The crux of the problem is: how to achieve "carbon neutrality"? There is no doubt that tens of millions of enterprises of all kinds are crucial participants on the road to carbon neutrality.
Among them, the role of technology companies is particularly critical.
From the current situation, world-class technology giants such as Google, Apple and Facebook have led the trend of 100% renewable energy-at the same time, China technology enterprises have been committed to "carbon neutrality".
Some of them use green materials instead of traditional materials, some realize intelligent remote control through smart home appliances, some develop energy-saving air conditioning and refrigeration systems, and some build green supply chains. Coincidentally, these technology companies are integrating into the "carbon neutral" blueprint through innovation.
Based on this, Lei Feng. Com interview combed the gameplay and highlights of some China science and technology enterprises that are at the forefront of carbon neutrality.
Lenovo: left-handed green materials, right-handed technological innovation
As a high-tech manufacturing enterprise in China, Lenovo not only achieves low-carbon development with Lenovo characteristics by creating energy-saving and environmental-friendly green products, promoting circular economy, promoting energy-saving and environmental protection and green technological innovation, but also guides and drives the whole industrial chain to achieve low-carbon transformation through green manufacturing and green supply chain system.
In terms of green materials, from 2007, Lenovo began to apply plastic recycling technology to Lenovo's desktop, notebook, monitor, server and other products, reducing carbon emissions by about 60,000 tons, equivalent to planting more than 3 million trees.
In terms of green packaging, Lenovo has taken the lead in introducing degradable bamboo and sugarcane fiber packaging technologies in the industry since 2008, reducing the consumption of packaging materials by 3 100 tons. In fiscal year 20 19/20 alone, the consumption of packaging decreased by 560 tons.
In terms of green energy, Lenovo also built a solar photovoltaic project in Hefei factory, which reduced carbon emissions by 6,284 tons, equivalent to planting 350,000 trees, through green projects such as photovoltaic phase I and phase II construction, air compressor energy efficiency improvement and heat recovery, water storage and low-carbon boiler transformation.
Aiming at the technological innovation in the production process, Lenovo popularized the new technology of low-temperature solder paste (LTS) in Lianbao Factory, a personal computer manufacturing base, which changed the problems of high heat, high energy and high emission in the electronic product manufacturing industry for more than ten years.
At present, low-temperature solder paste has been widely used in PC field, which can save up to 35% of carbon emissions and achieve annual carbon reduction 1087 tons.
At the same time, Lenovo's advanced production scheduling system (LAPS) can save more than 2,696 MWh of electricity and reduce more than 2,000 tons of carbon dioxide emissions by improving production efficiency and reducing idle production lines, which is equivalent to planting 1 1 000 trees every year.
In addition, these measures have also driven the overall transformation of Lenovo's supply chain enterprises.
Over the years, Lenovo has extended its emission reduction practice to tier-one suppliers and upstream and downstream enterprises in the industrial chain supply chain, prompting suppliers to commit themselves to emission reduction and increase the use of new energy.
Beauty: "Smart building" is a cut, and smart home appliances are a blessing.
Beauty helps carbon neutrality and chooses "intelligent building" as the starting point.
Intelligent building is known as the driving force for the high-quality development of smart cities and an indispensable part of "new infrastructure". With the "carbon dioxide emission peak" and "carbon neutrality" written into the government work report during the two sessions this year, how to reduce the energy consumption of HVAC systems has become the focus of attention in the industry.
Under the background of carbon neutrality, two requirements are put forward for building system products: first, greatly improve energy efficiency; The second is to respond flexibly to the demand for power grid regulation. Midea's sixth-generation heat recovery product, the ultra-wide three-tube heat recovery system introduced in 2020, can work in the ultra-wide range from MINUS 15 to MINUS 48 degrees Celsius, with high comfort, high energy efficiency, ultra-low temperature and small capacity.
At the same time, Midea released "Building the Next Generation of Smart Buildings by Controlling the Three Nervous Systems", focusing on the layout of the entire industrial chain of smart buildings and making efforts to build the three nervous systems of smart buildings.
Sun Jing, general manager of Midea's HVAC and Building Division, Shanghai Kong Mei Company, said that if buildings are compared to people, the purpose of Midea's HVAC and building is to build the mind, heart, skin, bones, respiratory system and metabolic system of the building, so that the building can become a living body with temperature, perception and thinking. Kong Mei (Shanghai Kong Mei Intelligent Building Co., Ltd.), which focuses on the beauty of intelligent buildings, is used to connect the "nervous system" of various organs.
Among them, Kong Mei's full range of building automation products, such as DDC controller, M-BMS building automation system and other air conditioning and weak current related software and hardware core products, can be understood as the "autonomous nerve" of the building; Secondly, based on industry scenarios, integrating business-specific systems, such as smart clinics and smart wards in hospitals, smart platforms for rail transit and efficient computer rooms, is the second largest nervous system-"peripheral nerves"; The third nervous system-"central nervous system" represents the whole life cycle service of intelligent building. Relying on the advantages of Midea Group's basic scientific research, pioneer research, innovation center, high-end manufacturing, project implementation and cooperation network, the company takes peace of mind, comfort, low carbon and efficiency improvement as its vision, realizes the integration from top-level design, construction and debugging to digital operation and maintenance platform, and finally creates a "smart building" belonging to users.
In addition, Midea actively develops foreign cooperation and joins hands with State Grid China Electric Power Research Institute to build the first batch of "carbon neutral" smart home appliances in the field of white electricity. The first batch of cooperative home appliances covers a variety of smart home appliances and will be introduced to the market this year to promote the "carbon neutrality" of the home appliance industry.

Gree's core technology is distributed in landmark buildings at home and abroad. The most impressive thing is that in 20 15, Gree Electric won the bid for the centrifuge procurement project in the Great Hall of the People on behalf of national brands, which was the first time that China national brand air-conditioning products settled in the Great Hall of the People.
According to relevant data, since the installation of Gree permanent magnet synchronous variable frequency centrifugal water chiller in 20 15, the annual electricity consumption in the Great Hall of the People has decreased by 3 10000 kWh, and the electricity saving rate is nearly 32%. At the same time, the environment of the computer room is obviously improved, and the highest noise is only 80 decibels, which fully reflects the social responsibility of national enterprises.
In addition to the great breakthrough and successful application of green and efficient refrigeration technology, Gree's smart home system is also optimized around the goal of "carbon neutrality".
For example, Gree Zero-carbon Healthy Home, based on Gree Photovoltaic G-IEMS local energy Internet system, allows the home to independently realize one-stop energy control of power generation, electricity storage, electricity consumption and electricity management, and create an environmentally friendly smart home system for all household appliances.
Haier: Deeply cultivate the park, and make concerted efforts at both ends.

Green Rice: Intelligent Control and Visual Data Management Mode
Traditional household equipment needs manual on-site operation. If you forget to turn off the air conditioner and turn off the lights when you go out, it will be a few kilowatt hours a day. Through smart home, you can remotely turn off the device through App and other means. Of course, App control needs to be manual and not smart enough.
Aqara has many sensor devices, including human body sensor, light sensor, door and window sensor, temperature and humidity sensor, etc. Through the use, the automatic control of the equipment can be realized. You don't need to do it yourself. The equipment can be automatically controlled according to the environment and your needs.
For example, when Aqara's high-speed human body sensor judges that there is no one at home, it can automatically turn off the lights, turn off the air conditioner, turn off the TV and so on. At night, the ambient temperature drops slowly, and when we turn on the air conditioner again, the air conditioner can be turned off automatically.
For example, Aqara's light sensor can automatically open curtains when the indoor brightness is too dark, and dim the lights when the indoor brightness is too bright to realize energy saving and emission reduction.
If the above functions are put in public space, the result is the same, and the larger the space, the more air conditioners for lamps and lanterns, the higher the management and labor costs, and the more obvious the intelligent management efficiency and energy-saving effect during the period.
Aqara's smart office solution in a science park in Beijing can automatically turn off the power and equipment in the designated area when no one is there every day. Every day when there is no one in the meeting room, it will not only automatically give up the meeting room for other people to make an appointment, but also automatically turn off all the equipment in the meeting room, and automatically start the patrol when someone comes to the meeting.
Most of Aqara's equipment has the function of power statistics, which can provide visual data management for enterprise users, so that users can intuitively understand the power consumption of each space, the environmental temperature and humidity, and the working state of each equipment, and it is convenient to understand the final energy usage, so as to carry out refined and optimized management.
