A 2024 review published in Buildings by Misrak Girma Haile and colleagues highlighted that evaporative cooling systems are highly effective in hot and dry climates. The review shows that these systems can achieve high cooling efficiency, low energy consumption, and favourable performance when compared to traditional air conditioning.

In this blog, we’ll explain how evaporative air conditioning works and why it’s a smart choice for your cooling needs.

How Does Evaporative Cooling Work?

Unlike traditional air conditioning, which relies on chemical refrigerants and recycled air, evaporative air conditioners use fresh outdoor air and water to create a refreshing indoor atmosphere. 

As the name suggests, the system works by passing warm air through water-saturated pads, causing the water to evaporate and cool the air before it’s circulated throughout the building.

Here’s how the system works in detail:

  • The system starts by drawing in fresh air from outside.
  • As the air passes through water-saturated cooling pads, it is cooled and naturally filtered, removing dust and some airborne particles before entering your space. This ensures that the air is clean and free from contaminants.
  • The cooled air is then pushed through ducts that distribute it evenly throughout your space. 

What Are the Advantages of Choosing an Evaporative System?

1. Energy Efficiency and Lower Running Costs

Evaporative coolers use significantly less energy than traditional air conditioners, saving you up to 75% on electricity bills.

2. Eco-Friendly

As mentioned previously, these systems use water evaporation to cool the air, meaning no chemicals or refrigerants are involved. This makes evaporative air conditioners a greener choice, helping to reduce your carbon footprint.

3. Fresh and Healthy Air Quality

Unlike traditional systems, evaporative coolers bring in fresh outdoor air, continuously circulating it throughout the space. This constant influx of fresh air helps prevent stale, dry air from building up, improving indoor air quality. The continuous flow of clean air makes evaporative cooling an excellent choice for individuals with allergies or respiratory issues.

4. Quiet Operation

Evaporative coolers are much quieter than traditional air conditioners, making them ideal for bedrooms or any space where noise levels matter.

Selecting the Right Evaporative Cooling System for Your Space

1. Assess the Size of Your Space

Choose a system based on the size of the area you need to cool. For small spaces, a portable or window-mounted unit is ideal. Larger spaces will need a ducted system to cool multiple rooms efficiently.

2. Installation Requirements

Portable systems are easy to set up, while ducted systems require professional installation, which can be more time-consuming and complex.

3. Budget and Long-Term Savings

While ducted systems have a higher upfront cost, they offer long-term savings on energy bills. Portable systems are more affordable but only suitable for smaller spaces.

4. Additional Features

Consider systems with digital controls and timer settings, which offer greater convenience and help you manage your cooling more effectively.

How to Maintain an Evaporative Cooling System

To keep your evaporative air conditioning system running at its best, regular maintenance is important. 

1. Change Filters Regularly

Over time, your filters can get clogged with dust and debris, which can reduce your system’s efficiency. While you can clean or replace the filters yourself, it’s a good idea to have our team of professionals handle this at least once a year. We’ll make sure everything’s cleaned or replaced properly.

2. Check Water Quality

It’s essential to keep the water in your unit clean to prevent mineral build-up. Check the water every few months. If you spot any signs of scale or debris, it’s time for a thorough cleaning. Our team can do this quickly and efficiently, ensuring your system stays in top condition.

3. Inspect Ductwork

Dust and debris can build up in the ducts over time, which can restrict airflow. While you can do a quick inspection yourself, it’s best to leave the deep cleaning to the experts and have it done once a year. We can clean your ducts thoroughly, ensuring optimal air circulation and helping avoid any long-term damage. 

Conclusion

Evaporative cooling systems offer a cost-effective, eco-friendly, and healthy way to keep your space cool in hot and dry climates.
