There is absolutely nothing to scratch your brains on this topic as it's the basic chemistry that plays in this phenomenon. It is a concept that we may also notice while doing things as simple as drinking coffee from our favourite mug or having food. Before talking about this process of evaporative cooling, let us first discuss what evaporation is.

Overview of Evaporative Cooling- Points To Note

Evaporative cooling is a method of cooling hot air with the help of evaporated water. Here, we can take an example of a swimming pool to understand this concept slightly better. When we come out of a swimming pool and the sun is too bright to tolerate, we still feel a cooling sensation because of the water that is being evaporated from our bodies. 

Another example we can imagine is a hot sunny day when we return home from the grocery store or school with a whole lot of sweat on our bodies. Even if we don't have the fan or air-conditioner on, after a few minutes, we start to feel cold because the sweat, which is in the form of liquid, evaporates and dissipates heat from our body and leaves us with a cooling sensation. That is the basic concept of evaporative cooling.

The Science Behind Keeping Cool: How Evaporative Cooling Works

Now, someone may ask, what is the practical application of evaporative cooling? How is this useful? So, in this section of the article, we will discuss how an evaporative cooler can be used in our daily lifestyle and how this works efficiently to save us some money.

When the outside air is drawn inside by an evaporative cooler, it immediately comes in contact with the wet pads attached to it and evaporates the water. Along with it, the heat also disappears, giving cool air in return.

Evaporative cooling can act like a wonder if you want to save some money, and this can be applied anywhere, be it your home or office. Let's say you want to bring down the cost of using an air-conditioner at your home, so you can use an evaporative cooler and get the desired result of a cool atmosphere.

Don't Let The Heat Wave Get You Down - The Difference Between An Evaporative Cooler And An Air-conditioner

An evaporative cooler works by continuously transferring the fresh air from outside to inside a room. At the same time, an air-conditioner works by circulating the same air, which is inside a room, again and again.

No coolant or compressor is required in the evaporative cooling method. On the other hand, both are needed for an air-conditioner to work. That is the reason why air-conditioners are on the expensive side as compared to evaporative coolers. 

Air-conditioners also use more energy when compared to evaporative coolers, which use very less energy. Part of the reason could be that evaporative cooling works without any compressor or coolant, which is why they are a better option to consider over air-conditioners.

Different Types Of Evaporative Cooling To Keep You Comfortable All Summer Long

Below highlighted are the different types of evaporative cooling system you need to know about:

1. Direct: It is the method that makes use of an authentic evaporative cooler that was explained above in this article. By drawing the outside air inside, wet pads enable the evaporation of water and eliminate heat, making the room chilled. It is the most preferred method of evaporative cooling everywhere.

2. Indirect: In this method, heat is transferred ahead via a heat exchanger, which has consecutive dry and wet streams of air. Water is dripped over those wet airstreams, and consecutively a fan is switched on, resulting in the evaporation of water.

It leaves the heat exchanger cooled, and the air is allowed to pass from the dry airstreams of the heat exchanger. Air coming in contact with the chilled heat exchanger passes onto the other side imparting cool air.

Conclusion

So, these were some helpful points you needed to know about how evaporative cooling works like wonders. It also gave a general explanation of the types of evaporative coolers and how they are better than an air-conditioner.
