Mitsubishi Electric Multi Split Set from the MSZ-LN series in Pearl White, Onyx Black or Ruby Red: three MSZ-LN18VG2 indoor units with 1.8 kW each connected to an MXZ-3F54VF3 outdoor unit with 5.4 kW cooling and 7.0 kW heating capacity, the sum of the indoor units matches the capacity of the outdoor unit, energy efficiency class A+++ in cooling and A++ in heating on the scale from A+++ to D. SEER 8.52 and SCOP 4.61, 19 dB(A) on the lowest fan speed, 3D i-see sensor and WiFi control in each indoor unit, three smaller rooms of approximately 14 to 18 m²^* per indoor unit.

Performance and range

For the Mitsubishi Electric MXZ-3F54VF3 outdoor unit, the manufacturer states 5.4 kW cooling capacity with a control range of 2.9 to 6.8 kW and 7.0 kW heating capacity with a control range of 2.6 to 9.0 kW. The three MSZ-LN18VG2 indoor units are rated at 1.8 kW cooling capacity each, totaling 5.4 kW and thus exactly the same as the outdoor unit. The operating range is stated as minus 10 to plus 46 °C for cooling and minus 15 to plus 24 °C for heating. All three connections on the outdoor unit have 6 mm on the liquid side and 10 mm on the gas side.

Approximately 14 to 18 m²^* per indoor unit is a guideline at standard room height and normal insulation standard, not a binding design. Whether three smaller rooms are suitable for this combination depends on room height, insulation, window areas, shading and usage; we will clarify this upon request.

* Guideline based on the cooling capacity stated by the manufacturer, at a standard room height of approximately 2.5 m, normal insulation standard and average solar radiation. Different conditions on site, such as large window areas, sloped roofs or a high number of people, may require a different performance class. The binding design is carried out on an object-specific basis. For a professional design of your property please contact us.

How do three indoor units work with one outdoor unit?

Three connections on the MXZ-3F54VF3 outdoor unit with 6 and 10 mm each, three indoor units, three separate refrigerant lines. Each room regulates the temperature and fan speed independently, via remote control or app; the outdoor unit bundles the demand and provides between 2.9 and 6.8 kW.

Is the outdoor unit sufficient for all three rooms at the same time?

Yes, and fully: three indoor units with 1.8 kW each result in 5.4 kW, exactly the capacity stated for the outdoor unit. Even at full load in all three rooms at the same time, each indoor unit gets its full rated capacity; the control range of the outdoor unit extends beyond that up to 6.8 kW. The manufacturer freely allows the combination.

For which rooms is this set suitable?

According to the manufacturer, each indoor unit is suitable for approximately 14 to 18 m²^*, so for three smaller rooms: three children's rooms, bedrooms, study and guest rooms, three rooms of a guesthouse. Since the sum of the indoor units matches the capacity of the outdoor unit, all three rooms can run continuously at the same time. The 3D i-see sensor in each indoor unit detects the temperature distribution and directs the air accordingly. The binding design is carried out on an object-specific basis.

How many indoor units are included in the scope of delivery?

Three MSZ-LN18VG2 indoor units in the chosen color (V, B or R), three infrared remote controls and the MXZ-3F54VF3 outdoor unit. Refrigerant lines, mounting material and the console or bracket for the outdoor unit are not included.

What filters does the indoor unit have?

According to the manufacturer, each indoor unit has an air purification filter and a silver ion air purification filter, the same for all three colors. The filters are part of the regular maintenance and are cleaned or replaced, three times for three indoor units.

How far apart can the indoor and outdoor units be?

The permissible total line length, the length per indoor unit and the permissible height difference are not stated on this page; we will tell you these values upon request. Three lines meet at the outdoor unit, whose stand is therefore determined first.

Can I use the system for heating in winter?

Yes. The heating mode is rated for outdoor temperatures from -15 to +24 °C, and the cooling mode from -10 to +46 °C. In heating mode, it achieves an A++ rating on the A+++ to D scale with a SCOP of 4.61; the outdoor unit provides 7.0 kW of heating capacity, and we can provide the heating capacity for each indoor unit upon request. The winter kit keeps the outdoor unit ready for operation in cold weather, while the anti-freeze protection prevents the indoor unit from blowing air until the heat exchanger is warm. We can check upon request whether three rooms can be heated using this system alone.

Can I install the air conditioning system myself?

No. Installation and commissioning must be carried out by a certified specialist company. You will need to plan for three pipe routes, three condensate drains, an electrical supply line, and a space for a 58 kg outdoor unit.
