Air Cooler: How To Upgrade and Enhance Energy Efficiency?

Air cooler, also known as evaporative coolers, are increasingly popular alternatives to traditional air conditioning systems due to their energy efficiency and environmental benefits. They work by using the natural process of water evaporation to cool and humidify the air, making them ideal for dry and hot climates.

What Are the Basics of Air Cooler?

At its core, an air cooler operates on the principle of evaporative cooling. It draws warm air from the environment through water-soaked pads or filters. As the air passes through these pads, the water evaporates, absorbing heat and cooling the air, which is then circulated back into the room. This process is effective in increasing humidity levels, which can be beneficial in dry climates.
