What Is Evaporative Cooling In Coolers?

April 10, 2022

Evaporative cooling, also known as adiabatic cooling in swamp coolers, works on the idea that water evaporates into the air, which cools the air down to a temperature that is safe for you.

It is a way to cool and ventilate your home that uses water as its refrigerant.

To cool down, water is evaporated in the air and changes from liquid to gas, which means it cools down. This change needs energy, which is taken from the air in the form of heat. Air is cooled down because of this.


As Water Evaporates, It Cools The Air

The hot outside air is forced through wet cooling pads by a fan that moves with the help of electricity. The cooling pads stay moist all the time thanks to a water pump that sends water to the cooling pads. Then, the cooled air is blown into the building. Between 60% and 90% of the wet bulb can then be cooled down by the evaporative media. This depends on how well it works. There is a lot of humidity in the air that comes out of the vents. It's cooled down 10 to 15 degrees, but it's still very hot. Direct evaporative cooling should not be used to cool places where people work or live.

This is not the case with two-stage evaporative cooling: it can achieve efficiency levels of up to 114 percent of the wet bulb. As a result, two-stage evaporative cooling processes can achieve lower temperatures of up to 7°C and 60% less humidity than direct evaporative cooling processes.


Evaporative Cooling Is Important Because It Helps Keep The Air Cool

Evaporative cooling, which is done through an indirect/direct system, is a very green and energy-efficient way to cool down production facilities, distribution centers, and office buildings. 10% of the energy needed for mechanical cooling is used in an indirect/direct cooling system because evaporative cooling is used to cool the air. This process also delivers the same or close to the same temperature as traditional mechanical cooling systems. In addition, unlike mechanical cooling, evaporative cooling doesn't keep the warm, polluted air inside a room or building. Instead, it ventilates 100% fresh, filtered, clean and cooled air into a room or building. As a result, the quality of the air in your home dramatically improves.


Evaporative Cooling Has A Long History

As far back as humans have been around, evaporative cooling has been used to keep people's homes cool. As far back as 2500 BC, murals have been found in Egypt that shows how water-filled clay pots were placed under an air inlet to help keep the air cool when it passed through them. They couldn't have used electric fans or other modern methods, but elements of evaporative cooling were used in the design and architecture of their homes, which helped keep the temperature at a safe level.
