9.5 kWMHI Bronte 9.5kW Split System
The 9.5kW MHI Bronte Split (model DXK33ZRA-W) is sized for very large open-plan rooms and light commercial spaces. As a guide, it cools a room of up to about 68 to 78 m². That is from Mitsubishi Heavy Industries' sizing chart for an insulated room: the larger figure if it faces north, the smaller if it faces east. Western sun, poor insulation and high ceilings bring it down. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 10kW.
Part of the MHI Bronte WF1 Split range, Mitsubishi Heavy Industries's split system line, in 5 sizes. Running costs below use the Sydney median rate; the Eastern Suburbs and Western Sydney pages cost systems on their own network tariffs. Check the size against your rooms, compare it with other 9.5 kW options, or ask about supply and installation.
About $680 a year at the current Sydney median electricity rate: $256 of cooling plus $424 of heating, from the official GEMS test figures.
The MHI Bronte 9.5kW uses 773 kWh annually for cooling and 1281 kWh annually for heating under standard government test conditions for Sydney's climate zone. These figures are registered with GEMS and reflect the system's performance in the zoned energy label test. The cooling mode carries a 3.5 star rating with an AEER of 3.69, while heating mode is rated at 2.5 stars with an ACOP of 3.88.
The system uses R32 refrigerant. Your actual running costs will depend on how often you operate the unit and your local electricity rate. The official test figures provide a consistent basis for comparing energy consumption across different models and sizes.
