Split System Air Conditioning
Split system: Split systems are usually used to cool one or more rooms or an open-plan area. They provide better cooling than window and through-the-wall or portable air conditioners. However, they are more expensive and require professional installation. Split systems work by placing the cooling parts of the air conditioner outside and then having one or two inside parts that contain the fans.

Are there different types of split systems? Yes. There are two types:
- Conventional split systems
- Inverter split systems
The Inverter Spit Systems are the latest in engineering and are noticeably quieter and more reliable in the long term. Moreover, the inverter technology delivers up to 36% energy savings over conventional products.
Another comfort benefit of this technology is that they have eliminated the annoying initial surge of cold air on the heating cycle which is common to conventional high wall mounted splits.
A split system is an air conditioner which has two separate units making up the system – an indoor unit (evaporator), which is located inside the space being cooled or warmed and an outdoor unit (condenser) where the air from inside is rejected. The two units are connected by pipes which carry refrigerant.
A variation on the standard split system air conditioner is the multi-split system, which as multiple indoor units connected to a single outdoor unit. This allows the system to cool and warm multiple rooms.
Multi split system: Normally targeted for commercial use it is now becoming available to the consumer through commercial specialists and resellers. Similar to a split system, the multi split system provides cooling from two to nine rooms throughout the house from one outdoor air conditioner unit through to the indoor units. Unfortunately, this type of air conditioner makes it difficult to determine minimum efficiency performance (MEP) when the air conditioner is turned on in all rooms of a house.
Portable Air Conditioning
Portable: Portable air conditioners can be moved around and are much cheaper than other air conditioners. However, because of their small size and lower power output, they are not as good at cooling you down.
Inverter Air Conditioning
What is an inverter?
Through new, advanced technology, Inverter air conditioners are more economical to operate and quieter to run than conventional units. They can handle greater extremes in temperature, are smoother and more stable in operation and reach the desired temperature more quickly than conventional air conditioners.
Comfort and Stability
The air conditioner’s output is stabilised at the optimum setting within the range from maximum to minimum to match the load, which is affected by factors such as the room temperature and the number of people present.
High Efficiency Technology
Significantly higher efficiency is realised by using DC twin rotary compressor, DC inverter control and DC fan motor technologies.
Panasonic Inverter technology
Panasonic Inverter technology delivers substantial energy savings, to benefit the environment and your power bill. The Inverter allows up to 50% energy savings during cooling operation and 64% energy savings during heating. This revolutionary technology provides a more even room temperature, as it does not need to be constantly turned on and off. This means that the desired room temperature you set on the remote control will be maintained at all times, providing constant comfort all year round.
How Reverse Cycle Air Conditioners Work.
An outdoor compressor unit compresses liquid into a gas state to allow the refrigeration effect to take place; the same way as your home refrigerator. The compressed gas is transferred through the connecting copper pipe installed inside your home or ceiling space. An indoor unit/console basically consists of a fan and a coil. The fan is connected and then controlled by a room installed thermostat that draws the air from inside the home, passing it through a filter and then recirculates throughout your home approximately 10 times each hour.
Ducted reverse cycle air conditioners cool or warm air in a room to a set temperature; controlled by a touch pad or remote control and can be controlled per room or ‘zone’.
There are three main types of compressor technologies used in refrigerative systems:
- Standard technology where the compressor is switched on and working at 100% capacity. When no cooling is required the compressor is switched off.
- Inverter technology where the compressor is always on but the operating speed will increase or decrease according to how much cooling power is required. Inverter technology can be more energy efficient than standard technology.
- Digital scroll technology, which is an alternate technology to inverter control. It also gives a variable output and energy consumption, but maintains a constant compressor speed. This technology is only used in larger ducted systems.
Streamline Air Conditioning and Refrigeration Central Coast and Newcastle can help you come up with the right ducted reverse cycle air conditioner for your home by looking at the following range of factors:
- Your home’s floor plan: How many levels are there? What are the dimensions of the rooms (including ceiling height)? Which direction do the rooms face?
- The size, position and orientation of windows and doors.
- The type of construction (for example, weatherboard or full brick).
- The level of insulation.
- The number of people living in your home.
- The main use of the area (for example, sleeping, living, cooking).
- The ceiling cavity space – slimline systems are available for homes with small ceiling spaces.
- Outdoor spaces – just as with split system air conditioners, the outdoor compressor unit(s) needs to be installed somewhere where noise won’t be an issue (for you or your neighbours).
- Large systems may require a three-phase power supply, which will be an extra installation cost if you don’t already have it.
This is why you should never buy such a system “off-the-shelf”; Streamline Air Conditioning and Refrigeration Central Coast and Newcastle branches will design a system for your unique, individual situation.
Features of a Reverse Cycle Air Conditioner.
There are several design features to consider. Streamline air conditioning central coast & Newcastle are able to offer a range of options, depending on the design and requirements of your home. These include:
- Vents come a variety of designs and can be installed in the ceiling or walls.
- Controls are usually hard-wired and mounted on a wall, unlike the remote controls used for single split-systems. You may have one controller for the entire system, but in a large house you might opt for extra controllers in other parts of the house for more convenience.
- Sensors are used by the controller to keep the room at the targeted temperature. Large open-plan areas may need multiple sensors.
- Most systems allow for a home to be divided into zones for convenience and economy, so that you can turn on the air conditioner for only the part of the house you want cooled/heated (say, living areas, bedrooms, or different floors) rather than the whole house. Or, you can set different climate levels for different areas as required.
The ducting is a key component of any reverse cycle air conditioning system. Ducts need to be thermally efficient so that valuable cooling or heating isn’t lost between the air conditioner unit and the target room. Streamline air conditioning central coast & Newcastle will only install ducting that meets or exceeds the Australian standard for duct work, AS 4254.
