4.6 kWDaikin Alira X 4.6kW Split System
The 4.6kW Daikin Alira X Split System is sized for living rooms and master suites. As a guide, it cools a room of up to about 33 to 39 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 sits in the lower half of the Daikin Alira X Split System range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 5kW.
Part of the Daikin Alira X Split System range, Daikin's split system line, in 7 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 4.6 kW options, or ask about supply and installation.
About $278 a year at the current Sydney median electricity rate: $110 of cooling plus $168 of heating, from the official GEMS test figures.
The Daikin Alira X 4.6kW uses 333 kWh per year for cooling and 506 kWh per year for heating, based on official energy label test data for Sydney's climate zone. These figures show the standard energy consumption under the GEMS registration test conditions.
The system achieves a 4-star energy rating for cooling and 3.5-star rating for heating in Sydney's zone. It has a rated cooling efficiency (AEER) of 4.17 and heating efficiency (ACOP) of 4.59. The unit operates on R32 refrigerant. Your actual running costs will depend on how often and for how long you run the system.
