Evaporative Cooling vs. Refrigerated Cooling - Which one should you choose?

We bet you don’t want to spend your Melbourne summers all hot, tired, and cranky.  When it’s hot outside, having a cooling system brings sweet relief. That being said, two of the most popular cooling systems are evaporative cooling and refrigerated cooling. But which one should you choose?

Evaporative Cooling - Refrigerated Cooling

Melbournians trust Evaporative Cooling and Refrigerated Cooling systems to beat the summer heat. But it can be a daunting task to evaluate the pros and cons. Therefore, ComfyHome has created this informative piece to help you decide which cooling solution is right for you and your home. So, without further ado, let’s get started.

First Up, How Does Evaporative Cooling Work?

Evaporative cooling is a system that cools your home by taking the warm air from outside and passing it through moistened pads. As the warm air passes through, it evaporates. The cooled air is then distributed throughout the house. There is no use of refrigerant gases in this cooling system. It works best when the climate is dry.

How Does Refrigerated Cooling Work?

What is ducted air conditioning A refrigerated cooling system works by removing hot air inside a home, uses refrigerant gases to cool the air, and blows back the cooler air into the home. There are two components of this system: an indoor fan coil unit and an outdoor condenser unit. Given that the air re-circulates in this system, insulation of your home is imperative. A refrigerated cooling system works best in all climates, and the outside temperature doesn’t have a huge impact on the cooling.

Difference Between Evaporative Cooling and Refrigerated Cooling

The following is an in-depth review of the differences between an evap system and a refrigerated cooling system that can help clear things better:

Upfront Costs

Buying an evaporative cooling system is significantly cheaper than a refrigerated system. An ideal evaporative cooling system should replace the indoor air once every 2 minutes. Depending on the size you choose, the total unit cost can vary.

The installation cost of both units depends on factors such as the home area that requires cooling and whether it is a brand new installation with ducting or a changeover. For instance, the installation costs of a fully supplied and installed standard 12.5kW Ducted Reverse-Cycle Air Conditioner could cost you about $7000 – $9000 in Melbourne. It would be best to consult with a professional for an accurate quote.

Running Costs and Operation

An evaporative cooling system is considered one of the cheapest whole-house cooling solutions available. A standard size unit of 10-15kW capacity can have a running cost of 20¢ / hour. With an evaporative cooling unit, you could save up to 80% on energy costs.

On the other hand, a refrigerated air conditioning unit can be very energy-efficient with zoning. Buying a unit with a 6 or 7-star energy rating could further lower the energy consumption. Read this informative piece to estimate how much it costs to run an evaporative cooler and ducted refrigerated unit running cost.

Performance & Flexibility

Evaporative cooling systems work best when the climate is warm and dry, just like Melbourne’s summer months. However, when there is high humidity or temperature gets to extreme levels, this system does not cool as effectively as a refrigerated air conditioner.

An evap cooling unit can cool down your home up to 7-10 °C, but it will start to struggle if the temperature goes above 38 Co. On the other hand, a refrigerated air con provides better cooling and temperature control in all weather conditions. Moreover, ducted reverse-cycle can also warm up your home during winter.

Air Quality and Environmental Impact

Evaporative cooling units supply 100% clean, fresh air to your home by filtering the air of airborne allergens and dehumidifying it. Evap cooling is also considered the healthiest choice, especially for those who suffer from respiratory allergies and difficulties. In addition, it certainly lowers your carbon footprint because it uses water as a natural coolant and consumes less electricity.

In contrast, refrigerated air conditioners recirculate the indoor air, which often makes the indoor air stale. It also removes moisture from the air, causing dryness of skin, throat, and eyes. Moreover, it uses more electricity than an evap cooling unit, which inevitably increases your energy bills and carbon footprint.

The Maintenance Factor

Although evaporative cooling has many benefits, it is important to remember that the unit requires routine cleaning to work at its full potential. It is because lack of maintenance could lead to the accumulation of debris and mineral deposits. Moreover, there is always a chance of bacterial and mould growth inside the unit. Evaporative cooling service is the only way to prevent it from happening.

The same can be said about ducted refrigerated air conditioners as well. Although there is no accumulation of mineral deposits and salt in the system, ducted air conditioning service is important for consistent optimal performance.

Evaporative Cooling vs. Refrigerated Cooling: Which One Is Better?

If you are more eco and allergen-conscious, there is no better option than an evaporative cooling system. It is a beneficial cooling solution as long as you regularly clean it.

If you are looking for a versatile system that offers year-round comfort, opt for a refrigerated cooling unit. Despite the extra costs, it provides complete climate control.

That being said, it is important to understand that both cooling systems are capable of getting you through Melbourne summers.
