THREE PHASE vs SINGLE PHASE POWER SUPPLY; WHAT’S THE DIFFERENCE?
Most modern homes have a single phase power supply. If you have a swimming pool, workshop, an existing air conditioning system or an older home, you may have three phase power supply. In years past three phase air conditioners were considered to be the most reliable, cost efficient and only option if you required a large system. Today, most quality domestic air conditioning systems are inverter type and these only require single phase power supply, but can also be connected to homes with three phase. Today’s inverter systems are quieter, more energy efficient, reliable and the smart choice for consumers.
DO I NEED THREE PHASE POWER?
No. Since the introduction of inverter technology, domestic size air conditioning systems only require single phase power.
IF I HAVE THREE PHASE POWER, DO I HAVE TO GET A THREE PHASE SYSTEM?
No. Since the introduction of inverter technology, there is no longer any advantages to having a three phase system. The power input for both the single and three phase are exactly the same, so there is no difference in running costs. Pre inverter technology, three phase compressors were more reliable and lasted longer, but again since the introduction of inverter technology, this is no longer the case.
DO I NEED CONSTANT (DUMP) ZONES?
No. Advantage Air’s sophisticated zone control system (Zone 6 / MyAir / E-Zone) safely eliminates the need for a constant, or ‘dump’ zone. As Advantage Air states – “Their clever system monitors how many zones are closed and automatically opens and closes a preselected dump zone only when needed. In standard systems, the solution is to have a dump zone (or constant zone), which remains open at all times. The dump zone can occupy up to 25% of your home and it will receive conditioned air irrespective of whether you’re using that room or not. Why blow money on air-conditioning more rooms than you need to?”
HOW MANY ZONES DO I NEED?
We highly recommend having each room zoned individually, giving you flexibility controlling which rooms receive air at any time and to save energy by only running the air-con in rooms you are using. Why pay to cool or heat areas that you are not using?
DO I NEED TWO RETURN AIR GRILLES?
Most homes only require one. The return air grille is where air from your home is sucked through a filter to be cooled/heated and then pumped back out through the supply air outlets. It is usually installed in a hallway or central area of the home and is the largest visible part of the system inside your home. Most homes only require one return air grille. If you wish to close doors tightly, or shut off the area that the return air grille is in, you may need to consider an additional return air. Please speak to us clarify any special circumstances or requirements for your home.
IF I REPLACE MY EVAPORATIVE UNIT WITH A REVERSE CYCLE SYSTEM, CAN I RE USE ANYTHING?
Unfortunately, no. One main reason for this, among a few, is that the two system types work on different air volumes, so evaporative duct work will need to be changed over to suitable refrigerated duct work & fittings.
CAN I RUN JUST ONE ZONE?
It is recommended to always have a minimum of two (2) outlets running at any one time. For e.g. a zone with two (2) or more outlets can be used independently. Single (1) outlet zones i.e. bedrooms, you will need to run at least two (2) rooms.
CAN I RUN THE WHOLE HOUSE AT ONCE?
Yes you can, but this will be dependent on the outside ambient temperature at that time. I.e. a ducted air conditioning system will, most likely, not be capable of cooling the whole home in the hottest part of the day. This is why they are installed with individual zones, to allow the user flexibility selecting which rooms to run depending on demand and environmental conditions. Generally a system will cool around half the house in the hottest part of the day and this area increases at night, once the outside temperature becomes less extreme.
It would be cost prohibitive to install a system capable of cooling a whole home on a 48 degree day. Essentially, you would be doubling the cost of installation and your ongoing running costs just for the sake of a few days of the year.
WHERE SHOULD I LOCATE THE OUTDOOR UNIT?
Typically, the outdoor unit will be located on the least used side of the house, taking into account access/neighbour’s/location to meter box/customer preference/other appliances etc. However, we will always confirm the location in consultation with the client.
