Performance and range of use

Each indoor unit is rated at 2.0 kW cooling and 3.2 kW heating capacity, while the CU-3Z75ABEC outdoor unit provides 7.5 kW cooling and 8.6 kW heating capacity; the page does not state the operating ranges. All three indoor units can cool at full capacity at the same time: their combined 6.0 kW capacity is 1.5 kW below the 7.5 kW cooling capacity of the CU-3Z75ABEC outdoor unit. In heating mode, the 9.6 kW capacity of the indoor units exceeds the 8.6 kW capacity of the outdoor unit. SEER 8.00, SCOP 4.60 according to the table; energy efficiency class A++ for cooling and A++ for heating on the A+++ to D scale. According to the page, the operating range is minus 10 to plus 46 °C for cooling and minus 25 to plus 24 °C for heating; single-phase power supply, 220 to 240 V, 50 Hz.

Room height, insulation, window area, shading and usage determine whether three rooms of this size are suitable for the set; we can check this upon request.

* Guideline based on the cooling capacity specified by the manufacturer, assuming a standard room height of approximately 2.5 m, normal insulation standards and average solar radiation. Different conditions on site, such as large window areas, sloped roofs or a high number of occupants, may require a different performance class. The definitive design is based on the specific property. For a professional design of your property, please contact us.
