While searching for an air conditioning (AC) unit in countries like Singapore or Malaysia, you may encounter terms such as System 1, System 2, or System 3. These terms can be quite surprising if you don’t have any prior knowledge about them. For medium-sized households, System 3 aircon is a suitable option. But what is a System 3 aircon, and does it meet your requirements? Let’s find out.
What System 3 Aircon Mean
A System 3 aircon is a type of air conditioning system that has one outdoor condenser unit connected to three indoor units. Usually, each indoor unit is placed within a different room which have the ability for independent temperature control. This kind of arrangement is also known as multi-split air conditioning. System 3 aircons are most suitable for homes with three bedrooms or three spaces that require air conditioning.
To summarize:
- System 1 = 1 outdoor + 1 indoor
- System 2 = 1 outdoor + 2 indoor
- System 3 = 1 outdoor + 3 indoor
How Does System 3 Aircon Work?
In system 3 aircon, the single condenser is positioned outside. It is the functioning unit that draw the room temperature in the outside environment. With a System 3 configuration, this single outdoor unit is capable of handling the load for three different indoors. These indoor units may be positioned on the wall, on the ceiling, or even concealed within ducts, subject to the design of the house.
The system enables you to switch on only those areas that require cooling. It helps to save energy. Each indoor unit is usually equipped with a remote control, enabling users in every room to set the preferred temperature at their convenience.
Benefits of System 3 Aircon
Here are some benefits why a System 3 aircon:
1. Efficient Use of Space
You can save space outside the house because it needs only a single outdoor unit. This is particularly beneficial for apartments or HDB flats where space is constrained for the outdoor unit.
2. Independent Cooling for Each Room
Every indoor unit is controlled separately allowing the user to cool only the occupied rooms. This offers greater convenience and control on energy consumption.
3. Saving on Energy
The Modern System 3 aircon units feature inverter technology. These systems are energy efficient and lower electric costs over time by modifying power use depending on the room temperature and the system’s usage.
4. Aesthetic Appeal
With only one outdoor unit, the appearance of your home or building can be neatly maintained.
5. Low Noise Levels
The noise level on system 3 aircon is lower. Since the compressor and most of the noisy parts of the aircon are kept outside and the indoor units are relatively quiet, it creates less noise. In addition, many systems offer a “quiet mode” for further quiet operation.
Factors to consider before Installation
Although having System 3 aircons has many advantages, there are certain factors that you must consider:
1. The Adequate Cooling Capacity
Check if the outdoor unit’s capacity (BTU/h) is sufficient to properly serve all three indoor units. If it is not powerful, cooling efficiency may be hindered, particularly when all three units are operated simultaneously.
2. The Cost of Installation
Due to the complicated setup, the initial expense may be higher than a System 1 or System 2 aircon. Nonetheless, it is often more economically beneficial in comparison to purchasing several standalone units.
3. Maintenance
No matter how many indoor units there are, the single outdoor unit still needs at least one separate maintenance service. Look for service providers who offer comprehensive multi-split system servicing.
4. Position of Outdoor Unit
The space between the outdoor condenser unit and each indoor unit is important. If the piping runs are too long or complex, it may affect cooling efficiency or increase installation costs.
Is System 3 Aircon Suitable for You?
A System 3 aircon is appropriate for:
- 3 bedroom apartments.
- HDB flats with 3 rooms that require air conditioning.
- Home, offices or small workplaces.
- Houses that are open or have layouts with some areas divided by walls.
If you want to cool three rooms simultaneously while saving space and electricity, a System 3 is likely the most practical and economical solution.
Popular Brands For System 3 Aircons
There are several brands that are popular for system 3 aircons with modern features and facilities such as Wi-Fi control, energy-saving modes, and air purification systems. Some of the brands include:
- Mitsubishi Electric
- Panasonic
- LG
- Midea
- & more
When opting for any of the brands, remember to look for the energy rating, after sales support, noise, and maintenance facilities.
Bottom Line
A System 3 aircon offers a balance between efficiency, comfort, and space saving. This is best suited for medium-sized households looking for a dependable cooling appliance. Prior to purchasing, check with a certified aircon installer to confirm that your home’s layout and electrical configurations will accommodate a System 3 configuration.
FAQ On System 3 Aircon
What does “System 3” mean in air conditioning?
“System 3” refers to the configuration where a single outdoor condenser unit is linked to three indoor air conditioning units. It is a multi-split system that enables three rooms to be cooled separately with one outdoor unit.
Is a System 3 aircon suitable for a 4-room flat?
Yes, if three rooms, such as bedrooms and study rooms, need to be cooled independently, then a system 3 can be installed. If all four rooms require cooling, then a System 4 might be a better option.
Is it possible to operate one indoor unit only in a System 3 configuration?
Of course. Every indoor unit functions separately. Thus, you may operate all, some, or just a single unit based on your preference.
Does system 3 aircon use electricity more than other systems?
Not really. Thanks to inverter technology, it regulates the cooling load of system 3 aircon proportionate to the demand.
How frequently should I maintain a System 3 air conditioning system?
Scheduled servicing of each indoor unit should be done within a 3 to 6 month window. The outdoor condenser unit should be checked at a minimum of once per year.
