What Is Split Air Conditioner?
A Split System air conditioner has two components, an indoor and outdoor unit. The indoor unit absorbs heat, while the outdoor unit cools and pumps cold air into the indoor unit. The two units are connected by insulated tubes which are piped through a small hole in the wall.
How To Install A Split System Air Conditioner?
Split system air conditioners require installation by licensed professionals to safely handle gas refrigerant, conduct electrical wiring and plumbing into your home’s storm water system.
The outdoor unit is fitted on the exterior wall of the room that requires cooling. The indoor unit is then mounted on the wall in the room. Generally speaking, it’s better to install the air conditioner on a long wall of the room and not directly above a window.
Installing a split system air conditioner usually takes about half a day.
How Does A Split System Air Conditioner Work?
A split system air conditioner works by pumping refrigerant gas through the unit’s cooling circuit. As the gas pumps through the condenser, it cools down and vaporises into a liquid. The liquid refrigerant is then pushed into the evaporator, expanding and changing back into a gas. As the gas rapidly expands, the temperature drops dramatically. The gas then passes back to the condenser to repeat the process.
Air from the room is drawn into the unit and passes over the evaporator coils, which cools the air. The cooled air is blown back into the room. The air continues to circulate until the desired temperature (set by the thermostat) is reached. When the desired temperature is reached, the unit shuts down automatically.
What Size Split System Do I Need?
Choosing the right size air conditioner is extremely important to maximise performance and minimise running costs. Air conditioners that are too big will use more energy, while air conditioners that are too small will not cool the room sufficiently.
The four biggest things that impact the size of the split system you need include:
- Room size
- Insulation
- Location
- Orientation
Room size
Floor space and total volume of the room are one of the most important factors in determining the size of the air conditioner you will need. Rooms with higher ceilings will require more energy to cool.
Generally speaking, the following applies:
A 10m2 to 20m2 room will need a 2.6kW unit
A 20m2 to 30m2 room will need a 3.5kW unit
A 30m2 to 45m2 room will need a 5-6kW unit
A 45m2 to 65m2 room will need a 7-8kW unit
However, it’s always a good idea to seek expert advice before making a decision.
Insulation
Ceiling insulation is one of the biggest factors in making your home thermally efficient. High quality insulation will help retain the cold air, helping your air conditioner run more efficiently and cost-effectively.
Location
Australia’s climate is so diverse. If you live in Darwin, you will need a much more powerful air conditioner compared to Hobart.
While we don’t get freezing cold or boiling hot temperatures here in Newcastle, we recommend reverse cycle split system air conditioners to provide you with ultimate comfort all year round.
Orientation
Which way does the room face? A large north or west-facing window can let in a lot of heat in summer, whereas a shaded, south-facing window will be a lot cooler.
How Many Years Does A Split AC Last?
15 to 20 years
Most split-system air conditioning (AC) units are designed to have a long lifespan of 15 to 20 years when well maintained.
