What is evaporative cooling and how does it work

How does an evaporative cooler work?

Evaporative cooling, also known as adiabatic cooling, works on the principle of water evaporation, through which air is cooled to a comfortable temperature. It is a cooling and ventilation method that uses water as its refrigerant.

The function of an evaporative cooler

The function of evaporative cooling is that water is evaporated in the air stream and transferred from liquid to gas during the evaporative cooling process. This transfer requires energy extracted from the air in the form of heat. As a result of this process, the air is cooled.

Types of evaporative coolers

This evaporative cooling process can be applied in several ways:

  1. Direct evaporative air coolers.
  2. Indirect evaporative air coolers.
  3. Mounted air cooler.

Evaporative cooling parts

  • Engines
  • Engine pulleys
  • Belt
  • Blower reels
  • Bearings and shafts
  • Tee kit and off blade
  • Drain and overflow pipes
  • Pump basket and filter plate
  • Air cooler and air freshener
  • Floating valves
  • Pads
  • Pumps
  • Water distribution
  • water supply

Evaporative cooling system

In an evaporative cooling system, warm outside air is forced through wet cooling pads by a motorized fan.The cooling pads are continuously moistened by a water pump that delivers water to the cooling pads. Then, the cooled air is blown into the environment. Then, the exhaust air can be evaporatively cooled between 60% and 90%, depending on the environment’s efficiency.

Evaporative cooler advantages

Using an indirect/direct system, evaporative cooling is a highly efficient method that provides a comfortable and productive environment for manufacturing facilities, distribution centers, and office buildings. This cooling method is efficient compared to traditional air conditioning systems that use refrigerants and compressors to achieve cooling.Additionally, unlike mechanical cooling, evaporative cooling does not recirculate hot, polluted indoor air but ventilates fresh, filtered, clean, and cool air into the environment. As a result, indoor air quality improves significantly.

Evaporative cooler disadvantages

Evaporative coolers should not be used in humid climates because they add moisture to your ambient air. Also, they do not cool your environment less than an air conditioner, and they require simple maintenance about once a month.

Also, evaporation systems for people who are very sensitive and humidity aggravates their sensitivity. They are not suitable. Evaporative systems may rust after a few years due to contact with water. (if not insulated).

Evaporative cooler reviews

There are different reviews about evaporative cooling, and we will express some of them:

  • In most of the comments, they wrote that the maintenance of these evaporative coolers is very easy, and they are easily moved.
  • And they also wrote about the ease of setting up and the quietness of this evaporative cooler.
