1. Nuclear power is a clean energy with mature technology. Compared with thermal power, nuclear power does not emit sulfur dioxide, soot, nitrogen oxides and carbon dioxide. Replacing part of coal power with nuclear power can not only reduce the total amount of coal mining, transportation and combustion, but also an effective way to reduce pollutant emissions from the power industry and an important measure to slow down the greenhouse effect. thorium. Nuclear power development, equipment guarantee. Nuclear power equipment includes nuclear islands, conventional island equipment, and operation and maintenance facilities to meet the needs of nuclear power plant infrastructure construction and waste disposal. Refrigeration equipment is an indispensable part of the equipment required for conventional islands. However, because domestic companies have not yet been able to manufacture dedicated centrifugal nuclear power units, their supply has been strictly controlled by foreign companies.

2. In this case, Gree acts as a "charging circuit breaker" and a "circuit breaker". As a member of the Chinese refrigeration industry, Gree is very brave in the core equipment of nuclear power plants. After several years of development, major breakthroughs have been made in the development process in design, prototype manufacturing, performance testing and quality assurance system. In 2015, successfully developed a one-million-kilowatt nuclear power plant. On the basis of the heart-shaped chiller (fixed frequency), the first million-kilowatt water-cooled centrifugal chiller (frequency conversion) and one-million-kilowatt nuclear air-cooled screw chiller were introduced, which not only realized the localization of large-capacity R . Nuclear power plants also set an example for the comprehensive localization of HVAC systems in nuclear power plants. Shanghai air conditioning design

3. At the site, experts agreed that Shanghai Air Conditioning has developed innovative points of air-cooled screw chillers, integrated -C 40 reliable refrigeration operation technology, high-efficiency twin screw compressor design, large refrigeration capacity and small load and Constant water design, earthquake resistance and W. Resistance structure design, high corrosion protection, high reliability design. Aiming at the technical problems of nuclear air-cooled screw unit with wide ambient temperature range (-C 40～46.1 C), large cooling capacity (1136kW) and variable load (10%～100%), a series of key technologies and schemes have been proposed.

 4. The other unit is completed by the on-site 1 million kilowatt nuclear power water-cooled centrifugal chiller (frequency conversion), with completely independent intellectual property rights, filling the research gap at home and abroad. Compared with fixed-frequency units, Gree VVVF core coolers are more energy-efficient, each unit can save about 2 million electricity per year, and has superior performance and reliability. According to China's 2015-2019 nuclear power unit approval, Gree's frequency conversion nuclear cooling unit is expected to reach 44 market shares in the next four years, with excellent performance and reliability advantages, and the total market share will reach 220 million yuan.
