making them an environmentally friendly option. However, both the cooler and the pads need to be properly maintained and cleaned to avoid releasing a swamp-like or marshy odour. You should consider the replacement of the cooling pad at least two times in a season to avoid such issues.
At this point, you might be wondering: “Do evaporative coolers work effectively though?”. You are not alone, many people have the same question in their mind. The answer to this question is yes. The evaporative coolers need dry and hot air for effective function, so they are best for locations with warm and dry climates.
How do Evaporative Air Coolers Work?
The evaporative coolers are meant to cool the air via the process of evaporating the water. When the water evaporates into the air, the result is a mixture of air and water molecules. That’s why these coolers create the effect of a light breeze, almost like nature.
Their oscillating fans pull in the dry and stale air, then pass it through the water-moistened cooling pad or rigid cooling media. From that point, the cool water evaporates into the air. It is said that evaporative coolers should not be used in closed spaces, but in rooms with open windows or doors. Fresh air is drawn into the cooler, circulates in the room and then just exits the door.
This will ultimately help create a gentle and cool breeze for reducing the air temperature in your house. Coolers are an affordable cooling solution for users. That's because their operating cost can be 75% lower than that of any air conditioner.
