What is split system air conditioning?

The benefits of split system air conditioners for Australian homes.

When it comes to cooling and heating Australian homes, choosing the right air conditioning system can make a significant difference in comfort, efficiency, and cost.

Among the various options available, split system air conditioners stand out as a versatile and effective solution. In this article, we will explore what split system air conditioners are, how they work, and why they can be a better choice compared to ducted air conditioning systems.

What exactly is a split system air conditioner?

What exactly is a split system air conditioner?

A split system air conditioner consists of two main components: an indoor unit and an outdoor unit. The indoor unit, typically mounted on a wall inside the room to be cooled or heated, contains the evaporator coil and a fan to circulate the air. The outdoor unit, placed outside the home, houses the compressor, condenser coil, and another fan. These two units are connected by refrigerant pipes and electrical wiring.

How does a split system air conditioner work?

How does a split system air conditioner work?

The operation of a split system air conditioner involves several key steps:

  1. Refrigerant Circulation: The refrigerant, a special fluid, circulates between the indoor and outdoor units. When the system is in cooling mode, the refrigerant absorbs heat from the indoor air as it evaporates in the indoor unit's coil.
  2. Heat Transfer: The absorbed heat is then transported to the outdoor unit, where the refrigerant releases the heat as it condenses in the outdoor coil. This process cools down the refrigerant, which is then cycled back indoors to absorb more heat.
  3. Air Distribution: The indoor unit's fan blows air over the cool evaporator coil, lowering the temperature of the air before it is distributed throughout the room. In heating mode, the process is reversed, with the refrigerant absorbing heat from the outside air and transferring it indoors.

How much do split system air conditioners cost?

How much do split system air conditioners cost?

While the initial installation costs are higher compared to purchasing a portable air conditioner, split-system air conditioners are highly efficient and relatively affordable to install, especially when compared to ducted systems. This makes them one of the most cost-effective choices over time.

The overall cost will be influenced by the price of the units you choose and the installation fees charged by the technician. Prices for split-system air conditioners can vary significantly, ranging from $500 to $5000, depending on several factors:

  • Brand and Model: Different brands and models come with varying price tags.
  • Size and Capacity: Measured in kilowatts, the required size and capacity of the unit will affect the cost.
  • Smart Features: Advanced features like sensors, eco modes, Wi-Fi, and app compatibility can increase the price.
  • Seasonal Timing: Prices may be lower during off-peak seasons.

Why choose a split system air conditioner over a ducted system?

1. Energy Efficiency

Split system air conditioners are highly efficient, especially when used to cool or heat specific rooms. Unlike ducted systems, which can lose efficiency due to duct leaks and the energy required to cool or heat the entire house, split systems allow for targeted temperature control. This means you can cool or heat only the rooms you are using, leading to significant energy savings.

2. Cost-Effective Installation:

The installation of a split system air conditioner is generally less expensive and less invasive compared to ducted systems. There is no need for extensive ductwork, which can be costly and disruptive to install. This makes split systems an ideal choice for retrofitting existing homes or adding air conditioning to specific areas.

3. Flexibility and Zoning

Split systems offer greater flexibility in terms of placement and zoning. You can install multiple indoor units connected to a single outdoor unit, allowing you to create different climate zones within your home. This level of control is particularly useful in homes with varying cooling and heating needs across different rooms.

4. Aesthetics and Space-Saving

Split system air conditioners are sleek and unobtrusive, with indoor units that blend seamlessly into the décor of any room. Split systems take up less space compared to ducted systems, which require a network of ducts hidden within walls and ceilings.

5. Quiet Operation

Split systems are known for their quiet operation. With the noisy compressor located outside the home, the indoor units operate quietly, providing a comfortable environment without the distraction of constant noise.

6. Easy Maintenance

Maintaining a split system air conditioner is relatively straightforward. Regular cleaning of the filters and occasional servicing of the indoor and outdoor units can keep the system running efficiently. In contrast, ducted systems may require more extensive maintenance due to the complexity of the ductwork.

What are the pros and cons of reverse cycle split system air conditioning?

Pros

  • Energy Efficiency Allows for targeted cooling and heating of specific rooms, reducing overall energy consumption. Minimizes energy loss compared to ducted systems, which can suffer from duct leaks.
  • Cost-Effective Installation Generally less expensive to install than ducted systems due to the absence of extensive ductwork. Ideal for retrofitting existing homes or adding air conditioning to specific areas.
  • Flexibility and Zoning Multiple indoor units can be connected to a single outdoor unit, allowing for customized climate zones. Provides precise temperature control in different rooms, catering to varying cooling and heating needs.
  • Aesthetics and Space-Saving Indoor units are sleek and unobtrusive, blending seamlessly into room décor. Requires less space compared to ducted systems, which need a network of hidden ducts.
  • Quiet Operation With the noisy compressor located outside, indoor units operate quietly, creating a peaceful indoor environment.
  • Easy Maintenance Regular cleaning of filters and occasional servicing of units keep the system running efficiently. Less complex maintenance compared to ducted systems.

Cons

  • Limited Capacity Each unit typically covers a single room or a limited area, which might require multiple units for larger homes. Less efficient for cooling or heating entire large homes compared to ducted systems.
  • Outdoor Unit Placement Poorly designed ducted zoning systems can increase running cost when compared to single room solutions.
  • Aesthetic Concerns Indoor wall-mounted indoor units might not suit all interior designs. Requires careful placement to ensure optimal performance and aesthetics.
  • Maintenance Requirements Regular maintenance of multiple units can be costly. In some cases multiple filters need frequent cleaning to ensure efficiency and air quality.
