The Ways of Benefitting from Evaporative Cooling

Evaporative cooling is a centuries-old concept. But what’s even more fascinating is that it remains to be the most preferred option, and modern technology now allows us to use the idea and come up with new and highly advanced products. Passing warm air into a medium containing liquid water is its underlying principle. By taking the heat energy from it and using it to evaporate water, you can reduce the temperature of the air.


By utilising two different forms of heat energy, which is the ‘sensible heat’ and ‘latent heat’ the Evaporative cooling then works. The sensible heat significantly refers to the heat energy, which can affect the system’s temperature containing it that in this case is the air. While latent heat, on the other hand, is heat energy stored in the system which doesn’t affect the system’s overall temperature.


Some of the heat energy in the air is moved to the water when the warm air in an evaporative air conditioner passes over the system’s liquid water source. It then causes it to evaporate and form water vapour. Plus, the overall air temperature of the room will drop as some of the sensible heat from the air is transformed into latent heat contained in the water vapour.


There are three basic parts that modern evaporative air conditioner and cooling systems usually do consist of. One is the fan; second is the membrane or pad that holds the liquid water and lastly, a pump that supplies the water. In drawing warm air across the pad or membrane, the fan is used. Then, the air circulated in the building. Also, to ensure that the system doesn’t dry out, the water-carrying medium is sprayed with fresh water from the pump as needed. It helps the evaporative cooling unit to work efficiently, over long periods.


Compared to other types of cooling equipment, evaporative cooling offers more advantages.


  1. It is energy efficient.


Unlike other methods of cooling, the energy that evaporative systems require is only as low as 80%. Thus, it is undeniable that it is not only environmentally friendly but practical as well.


  1. It has a dual function.


An evaporative cooler can also help in humidifying the air besides cooling it. Other forms of air conditioning can leave the air dry. It is because it causes the water vapour to condense out of it. Thus, for drier climates, evaporative conditioning is the most excellent choice.


Variety of factors is the basis in choosing a type of air conditioning. It includes your local climate, building and operating requirements of your business. So before deciding, it is undeniable how ideal for you to consult an experienced AC technician who specialises in commercial work. You can also check these guys out if you need more help.
