One of the most common misconceptions made by customers seeking air conditioning in Cairns is that the bigger the AC unit, the better the cooling.
Air Conditioning experts know this is not the case and we will explore the reasons why, as well as a few ways to work out the right size system for your space.
Modern air conditioning systems operate by cooling the room in slow cycles, gradually lowering the temperature to the desired level.
When the cycle finishes, the machine will shut off until the space warms past an acceptable level.
Then the cycle will kick in and slowly cool the space again.
If you install an air con that is too large, the room will rapidly cool as the unit blasts out cold air.
Once the correct temperature is reached, the cycle will end prematurely.
The cool air will quickly warm, starting the cycle all over again.
As you can imagine, this loop of switching on and off constantly will waste unnecessary power and leave you with a nasty shock when the electricity bills arrive.
If bigger is bad, smaller doesn’t solve the issue either.
You may now be thinking that a small system will do the job and will have a cheaper initial outlay.
The unit may be more cost effective when you first have it installed but that effectiveness evaporates over time.
If a system is not big enough for your space, it will have to run all the time in order to bring the temperature down.
If the room is way too big for the little chiller, it might not be able to reach the desired temperature, even if it’s going at full blast.
This means it will never complete its gradual cycle and run all day long.
Even though the unit is small, it will still draw lots of energy if it operates at 100% and this will cost you in the long run.
If you are installing ducted air conditioning in Cairns, you can calculate the area of the rooms that will be cooled by measuring the length and width of each room and multiplying them e.g. 10m x 10m = 100m².
Then add all the rooms together e.g. 100m + 100m + 100m = 300m².
Next you can measure your ceiling height which should be a minimum of 2.4m.
If it is 2.4m, multiply the floor area by 150 watts e.g. 300m² x 150 = 45000 watts.
If the ceiling is 2.7m, times by 160 watts or if it’s 3m, multiply by 175 watts.
Divide your answer by 1000 to get the kilowatt (kW) output you need e.g. 45000 ÷ 1000 = 45 kW. Easy as that!
