Centrifuge as the core technology is the central air-conditioning industry products, always has the characteristics of high threshold, great technical difficulties. It is therefore, centrifuge is corporate and industry wide attention. In recent years, a number of domestic professional central air conditioning enterprises have invested resources in the field of centrifuge, and continue to represent the central air-conditioning the most high-end technology in the field of attack, has become the development trend of China central air conditioning enterprises.

随着社会的发展，用户需要的冷量越来越高，另外由于节能的要求使得离心机组具有越来越广的市场。一些国内空调厂家如海尔、澳克玛、格力及美的纷纷推出自己的离心式冷水机组。国内大部分开发离心冷水机组的企业购买进口压缩机,基本上没什么利润。国外离心机厂家不会轻易出让自己核心技术,要想研制离心式制冷压缩机,走自主开发道路。设计及制造技术的不断成熟,使国产离心式制冷压缩机研制成为可能。据悉，离心式冷水机组采用的制冷剂的分子量都很大，音速低，在压缩机流道中的马赫数M比较高，这就要求在叶轮构型时特别注意气流组织，避免或减少气流在叶轮流遭中产生激波损失，同时适应制冷剂气体的容积流量在叶轮内变化很大的特点。

With the development of society, more and more cold quantity of user needs, in addition to the energy requirements of the centrifugal machine has more and more wide market. Some domestic air conditioner manufacturers such as Haier, Australia Kema, Gree and beauty have launched the centrifugal chiller own. Most of the domestic development of centrifugal chillers enterprises to purchase imported compressor, basically no what profit. Foreign centrifuge manufacturers will not easily transfer their core technology, to the development of centrifugal compressor, independent development road. Design and manufacturing technology continues to mature, so that the domestic centrifugal compressor development become possible. It is reported, the molecular weight of the refrigerants in centrifugal chillers are very low, sonic, M Maher number in the compressor flow is relatively high, which requires special attention in the impeller configuration of airflow organization, avoid or reduce the flow in the impeller stream generated by shock losses, while adapting to the volume flow rate of refrigerant gas changes greatly features in the impeller.

随着能源的形式日趋紧张，节能降耗是产品发展的一大趋势。另外由于中国城镇化水平的不断提高，建筑能耗不断增加。具有最高性能系数的离心冷水机组无疑将成为市场的热点，近年来离心冷水机组的销量不断提高。

With the form of energy shortage, energy conservation is a major trend of product development. In addition to the Chinese continuous improvement of the urbanization level, building energy consumption will continue to increase. Centrifugal chiller with the highest coefficient of performance will undoubtedly become a hot market, in recent years, centrifugal chiller sales rising.

随着时间的推移以及越来越多的国内企业加入到离心机市场的竞争中来，中国离心机组市场格局的变化也将随之加快。国内的制冷企业要高举民族工业的旗帜，研制出真正意义上的国产化离心式制冷压缩机精品。

With the passage of time, more and more domestic enterprises to join the centrifuge market competition, changes in the market structure China centrifugal unit will also speed up. Refrigeration domestic enterprises to hold high the banner of national industry, developed the domestic centrifugal compressor works on real significance.
