So what’s the secret behind an Energy Efficient Ducted System?

Check out the following video here!





“There are many reasons why Morphett Air Conditioning has elected to recommend and sell Daikin Air Conditioning equipment over the last 15 years or so including their performance and reliability under “extreme temperatures”, whisper quiet noise operating levels as well as their high levels of efficiency.


Did you know that many alternative brands of air conditioners are only guaranteed to perform normally under certain temperature conditions?  That’s right and you’d be surprised at what temperatures!  In many cases most units are only guaranteed to function normally when the outside temperature does not exceed 38°c in Summer!
In Winter, most units are only guaranteed to function normally when the outside temperature does not exceed 3°C (or even 5°C in some cases!)


So what we’re really saying here is that while the temperature is between 3°C – 38°C all is ok but the minute it gets colder than this or hotter than this you are in real strife!
With Daikin air conditioning however, it’s a different story.


Daikin Inverter Ducted air conditioning systems can handle extreme temperatures and has certified operation in temperatures from a freezing -15°C in heating to a scorching 46°C in cooling!!

The Daikin Inverter Outdoor Ducted units benefit from significant advances in technology making quieter operation possible.



DC Sine-Wave Inverter smoothes the motor rotation resulting in a definite reduction in noise, and a much greater energy efficiency.



Hybrid Aerofoil Fan.  High-Flared Bell Mouth. Super Aero Grille.
A recently designed fan, with an improved air flow analysis technique developed by NASA, plus other advanced features, provides smoother and quieter air flow while at the same time offering a greater reduction in power consumption.



In Night Quiet mode, the speed of the outdoor fan and compressor can be timer operated or automatically reduced when the unit deduces that it is night time.  Pretty clever huh?  This will ultimately provide quieter night time operation so you and (your neighbour) can sleep easy.




Daikin Inverter Air Conditioners are extra efficient and use considerably less energy than non-inverter, conventional units.


Daikin’s advanced technology is incorporated into a number of the inverter ducted’s components resulting in significantly lower engery costs.


Daikin received the Japanese Electric Science and Promotion Prize for its innovative design.  More powerful neodymium magnets in the Reluctance DC Compressor help generate more power using less energy.  Outstanding energy savings are achieved, particularly when operating in the lower speed zone.

Daikin’s advanced compressor designs achieve further energy savings in both Swing Compressor (71 class) and the latest Scroll Compressor (100 – 160 class).  The Swing Compressor reduces friction and leakage of refrigerant while the Daikin Scroll Compressor has been redesigned to provide even greater efficiencies than conventional scroll compressors.


Optimum efficiency is achieved with Daikin’s Cross Pass Heat Exchanger that divides the refrigerant flow into two circuits.  The coil structure together with the properties of the R410A refrigerant are improved and the heat transfer efficiency enhanced.

“So what is the difference between Inverter and Fixed Speed compressors?”

The term “Inverter” is one that is thrown around a lot these days but not many people completely understand the term and how it works.


Fixed Speed Compressor :


In days gone by, before Inverter technology didn’t have any other option than to have a “fixed speed” compressor in our air conditioners.  The term “fixed speed” simply means that when you turn on your air conditioner, the compressor jumps into action and runs at a constant speed until the room reaches the desired temperature. Once the temperature is met, the air conditioner compressor turns off (or cuts out) until the room temperature is noticeably different and enough that the air conditioner recognizes the change in temperature and jumps back into action again to bring the room temperature back to the desired temperature.


In other words, this type of compressor is considered a “START and STOP” type compressor (ie either it’s ON or it’s OFF).


The disadvantage of the “start/stop” compressor is exactly that.  There is no in between and the compressor is either running flat out or it’s off.


One of the side effects of the starting and stopping action is that the room temperature often fluctuates enough for the air conditioner to recognize the change and for the user, this means that you could potentially be feeling too hot and too cold.


While the other effect is that when the compressor initially jumps into action there is often a large amperage draw which will ultimately mean more running costs.  (This is sometimes evident when the compressor first starts your lights will momentarily dim.)

Inside a Super Inverter



Daikin’s Super Inverter Outdoor Ducted units benefit from significant advances in technology.


This quiet operation is possible because of innovative design improvements to key components.

  1. Reluctance DC Compressor generates more power using less electricity.
  2. DC Sine-Wave Inverter smooths the motor rotation resulting in definite reduction in noise and much greater efficiency.
  3. Heat-divide type heat exchanger: The area of heat exchanging is widened to improve efficiency.
  4. New Super Cooling circuit
  5. DC Fan Motor
  6. Compressor Linked Fan control
  7. Hybrid Aerofoil Fan, high-flared bell mouth, and super aero grille: a newly designed fan, with improved air flow analysis techniques developed by NASA, provides smoother air flow while at the same time offering a greater reduction in power consumption.
  8. Intelligent precise temperature control

So what’s so special about Inverter technology?


In more recent times we tend to be more concerned with energy efficiency and running cost savings and Inverters helps us in both of these areas.


Where a fixed speed compressor is a START/STOP principle, the Inverter compressor starts off extremely slowly (and therefore the amperage draw upon start up is extremely low).  As the air conditioner senses the temperature in the room and compares that with the desired temperature set by the user, the air conditioner then decides how hard it needs to run in order to achieve the desired temperature.


So let’s assume for a moment that you have pre set your desired temperature on Cooling and 23°C.  The air conditioning system senses that the room temperature is definitely a lot warmer than this so it sends a message to the compressor to start.


The compressor will start but at a very slow capacity and speed.  The compressor will then gradually increase its capacity and speed to a point where the temperature in room reaches the desired temperature (in this case 23°C).


Once the desired temperature has been met, unlike the fixed speed type the compressor will not just turn off at that point.  Instead the compressor capacity and speed will gradually start to decrease to a point where the unit is running at a much lower capacity.


If the room temperature starts to increase or decrease, then the unit will sense the change and will increase or decrease the conditioning process slightly to accommodate the change in temperature.


A comparison of this principle could be compared with that of the accelerator of a car.  When you initially put the car into drive and put your foot on the accelerator you increase the cars speed gradually until you reach a cruising speed of say 60km per hour.  Once you’ve reached the desired speed you then only need to touch the accelerator in order to maintain the cruising speed.


“So what are the benefits?”


Firstly, because the unit is continuously adjusting the capacity and speed to accommodate the room temperature changes, the room temperature tends to be a lot more consistent (as seen in the diagram below).


Secondly, providing the unit is sized correctly (see our online calculator to assist) the unit will not be working as hard to maintain the desired temperature and therefore is far more cost effective to run compared with that of the fixed speed type.  Again the critical key here is to ensure that the unit capacity (ie kW or HP) must be sized correctly in order to see any running cost savings.


For example, if the Inverter unit was undersized for your home it would be running at a much higher capacity and speed for longer and would not get the opportunity to slow itself down.  In this case you would be lucky to see any cost benefits at all!

From the 1st of October 2001, ducted and non ducted air conditioners of the vapour compression type with a cooling capacity of up to 65kW manufactured in or imported into Australia and New Zealand, are required to comply with the Minimum Energy Performance Standards (MEPS) limits.  These requirements are set out in Australian and New Zealand Standard 3823.2-2001.


Since then MEPS levels have progressively increased and on the 1st of October 2007, increased MEPS levels came into force.


Today, developed countries like Australia are turning to MEPS to increase the overall efficiency of air conditioners in the marketplace.


Daikin is committed to providing air conditioning solutions that are energy efficient, quiet, simple to use and reliable, ensuring our units not only meet MEPS requirements but in most cases exceed the minimum requirements.
