Types of Split-System Air Conditioners
Split-system air conditioners are versatile and come in various configurations to cater to different needs and spatial constraints. Here are the main types of split-system air conditioners.
- Wall-Mounted Split Systems: The most common type of split-system AC. Consists of an indoor unit mounted on an interior wall and an outdoor unit placed outside, usually on the ground or a wall bracket. They are suitable for cooling or heating one room or a specific area.
- Floor-Mounted Split Systems: Similar to wall-mounted systems but installed at floor level. We recommend them when wall mounting is not feasible. They are typically used in spaces with large glass areas or limited wall space and are often larger in size and capacity than wall-mounted systems.
- Ceiling Cassette Split Systems: The ceiling cassette split systems have the indoor unit mounted on the ceiling, with only the decorative fascia visible. Allows for a more even distribution of air due to its central location. Suitable for larger rooms or open-plan areas.
- Ducted Split Systems: Provides cooling or heating to multiple rooms using ductwork installed in the ceiling or under the floor with a larger central unit situated in the roof space or outside. Air is distributed through vents in each room, allowing for whole-home climate control. Most ducted split systems have zoning capabilities, enabling different temperatures in different rooms.
- Multi-Split Systems (or Multi-Head Split Systems): These systems allow multiple indoor units to be connected to a single outdoor unit. They offer the flexibility to cool or heat multiple rooms with different temperature settings. We recommend them for homes or buildings where space for multiple outdoor units is limited.
- Ceiling Suspended Split Systems: In this system, indoor units are suspended from the ceiling and are ideal for spaces without suspended ceilings or free wall space. They are often used in commercial settings or large open-plan areas.
Qualities of Top Split-System Air Conditioners
When purchasing a split-system air conditioner, there are several important qualities to consider. We go over them below:
#1 - Energy Rating
In Australia, split-system air conditioners are required to carry an energy rating label. This label has a star rating, with a blue label for cooling and a red label for heating. The more stars an air conditioner has, the more energy-efficient it is.
#2 - Energy Efficiency Rating (EER)
The EER is a measure of an air conditioner's energy performance. It provides a ratio of useful cooling output (in BTU/h) to electricity input (measured in W). A higher EER rating means that an air conditioner will provide more cooling for every watt of energy you provide.
For example, an air conditioner with an EER rating of 12 means that for every 1W of energy provided to the air conditioner, you get 12 BTU of cooling effect. To calculate the EER rating, you must divide an air conditioner’s capacity by its power. Here's the EER equation to use:
BTU (British Thermal Unit) is a cooling capacity unit. When used for air conditioning systems, the measurement is expressed in terms of how many BTUs per hour the product can add or remove from the air. So, if an air conditioner has a rating of 12,000 BTUs, it means it's absorbing 12,000 British Thermal Units of heat each hour and moving it outside.
You can reduce your energy bill while using an air conditioner with simple tips like using a programmable thermostat. Check out more tips to reduce your air conditioning cost.
#3 - Cooling (and Heating) Capacity
Cooling and heating capacity refers to the ability of a split-system air conditioner to regulate the temperature in a room.
- Cooling Capacity: This measures an air conditioning system's ability to remove heat from a room, thus making the room cooler. It's essentially how much cold air the unit can produce per unit of time.
- Heating Capacity: This is the reverse of cooling capacity. It's the measure of the air conditioner's ability to remove heat from outside and transfer it into the room to improve cold temperatures.
Both capacities are measured in Kilowatts (kW) under the rated conditions specified in the official document: Australian/New Zealand Standard: Performance of electrical appliances – Air conditioners and heat pumps.
So, when you see a split system air conditioner with a specified cooling and heating capacity, it means that the unit can cool and heat a room to a certain degree, depending on the specified capacity.
#4 - Quiet and Easy Operation
A good split system operates quietly, ensuring minimal disruption, which is especially important for bedrooms or quiet areas of a home or office. The outdoor units usually produce more noise than the indoor units.
for ease of use and maintenance, choose split-system air conditioners that have filters that are easily accessible for cleaning or replacement. The exterior unit should also be designed in a way that allows for straightforward maintenance and cleaning. Some units have auto-clean and self-diagnostic features that aid the maintenance and care of the split-system units.
Modern air conditioning units also include Wi-Fi connectivity and mobile apps, allowing you to control the appliance remotely via smartphones and voice commands. You'll find programmable timers, sleep modes, and other advanced settings that enhance your experience.
#5 - Advanced Filtration and Climate Adaptability
Split system air conditioners with multi-stage air filtration can remove dust, allergens, and other pollutants, providing cleaner and healthier air. Different manufacturers have various filter technologies that ensure the air in your space is not just cool but clean.
Depending on the region, some have features like dehumidifiers (for humid climates) or frost control (for colder climates). Many modern air conditioners are more environmentally friendly and use refrigerants with lower global warming potential. The R32 refrigerant is now the common eco-friendly choice in modern split-system air conditioners in Australia.
#6 - Warranty and Support
A good warranty indicates the manufacturer's confidence in the product. Thus, we recommend choosing an appliance with a generous warranty that fits your features and budget needs.
Likewise, easy access to customer support and service can be invaluable in case of any issues. As with any appliance, good customer support can help you easily overcome the entry barrier learning curve to ensure you use the unit effectively and efficiently.
