Description

To climate control 3 rooms with a single outdoor unit. This 3x1 Mitsubishi Electric combines 3 × MSZ-HR25VFK and has a nominal cooling capacity of 4,300 frigories/h (5 kW) for the entire system, shared when operating simultaneously. It includes indoor units of the same model: an option to compare for rooms with similar needs. Installation not included.

The capacity of the system is shared when multiple units operate simultaneously. Therefore, it is advisable to choose the combination based on the simultaneous use of the rooms, their size and orientation, as well as the layout of the pipes.

Load calculation and documentation

Outdoor unit: MXZ-3HA50VF. Check PCB and inspection.

Additional load: 20 × (Total length − 40) g, only if the sum of branches exceeds 40 m; do not exceed 50 m total or 25 m per interior.

L is the sum of the outbound runs of all branches. Do not add the liquid and gas pipes separately. Connection diameters of the exterior, in liquid / gas order. Confirm the piping and adapters of each interior.

Data to prepare the installation, not an instruction for recharging due to a fault. The charge must be verified and carried out by a qualified installer according to the PCB, the inspection, and the equipment manual; do not add refrigerant solely due to a lack of cooling.

Frequently asked questions

Questions about MXZ-3HA50VF + 3 × MSZ-HR25VFK

How many frigories does this 3x1 air conditioning unit have?

It has a nominal capacity of 4,300 frigories/h (5 kW) for the entire unit. It is not 4,300 frigories for each room nor the free sum of the powers of the splits. The available capacity is distributed among the indoor units that are operating; it changes with demand and usage conditions.

Is it suitable for 3 rooms with a single outdoor unit?

Yes: the set includes 3 × MSZ-HR25VFK and one outdoor unit. There are 3 indoor air conditioning points. To determine if it covers the specific rooms, it is necessary to check the load of each one and the simultaneous demand against the 5 kW nominal of the set; counting rooms is not enough.

Does it fit if the living room needs to be cooler than the bedrooms?

This set includes splits of the same model. If one room heats up much more than the others, it is advisable to check if it needs a different split. Tell us the square meters of each room, where the sun hits the most, and which ones you will use at the same time. With that information, we can guide you on the combination, without assuming that the living room always requires more power.

Can I add the cooling capacities of the splits to choose it?

No. In Mitsubishi Electric MXZ-3HA50VF + 3 × MSZ-HR25VFK, the reference for the published shared capacity is 4,300 frigories/h (5 kW) nominal for the set. The class figure or the indoor model number does not directly correspond to the delivered frigories. Without the distribution table for the combination, an independent figure per room is not guaranteed.

What does MXZ-3HA50VF + 3 × MSZ-HR25VFK include?

1 × MXZ-3HA50VF (outdoor unit); 3 × MSZ-HR25VFK (wall-mounted indoor units); 3 × RH18A (remote controls). The previous composition identifies the units and controls of this offer. The installation is contracted separately.

Is Wi-Fi included or is an accessory required?

Integrated Wi-Fi in each indoor unit, with control via MELCloud. No additional adapter purchase is required. The remote control operates via infrared; the Wi-Fi is built into the unit.

What command does the equipment receive?

Include 3 remote controls, one for each indoor unit: 3 × RH18A.

Can I heat just one room?

You can operate each of the 3 indoor units of this HR 25+25+25 with its remote control, without having to keep all of them on. They share the outdoor unit MXZ-3HA50VF: they can work in cooling or heating mode, but cannot cool one room while another is heating. The available capacity depends on which units are operating.

What is the distance from the rooms where I can place the MXZ-3HA50VF?

For the exterior MXZ-3HA50VF of this set, the manual allows for up to 25 m of run indoors and 50 m when adding all branches. The maximum height differences are 15 m between outdoor and indoor units and 10 m between indoor units. The actual length of the piping is measured, not the straight-line distance. The installer must check the diameters, adapters, bends, load, and equipment inspection: these limits are not installation meters included in the price.
