In 2021, the domestic multi-connection market once again entered an upward channel. According to aiken statistics, the overall market capacity of the multi-line group in the first half of 2021 reached about 30 billion yuan, an increase of more than 45.0% over last year. Even compared with the first half of 2019 before the epidemic, the multi-connection market increased by more than 30%. According to the data of Industry Online, Midea's building technology has shipped more than 5 billion yuan in the most connected market, ranking second in the most connected market, and its growth rate is the fastest among all enterprises.
After changing its name to "Midea Building Technology", Most of the products have become one of the most important products of Midea Building Technology. In January 2022, Midea will soon launch a new multi-connection product of the V8 series. At that time, this product, which Midea Building Technology calls a new generation of multi-connection products, will unveil its mystery. So, what are its breakthrough technological innovations? Before the official release of Midea's V8 multi-line, Aiken network specially interviewed Luo Bin, general manager of Midea's building technology fluorine machine product company, so that everyone could see the black technology of Midea's V8 multi-line in advance.
Break the boundless quality, challenges never downtime
Luo Bin said that the first goal proposed by mid-term V8 multi-line is to break the boundless quality and create a three-in-one quality assurance. This trinity of quality assurance is a quality guarantee for the whole value chain, including environmental quality, installation quality and operation quality. The value of Midea's building technology to customers is not to bring unnecessary losses to customers because of abnormal failure of the machine. Therefore, the Midea V8 multi-line is supported by a number of black technologies, and the goal to challenge is to never go down!
Midea V8 multi-line takes the lead in applying some black technology from a technical point of view to ensure the quality of the environment. As we all know, the heat dissipation of the electronic control box is the stubborn disease of the current multi-line system, in order to dissipate heat to the frequency converter, the electric control box of all manufacturers is with a heat dissipation hole, which will produce many problems, such as dust, crawlers, corrosion and so on. Midea's V8 multi-line has launched the industry's first closed electric control box for this purpose.
In terms of heat dissipation of the closed electric control box, midea's V8 multi-line adopts an innovative pure refrigerant microchannel heat sink to dissipate heat from the closed electric control box. This technology is also the world's first independent research and development of Midea Building Technology.
In terms of on-site installation quality, Midea's V8 multi-connection solves the three major problems of multi-line on-site installation. Prior to this, there was only one wiring method between the multi-line internal machine and the internal machine, and Midea Building Technology and a company developed a multi-connection chip, relying on this chip to achieve multi-connection in the wiring without the need to connect the shielding wire, arbitrary connection, reducing the difficulty of on-site installation and construction. Luo Bin said that the Midea V8 multi-connection can realize a variety of connection methods such as cardioid connection, triangular connection, ring connection, etc., making it difficult for you to connect to the wrong one, and completely solve the problems in multi-connection installation.
In terms of communication stability assurance, Midea's V8 multi-connection has also made a technological breakthrough. In normal building construction, it is required that the strong and weak electricity must be separated, but if the on-site personnel are not well protected, the strong and weak electricity may be interfered with if they are close, so in the market where the multi-line installation was often installed, there was often a lack of internal machines, and the communication was suddenly not good. The Midea V8 multi-connection relies on the newly developed chip technology to achieve strong and weak power without separation, which is also a black technology of the Midea V8 multi-connection.
In addition, the Midea V8 multi-connection can also achieve the internal unit independent power supply, before that, the multi-connection is required to be unified power supply of the internal machine. Luo Bin explained that the core reason is that the new chip technology can realize the carrier on the communication line, so when an internal machine is powered down, the entire machine will not be down. This is also a technology pioneered in China.
In terms of running quality, Midea's V8 multi-line has a refrigerant amount detection system, that is, after the multi-connection is in the cloud, the amount of refrigerant in the entire system is diagnosed in real time through artificial intelligence algorithms. In the case of any sensor failure of the multi-connection, mid-line V8 multi-connection can use virtual sensor technology to achieve the entire system without downtime. At the same time, the system will also alarm in the background, waiting for after-sales personnel to come to the door for maintenance without stopping.
Break the boundaries of design and let designers become designers of beautiful buildings
The second goal of mid-term V8 multi-line is to break the boundaries of design. Luo Bin told Aiken.com: "Our purpose as a V8 multi-online developer is very pure, that is, to let Party A customers spend time on a good life, so that every designer can become the designer of a beautiful building." ”
As the external machine of most of the joint products, it is generally designed as a top air outlet, and there is a side air outlet series in the external machine of the Midea V8 multi-line. It can be placed on the same floor of the building equipment, the elevator is also very convenient, and because it is a side air outlet, there is no need to increase the wind shroud like the top air outlet series, and the footprint is very small, saving more area for Party A customers and creating more value.
For the design of indoor space, Midea's V8 multi-line also provides a variety of internal machine series. For example, there is a medium static pressure indoor unit, which can be hoisted, can also be attached to the wall, and can also be dressed upright, which allows the designer to design the space very well. Moreover, this static pressure is adaptive, and can be used through an algorithm of the motor, and no manual debugging is required after the indoor unit is installed on the site. There is also a ceiling machine with four sides, with its own high static pressure mode, even in the indoor space of four or five meters high, it can still blow the wind down.
For some small apartments and small spaces, midea V8 multi-line also has a wall-mounted internal machine that can break the boundary of the floor height, it can be mounted to the top, to achieve the front return air, so that the designer can better design the interior space.
Luo Bin said that multi-line can be born in the era of water machine prevalence, there are its unique advantages, the core value of multi-connection is that it can carry out regional management, independently switch on and off indoor units and set different temperatures and wind speeds, which is the strongest vitality of multi-line.
However, if you look at the regional control of multi-line products from the perspective of God, it does not achieve the extreme. At present, the multi-line internal machine on the market is uniformly powered, in other words, it has a control problem. Midea's V8 multi-connection takes the lead in realizing the partitioned power supply for the internal machine, breaking the boundary of energy management and enabling the multi-connection to play a greater role in the era of carbon neutrality.
Break the boundless energy saving and realize low-carbon management of the whole life cycle
The third thing to break the Midea V8 multi-line is the low-carbon unbounded, which includes several aspects.
First of all, Midea's V8 multi-connection took the lead in realizing the full DC of internal and external units in the industry. Through the dcization of the internal and external units and the unique load prediction technology of Midea Building Technology - MPC algorithm, it is another black technology, in short, it can predict the characteristics of the building, and then give the user the best wind speed and temperature and so on. Luo Bin told Aiken that the coordinated control of internal and external machines through the MPC algorithm can save 20% to 30% of energy in actual operation.
Secondly, Midea's V8 multi-line adopts the most comprehensive sensor in the industry, and its products have as many as nineteen sensors. These sensors can diagnose the system in real time for attenuation. Usually, in the case of dirty filter or dirty heat exchanger, less refrigerant, etc., the energy efficiency of the unit is slowly decreasing, but it does not affect the operation of the unit and does not report failure.
Midea's V8 multi-line nineteen sensors can calculate whether the entire system is attenuated in real time, and determine which components cause the system to attenuate. Through the big data platform and artificial intelligence algorithm, Midea's V8 multi-connection can carry out low-carbon operation and maintenance and management for Party A's customers throughout the life cycle.
Luo Bin said that this era is the era of multi-connection homogenization, and after the launch of multi-connection products, everyone is taking a route to follow. The reason why Midea's V8 multi-connection is called the new generation of multi-connection is because it can break the boundaries of quality, break the boundaries of design, break the boundaries of management, and create more value in the carbon neutral era.
Luo Bin believes that how Midea Building Technology surpasses other brands in the multi-connection industry in the future, quality and innovation are the core. Midea hopes to release a value from God's perspective to solve the problems of the multi-connection industry, and Midea's building technology should return to its original intention, starting from zero, redefining the multi-connection product, in order to finally stand at the highest point of this market.
