The screw refrigeration compressor is the heart of the screw chiller , and the demand for screw refrigeration compressors on the market is equivalent to the demand for screw chiller. Based on the downstream industries such as the central air conditioning industry and the refrigeration industry Based on comprehensive understanding and analysis of the business climate, it is estimated that the average annual growth rate of the screw refrigeration compressor industry in the next five years is about 9.5% to 21%, and the market demand continues to be strong, which means that the demand for screw chiller units will also be Showing growth.
With the continuous improvement of people's requirements for the comfort of living and working environment, commercial central air conditioners have developed rapidly. Statistics from the central air-conditioning industry show that China's central air-conditioning market grew rapidly in 2004, with a growth rate of 47%. Driven by real estate development, department store warehousing and logistics, and large public building construction, the demand for commercial central air-conditioning industry continues to be strong. It is estimated that the average annual growth rate of sales of central air-conditioners will be about 12% to 19% from 2005 to 2010. As a result, screw units will be vigorously developed. In the field of central air-conditioning of medium-sized 30RT-500RT, screw compressors have gradually replaced piston compressors.
The level of industrial technology is becoming more and more stringent, and the demand for industrial refrigeration equipment has steadily increased. China's refrigeration industry accounts for about 19% of the entire refrigeration industry, which is far lower than the international mature market's ratio of about 39%. The market potential of the freezing and refrigerating industry is very high, especially the development prospects of low and medium temperature freezing and refrigerating equipment in the agriculture, fishing, and animal husbandry industries are very broad.
Refrigeration and refrigeration compressors can be divided into small refrigeration refrigeration compressors and large and medium-sized refrigeration refrigeration compressors. Among them, small refrigeration refrigeration compressors are mainly used in refrigerators (reciprocating and rotary structures are mainly used, and frequency conversion technology is the future development direction) and refrigeration vehicles (Vehicle-type screw compressors are the direction); large and medium-sized refrigerating and refrigerating compressors are mainly used in railway refrigerated trucks, refrigerated ships, refrigerated containers and cold storage, mainly reciprocating and screw-type. Screw compressors are suitable for 24-hour operation for a long time, and the technology used in low-temperature systems has continued to improve. Its performance and efficiency have been greatly improved. In developed countries such as Europe and the United States, screw compressors have gradually begun to be used in low-temperature refrigeration and refrigeration systems. Replaces the traditional piston type as a standard configuration.
Supply and competition pattern of screw refrigeration compressor industry Screw refrigeration compressor industry is a technology-intensive industry with relatively complex production processes, high processing accuracy requirements, and difficulty in updating products and technologies. The sustainable development of enterprises requires both R & D Strength and technical reserves also require a certain accumulation of practical experience. At present, domestic screw compressor manufacturers have improved the technical content and performance quality of their products through technology introduction, technical cooperation or independent research and development. However, compared with international advanced levels, their products are still in terms of profile, noise, and oil separation efficiency. There is a gap. Therefore, there is still considerable room for improvement in the quality of domestic screw refrigeration compressors, and there are also many opportunities and opportunities!
