3.5 kWSamsung AI Smart AIRISE WindFree 3.5kW Split System
The 3.5kW Samsung AI Smart AIRISE WindFree is sized for large bedrooms and smaller living rooms. As a guide, it cools a room of up to about 25 to 29 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 5kW.
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 3.5 kW options, see every 3.5kW split system ranked by running cost, or ask about supply and installation.
About $255 a year at the current Sydney median electricity rate: $84 of cooling plus $171 of heating, from the official GEMS test figures.
The Samsung AI Smart AIRISE WindFree 3.5kW uses 254 kWh per year for cooling and 515 kWh per year for heating, based on official GEMS test data for Sydney's climate zone. Cooling efficiency is rated 4 stars with an AEER of 3.78, while heating efficiency is rated 2.5 stars with an ACOP of 3.79. The system uses R32 refrigerant.
Your running costs depend on how much you run the unit and your local electricity rate. The energy figures above are standard test values that allow direct comparison with other models under the same test conditions.
