Have you ever gone for a run and started sweating profusely? Then when you sit on the park’s bench to relax, you can feel the sweats making you feel cool when the soft breeze hits you. This is exactly the right mechanism followed in evaporative cooling. This is one process when the liquid water evaporates from the surface region, decreasing its temperature while doing so. Whenever sweat evaporates from your skin, it leaves a chilly feeling behind. You need to go through this article completely to learn more about this cooling process.

Understanding the Cooling For understanding evaporative cooling, it is better to learn more about heat and evaporation. Water holds maximum heat without changing the temperature. The heat stored here is known as latent heat. Water gets to absorb heat from any other surface region, making them a lot cooler.

  • When water absorbs enough heat, the liquid will evaporate or change its state from liquid to gas
  • This gas will further leave the surface and taking that extra heat with it
  • This results in decreased heat amount also decrease the surface temperature

This is how this process of evaporation cooling works. This mechanism is currently used in various HVAC unit projects, and the results have been outstanding. Learning about the products beforehand can serve the purpose well.

Evaporation Cooling Based AC Systems:

Nowadays, you will come across evaporative cooling based AC units, which will use the cooling effect of liquid evaporation to cool an airstream directly or indirectly.

  • You can get it in a factory assembled unit or in the field built system; whichever matches your choice the most
  • Even though the evaporative cooler offers you a portion of this current cooling effect, it becomes a component of centralised hydronic or that packaged unit system
  • The selective evaporative cooling system comprises filters, intake chamber, direct contact or indirect contact exchanger for heat, supply fan, water sprays, exhaust fan, water sump and recirculating water pump.
  • You can easily characterise these mechanisms by lower energy use when compared to refrigeration cooling. They are ready to produce that humid and cool air, which can be used widely.

Vital Points about Modernized Evaporative Coolers:

The modern day’s evaporative coolers are quite sophisticated when compared to their old counterparts. It is quite effective in the lower humidity areas and will offer that energy-efficient and natural cooling method.

  • In the modern cooler dealing with evaporative cooling, a pump is the main body, used for circulating water from an inbuilt reservoir to a porous cooling pad. This pad holds the water well.
  • Then you have the proper use of an electric fan, which will draw air into a unit that will furthermore flow through the moistened pad.
  • When the warm air passes through the pad, it will transfer heat to water. Then the water will evaporate as vapour, which reduces the air temperature.
  • One major element to maintain an efficient evaporative cooking process is to ensure that the pads remain in a completely saturated form.
  • You need to be sure that the electric motor and fan are in their suitable sizes so there remains a proper airflow through the pad. The output related to cool air must match with the environment’s needs where the cooler is likely to be used.

Once you are well-aware of the evaporative cooling method, purchasing a cooler for the same will work out well. Things will work out in your favour once you got the unit from reputed manufacturing units.
