Compared with the development of heat pump in the world, the research of heat pump in China started 20 ~ 30 years later. Since 200 1, China's heat pump industry has changed from an introduction period to a growth period. The rapid development of heat pump industry, on the one hand, benefits from energy shortage, making the advantages of heat pump energy saving more and more obvious, on the other hand, it has a lot to do with the participation of many forces in promoting industrial technological innovation.
After 2009, China Municipal Government issued a series of policies to help green energy conservation, such as subsidies for energy conservation and benefiting the people, subsidies for large-scale government energy conservation projects, and corporate tax subsidies. Nongtai seized this opportunity and tried a number of technical innovations in the heat pump industry, such as cloud thermonuclear technology, 3X rapid heating technology, vacuum insulation technology, ultra-low temperature enhanced steam injection technology, multi-tank multiple heat exchange technology, phase change heat storage technology, microchannel heat exchange technology, DC frequency conversion technology and other technical solutions, which attracted the attention of the industry and consumers.
At present, the key core technologies of large-scale dual-temperature ground source heat pump, water source heat pump, high-temperature heat pump and multifunctional heat pump in China are solved by China heat pump experts, who have completely independent intellectual property rights. The number of patents on heat pump technology in China has been far ahead of the world. Moreover, China's heat pump technology is the only country that has been successfully applied in Antarctica.
