The Air Quality Benefits Of Evaporative Cooling

Evaporative cooling plays an important role in indoor air quality.

How Does Evaporative Cool Work?

We need to understand heat and evaporation to understand evaporative cool. Water can store a lot of heat, without changing its temperature. Latent heat refers to heat stored in water. Water absorbs heat from surfaces and makes them cool.  The gas takes the heat from the surface and leaves. The surface temperature drops and the heat is decreased. This is how the evaporative cooling process works. It’s like boiling noodles on the stove. The stove transfers heat from the stove to the water in a pot. The water absorbs heat and then releases steam.

Evaporative Cooling: Importance

Evaporative cooling can be used in biological and mechanical processes. Our bodies are built to sweat to release heat and maintain a comfortable temperature. Water is released from the skin through sweat. The water in sweat absorbs heat from the skin and eventually evaporates. This lowers our body temperature and prevents us from overheating during the summer.

To lower the temperature within a building, air conditioners use evaporative cool. Evaporative coolers use warm air to heat the room and filter it through a evaporative cooler pads that has been soaked in water. The pad can absorb heat from the air, and evaporate it. As water absorbs heat from the air, the temperature of the room drops and is returned.

Advantages Of Evaporative Cooling

Advantages of evaporative cooling are:


Comfort is a function of temperature, relative humidity, airflow, clothing, and work rate. The most obvious benefit of evaporative cooling is the increase in comfort caused by the lower temperature of the air used to cool buildings. One common concern is the increase in relative humidity.The impact of a temperature drop on comfort is much greater than the effect of a relative humidity rise.

Static Power

Low relative humidity, usually below 40%, can cause static electricity to increase. This can lead to discomfort for people and/or problems with processes. Static electricity can cause large sheets of paper to not fit into printing presses or finish equipment at the required speed. To reduce static problems and improve productivity, evaporative cooling can both lower the temperature as well as increase the relative humidity.

Air Cleanliness

The filter pads trap larger polluting particles like pollen grains as the air passes over them. The evaporative cooler works as part of a ventilation and air conditioning system. The fresh air that is constantly brought into the building is processed by the system. It is much healthier than systems that recycle air.

The Environment

The environment is the last aspect of air quality that should be considered. Conventional refrigeration-based air conditioning systems can negatively impact the environment through the increased energy consumption and use of potentially dangerous refrigerant gasses. Evaporative coolers typically use 10% less electricity than comparable refrigeration-based coolers. It is almost indestructible to the environment because it uses only pure water.


A simple device, the evaporative cooler, can provide benefits for indoor air quality. You will feel more comfortable and cleaner thanks to the lower temperature and the freshening of the air. Evaporative cooling is extremely eco-friendly because it uses very little energy and does not use refrigerants. Evaporative cooling plays a vital role in modern building air quality.
