For my country's air-conditioning and refrigeration industry, after half a century of development, especially the rapid development of 30 years of reform and opening up, various infrastructures are very complete, which has laid a solid foundation for further development in the future. If industry resources can be better allocated and utilized, outdated products can be eliminated, the full development of energy-saving and environmentally-friendly product market applications can be promoted, the research and development of core technologies can be increased, the overall strength of my country's refrigeration and air-conditioning industry can be improved, and the country will become a world refrigeration power The list will be just around the corner.

　　 The central air-conditioning industry has obvious characteristics of expanding the scope of market demand, especially in terms of geography, climatic conditions, purchasing power, and consumption concepts. The domestic market has a large climate span, such as the difference between north and south, and the demand for central air-conditioning also reflects the demand trend from the difference. It can be seen that North China and East China, represented by Beijing and Shanghai, are political and cultural centers and radiation areas. The main office buildings are investment, and the central air-conditioning market is mostly concentrated here; Guangdong, represented by Guangzhou and Shenzhen, is characterized by trade operations, and real estate investment is mainly commercial buildings. With the help of the "municipalities directly under the Central Government" effect, the scale of real estate investment in Chongqing has increased rapidly, especially in commercial business users. Therefore, the application of central air-conditioning in Guangdong, Chongqing and other regions is mainly concentrated in commercial business rooms.

　　 At present, with the rapid economic development of various regions, the regional market demand for central air-conditioning products will steadily increase. At the same time, office buildings, hotels, commercial centers, cultural and entertainment centers, national defense, scientific research, laboratories, hospitals, special industrial plants and facilities in various regions will have a broader development in the direction of central air conditioning.

　　 The refrigeration and air-conditioning industry has changed its production methods and adjusted its product structure with changes in national policies. It can be seen from the adjustment of the company's product structure that energy-saving products have become the key R&D content and main product of the company.

　　 In order to achieve the goal of energy conservation and environmental protection of equipment, all enterprises have carried out related activities around the theme of energy conservation and environmental protection, and increased investment in new product development, product design, manufacturing technology, and technological transformation of production lines to promote equipment upgrades. At the same time, energy-saving is also emphasized in production, and all enterprises have formulated a sound evaluation system to strive to reduce energy consumption under the premise of increased production capacity, and minimize the emission of pollutants in the intermediate links of production.
