The trade and production brand MB was engaged in the production of climatic equipment, office equipment and office equipment. Currently, the company practically does not work, the dealer network and trade representations are closed. The actual manufacturer of MB air conditioners is the Chinese plant Midea. The company made purchases of split systems and ducted air conditioners.
Main lines of air conditioners and products
The most popular MB air conditioners:
- Split system for installation in residential and commercial premises. Three models were offered with cooling capacities ranging from 2.6 to 5.3 kW. Inverters in outdoor units were not installed. The design is standard - an internal block of a classic shape with a convenient display of parameters. Features - for the most powerful model, the maximum length of the highways was 15 m. Usually this figure does not exceed 10 m.
- Channel climatic equipment. Five varieties have been developed from 5.3 to 17.6 kW. The devices work for cooling, heating and ventilation. There is a night mode with noise reduction. Features - small thickness of the indoor unit - 300 mm. This allows it to be installed in standard air ducts or in the space between decorative and draft ceilings.
Since the development of the design was carried out in the early 2000s. - wall-mounted indoor and outdoor units are designed to use outdated refrigerant r22. It is not known whether it can be replaced without deteriorating performance.
During the installation, problems arose - the connection diagram of the switching block of the outdoor and indoor unit differs from the actual data. This point must be clarified in advance with the former owner, if a used model is being bought.
Comparison of characteristics of popular models
Therefore, we suggest that you familiarize yourself with the main parameters of wall-mounted climatic equipment:
- Determine the required power. It depends on the area of the room. For a standard ceiling height of 2.75 m, the ratio applies - 1 kW of power is needed for 10 m² of area.
- The presence of heating and ventilation modes. In the first case, you need to take into account the minimum permissible value of the air temperature outside. For these models, it is -16 ° C.
- Adjustable power range. For cooling - from + 17 ° С to + 30 ° С.
- The length of the route between blocks. This is necessary to determine the installation location.
- Possibility to activate sleep or Turbo mode. In the first case, the noise level will be minimal, the second is necessary for operational cooling of the room.
- Dimensions of the outdoor and indoor unit.
The latter is necessary so that the installation of the air conditioner is carried out according to the manufacturer's recommendations. Otherwise, there will be no guarantee of normal operation.
The table shows the comparative characteristics of the company's popular wall-mounted models.
| Model | 2.6SH-R2 | 3.5SH-R2 | 5,3SH-R2 |
| Cooling / heating capacity | 2,6/2,9 | 3,5/3,8 | 5,3/5,9 |
| Power consumption | 0,96/0,98 | 1,3/1,3 | 1,92/1,98 |
| Air performance | 520 | 540 | 1160 |
| Length of traces between blocks | 10 | 10 | 15 |
| Indoor unit dimensions | 70*53,5*23,5 | 78*54*25 | 78*54*25 |
| Noise level | 23 | 28 | 31 |
| Price | 12500 | 14700 | 17800 |
The table contains the last known price for the model. The used cost is 10-15% lower, depending on the degree of wear and the actual condition of the blocks.
The advantage is a wide operating temperature range. The manufacturer guaranteed normal operation at outdoor temperatures down to -16 ° C.
Instructions for the control panel and air conditioners MB
Changing the operating parameters of the climatic equipment is possible in two ways - using the remote control and directly on the indoor unit. For the first option, a functional air conditioner control panel was developed. Features - buttons for switching modes are hidden under the pull-out panel. This is to minimize the likelihood of accidental clicking. Buttons for changing the intensity of heating or cooling are located under the LCD display.
The instruction for air conditioners contains the following information about the remote control:
- the ability to activate and deactivate the indoor unit;
- changing the heating and cooling power of the room;
- hibernation activation;
- changing the angle of the direction of the air flow due to the inclination of the blinds, it is possible to turn on the swing mode;
- off timer settings.
The LCD displays the current operating parameters. The instruction contains an explanation of the pictograms.
Basic rules of service:
- you need to clean the air filter at least once a year;
- control the amount of refrigerant;
- when the outdoor temperature drops below the critical one, the outdoor unit cannot be turned on.
It is recommended to do a due diligence before each season. For this, specialized specialists are invited who, using special equipment, check the condition of the outdoor and indoor units.
Error codes for air conditioners MB
In the event of malfunctions or breakdowns in the operation of the climatic equipment, the notification option is activated. The screen displays error codes that indicate the nature of the breakdown. This will help the technician to remotely determine the extent of the problem and prepare for repair.
The main reasons for the appearance of breakdowns:
- The appearance of a leak. This is due to the skew of the indoor unit.
- Compressor breakdown. It occurs due to loss of tightness in the lines or incorrect setting of the refrigerant pressure level in the circuits.
- Failure of temperature sensors.
- Poor air supply. The air filter was not cleaned in a timely manner.
- The indoor unit does not turn on. A common cause is a power outage or a tripped protective relay.
If these problems appear, you should consult with specialists. The best thing is to call them for a comprehensive diagnosis and repair. Attempts to self-restore performance can aggravate the situation.
User reviews
Due to the long absence of models from this manufacturer on sale, it is difficult to find objective consumer reviews. Most of the information about the work and the specifics of service relates to used equipment and is discussed by specialized specialists.
Based on this data, the following advantages can be distinguished:
- reliability of work;
- easy maintenance;
- functioning at a low temperature outside;
- the length of the lines.
The disadvantages include:
- the use of an outdated type of refrigerant;
- lack of service centers;
- remote control without temperature sensor and backlight.
The main problem is difficulties with repair and maintenance. If the company does not resume sales of these models, after a while they will disappear from the secondary market of climate control equipment.
