5 kWDaikin Zena 5kW Split System
The 5kW Daikin Zena Split System 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. It sits in the upper half of the Daikin Zena Split System range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 6kW.
Part of the Daikin Zena Split System range, Daikin's split system line, in 4 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 $397 a year at the current Sydney median electricity rate: $144 of cooling plus $253 of heating, from the official GEMS test figures.
The Daikin Zena 5kW uses 434 kWh per year for cooling and 765 kWh per year for heating under official GEMS testing conditions for Sydney's climate zone. These figures reflect typical annual energy consumption and form the basis of running cost estimates. The system carries a 3-star cooling efficiency rating and 2.5-star heating rating under the zoned energy labelling scheme for Sydney.
Efficiency is measured by the rated AEER of 3.77 for cooling and ACOP of 4.01 for heating. The Daikin Zena 5kW uses R32 refrigerant. Your actual running costs will depend on local electricity rates and how often you operate the system.
