Fujitsu General has launched its new two-model R32 Multi 5 Rooms Systems air-conditioning solution.
They provide heating and cooling capacity across 10kW and 12.5kW models, supporting 19 indoor unit models across six types, including wall-mounted, slimline duct, mini duct, bulkhead, ceiling and compact cassette.
It connects up to five indoor units to a single compact outdoor unit, supporting both individual comfort and centralised control, and is ideal for spaces where ducted systems aren’t practical.
The systems accommodate diverse room sizes and layouts, and are suitable for multi-storey homes, renovations and dwellings with architectural constraints across both new builds and retrofit projects.
The company says the latest addition expands its residential multi-room range with an efficient, low-environmental impact solution.
The R32 Multi 5 Rooms Systems are compatible with Fujitsu’s anywAiR wi-fi adaptor II, allowing users to monitor and adjust comfort settings remotely via a smartphone or smart speaker. Users can remotely switch units on or off, fine-tune temperature settings and adjust airflow.
The R32 Multi 5 Rooms Systems operate using R32 refrigerant, which Fujitsu claims has a 67 percent lower global warming potential than the commonly used R410A refrigerant.
It achieves an Energy Efficiency Ratio (EER) of 4.10 and a Coefficient of Performance (COP) of 4.86 for the 36-class model. Apart from the Multi 5 Rooms, the Multi 3 Rooms and Multi 4 Rooms Systems also use R32 refrigerant.
Starting in July this year, Australia banned multi-head split systems (including VRF/variable refrigerant flow systems) using refrigerants with GWP > 750 and a refrigerant charge of 2.6 kg or less. Since R32 has a GWP of 675, it is below the banned threshold, making it compliant with the new regulations.
Fujitsu General Australia and New Zealand’s general manager of product and strategy, Kyle Rafter, says the latest systems are well-suited for townhouses, units and properties with limited ceiling space or where ducted systems aren’t viable.
Engineered for Australia’s climate, the systems are capable of operating in cooling conditions up to 50°C.
“The new systems are a practical response to how people use and manage air conditioning in their homes, giving customers control, efficiency and flexibility in a single package,” Rafter says.
