Current status and development direction of Chinese air-conditioning compressor manufacturing industry

Current status and development direction of Chinese air-conditioning compressor manufacturing industry The refrigeration compressor is the core and heart of the refrigeration system. The capacity and characteristics of the compressor lead to the capacity and characteristics of the refrigeration system. The most direct and effective way to improve the efficiency of the refrigeration system is to increase the efficiency of the compressor, which will bring a significant reduction in system energy consumption. At the same time, it can also avoid collecting only on the system. There are many types of compressors. According to different working principles, refrigeration compressors can be divided into fixed displacement compressors and variable displacement compressors. In recent years, with the rapid development of the international refrigeration compressor industry, the concentration of the global compressor market has gradually increased. Leading compressor manufacturers have continuously improved their competitiveness through industry integration, gradually appearing in Germany ’s Bitzer and the United States Ingersoll. Industry leaders such as Lan represent the dominant market position. At present, there are many refrigeration compressor enterprises in China, and the vast majority are engaged in the production of low-end refrigeration compressors. The main core components of most companies producing spiral refrigeration compressors, the double spiral rotor (accounting for more than 25% of the total cost), basically rely on imports. It is precisely because most domestic enterprises do not have core technology and can only provide complete machine products, which largely inhibits the development of the domestic refrigeration compressor industry. At present, most of China's refrigeration compressor market is mainly occupied by some refrigeration companies in Europe, Japan and the United States. With the development of society, the amount of cooling required by users is getting higher and higher. In addition, due to the requirements of energy saving, centrifugal units have an increasingly wider market. With the increasingly tense form of energy, energy saving and consumption reduction is a major trend in product development. In addition, due to the continuous improvement of China's urbanization level and the increasing energy consumption of buildings, the centrifugal chiller with the highest performance coefficient will undoubtedly become a hot spot in the market. In recent years, the sales volume of centrifugal chillers has continuously increased. Most Chinese companies that develop centrifugal chillers only buy imported compressors, and basically have no profit. Foreign centrifuge manufacturers will not easily sell their core technologies. To develop refrigeration compressors, they have to take the path of independent development. With the continuous maturity of design and manufacturing technology, the development of domestic centrifugal refrigeration compressors has become possible. As China has gradually become a global manufacturing center, the center of global compressor manufacturing has gradually shifted to mainland China, and major international compressor manufacturers have entered the Chinese market. Currently, the world's major compressor manufacturers have production bases in China. The major international compressor manufacturers attach great importance to development in China, and China has become one of Bitzer's important global markets. The entry of major international compressor manufacturers into China has intensified market competition in China's refrigeration compressor industry. At present, China has become the world's largest producer and consumer of air conditioners and compressors. With the upgrade of consumption and product upgrade opportunities, China's domestic air conditioners will usher in a further improvement in product quality, products will develop in the direction of high efficiency, frequency conversion, comfort, health and intelligence, and the compressors essential for air conditioning will also be accompanied by further air conditioning. development of
