Evaporative Cooling vs Air Conditioning in Melbourne – Which is the Better Choice in 2024?

The Cost of Evaporative vs Refrigerated Cooling Systems

When choosing between a traditional air conditioner vs evaporative cooling, installation and running costs are key considerations. Let’s break down the cost aspects of both systems:

Installing an evaporative air conditioner tends to cost less, as the system is simpler with fewer components. Ducted refrigerated air conditioning requires more complex equipment, such as compressors and ducting, leading to higher installation costs. 

Evaporative coolers are more energy-efficient as they use much less power. They only need the energy to pump water and power a fan. In contrast, air conditioners are known to require more electricity to run and can hike up energy bills. On very hot days, energy consumption in air conditioners tends to increase.  

Both systems require regular maintenance. Evaporative cooling units need consistent cleaning of the cooling pads and regular water pump checks. Air conditioners require filter cleaning to ensure air quality and performance. Ducted air conditioning systems may have higher maintenance costs due to their complexity.

Air Quality: How Do Evaporative and Refrigerated Systems Differ?

Air quality is an important factor when choosing a cooling system. Let’s compare the benefits of each for your home’s air circulation:

A ducted evaporative cooling unit constantly draws in fresh air from outside and distributes it throughout your home. This improves the air quality since it doesn’t recirculate air that’s already inside. You get revitalised, cleaner air. However, added moisture can be a negative during humid days, potentially leading to mould or bacteria if the system isn’t properly maintained.

Select Bonaire cooling solutions have humidity management systems built in which adjust water levels to help combat over-humidification.

Air conditioners, on the other hand, use refrigerated cooling and recirculate air. Modern air conditioning units come equipped with filters that remove dust and particles, improving indoor air quality. Reverse cycle air conditioners can dehumidify the air, preventing moisture buildup in humid conditions. However, for optimal health, these filters need regular cleaning.

In 2024, newer models of both ducted and split system air conditioning offer air purification built in. This reduces the spread of airborne viruses and bacteria, improving the air quality in your home. Take a look at the Panasonic ducted air conditioner for more information. 

If you find the air too dry and need to run a humidifier with traditional air conditioners, you might prefer how evaporative coolers work. As they add moisture to the air throughout your home.

Environmental Impact of Evaporative Cooling vs Air Conditioning

Evaporative units use significantly less energy than most air conditioning units due to their simple design. They are highly energy-efficient, making them ideal for eco-conscious households.
 
Refrigerated air conditioners use more electricity, particularly on hot days. While modern air conditioning systems are designed to be more efficient, they still consume more power compared to evaporative systems.

Higher electricity use by air conditioners contributes to more indirect greenhouse gas emissions. Additionally, some refrigerants used in older air conditioning systems can harm the environment. Meanwhile, evaporative cooling has a smaller environmental footprint, using less energy and relying on natural cooling through evaporation.

One downside to evaporative cooling systems is their reliance on water. While these systems use less power, they do require consistent water availability for the evaporation process. This could be problematic during periods of water restrictions.
