Is Evaporative Cooling Eco-Friendly and Affordable?

Evaporative air conditioners are one of the most environmentally friendly cooling solutions. This is due to the fact that they utilise significantly less electricity when compared to refrigerated systems, resulting in a reduction in the consumption of fossil fuels such as coal and natural gas. Because of this, investing in a high-quality evaporative cooling system will not only result in cheaper operating expenses, but it will also reduce the household’s carbon footprint.

Many homeowners in Melbourne rely on evaporative cooling systems for cost-effective and eco-friendly cooling. It is because the evap unit is a smarter, safer, and more energy-efficient alternative to typical air conditioning systems. Evaporative coolers use up to 75% less electricity than conventional air conditioners, contain no harsh or harmful chemicals, and only require a limited amount of water to provide adequate comfort.

Before we find out more about how an evaporative cooler is an eco-friendly cooling solution, let’s take a look at how the system works.

How Does An Evaporative Cooler Work?

How does evaporative cooling workEvaporative coolers work by drawing hot air from the outside and passing it through a succession of wet filter pads that are fed with water from a tank at the base of the machine before cooling it down. Heat is removed from the air by evaporating water from the filter pads, which also humidifies the air. The system then circulates moist, cooled air throughout the house.

Part of how evaporative coolers function is by circulating cold indoor air, and part of how they work is by creating a cool breeze. That’s why it is best to keep some windows open for cross ventilation and proper cooling for the house.

We have a detailed article on what is an evaporative cooler and how does it work, so give it a read.

How Evaporative Cooler Reduces Carbon Footprint?

According to the findings of a two-year study conducted by Eurovent, the European Association for Indoor Climate, Process Cooling and Food Cold Chain Technologies, refrigeration systems that use wet, evaporative cooling towers have a lower annual carbon footprint than alternative cooling systems.

As per the study, titled “Evaporative Cooling 2030′′, the evaporative cooling industry might contribute to the reduction of up to 56,000 tonnes of CO2 per year in the future.

How Is Evaporative Cooling Eco-Friendly?

The fan, electronic control, and a small water pump are the only components of an evaporative cooler that require electrical power to operate. The outcome is reduced operating costs for evaporative cooling, which uses up to 80 percent less energy than refrigerated air conditioning, resulting in less consumption of fossil fuels such as coal and natural gas in the production of electricity.

Take an example of a Breezair evaporative cooler that produces around 20 percent of the carbon emissions released by a normal refrigerated air conditioning system. Due to the fact that evaporative coolers are based on natural technology, they are one of the most environmentally friendly methods of cooling currently available. Moreover, evaporative cooling systems do not use any toxic synthetic refrigerants to cool the environment.

Benefits of Evaporative Cooling

It is better for the environment to use evap units in Melbourne, which imitate the earth’s natural cooling process.  When compared to air conditioners, evaporative cooling utilises about 80–90% less electricity.


A significant advantage of evaporative cooling over refrigerated cooling is that it does not introduce chemicals into the air, ensuring that there is no pollution.

The Lowest Operating Expenses

These units use just electricity to naturally cool the air in the room, making them an excellent choice for those looking to save money on utility bills.

Low Level of CO2 Emissions

When it comes to refrigeration units, carbon dioxide can be an issue; however, evaporative cooling machines emit very little carbon dioxide into the atmosphere.

Fresh, Clean Air 

Evaporative coolers keep the air in the room fresh; because windows and doors can be opened, the air circulates and becomes healthier, reducing the likelihood of airborne illnesses.

Increases The Amount of Moisture In The Air

When it comes to refrigeration systems, dry air is frequently a concern. Evap units introduce moisture, which makes breathing easier.

Difference Between Evaporative Cooling And Air Conditioning

Evaporative Cooling VS. Ducted Refrigerated AC - Which to choose?

Evaporative coolers and refrigerant air conditioners use two distinct methods for cooling. While evaporative coolers utilise water to help cool the home, a refrigerant split system employs a refrigerant gas to cool the home, as well as two compartments that exchange the hot air within the room with cooler air from the outside, to help chill the home. Despite the fact that the operating expenses of a refrigerant air conditioner are significantly higher, evaporative cooling is not ideal for people who live in high humidity areas.

Traditional air conditioning unit technology draws in air from within a home or area, processes it via the cooling system, and then recirculates that cooled air back into the home. Although this procedure is effective, the indoor air may become staler as a result of it. To ensure that your air conditioning equipment operates at peak efficiency, you need to ensure that all windows and doors are closed.
