Why Evaporative Cooling ?
Why Evaporative Cooling And What Are It’s Benefits ?
When sitting by the beach, you often feel cooler because as hot air blows across the water, it causes some of the water to evaporate and absorb the heat. The air is cooled by this evaporation process and so becomes a “sea” breeze.
Evaporative air conditioning works similarly. Hot air enters the cooling unit on your roof where it is filtered and cooled as it passes through dampened pads. A fan then blows the cooled air through the air conditioning vents your home.
Hot air in the house is then forced out through open windows and doors providing your entire home with a complete change of air at least every two minutes.
Why Evaporative Cooling Works For Adelaide
Evaporative air conditioning offers a more affordable way to cool your home than a reverse cycle unit.
You can even leave your windows and doors open, as opposed to refrigerative systems (namely ducted reverse cycle and split system), whereby you need to keep them closed to trap the cold air in.
Other advantages of Evaporative Air Conditioning systems include:
- Delivers 100% fresh air
- Uses up to 80% less electricity than comparable refrigerated systems!
- Greatly reduces costs of staying cool
- Enables lower purchase and installation costs
- Guarantees fresh, natural, healthy “lifestyle” cooling
- Allergy free, asthma-safe environment*
- Replaces all of the air approximately every two minutes
- Ensures full ventilation – drives out odours and stale air
- Never dries out the eyes and skin, or even indoor plants
Evaporative cooling is a totally natural process filling your home with 100% fresh air – there couldn’t be a healthier choice. Unlike refrigerated systems that can circulate stale recycled air, evaporative air conditioning systems filter and clean the air, which is not only great for general health and well being, but it is the ideal choice for allergy and asthmatic sufferers.*
By pumping fresh, cool air into your house and pushing hot, stale air out, evaporative air conditioning systems also operate as a ventilation system. Kitchen odours or stale air can be quickly and easily expelled from the home by turning the unit on or operating it in fan only mode.

Evaporative Cooling Benefits
Evaporative cooling systems are becoming increasingly popular to home owners in Adelaide. These systems cool a home just as effectively and does it with the doors and windows open. For this reason, many home owners consider evaporative air conditioning to be more desirable, as you get a more natural breeze through the home. Read this post for some of the key evaporative air conditioning benefits.
Evaporative Cooling Benefits – The Difference
Non-Refrigerant based Evaporative Cooling
There are many things to like about evaporative cooling. At the core of evaporative air conditioning benefits is that it is totally different to conventional air conditioning such as ducted reverse cycle or the wall split systems. This is because evaporative systems do not use a refrigerant to cool the air. Instead, warm air is sucked into the compressor, passed through water cooled pads, and the resulting cold air is distributed throughout the home via ducts. This is the key difference between an evaporative and a refrigerant based air conditioning system.
Air from Evaporative Cooling is more natural – Like a cool breeze
Due to the fact that evaporative cooling uses water to cool the air, air produced by an evaporative air conditioning system is more humid, containing a higher percentage of moisture. This means that the air feels fresher, more comfortable, just like a natural breeze. And since refrigerants are not used to cool the air, it is more natural and easier to breathe.
Although an evaporative air conditioner does not cool air as effectively as wall split system or ducted reverse cycle air conditioners, it still cools sufficiently for most climates – unless you are in a really extreme climate. On a hot summer’s day in Adelaide, with an outside temperature of say 38 degree Celsius, an evaporative air conditioner can cool a room down to 18-20 degrees. Which is still very pleasant. And that is with the windows and doors open. This creates a very pleasant breeze through the home despite the hot outside temperatures.
Refrigerant based air conditioning systems will always produce much colder and crisper air, although that air would be drier. These systems can easily bring a room temperature down to 16 degrees Celsius – even on a hot summer’s day with outside temperature close to 40 degrees Celsius.
Evaporative Cooling is Extremely Efficient
Due to the fact that its is not a refrigeration system, but rather water cooled, evaporative air conditioning uses much less power than refrigeration systems. In fact, Braemar has provided in their specifications that their evaporative systems consumes as little as 1/4 of the power that a ducted reverse cycle air conditioner consumes. That means evaporative air conditioning is possibly 4 times as efficient – if not more.
In terms of water consumption, an evaporative air conditioning system uses less water than a dishwasher in a single day. So adding up the costs, an evaporative air conditioning system actually has the lowest running cost, as compared to other air conditioning systems. Evaporative cooling companies like Braemar, has also improved their energy efficiency through other design breakthroughs, putting out systems with up to 7 energy star ratings. That’s efficiency at it’s best.
Evaporative Cooling Does not dry your skin
As alluded to above, evaporative cooling uses water to cool air. And so the air generated naturally contains a higher percentage of moisture. This is good for skin and complexion. The more humid air does not dry the keratin layer of the skin as much as refrigerated air.
Prolonged exposure to evaporative cooled air, will hence not dry up the skin as much. This makes for a much more pleasant environment, and is also good for complexion in the long run. Want better skin? An evaporative system might be the way to go.
Whisper Quiet Operation
Again, due to the fact that evaporative air conditioning does not rely on refrigeration, it operates at very low noise levels. Much like how a refrigerator generates that whirring motor noise, refrigerative air conditioners also emit a similar noise, but at a reduced level. However, you can still hear it audible if the room is quiet.
Evaporative systemsm, however, are much quieter than wall split system and reverse cycle air conditioners. Almost at a whisper, you possibly won’t even hear the sound emissions, even if the room is quiet.
Evaporative Cooling Is Environmentally Friendly
Evaporative air conditioning is also the most evironmentally friendly system. It puts out 80% less CO2 emmissions than refrigerative systems. Again, this is a result of using water to cool, instead of a chemical based refrigerant. So if going Green is your thing, and if you love being environmentally friendly, evaporative cooling is your best option.
Is It Ideal For You?
So is evaporative air conditioning for you? It depends.
For home owners that want really crisp cold air, to cut through the heatwave on hot summer spells, then they may find the cooling from an evaporative air conditioner insufficient. Some people are just more comfortable with really cold air conditioning. For such, a natural breeze like that from an evaporative system, just does not cut it. And if your budget is not constrained and you are not so concerned about running costs, then a refrigerated wall split system or reverse cycle system may be best for your home.
However, if you would prefer more natural, breeze-like air, and to operate your air conditioning with your doors and windows open, then an evaporative air conditioner would be your choice. As mentioned above, many other benefits come with it. Namely lower running costs, air that is easier to breathe, and that is better for skin complexion. Not to mention, it is more environmentally friendly.
So just evaluate your own requirements and decide for yourself if you need evaporative air conditioning.
Just How Efficient Is Evaporative Cooling
Seeley International, the 100% owned Australia manufacturer that produces the Breezair brand, says an evaporative system could cost as little to run as a light bulb. As you can see from the above running cost comparison chart, an inverter equipped ducted evaporative system (far right) could run at 80-90% cheaper costs than a ducted air conditioner (far left).
That translates to a monetary saving of close to $346 per year. So how does an evaporative system achieve such low levels of power consumption? It goes back to the science behind the system.
Evaporative Vs Refrigerative
The process of refrigeration consumes a lot more power than the evaporative process. Refrigeration uses a refrigerative coolant to produce cooling. This coolant requires electricity to super cool itself to a temperature whereby it can cool air that comes into contact with it.
Refrigeration consumes more power, but is able to produce air that is much colder and crisp. Most air conditioning systems today are refrigerative systems. They function similarly to how a conventional refrigerator works.
An evaporative system uses the natural process of evaporation to cool air. There is no refrigerant used. Warm air is passed through damp cooling pads, and the water in those pads naturally cools the air. The air generated is not as cold as in refrigerative systems, but is cooled sufficiently to produce a comfortable level cooling for a home.
Although not as cold, the evaporative air conditioner can still sufficiently cool a home and produce a very comfortable climate. The air would be like a natural cool breeze, that’s high in moisture content, easier to breathe and gentler on the skin.
Scientifically, the process of evaporation requires far less energy than refrigeration. With the advent of inverter technology incorporated into recent models of Evaporative air conditioners, the efficiency is improved even more.
If running cost is an important consideration for you, you would definitely want to consider installing an evaporative air conditioner. It is hands down the cheapest to run.
Evaporative – Other Costs
Although Evaporative consumes a lot less electricity, there are other implied costs associated, if you go with an evaporative setup.
Firstly, evaporative uses water. Albeit that the water consumption is fairly low, about 5,400+ litres a year, it still is a running cost. To put things in perspective, an evaporative air conditioner would consume slightly less water per year, than a dishwasher.
Of course, how much water is used also depends on the frequency of usage, or how long and how often you turn on the evaporative air conditioner.
Besides water consumption, you would also need to install separate heating for your home. An evaporative air conditioner does not produce warm air and hence does not provide heating for a home. Unlike a reverse cycle air conditioner.
You could go with a standalone wood heater or wall furnace, but those are just space heaters. You provide effective heating for an entire home, most owners would opt for a ducted gas heating system. These can deliver warm air throughout a home of any size.
A ducted gas heating system uses gas to power it’s heating. Although gas comes at a lower price tag than electricity, it is still a cost. And in recent years, the cost of gas has increased somewhat.
So when considering an evaporative air conditioner, you need to work in the cost of gas (if you going for the evap/gas heating combo) and water. Add these costs up with the cost of running an evaporative system, and you would have a meaningful comparison against a ducted or split system reverse cycle air conditioner.
Depending on your usage model and how often you use your home heating and cooling systems, upfront and running costs may vary. And it is important to carefully calculate your running costs, before you decide on which type of system to install.
