With evaporative cooling systems fresh air is constantly being pulled in from outside filtered cooled and then circulated through your home.
Evaporative cooling vs refrigerated cooling melbourne.
Ducted refrigerated air conditioning is the most premium form of air conditioning available.
While there are ways to minimise this cost such as solar power.
Compared to the specialised refrigerants found in refrigerated air conditioning water is less effective at removing heat from the air.
Not only that but ducted heating is less effective the higher the humidity is.
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.
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.
Refrigerated cooling gives a better result but will have higher running costs.
Therefore on a 30 rh day you are adding about 50 humidty.
Good insulation in your home will help reduce running costs for both systems.
Since evaporative coolers works through a fan and water pump it uses much less power than most cooling systems.
About 8ml of water per cubic meters of air considering 1 m 3 is approx 1 2kg.
In terms of environmental factors both systems use electricity but evaporative also uses water.
Evaporative cooling 2.
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.
I am in canberra and building a new house.
Unfortunately that comes with a trade off.
Hands down evaporative coolers are cheaper to run than refrigerated systems.
The refrigerated air conditioning system on the other hand requires a lot of power to maintain the refrigerated cooler.
By a long shot.
Cool your entire home from as little as 5 cents per hour.
Refrigerated cooling is arguably more reliable and effective but it s going to mean a bigger electricity bill during those sticky summer months.
I know the topic of refrigerated vs.
Evaporative cooling raises humity in the house to about 80.
Ducted refrigerated air conditioning is effective in all weather conditions including humidity making it perfect for melbourne s 4 seasons in one day.
Unlike refrigerated air conditioning evaporative cooling air conditioning is based on a totally natural cooling process so there are no harmful refrigerant gases.
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.
With refrigerated cooling the air is recirculated.
Namely evaporative cooling is less powerful than refrigerated.
Refrigerated cooling benefits cooling in all weather conditions.
It includes both heating and cooling which means you only need to install one system.
It is also 50 cheaper to install and up to eight times cheaper to run than refrigerated cooling.
