7.2 kWActronAir Serene 7.2kW Split System
The 7.2kW ActronAir Serene Split (model WRE-072DS) is sized for large living rooms and open-plan areas. As a guide, it cools a room of up to about 52 to 60 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 or sun-exposed, step up to the 8kW.
Part of the ActronAir Serene Split range, ActronAir's split system line, in 6 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 7.2 kW options, see every 7kW split system ranked by running cost, or ask about supply and installation.
About $504 a year at the current Sydney median electricity rate: $176 of cooling plus $328 of heating, from the official GEMS test figures.
The ActronAir Serene 7.2kW uses 531 kWh per year for cooling and 989 kWh per year for heating under official test conditions in Sydney's climate zone. These figures are registered with the Greenhouse and Energy Minimum Standards (GEMS) scheme and reflect typical residential use patterns. Your actual energy consumption may vary depending on usage habits, thermostat settings and local weather conditions.
The system achieves a 4-star energy rating for cooling and 3-star rating for heating under Sydney conditions. Its rated cooling efficiency (AEER) is 3.61 and heating efficiency (ACOP) is 3.94. The ActronAir Serene uses R32 refrigerant. Running costs are calculated by multiplying your annual energy use by your local electricity rate.
