5 kWPanasonic Z Series 5kW Split System
The 5kW Panasonic Z Series (model CS-Z50AKRW) is sized for living rooms and master suites. As a guide it suits a typical insulated room of roughly 33 to 40m²; sun exposure and ceiling height move that band. Like the rest of the Z Series it runs nanoe X air purification around the clock. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 6kW.
The Panasonic Z Series 5kW uses 402 kWh per year for cooling and 813 kWh per year for heating, based on official GEMS testing in Sydney's climate zone. These figures reflect typical household use patterns and allow you to calculate running costs against your local electricity rate. The system achieves a cooling efficiency rating of 3.5 stars and a heating efficiency rating of 2.5 stars under the zoned energy labelling scheme.
Efficiency is measured by AEER (cooling) at 3.29 and ACOP (heating) at 3.47, indicating how much cooling or heating output you get per unit of energy consumed. The system uses R32 refrigerant. Your actual energy consumption will vary depending on how often you run the unit, your preferred temperature settings and local weather conditions.
