Air-conditioning can become a power station, home lighting does not need to spend a cent on electricity, will this become a reality?

　　 On July 6, Dong Mingzhu, chairman and president of Gree Electric, revealed the latest technology being developed by Gree Electric at the 2021 China New Consumer Brand Growth Summit.

Dong Mingzhu said that Gree is developing a new technology that can combine light energy, energy storage and air conditioning. The air conditioner becomes a power station. It does not need to go through the city grid or remote transmission. It gathers enough energy to generate electricity through air conditioning. ，While ensuring the cooling or heating of the air conditioner, the excess electric energy is stored, and all the lighting in the house at night does not need to spend a penny on electricity. After Gree conducts further research and uses all the energy, it can absolutely ensure that a family is completely self-powered. If the technology is applied globally, the global temperature can drop by half a degree.

　　If this technology can become a reality, the entire air-conditioning industry will undoubtedly take a big step, and for consumers, it will also get tangible benefits. However, how difficult is this technology to implement? The market has mixed opinions.

　　 Senior industrial economic observer Liang Zhenpeng told China Industry News that this model is already in the process of accumulating electricity through photovoltaic panels and then integrating it into a unified power grid. The generated electricity is used internally by some factories. But as Dong Mingzhu said, the use of photovoltaic energy storage devices to power the air conditioners and all lighting devices in the home can only be said to be still in the process of research and development. It wants to achieve large-scale civilian use and enter the homes of ordinary people. There is still a long way to go.

"At least in the next three to five years, consumers will still need to rely on the National Grid to power air conditioners. Because the photovoltaic energy storage power generation technology wants to achieve large-scale commercial use, in addition to dealing with some technical issues such as voltage and current. There are also some policy issues related to the State Grid, which are impossible to solve in the short term. As for Gree Electric, this technology will not produce or have a positive financial report in recent years. Or negative impact.” Liang Zhenpeng said.

　　 However, there are also some voices who believe that Gree Electric has long established a layout in the field of new energy. The 2020 annual report shows that the business scope of Gree's new energy sector includes photovoltaic storage DC air-conditioning systems, industrial and commercial energy storage, new energy DC appliances, energy Internet systems, and new energy auto parts. With Gree Electric's current R&D strength, it is not impossible to realize this technology quickly.

　　 However, for Gree Electric, the courage to develop and innovate is itself worthy of recognition. "Gree Electric's ability to combine solar energy, energy storage, and air conditioning is a very good point of innovation. It is also a vivid practice of energy saving and emission reduction from the source of production under the background of'carbon neutrality', regardless of the future of this technology Whether it can succeed or not is a brave attempt and exploration for the air-conditioning industry, and it will also play a certain enlightenment on the research and development of other air-conditioning companies." A person in the home appliance industry told China Industry News.
