So, it’s time to get to know the evaporative cooling system, how it works and what are its benefits. Are you ready to beat the heat forever?
What is evaporative cooling, How Does it Work and Benefits?
1. Evaporative cooling- history
For ages and centuries, people are known for trying to fight the heat during the summer. Believe it or not, even ancient Greeks and Romans had the methods of cooling down their houses by placing wet mats on the windows and doors. However, the technology has advanced since that period and we can enjoy a nice cool air inside our homes without covering it in a wet cloth.
The first mechanical ventilation system was invented in the 15th century. But the evaporative cooling system we use today was designed in Britain in the 18th century. Thanks to Brits, we can now enjoy sitting in our homes during heat waves. But have you ever wondered how does the evaporative system work?
2. How does evaporative cooling work?
Just like the name says, evaporative cooling works by evaporating water. It’s a device you install in your home or premises that keeps your space cool during hot summers.
The secret lies within the components of this device. In the middle of it is a cooling pad that allows evaporated water to pass through and cool down your premises. But how can evaporation cause cooling?
An evaporative cooling system relies on water distribution. This is the main reason this device keeps your home cool. The water from an evaporative cooler evenly spreads across the cooling pad, which maximises the wetness.
This means that the wetter the cooling pad, the better the cooling is. Fans in the cooling system draw water from the pad, which causes evaporation. This cools your home down.
3. Evaporative cooling and viruses
One of the main worries many people have regarding different cooling systems is the viruses and bacteria that may go through with the ventilation.
This became especially important in 2020 when the coronavirus outbreak affected the entire world. Imagine not being able to turn on your cooling system because it helps the spread of the virus. Is that the case with evaporative coolers?
Since they use water to work, many people think that humidity is an ideal atmosphere for spreading bacteria and viruses. However, this is not the case with most evaporative coolers.
They deliver high-quality clean air that is pre-filtered before it enters your home. It’s safe to say that most bacteria and viruses remain on the filter, which prevents their spreading.
4. Water usage
Since you know now that the evaporative cooling system uses water to function, it might be logical to ask how much water does it use. Would it be worth it if the evaporative coolers used a lot of water?
Not only would that be costly, but also very bad for the environment. Believe it or not, the average usage of water is 15 litres a day.
Compared to the one washing machine cycle, that spends from 60 to 150 litres of water per one wash, we can agree that evaporative coolers don’t spend much water.
If you compare it to the water you spend showering, it’s known that an evaporative cooler spends 98% water less than a shower in a year!
Have you noticed that very hot summer days feel dry? It’s almost like you can’t breathe in the hot air, which can be quite tiring and scary. That’s why evaporative cooling systems can help you get through the hot days by humidifying the air. The hotter the day, the drier the air which leads to more cooling done by your evaporation cooler.
By choosing an adequate evaporative cooler, you can ensure to have a high-quality humid air inside your home. Most evaporative coolers work extremely well even in humid environments.
Unlike a simple fan that just blows the hot air around, evaporative coolers will increase the humidity in your area. The level of humidity depends on the temperature and adjustments you’ve set, but it can be increased by 2 to 5%.
6. Why is it good for you?
One of the most vital benefits of using an evaporative cooling system is non-stop fresh air in your home. A constant flow of fresh air through your premises ensures that indoor pollutants, such as CO2 won’t build up in your area. Unlike the air conditioners, evaporative coolers don’t use chemicals and don’t endanger your health when being used.
Just like we’ve mentioned, evaporative systems humidify the air in your home, which improves the cooling process. Besides that, slightly humid air is much better for your health.
On the other hand, you’ve surely noticed how air conditioners dry out the air you breathe in, which can cause a lot of health issues, like respiratory problems and sore throat.
6. Evaporative cooling and environment
Another major benefit of this type of cooling system is that it’s great for the environment. If you’re trying to build a sustainable home, based on the eco-friendly lifestyle, using an evaporative cooler is a much better option for the environment. Unlike the other cooling systems, evaporative cooler uses less power and electricity to run. How?
Like we’ve previously explained, this system uses the natural process of evaporation to cool down your premises and moisturise the air you breathe in. It keeps the air fresh and it doesn’t need to be recycled. Evaporative coolers don’t contain harmful refrigerants, which is beneficial for you and for the environment.

7. Quiet operations
Is there anything more annoying than a sound of the AC humming during the night? You can’t open your windows as it’s still hot outside, but you can’t turn off your AC either as you won’t be able to sleep in such a hot environment. The AC is usually located near your home or even a window. To work properly it uses the compressors that make that irritating sound.
Unlike the ACs, evaporative coolers don’t use compressors. They use a simple fan and a motor. That’s why evaporative coolers are quiet when operating.
Since the technology advanced so much, evaporative coolers with whisper-quiet operation exist, which are ideal for households with small children or light sleepers.
8. Low cost cooling
Unlike the refrigerated system, such as an AC, installation of the evaporative cooler is much less costly.

Besides using less power to function than the regular air conditioner, it is also much cheaper to run. It is estimated that running a refrigerated system annually costs twice as much as running an evaporative cooler. Why is this the case?
Unlike the evaporative cooler that runs on the water and fans, refrigerated systems use much more electricity and power to run pumps and compressors. That’s the main reason why they spend a lot more energy and result in higher electricity bills than evaporative cooling systems.
9. How is it installed?
Just like any complicated gadget and device in your home, the evaporative cooler also requires proper installation. Even though you think you may be able to implement it by yourself, it can be quite tricky and dangerous.
That’s why you need to contact professionals who will be able to install an evaporative cooling system in your home. A qualified person needs to install the rooftop unit, implement the water, power and set the controls adequate for your home.
Besides installing, you’ll need frequent servicing. To properly service the evaporative cooling system, you also need to contact the reliable professionals who will quickly and effectively service and repair any problems regarding your cooling system.
The reliable experts will also make sure to set your evaporative cooler for peak performance during the hot summer days.
10. Maintenance tips
Even though it may not seem like it, evaporative cooling systems are quite easy to maintain. Filters, water tanks and fans should be cleaned every six months or so.
However, if you use it only during three months, it is advisable to clean evaporative cooler before you start and after you stop using it.
Unlike the other components, cooling pads need to be cleaned more often. The cleaner the water in the water tank, the better the air in your house. This minimises the spread of viruses and bacteria.
So, if you use your evaporative cooler every day, make sure to clean the cooling pad frequently for top air quality and cooling.
Compared to the other cooling systems, evaporative coolers are much more efficient and healthier choice. They keep the air in your home fresh and moisturised, which prevents numerous health issues. On top of that, it’s cheaper to use an evaporative cooler than any other system. So, don’t waste your time and money on other means of cooling down your home, and opt for the best cooler on the market.
