All types of Japanese air conditioners MITSUBISHI are divided into two categories: ELECTRIC and HEAVY INDUSTRIES. Both those and other representatives of this brand have household, semi-industrial and industrial series of various types. They are distinguished by reliable operation in any conditions from +40 to - 15 ° С, high-quality assembly of each device and equipped with convenient additional functionality.
MITSUBISHI conditioners: characteristics and features
Like all manufacturers of HVAC equipment, MITSUBISHI ELECTRIC produces many series and types of domestic and semi-industrial air conditioners, with inverter and standard compressor controls. The latter are distinguished by greater power, a more complex filtration system, an increased length of the connecting lines and the possibility of height differences between the blocks of the component system.
Split systems
Splits have several standard series - these are wall, cassette, channel, mobile and other models that consist of a pair of modules - indoor and outdoor. All of them can be installed both in residential and in public buildings, depending on the required capacity relative to the size of the room. They can also be part of semi-industrial multi-splits.
Wall conditioners mitsubishi
Wall-mounted air conditioners of this company are capable of processing an area of 15 to 100 m². They have a number of features in terms of their technical characteristics and additional functions, namely:
- optimal ratio of power and energy consumption;
- reduced noise values - from 22 dB;
- ergonomic dimensions;
- absence of controller failures in case of network problems due to a switching power supply;
- the presence of a daily timer, automatic restart, the function of maintaining temperature, taking into account the personal sensations of a person.
MITSUBISHI ELECTRIC wall-mounted air conditioners have an attractive design - they look neatly on the wall and do not spoil the overall interior.
Channel systems
Like other climatic equipment, MITSUBISHI duct air conditioners perform standard tasks: work on cold / heat + drainage and air purification.
In addition to its recycling in the room, they can mix oxygen from the street if, when laying the system, one of the channels (ducts) was brought out. Installation is made in the area of space between the suspended structure and the ceiling.
Since channel air conditioning is a complex system in its design, it is better to install it before repair work at the facility.
The main features of MITSUBISHI canals include:
- optimal ratio of efficiency and energy consumption;
- low noise effect - from 23 dB;
- static pressure adjustment;
- great opportunities for the length of the connecting lines and the difference in height between the blocks;
- safety for the ozone layer through the use of environmentally friendly refrigerant;
- high-quality air filtration system.
At MITSUBISHI ELECTRIC all channel air conditioners can carry out zone control by setting different temperature parameters in separate rooms at the same time.
Cassette systems
If the room has a typical Euro ceiling with cells of 60 × 60 cm, MITSUBISHI cassette air conditioners with an improved air distribution system providing a comfortable microclimate are perfect.
The main feature is the lack of a service hatch. All work is carried out through an external decorative panel.
MITSUBISHI ELECTRICIAN all cassette air conditioners have:
- high power - up to 14.5 kW when working in the cold and 16.8 kW for heat;
- noise level comparable to a slight whisper during a conversation;
- many built-in modes and functions - automatic temperature maintenance, restart after malfunctions, backup system operation, the ability to change the direction of air flows in horizontal and vertical planes;
- a multi-stage air filtration system that not only captures bacteria, but also breaks them down to a harmless state;
- protection against drops in the power supply network.
The installation of the MITSUBISHI ELECTRIC cassette air conditioner is necessary where wall mounting is not possible due to the architectural or design features of the room.
Ceiling systems
The most smooth and even distribution of air masses is carried out by the floor-and-ceiling air conditioner, which directs their flows upwards, where they disperse throughout the room. This technology eliminates drafts.
The improved design of the internal module allows you to hide the device in the wall for several centimeters, which makes it less noticeable. The presence of the function of economical consumption makes it possible to reduce energy consumption during rest. Above 18 ° C the temperature will not rise. The same function can be used if it is necessary to maintain minimum heat parameters (10 ° C).
Floor and ceiling models have a number of features. And this:
- air filtration in several stages;
- lack of noise during the work;
- weekly timer;
- automatic restart;
- self-diagnosis with the error code displayed on the control panel.
Most floor and ceiling fixtures can be mounted on an old piping system.
Inverter air conditioners
MITSUBISHI ELECTRIC also produces inverter air conditioners of all the listed types. Their main difference is an even more thought-out system of reasonable energy consumption, coupled with high performance.
Some series are equipped with an electronic printing unit that measures the temperature and relative to this regulates the power of the electric heater of the compressor crankcase, which allows to reduce the consumption of electricity in the off state.
An additional silent fan mode for MITSUBISHI ELECTRIC inverter air conditioners allows reducing noise characteristics to the minimum values of 21 dB.
A filtration system with a nanoplatinum filter decomposes bacteria to safe constituents, absorbs odors and traps allergens, preventing them from entering the room.
All MITSUBISHI inverter air conditioners have many convenient modes and functions such as auto-maintenance of air temperature and heating on duty.
Multi split systems
If necessary, install one external module and several internal ones, for example, if you do not want to spoil the building’s facade with many outdoor units, a MITSUBISHI ELECTRIC multi-split system is mounted.
One external unit can connect the mitsubishi air conditioner indoor unit. It is possible to connect 8 indoor units. They differ:
- high efficiency + minimum energy consumption due to the use of a concentrated type winding in the motor stator and pulse-amplitude modulation in the power circuit;
- noise values from 21 dB;
- insensitive to temperature fluctuations from the outside thanks to the receiver-cooler;
- high-quality nanoplatinum filtration system with an increased area of the absorbing grating;
- advanced blinds system, which allows air flow to be distributed in several directions;
- a weekly timer capable of adjusting 4 actions every day.
For outdoor modules, the noise level may decrease by a few dB when you turn on night mode.
The company provides not only the free layout of the system blocks, but also ready-made kits for installation on different areas.
Mobile air conditioners
The purchase of a MITSUBISHI mobile air conditioner is justified if it is necessary to move the unit from room to room, or if it is not possible to wall-mount the device.
Any modern mobile air conditioner, including MITSUBISHI, has the characteristics and additional capabilities that do not differ much from the parameters of two-component systems. It cools the air perfectly and has built-in functions and modes that allow you to restart the device and adjust the air supply.
But it is worth remembering that a mobile air conditioner is more noisy than a split. This is due to the location of the compressor in the unit itself.
Upon purchase, the availability of the possibility of taking a corrugated hose to the street to eliminate warm air and condensate from the device is taken into account.
Industrial systems
For the processing of air masses in medium and large rooms with an area of up to several thousand meters, multi-zone installations are used, which in the way of assembly resemble a children's designer. The outdoor air conditioner of such an industrial MITSUBISHI ELECTRIC system can connect dozens of indoor ones. In this case, there can also be several external modules.
Multizone systems are controlled either from a conventional room remote control or from a virtual computer connected to a network on a monitor. At the same time, in different rooms, the specified air adjustment parameters can be completely different. In one, the work goes to heat, and in the other to heat. In this case, the CITY-MULTI 2 two-pipe system is used. It is functional at very low outdoor temperatures due to water cooling.
And the CITY MULTI VRF system is the most economical due to the variable refrigerant flow rate, i.e. is semi-industrial.
All industrial air conditioners of MITSUBISHI ELECTRIC are distinguished by an increased footage of the route and large elevation differences between the system modules + huge power values reaching several thousand kW.
Repair of air conditioners MITSUBISHI ELECTRIC
If you experience any malfunction, you should immediately call the MITSUBISHI ELECTRIC air conditioning repair service, which will conduct:
- inspection of system components and pipelines;
- checking the operation of the electrical circuit of the equipment.
Based on the diagnostic results, either troubleshooting on the spot or in the service center is carried out.
Typical problems that may require standard maintenance or repair of the MITSUBISHI ELECTRIC air conditioner are:
- lack of refrigerant;
- dirty air filters or condenser;
- blockage of the drainage system;
- depressurization of drain pipe connections;
- failure of the compressor, the starting capacitor of the fan of the external module, the 4-way valve, the fan motor of one of the blocks;
- damage to the control board, due to which the air conditioner may not turn on.
Many problems are associated with poor-quality installation of the system, ignoring the electrical circuit for connecting the MITSUBISHI air conditioner, exceeding the load on the network. Compliance with all installation rules extends the life of the device and eliminates the possibility of fires.
Sometimes it is not possible to find a wiring diagram for a specific MITSUBISHI air conditioner. In such situations, you must contact the official service center and make a request for this documentation.
Any electrical circuit for connecting the MITSUBISHI air conditioner is a schematic drawing of all components of the equipment and their connections to each other through electricity. It will be needed not only during installation, but also if necessary, repairs.
Repair of the MITSUBISHI air conditioning control board is carried out by radio electronics specialists.Chips, relays, and other components could fail. Repair occurs regardless of the design features of the device itself.
If the control board of the MITSUBISHI air conditioner is located in the outdoor module, then on-site diagnostics are needed, since in most cases the cause of the breakdown is other elements - sensors, compressor, and so on.
To avoid repair of the MITSUBISHI ELECTRIC air conditioner, regular servicing is required.

MITSUBISHI HEAVY conditioners
MITSUBISHI HEAVY (MH) is a completely different company, one of many brand affiliates. It produces climate equipment in a more economical version. Features such as noise level, power, energy efficiency are inferior to those of MITSUBISHI ELECTRIC air conditioners. The climate technology MH simplifies the design of devices and uses simpler components. At the same time, their price is significantly reduced in comparison with ME.
General characteristics of air conditioners
Despite the superiority of ME equipment, MITSUBISHI HEAVY INDUSTRIES air conditioners remain in demand in the climate technology market. There are many reasons for this:
- They correspond to energy class A with their good performance;
- These systems use a safe refrigerant with zero ozone destruction potential;
- Exit to set temperatures occurs quickly and at any speed due to the VECTOR CONTROL system;
- The system has reliable protection in the form of anti-corrosion coating of the material of the blocks and silicone coating of the board, which keeps it from moisture;
- Due to the improvement of the air supply system, the flows are distributed in 3 different directions fairly evenly. There is no zonal temperature difference for any room configuration;
- Most models of air conditioners are equipped with a scroll compressor, which consists of two spirals inserted into each other. The outer revolves around the inner. In this case, the points of contact are on each turn of the second. Due to this, the refrigerant vapor is compressed more smoothly and in smaller portions, which creates a lower load on the compressor motor;
- The filtration system consists of several stages of cleaning. It includes anti-mite (enzyme), photocatalytic deodorizing and antibacterial filters;
- Each air conditioner has numerous additional functions and modes, such as automatic temperature maintenance, humidity control, optimization of nighttime operation, shutdown and on timer, auto restart after shutdown due to network outages and so on.
MITSUBISHI HEAVY INDUSTRIES has both inverter and non-inverter air conditioners of various types. Wall splits, ducts, cassettes, floor, floor-ceiling and mobile systems are all the same type series as MITSUBISHI ELECTRIC. Models and sizes - in a wide variety.
MITSUBISHI HEAVY also produces semi-industrial multi-splits and industrial multi-zone VRV and VRF systems.
MH launched several lines of heat pumps that, in addition to air conditioning, also organize water heating and a heating system in homes and public buildings.
