  Dong Mingzhu Calls for Standardization Construction

The 10^th Plenary Meeting of ISO/TC86/SC4 Subcommittee of Testing and Rating of Refrigerant Compressors (ISO/TC86/SC4) was officially held on February 21. Delegations from 9 countries, 4 ISO officers, foreign experts and the Chinese delegation attended this meeting. This was the first time for Dong Mingzhu, Chairperson and President of Gree Electric Appliances, to meet the members as the chairperson of ISO/TC86/SC4 subcommittee.

Dong: Promoting the standardization construction to guide industrial development

As a standardization worker from the manufacturing industry, Dong has fulfilled the responsibilities of chairperson of international standardization committee according to the related stipulations of ISO earnestly since she took office, and contributed “Chinese Wisdom” on the international stage actively.

Now, standardization construction has been regarded as core competitiveness among first-class enterprises. So is the competition among countries. To some extent, standards have become a global “common language”.

Currently, as the consumption is upgrading, the demand for refrigeration products is increasing year after year. As compressor is the core parts of refrigeration products, its sales volume will increase continuously. Under the goals of “carbon neutrality” and “peak carbon emissions”, the massive demands of high energy-consuming compressors have brought great pressure. The compressor standards established in the past no longer meet the current demands for green development. It’s imperative to set up new international standards to lead the technological innovation of compressors, and realize energy conservation and emission reduction of refrigeration products.

“The subcommittee of ISO/TC86/SC4 shall play its leading role completely, call upon the member states to make contributions actively and participate in formulating standards, and boost energy conservation and efficiency of refrigeration products with standards, thus realizing the sustainable development of the refrigeration industry,” said Dong.

Technologies and talents are the important resources for enterprises, industries, even the competition and development of a nation, while patent standardization, technology standardization, internationalization and industrialization of standards are the important strategic targets for innovative development. Dong plays an important promotion role in many aspects, such as inspire the Chinese professionals to participate in standards formulation, lay down and supervise the international standards for refrigeration compressors, make the standards of “Made in China” international, etc.

Inject “Chinese Wisdom” for international standards with technology strength

By cooperating with Hefei General Machinery Research Institute Co., Ltd. and Tsinghua University, Gree put forward two proposals on compressor field during the conference. At present, the essence of standards construction competition is mainly about core technology and innovative ability. In recent years, the achievements of Gree in standards formulation have demonstrated that mastering core technologies is mastering the initiative for standards formulation.

The group standard of China Power Supply Society, T/CPSS 1005-2021 Technical Specification of Impedance Sweeping Equipment of Low Voltage DC Distribution and Utilization System, which Gree has participated in drafting, was officially launched on August 27, 2021. It stipulates the composition, working condition, technical requirement, test method, test rules, logo of impedance sweeping equipment of low voltage DC distribution and utilization system, which does not only provide effective samples for the low voltage DC technology, but also assist the future exploration on low voltage DC technology. On December 3, the draft of the final version of proposal IEC TS 63349-2 Photovoltaic Direct-driven Appliance Controllers  Part 2: Operation Modes and Graphic Display on photovoltaic international standards, which is led by Gree, passed with high votes in IEC/TC 82, and was unveiled in the February of 2022 according to the process and standards. It’s learned that the IEC TS 63349-2 is the first international standards in the photovoltaic direct-driven appliances industry. Its launch will fill the gap of industry standards, and provide basis for the design, detection and attestation of photovoltaic direct-driven appliances.

“China is not only a large air conditioner producer, but also a big air conditioner consumer. In the refrigeration industry, the number of Chinese standards, no matter on equipment or components, is far ahead when compared with other countries. Its evaluation methods of some standards, which are representative and progressive among the standards of international refrigeration industry, are adopted by the international counterparts. That plays a good role in inspiring the Chinese enterprises to innovate independently, and encouraging them to participate in formulating the international standards,” said Li Jiang, director of China Refrigeration and Air-conditioning Industry Association and leader of the Chinese Delegation.

Focus on the Future of the industry

“Standard is a technical support for economic activities and social development. It’s an important measure to lead technology innovation and realize energy conservation and emission reduction by standards, as well as promote the high-quality development of the industry and cope with climate change, ” said Dong.

As China is stepping forward to a powerful country in the world, there are more and more countries focusing on the stance of China. What China should do is not overturn the current situation, but drive the Chinese standards to the world and accelerate an integrated system for international standards.

Some of you might wonder: what does an entrepreneur of China’s manufacturing industry acting as the subcommittee chairperson of ISO mean? Actually, for the Chinese standards, it means an extra channel and a bridge to the world. When we have more and more communication platforms to demonstrate our advantages on the international stage, the establishment and promotion of “Chinese Wisdom” will enhance the confidence of “Made in China”, supervise the manufacturing industry and create a good innovation environment for the high-quality development of the Chinese manufacturing industry.

International standard is a critical technology basis for global economic and trade cooperation and development. Under the background of economic and trade globalization, the role of international standards is increasing daily. Our country and all industries have introduced related supportive policies successively, providing the principle for the development of standardization in a new era. We believe that, standing at the beginning of a new era, the Chinese enterprises will make greater contributions to a harmonious world with technology innovations, and the Chinese standards will shine on the global stage by virtue of its fairness and rationality.
