In terms of environmental factors both systems use electricity but evaporative also uses water.
Evaporative cooling vs refrigerated cooling melbourne.
Since evaporative coolers works through a fan and water pump it uses much less power than most cooling systems.
Namely evaporative cooling is less powerful than refrigerated.
Evaporative cooling has been discussed many a time but i am now in the situation where i need to choose and am interested in specific information on running costs.
By a long shot.
Evaporative cooling 2.
Unlike refrigerated air conditioning evaporative cooling air conditioning is based on a totally natural cooling process so there are no harmful refrigerant gases.
While there are ways to minimise this cost such as solar power.
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.
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.
We have to give point 2 to e.
Unfortunately that comes with a trade off.
With evaporative cooling systems fresh air is constantly being pulled in from outside filtered cooled and then circulated through your home.
With refrigerated cooling the air is recirculated.
Refrigerated cooling benefits cooling in all weather conditions.
I am in canberra and building a new house.
It includes both heating and cooling which means you only need to install one system.
Compared to the specialised refrigerants found in refrigerated air conditioning water is less effective at removing heat from the air.
Cool your entire home from as little as 5 cents per hour.
Refrigerated cooling gives a better result but will have higher running costs.
The air is never re circulated it s always fresh and clean so stale air isn t an issue.
Evaporative cooling raises humity in the house to about 80.
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.
An evaporative cooling system needs to be connected to a constant water source to work.
Ducted refrigerated air conditioning is the most premium form of air conditioning available.
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.
Therefore on a 30 rh day you are adding about 50 humidty.
The refrigerated air conditioning system on the other hand requires a lot of power to maintain the refrigerated cooler.
About 8ml of water per cubic meters of air considering 1 m 3 is approx 1 2kg.
Ducted refrigerated air conditioning is effective in all weather conditions including humidity making it perfect for melbourne s 4 seasons in one day.
Hands down evaporative coolers are cheaper to run than refrigerated systems.
