HOW INVERTER AIR CONDITIONERS WORK
Think of the inverter air conditioner as a car driving along a highway. Before you take off your sitting in your car at a stand still. When your ready to go, you put your foot on the accelerator and steadily go faster and faster until you reach your desired speed.
Once you are there you ease your foot off and cruise along at a constant speed, lightly pressing down on the accelerator. Only pressing down a little more when you need to compensate for a slight incline or headwind coming straight at you. The engine works much less and uses less fuel.
Then you hit a hill and you find yourself pressing down on the accelerator harder using more and more of that expensive energy called petrol.
You probably never even think of it in those terms when you drive your car. How any form of resistance in the forward momentum of your car is actually chewing through the money that was just in your wallet or purse.
The only time you think about the money you spend running your car is when you stand at the counter and hand over hard earned cash,or worse….your credit card!
Inverters work in much the same way.
Inverter air conditioners are the same.
They speed up and slow down as the system needs it to, for it get to the desired temperature. Once they hit their speed they can make slight adjustments in their output to compensate for changes in temperature throughout the day, whether in heating or cooling mode. All the time trying to keep the input power required to a minimum.
Conventional air conditioners are the equivalent of getting in your car and planting your foot for a few KM’s and then taking your foot off, planting your foot for a few KM’s and then taking your foot off,planting your foot right down HARD for a few KM’s and then taking your foot off, rinse – repeat!
The above diagram shows how an inverter air conditioner works. When it is turned on it will quickly get to the desired temperature and then back it’s self off just to maintain the temperature you want.Inverter air conditioners convert the AC power input into DC to allow the control of the compressor speed in the outdoor unit. This gives the air conditioner control over power consumption and greater accuracy in consistant temperature.
Inverter units are,
- Much more reliable in extreme temperatures.
- Keep temperature constant (no fluctuations with room temp going up and down).
- Cost up to 30% less in electricity bills.
- The inverter air conditioner has less wear and tear on it (which can lead to a much longer life span)
- Are much quieter than non-inverters
HOW NON-INVERTER UNITS WORK
Now imagine the same scenario, except once you reach your desired speed you take your foot completely off the accelerator and let the car slowly lose speed until you are at 60kph then speed back up to 100kph then slow back down to 60kph then speed back up…….. get the idea?
A stop and start motion slows down your ability to get where you are going and is seriously annoying!
Diagram is a guide only – actual temperature values WILL vary depending on things like your desired temperature (20 degrees) compared to, outside temperature, time of day, insulation, blinds, correct installation.If you really want to research more about the efficiency of air conditioners check out the following link.

If not, keep searching for air conditioners online and stick to the major brands, you can’t go wrong!
Non-inverter units will eventually be phased out as part of the shift to more efficient ways of heating and cooling. Don’t spend money on a unit that will be considered out of touch and out of date very soon and will cost you a fortune to run
This short video shows how inverter air conditioners work also.
So do your self, and the environment a favour and make sure you purchase a high efficiency inverter air conditioner. The last thing you want is to worry about how much your air conditioner is going to cost to run when you need it most.
