    Frozen Refrigeration Units Market conditions

    One or two models of the profile:

    Centrifugal chiller: Centrifuge is to rely on the centrifugal compressor in the high-speed rotation of the impeller to produce centrifugal force to improve the refrigerant vapor pressure to obtain the steam compression process, and then by condensing throttle buck, evaporation and other processes to achieve refrigeration , The main components of which are centrifugal compressors, evaporators, condensers, throttle, evacuation units, lubrication systems and electrical control condensers, throttling mechanisms, pumping recovery equipment, lubrication systems and electrical control cabinets, etc. The It has a single machine cooling capacity of the characteristics, but there is too high pressure sealing problem is difficult to solve, the work of high speed and other shortcomings.

    Screw chiller: screw machine is a more advanced technology of a model. It is the use of screw-type compressor in the two Yin, Yang rotor meshing, in the case of rotation to complete the suction, compression and exhaust process. Its components are screw compressors, condensers, evaporators, thermal expansion valves and other control components, less than the centrifuge. It has the characteristics of compact structure, reliable operation balance, less wearing parts, high partial load efficiency and long service life.

    Second, the two units of the market situation:

    Centrifugal chiller: As the centrifugal chiller for the relatively narrow market range, 2008 centrifugal chillers market sales of about 2.5 billion level, only the central air conditioning market capacity of 10%.

    Analysis of the entire domestic market sales of centrifugal units production enterprises, sales of more than 300 million enterprises only a few, mainly concentrated in several major European and American brands, the past few years there are some enterprises to enter the market, but also made some achievements.

    As the centrifugal unit production enterprises not much, the overall profit is still considerable. In recent years the annual growth rate of centrifugal units in the market are about 15%.

    Screw chillers: Screw chillers have many technical advantages, such as high efficiency, low noise, low vibration, high reliability, less wearing parts, smooth operation, etc., are widely used in hotels, shopping malls, hospitals and modern generation Of the factories and office buildings of the refrigeration and air conditioning works.

    2008 screw machine sales of about 5.6 billion, accounting for about 37% of all market sales, the equivalent of centrifuges, water reactors and modules and the sum of the machine.

    The screw machine market is now "polarized" state, its capacity toward the larger and smaller direction.

    China's first emerging central air-conditioning products is water-cooled screw unit, the advantage is energy efficient. At present, all types of domestic buildings are used in most of the water-cooled screw unit. Now, building energy efficiency has been listed as the focus of future energy work, water-cooled screw unit efficient energy-saving advantages to make it once again a hot sales, the development prospects are very optimistic.
