We consider cassette, channel and other models of MITSUBISHI air conditioners, their repair and reviews to them

All types of Japanese MITSUBISHI air conditioners 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 equipment with convenient additional functionality.

MITSUBISHI air 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 control. The latter are distinguished by greater power, a more complex filtering system, an increased length of 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, duct, mobile and other models, which consist of a pair of modules - indoor and outdoor. All of them can be installed both in residential and public buildings, depending on the required power in relation to the size of the room. They can also be part of semi-industrial multi-splits.

Mitsubishi wall-mounted air conditioners

Wall-mounted air conditioners of this company are capable of treating an area from 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;
• no controller failures in case of network failures due to a pulsed power supply;
• the presence of a daily timer, automatic restart, the function of maintaining the temperature, taking into account the personal feelings of a person.

Wall-mounted MITSUBISHI ELECTRIC air conditioners have an attractive design - they look neat 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 + dehumidification and air purification.

In addition to recirculating it indoors, they can mix oxygen from the street if, when the system was laid, one of the channels (air ducts) was brought out. Installation is carried out in the area between the suspended structure and the ceiling.

Since the duct air conditioner is a complex system by its design, it is better to install it before repair work at the facility.

The main features of MITSUBISHI ducts include:

• optimal ratio of efficiency and energy consumption;
• low noise effect - from 23 dB;
• regulation of static pressure;
• great opportunities for the length of the connecting lines and the height difference between the blocks;
• safety for the ozone layer due to the use of an environmentally friendly refrigerant;
• high-quality air filtration system.

At MITSUBISHI ELECTRIC, all channel air conditioners can perform zone control, setting different temperature parameters in separate rooms at the same time.

Cassette systems

If there is a typical "euro" ceiling in the room 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 absence of a service hatch. All work is carried out through an external decorative panel.

At MITSUBISHI ELECTRIC, all cassette air conditioners have:

• high power - up to 14.5 kW for cold operation and 16.8 kW for heat;
• noise level comparable to a slight whisper during a conversation;
• a variety of built-in modes and functions - automatic temperature maintenance, restart after malfunctions, redundant system operation, the ability to change the direction of air flows in the horizontal and vertical planes;
• a multi-stage air filtration system that not only traps bacteria, but also breaks them down to a harmless state;
• protection against power surges.

Installation of a cassette air conditioner MITSUBISHI ELECTRIC is necessary where wall mounting is impossible due to the architectural or design features of the room.

Floor and ceiling systems

The smoothest and most even distribution of air masses is carried out by a floor-ceiling air conditioner, which directs their flows upward, where they diverge throughout the room. This technology eliminates the appearance of drafts.

The improved design of the indoor module allows the device to be hidden in the wall by a few centimeters, making it less visible. The economical consumption function makes it possible to reduce energy consumption during rest. The temperature will not rise above 18 ° C. The same function can be used if it is necessary to maintain the minimum heat parameters (10 ° C).

Floor and ceiling models have a number of other features. And this:

• air filtration in several stages;
• lack of noise during operation;
• weekly timer;
• automatic restart;
• self-diagnosis with displaying an error code on the control panel.

Most floor-to-ceiling fixtures can be installed on the old piping system.

Inverter air conditioners

MITSUBISHI ELECTRIC also manufactures inverter air conditioners of all listed types. Their main difference is an even more sophisticated system of reasonable energy consumption, coupled with high performance.

Some series are equipped with an electronic printed circuit board that measures the temperature and, in relation to this, regulates the power of the electric heater of the compressor crankcase, which allows to reduce the consumption of electricity when it is off.

The additional quiet fan mode of MITSUBISHI ELECTRIC inverter air conditioners allows to reduce the noise characteristics to a minimum value of 21 dB.

A filtration system with a nanoplatinum filter decomposes bacteria to harmless components, absorbs odors and traps allergens, preventing them from entering the room.

All MITSUBISHI inverter air conditioners have a variety of convenient modes and functions such as automatic air temperature maintenance and standby heating.

Multi-split systems

If it is necessary to install one external module and several internal ones, for example, if you do not want to spoil the facade of the building with many external blocks, the MITSUBISHI ELECTRIC multi-split system is mounted.

One outdoor unit can connect mitsubishi air conditioner indoor unit. Connection of 8 indoor units is possible. They differ:

• high efficiency + minimum energy consumption due to the use of a lumped type winding in the stator of the motor and amplitude-pulse modulation in the power circuit;
• noise values ​​from 21 dB;
• insensitivity to temperature fluctuations outside due to the receiver-subcooler;
• high-quality nanoplatinum filtration system with an increased area of ​​the absorbing grid;
• an improved louver system that allows the air jet to be distributed in several directions;
• a weekly timer capable of regulating 4 actions every day.

For outdoor units, the noise level can be reduced by several dB when the night mode is turned on.

The company provides not only free arrangement of 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 in the event that it is necessary to move the unit from room to room, or in the absence of the possibility of wall mounting the device.

Any modern mobile air conditioner, including MITSUBISHI, has 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 the mobile air conditioner is noisier than the split air conditioner. This is due to the location of the compressor in the unit itself.

When purchasing, it is taken into account that a corrugated hose can be brought out into the street to remove warm air and condensation from the device.

Industrial systems

For processing air masses in medium and large rooms with an area of ​​up to several thousand meters, multi-zone installations are used, which, by the way of assembly, resemble a children's designer. An outdoor air conditioner of such an industrial MITSUBISHI ELECTRIC system can connect dozens of indoor air conditioners. In this case, there can also be several external modules.

Multi-zone systems are controlled either from a conventional room control panel, or from a virtual computer on the monitor connected to the network. At the same time, in different rooms, the specified air regulation parameters can be completely different. In one, the work goes to heat, and in the other - to heat. In this case, a two-pipe system CITY-MULTI 2 is used. It is functional at very low outside temperatures due to water cooling.

And the VRF system CITY MULTI is the most economical due to the variable refrigerant flow rate, i.e. is semi-industrial.

All industrial air conditioners MITSUBISHI ELECTRIC differ in the increased footage of the route and large differences in height between the modules of the system + huge power values, reaching several thousand kW.

Repair of air conditioners MITSUBISHI ELECTRIC

If any malfunctions occur, you must immediately call the MITSUBISHI ELECTRIC air conditioner repair service, which will conduct:

• inspection of system components and pipelines;
• checking the operation of the electrical circuit of the equipment.

Based on the results of the diagnostics, either the troubleshooting is carried out on the spot or in the service center.

Typical problems that may require routine 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 the drainage pipeline connections;
• failure of the compressor, starting capacitor of the outdoor unit fan, 4-way valve, fan motor of one of the units;
• breakage of 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 prolongs the service life of the device and excludes the possibility of fires.

Sometimes it is impossible to find a wiring diagram for a specific MITSUBISHI air conditioner. In such situations, you must contact an official service center and make a request for this documentation.

Any electrical diagram for connecting a MITSUBISHI air conditioner is a schematic drawing of all the component parts of the equipment and their connections to each other by means of electricity. It will be needed not only during installation, but also if repair is necessary.

The repair of the control board of the MITSUBISHI air conditioner is carried out by radio electronics specialists. Chips, relays and other components could fail. The repair takes place 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 is needed, since in most cases other elements are the cause of the breakdown - sensors, a compressor, and so on.

To avoid the repair of the MITSUBISHI ELECTRIC air conditioner, it is necessary to carry out regular servicing.

Air conditioners MITSUBISHI HEAVY

MITSUBISHI HEAVY (MH) is a completely different company and is one of the many subsidiaries of the brand. It produces climatic equipment in a more economical way. Such characteristics as noise level, power, energy efficiency are inferior to those of MITSUBISHI ELECTRIC air conditioners. The MH HVAC technology has a simplified design 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 HVAC market. There are many reasons for this:

• They correspond to energy efficiency class A with good performance;
• These systems use a safe refrigerant with zero ozone depletion potential;
• The set temperature is reached quickly and at any speed due to the VECTOR CONTROL system;
• The system has reliable protection in the form of an anti-corrosion coating of the block material and a silicone coating of the board, which keeps it from moisture penetration;
• Due to the improvement of the air supply system, the streams are distributed in 3 different directions quite evenly. There is no zonal temperature difference for any room configurations;
• Most models of air conditioners are equipped with a scroll compressor, which consists of two spirals inserted into each other. The outer one revolves around the inner one. In this case, the points of contact are on each second loop. Due to this, refrigerant vapors are compressed more smoothly and in smaller portions, which creates less stress on the compressor motor;
• The filtration system consists of several stages of cleaning. It includes anti-mite (enzyme), photocatalytic deodorant and antibacterial filters;
• Each air conditioner has numerous additional functions and modes, such as automatic temperature maintenance, humidity control, optimizing nighttime operation, timer shutdown and restarting, auto-restart after disconnection due to network failures, 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 - all the same standard series as those of MITSUBISHI ELECTRIC.Models and sizes - in a wide variety.

MITSUBISHI HEAVY also manufactures semi-industrial multi-split and industrial multi-zone VRV and VRF systems.

MH has launched several lines of heat pumps, which, in addition to air conditioning, also organize water heating and heating systems in houses and public buildings.
