In 2017, the Chinese room air conditioner industry witnessed a transformative year, marked by significant policy changes, international collaborations, and a strong push toward environmental sustainability. Several key initiatives were launched, reflecting China's growing commitment to global environmental protection and its role in shaping the future of the industry.
One of the most notable developments was the launch of the second phase of the HCFC (Hydrochlorofluorocarbon) phase-out management plan for the room air conditioner and domestic heat pump water heater industry. This initiative, supported by the United Nations Industrial Development Organization (UNIDO), the Italian Ministry of Environment, the Chinese Environmental Protection Cooperation Center, and the China Household Electrical Appliances Association, took place in Shanghai on March 11, 2017. The meeting officially kicked off the second phase of the phase-out, which aimed to accelerate the reduction of HCFCs. By 2018, a 20% cut from the baseline was planned, with a further 45% reduction by 2020—surpassing previous targets.
As part of this transition, the industry also faced critical decisions regarding refrigerant replacement technology. With global and domestic policies shifting toward ozone-friendly and low-carbon alternatives, R290, a hydrocarbon refrigerant, emerged as a promising option. The second phase saw an accelerated adoption of R290, with plans to convert at least 20 production lines for R290 room air conditioners and three compressor lines.
In April 2017, two important industry standards were implemented: QB/T 4975-2016 and QB/T 4976-2016, focusing on the safe use of flammable refrigerants in household air conditioners. These standards, developed under the supervision of the Ministry of Industry and Information Technology, set clear guidelines for production, operation, and safety management, filling a critical gap in China’s regulatory framework.
An international symposium on R290 refrigerant applications was held in Ningbo, Zhejiang, in April 2017. Organized by several international agencies and the China Household Electrical Appliances Association, the event brought together representatives from Southeast Asia and the Middle East. It showcased China’s progress in adopting R290 and reinforced confidence in the global shift toward environmentally friendly refrigerants.
The EU Fluoride Gas Act became a major concern for Chinese manufacturers in 2017. As the EU tightened regulations on fluorinated gases, including HFCs, Chinese companies faced increasing challenges in exporting to Europe. The act required quota management for imported HFCs, making it more difficult and costly to access the EU market. This pushed Chinese manufacturers to explore greener alternatives like R290.
In September 2017, the 30th anniversary of the Montreal Protocol was celebrated in Beijing. Premier Li Keqiang emphasized China’s commitment to the Kigali Amendment, which aims to reduce HFCs globally. The event highlighted China’s leadership in promoting green technologies and its alignment with international environmental goals.
A major international exchange meeting on R22 alternative technology was held in Hefei in November 2017. The conference, organized by multiple international bodies, provided a platform for Chinese manufacturers to share their technical proposals, particularly the use of R290 as a sustainable refrigerant. This strengthened China’s position in the global dialogue on refrigerant alternatives.
The Kigali Amendment, adopted in 2016, reached the threshold for entry into force in 2017, with implementation scheduled for January 1, 2019. Developed countries would begin reducing HFCs from 2019, while developing nations, including China, would freeze consumption in 2024 and start reductions in 2029. This timeline posed challenges for China’s air conditioning industry, as it needed to adapt quickly to remain competitive in global markets.
In November 2017, the Ministry of Environmental Protection and the China Household Electrical Appliances Association were honored with international awards for their contributions to ozone layer protection. Their efforts were recognized by the United Nations Environment Programme and the Canadian government, underscoring China’s pivotal role in global environmental governance.
Finally, the revision of IEC international standards for refrigerant leakage made significant progress in 2017. As the world’s largest manufacturer of air conditioners, China played a key role in advocating for more flexible and science-based regulations that support the use of flammable but environmentally friendly refrigerants like R290.
Overall, 2017 was a landmark year for the Chinese air conditioning industry, characterized by bold steps toward sustainability, stronger international collaboration, and a clear vision for a greener future.
This series features transparent LED screens, which are suitable for various indoor places and various stores, especially in storefronts with floor-to-ceiling glass windows. Installing the transparent screen against the glass wall has a very good effect. When the display is turned off, the audience can watch the indoor environment from the outdoors, and when the display is turned on, they can directly watch the content played on the display.It not only preserves the visibility in the store, but also can effectively display advertising videos to the other party, which is very practical.
