5 kWMitsubishi Electric MSZ-LN 5kW Split System
The 5kW Mitsubishi Electric MSZ-LN Premium Split (model MSZ-LN50VG) 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 6.1kW.
Part of the Mitsubishi Electric MSZ-LN Premium Split range, Mitsubishi Electric'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 $388 a year at the current Sydney median electricity rate: $137 of cooling plus $251 of heating, from the official GEMS test figures.
The Mitsubishi Electric MSZ-LN 5kW uses 414 kWh per year for cooling and 757 kWh per year for heating, based on official GEMS test data for Sydney's climate zone. These figures allow you to calculate running costs using your current electricity rate. The system carries a 3.5-star cooling rating and 2.5-star heating rating under the zoned energy labelling scheme for Sydney.
The Mitsubishi Electric MSZ-LN achieves a rated AEER of 3.61 for cooling and ACOP of 4.04 for heating. It uses R32 refrigerant. Your actual energy consumption will depend on your usage patterns, thermostat settings and how well your home is insulated.
