2.5 kWSamsung AI Smart AIRISE WindFree 2.5kW Split System
The 2.5kW Samsung AI Smart AIRISE WindFree is sized for standard bedrooms and small home offices. As a guide, it cools a room of up to about 18 to 21 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. It is the smallest capacity in the Samsung AI Smart AIRISE WindFree range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 3.5kW.
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 2.5 kW options, see every 2.5kW split system ranked by running cost, or ask about supply and installation.
About $182 a year at the current Sydney median electricity rate: $56 of cooling plus $126 of heating, from the official GEMS test figures.
The Samsung AI Smart AIRISE WindFree 2.5kW uses 169 kWh per year for cooling and 380 kWh per year for heating, based on official GEMS testing in Sydney's climate zone. The system carries a 4.5-star energy rating for cooling and a 3-star rating for heating under the zoned energy label. Running costs depend on your local electricity rate and how much you use the system.
Efficiency is measured by AEER (annual energy efficiency ratio) for cooling at 4.35 and ACOP (annual coefficient of performance) for heating at 4.29. The unit uses R32 refrigerant. These figures are standard test values established by government testing and will differ from your actual usage based on your home, climate conditions, and how you operate the system.
