Overview and comparison of air conditioners MDV: channel, inverter, mobile and cassette systems

Having appeared on the market relatively recently, but having already managed to gain good popularity, the MDV (MDV) trademark offers a wide range of climatic equipment. For a large segment of users, the most interesting are cassette and classic wall split systems. And due to the combination of price and offered characteristics, the owners of shops and offices enjoy a good reputation MDV channel systems.

A little bit about the company

Air conditioners of the MDV brand are climate systems that are manufactured by the Chinese company Midea. Despite the country of origin and some concerns of Russian consumers, it is worth noting that this is a really serious company, valuing its reputation and having the quality of its products confirmed worldwide.

To make it clear what are climate systems and cassette, duct and floor air conditioners MDV, it is worth noting: the company owns a 20% stake in the corporation Toshiba, uses their technology in their compressors, and solutions from MDV are installed in systems of other manufacturers as reliable and efficient. MDV air conditioning units, in addition to parts of their own production (80% of them), use spare parts from leading brands: Danfoss, Copeland, Sanyo. Air conditioners and channel, cassette MDV systems are in demand all over the world.

MDV production facilities are located around the world, including in Belarus, Egypt, and Brazil. It works here, producing high-quality spare parts and classic, cassette, duct climate systems of 150 thousand people. The research base is provided by 3 thousand scientists, and products from MDV are based on the application of 370 proprietary technological patents for climate equipment systems and parts of their engineering solutions described in the certificates.

Cassette Air Conditioners

Belonging to the class of semi-industrial systems, MDV cassette air conditioners provide for installation in a suspended ceiling. To do this, they have specially made cassette units of the ceiling type, the sizes corresponding to the standard panel - 60x60 centimeters. According to reviews, all models of the line are easy to install and do not create problems when designing a suspended ceiling.

However, cassette air conditioners in their characteristics are very attractive to ordinary consumers. They are quite light, as customer reviews show, they are perfectly installed in the drywall system of drywall, they make very little noise and are simply ideal for large rooms in modern apartments. There are reviews that the direction of air from the ceiling is several times more effective in maintaining the climate in the room than the flow from classic, wall split systems. The manufacturer's instructions do not limit the installation in any way, so MDV cassette air conditioners are increasingly appearing in apartments.

The advantages that cassette MDV conditioners possess include:

• fully modular construction scheme, when both cassette and console modules can be connected to an external module, which is very convenient for building air conditioning in an apartment;
• compact dimensions - only 260 mm in height and 570 mm on each side;
• excellent performance;
• There are no hard installation instructions;
• low noise, about 40 dB in different modes.
• The interesting features that cassette air conditioners MDV have include:
• separate dehumidification mode, which works without lowering the air temperature;
• the ability to equip the device with an additional wired remote control for the MDV air conditioner;
• automatic control of parameters and restart in case of failures;
• a special sleep mode, the instructions for use of which state that it not only reduces noise, but also works in a special temporary rhythm to maintain air temperature.

Duct air conditioners MDV

Channel air conditioning (multizone system) is designed to provide the desired climate inside a large office of several rooms. Mounted over a suspended ceiling, the channel block is hidden from view, and air is distributed through air ducts drawn to the desired points. Devices of this class have high performance.

If we talk about products from MDV, customer reviews indicate that ducted air conditioners can maintain the climate inside a small house. They are quiet, operating instructions guarantee excellent working conditions inside the house. Also, the presence of both cooling and heating modes make ducted air conditioners MDV an excellent solution for private housing.

The undoubted advantages of ducted air conditioners include low noise, as well as small dimensions (only 210 mm in height), which improves the conditions of use and placement inside the apartment. In addition, the operating instructions for the device declare a sufficiently large freedom for users - the air conditioner does not require special installation or maintenance.

The list of features that channel air conditioners MDV have is as follows:

• no guidance on special installation conditions;
• when turned on, the system smoothly increases the speed of the turbines depending on the change in temperature of the coolers, which leads to a smooth exit of cool air without causing any unpleasant sensations to people in the room;
• low noise level;
• automatic restart and control;
• separate special night mode.

According to reviews, the reliability of MDV equipment is fully consistent with the specifications declared by the manufacturer, the air conditioners are quiet, efficient, there are operating and installation instructions.

Mobile and wall split systems MDV

Despite the fact that the company is most widely used on the market for industrial air conditioners MDV, they also produce household inverter models: mobile and wall-mounted systems. The differences between the models are quite diverse, therefore it would be more correct to compare their technical characteristics and additional functionality in the table.

Error codes for air conditioners MDV

As you know, eternal things do not happen and a situation may arise when the MDV air conditioner simply does not turn on.Before you grieve over the expensive repairs, you should call the wizard or independently determine the nature of the malfunction, using the error codes given in the electrical diagram or instructions for the device.

Most faults and errors are identified by the internal control system of the device, and the corresponding codes, separate for the indoor and outdoor units, are displayed using LEDs on the panels and control boards. The LED can light up, blink, and a specific combination shows the nature of the error. These may be prerequisites for cleaning, adjusting, or even repairing the device when it does not respond to control programs at all.

Warning lights 4. This is Run, Timer, Defrost, Alarm. The Run lamp, when blinking, most often indicates the failure of various sensors. By the number and frequency with which the indicator flashes, error codes are determined. As an example, we can cite a group of errors: E2 - E4 - “Run blinks” - a malfunction of the room temperature sensor, evaporator control sensor, errors in determining the temperature of the output stream. Also, when the Run lamp flashes - this may mean a failure of the internal memory or an error E7 reading data from it.

The Timer LED displays communication error codes. For example, when it blinks with a frequency of 5 Hz - this means communication errors between the external and internal unit. They may even just run out of batteries.

Sometimes block error codes directly indicate a malfunction of the associated equipment. For example, when the Alarm indicator flashes slowly on the indoor unit, this means that the air conditioner does not turn on due to a malfunction of the external unit. Conversely, a similar burning LED in the outside is an error code indicating problems with the indoor unit. You may even have to change some parts.

Detailed error codes for each model are given in the user manual. Also there is information on how to independently eliminate some malfunctions and problems. A complete list of codes can be found in the reference materials for Midea air conditioners - most combinations of LED signals are the same as MDV products.
