5 kWSamsung AI Smart AIRISE WindFree 5kW Split System
The 5kW Samsung AI Smart AIRISE WindFree is sized for living rooms and master suites. As a guide, it cools a room of up to about 36 to 43 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 6.8kW.
Part of the Samsung AI Smart AIRISE WindFree range, Samsung'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 5 kW options, see every 5kW split system ranked by running cost, or ask about supply and installation.
About $418 a year at the current Sydney median electricity rate: $138 of cooling plus $280 of heating, from the official GEMS test figures.
The Samsung AI Smart AIRISE WindFree 5kW uses 418 kWh per year for cooling and 845 kWh per year for heating, based on official GEMS test data for Sydney's climate zone. The cooling function carries a 3.5-star energy rating with an AEER of 3.58, while heating is rated at 2 stars with an ACOP of 3.52. The system uses R32 refrigerant.
Your running cost depends on Sydney's current electricity rate applied to these energy figures. The star ratings and efficiency coefficients shown here are standardised test values and reflect how the unit performs under controlled conditions in Sydney's climate zone.
