Air cooled screw chiller

Air cooled screw cold water机组Technical characteristics

1, the unit compressor adopts 5:6 asymmetric double screw air cooled compressor，This type of compressor is the current good form of screw compressor，The performance is better than repeated compressors and single screw compressors，It has the advantages of high energy efficiency ratio, long service life (operating life of 100000 hours), low failure rate and easy maintenance。Widely used in commercial air conditioning field;

2, the unit evaporator uses high efficiency shell and tube heat exchanger, and the internal heat exchange copper tube uses internal thread copper tube;The condenser adopts high efficiency copper tube + hydrophilic aluminum warping plate type。Imported plate processing, with high pressure grade, high heat exchange efficiency, maintenance-free, long service life and other advantages;

3, the unit adopts Siemens control system。Adopt good PLC control technology, can accept programming, and has perfect communication function, can be convenient and building intelligent control system docking;

4, the unit adopts Siemens, Schneider and other brands of electrical components, waterproof control cabinet;

5, the unit uses Siemens touch LCD screen, Chinese and English human-machine interface, simple operation procedures, one-click start, automatic operation;

6, the unit adopts a complete set of Siemens control system, with NULE independent research and development of the unit energy saving control program, to ensure that the unit according to the set working conditions, automatic adjustment of compressor operation, winter heating can automatically defrost treatment, to ensure the smooth operation of the unit, energy saving;

7, the unit structure is simple, with a good man-machine interface, within the safe operation range of the unit, the unit can be freely set operating conditions, once set, the unit can run by itself and real-time energy understanding，Easy to operate。
