Good insulation in your home will help reduce running costs for both systems.
Evaporative cooling vs refrigerated cooling melbourne.
Unlike refrigerated air conditioning evaporative cooling air conditioning is based on a totally natural cooling process so there are no harmful refrigerant gases.
With evaporative cooling systems fresh air is constantly being pulled in from outside filtered cooled and then circulated through your home.
The refrigerated air conditioning system on the other hand requires a lot of power to maintain the refrigerated cooler.
The air is never re circulated it s always fresh and clean so stale air isn t an issue.
Cool your entire home from as little as 5 cents per hour.
I am in canberra and building a new house.
Not only that but ducted heating is less effective the higher the humidity is.
It is also 50 cheaper to install and up to eight times cheaper to run than refrigerated cooling.
Ducted refrigerated air conditioning is effective in all weather conditions including humidity making it perfect for melbourne s 4 seasons in one day.
By a long shot.
With refrigerated cooling the air is recirculated.
Refrigerated cooling gives a better result but will have higher running costs.
About 8ml of water per cubic meters of air considering 1 m 3 is approx 1 2kg.
While there are ways to minimise this cost such as solar power.
Hands down evaporative coolers are cheaper to run than refrigerated systems.
Compared to the specialised refrigerants found in refrigerated air conditioning water is less effective at removing heat from the air.
Namely evaporative cooling is less powerful than refrigerated.
I know the topic of refrigerated vs.
An evaporative cooling system needs to be connected to a constant water source to work.
Therefore on a 30 rh day you are adding about 50 humidty.
Evaporative cooling 2.
Refrigerated cooling benefits cooling in all weather conditions.
We have to give point 2 to e.
Refrigerated cooling is arguably more reliable and effective but it s going to mean a bigger electricity bill during those sticky summer months.
Since evaporative coolers works through a fan and water pump it uses much less power than most cooling systems.
Evaporative cooling raises humity in the house to about 80.
You can guesstimate from the graph below that on a 35 degree day with 30 rh this equates to about 10ml or grams of water per kg of air.
Evaporative cooling is easily the cheaper option and can be up to 50 per cent cheaper to install and more than seven times cheaper to run.
While most homes do have reliable water systems it s understandable that not everyone will be able to provide an evap cooling unit with the right amount of water.
Unfortunately that comes with a trade off.
It includes both heating and cooling which means you only need to install one system.
