Performance and range of application

For the Mitsubishi Electric MXZ-2F42VF outdoor unit, cooling capacity of 4.2 kW and heating capacity of 4.5 kW are stated, adjustable from 1.1 to 4.4 kW and 1.0 to 4.8 kW, respectively. Each of the two MSZ-AY25VGK indoor units has a cooling capacity of 2.5 kW and a heating capacity of 3.2 kW. The total capacity of the indoor units is 5.0 kW, which is 0.8 kW above the capacity of the outdoor unit. Cooling operation is stated for outdoor temperatures from minus 10 to plus 46 °C, and heating operation from minus 15 to plus 24 °C. The pipe connections are stated as two 6 mm and two 10 mm.

The stated area of approximately 19 to 25 m²^* applies per indoor unit and is a guideline for standard room height and normal insulation standards, not a binding design. Room height, insulation standards, window areas, shading, and the number of people and devices are decisive. We will check the appropriate design for your property upon request.

* Guideline based on the cooling capacity stated by the manufacturer, at 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 people, may require a different performance class. The binding design is carried out on a property-specific basis. For a professional design of your property, please contact us.

How do two indoor units work with one outdoor unit?

Two separate refrigerant circuits, one per indoor unit, connected to a common outdoor unit with two connections. Each room has its own remote control and its own setpoint temperature; both can also be controlled remotely via the app.

Is the outdoor unit sufficient for both indoor units at the same time?

The two indoor units together are stated as 5.0 kW, the outdoor unit as 4.2 kW; the difference is 0.8 kW. If both rooms run at full load at the same time, each indoor unit gets about four-fifths of its rated capacity; if one runs alone, it has the full 4.2 kW. The outdoor unit regulates steplessly from 1.1 kW upwards, so it does not cycle at low load. Two rooms used simultaneously are possible with this set without restriction.

What rooms is this set suitable for?

According to the manufacturer, each indoor unit is designed for approximately 19 to 25 m²^*. Two identical indoor units fit two similarly sized rooms, and with 18 dB(A) on the lowest setting, this indoor unit is intended for bedrooms: bedroom and children's room, bedroom and study, two hotel rooms. We will carry out the binding design on a property-specific basis.

How many indoor units are included in the delivery scope?

Two MSZ-AY25VGK with 2.5 kW each, two remote controls, and the MXZ-2F42VF outdoor unit. Pipes, installation material, and the bracket or console for the outdoor unit are not part of the delivery.

Is an installation set required for each indoor unit?

Yes, two, and both are identical: the manufacturer states two 6 mm (1/4") on the liquid side and two 10 mm (3/8") on the gas side. Installation material is not included in this offer and is selected by the specialist company for the installation situation.

How large and how heavy are the units?

Each indoor unit measures 798 x 299 x 245 mm and weighs 10.5 kg. The outdoor unit measures 800 x 550 x 285 mm and weighs 37 kg; it can be mounted on a wall bracket, the load-bearing capacity is assessed by the specialist company on site.

How loud is the system?

For the indoor units, 18 dB(A) on the low setting and 36 dB(A) on the high setting are stated. For the outdoor unit, the manufacturer states 44 dB(A) in cooling and 50 dB(A) in heating operation. This page does not state a sound power level. In addition, there is a night mode that reduces the fan speed and power at night.

What filters does the indoor unit have?

An air purification filter with silver ion coating and an integrated V-Blocking filter are stated in each indoor unit. As an accessory, the manufacturer also states a Quad Connect Plasma filter, which is not included in the delivery scope. According to the manufacturer, the filters are cleaned regularly; this is part of the maintenance.

How far apart can the indoor and outdoor units be?

This page does not state the permissible pipe length and the permissible height difference; we will provide both values upon request. Two pipe routes are to be planned, both from the outdoor unit's location.

Can I heat with the system in winter?

Heating operation is stated for outdoor temperatures from minus 15 to plus 24 °C, cooling operation from minus 10 to plus 46 °C. In heating operation, class A++ applies on the A+++ to D scale with an SCOP of 4.60; the outdoor unit heats with 4.5 kW, each indoor unit with 3.2 kW, so each heats more than it cools. The i-save function stores a reduced setpoint temperature and recalls it at the touch of a button, for example for the night or absence. Whether the system is sufficient as the sole heating system, we will check upon request.

Can I install the air conditioner myself?

Installation and commissioning of a Multi Split air conditioner is carried out by a certified specialist company; self-installation is not intended. Two pipe routes and one 37 kg outdoor unit need to be planned.
