How Environmentally Friendly Are Evaporative Coolers?

It is now evident that more and more homeowners are more knowledgeable about the issues concerning our environment. Lots of deliberations have been ongoing globally on the ways we can all improve and care for our environment to better our lives. This being the case, the evaporative coolers have been found to offer safer and smarter ways of improving on energy efficiency. The use of water as a means of cooling used in the evaporative coolers increases efficiency. As we all know, water has the best thermodynamic and chemical properties. On issues energy, evaporative coolers use less electricity and can save up to 75% of your energy bills. Additionally, evaporative coolers are less associated with the emission of hazardous chemicals and gasses that degrade the environment. But just how environmentally friendly are evaporative coolers? Below are some key points to just pointing out how friendly the evaporative coolers are to the environment.

1. Evaporative Coolers Don’t Use HCFCs

HCFC or Hydrochlorofluorocarbons, one of the longest words in the chemical dictionary; has been rated Class II as one of the ozone-depleting substances. HCFCs are used in the following applications, the making of aerosols, fire extinguishers, foam blowing, solvents, refrigeration, and air conditioning. The history of HCFCs dates back to the 90s having being introduced as an alternative chemical for CFC.

The Montreal Protocol added HCFC to their list of controlled substances. It is shocking to learn that the production of HCFC was 34,400ODP (Ozone Depleting Potential) tons in 2006. Shocking enough, 75% of HCFC is used in air conditioning and in the refrigeration sectors. HCFC have up to 2000-times higher levels of global warming potential than that of carbon dioxide. Evaporative coolers, on the other hand, will only use water as a means to cool your living room.

2. Swamp Coolers, Global Warming and Energy Conservation

One of the most common types of greenhouse gasses that affect our atmosphere is carbon dioxide. The generation of electricity and power stations contribute immensely to the carbon dioxide emission in the atmosphere. Energy conservation from our appliance would mean less carbon monoxide in our atmosphere, which is a nongreenhouse gas.


In addition to the fact that they don’t emit harmful gasses into the atmosphere, evaporative coolers use less electricity, making them even more environmentally friendly.

3. Humidification

Unlike air conditioners, they do not remove moisture from the air. Evaporative coolers increase the humidity levels in dry air, meaning that they can be more convenient cooling alternatives in the hotter, dryer regions of the world.


4. Evaporative Coolers Provide Fresher Air

Homeowners who choose evaporative cooler installation over central air conditioning ensure themselves that they are breathing only fresh air with the provision of having sufficient ventilation. You can open your doors and windows to free up the used up air without the worries of losing air flow. You will never have to breathe in recirculated air and you can worry less about stale air.



From the pointers above, we can safely conclude that evaporative cooling is a good choice for the environmentally conscious consumer as evaporative coolers do not use chemicals of any kind. The use of water, the simplest form of technology as a natural source for cooling the air, is a sure enough, reason why the evaporative coolers would be attributed to being environmentally friendly.
