With the passage of time, as well as more and more enterprises to join the competition in the centrifuge market, China's centrifugal machine market structure changes will also be accelerated.
In recent years, with the continuous changes in market demand, sales of centrifugal chillers gradually increased, the market size continues to expand. Today, the country vigorously promote environmental protection, and manufacturing technology is more and more mature, it can be seen, energy saving will become the future development trend of centrifugal chillers.
Centrifuge as the central air-conditioning industry has the most core technology products, has been a high threshold, the technical difficulty and other characteristics. It is therefore, centrifuges and even the whole industry is concerned about the industry. In recent years, a number of domestic professional enterprises have invested resources in the central air conditioning technology in the field of centrifuges, and continue to represent the central air-conditioning the most high-end technology in the field of attack, has increasingly become the development trend of China central air conditioning enterprises.
With the development of society, the user needs more and more cold, in addition to the requirements of energy-saving centrifugal unit has more and more broad market. Some domestic air conditioner manufacturers such as Haier, GREE, Australia Kema and the United States have launched their centrifugal chillers.
Most of the domestic development of centrifugal chillers to buy imported compressors, basically no profit. Foreign centrifuge manufacturers will not easily sell their core technology, in order to develop a centrifugal refrigeration compressor, take the road of independent development. With the development of the design and manufacture technology, it is possible to develop the domestic centrifugal refrigeration compressor.
It is reported that the molecular weight of the refrigerant centrifugal chillers are large, low speed, M Maher number in the flow passage of the compressor is relatively high, which requires special attention in the impeller configuration of air flow organization, to avoid or reduce the flow in the impeller flow by the shock losses, while adapting to the volume flow of the refrigerant gas changes greatly the characteristics in the impeller.
With the increasingly tense energy, energy saving and consumption reduction is a major trend of product development. In addition, due to the continuous improvement of China's urbanization, building energy consumption continues to increase. With the highest performance coefficient of centrifugal chillers will undoubtedly become a hot market, in recent years, the sales of centrifugal chillers continue to improve.
