Air cooled screw refrigeration unit set
The performance of air-cooled screw refrigeration units is superior to that of reciprocating compressors and single screw compressors, with advantages such as high energy efficiency, long service life (100000 hours of operation), low failure rate, and easy maintenance. Widely used in the field of commercial air conditioning; 1. The unit compressor adopts the internationally renowned brand 5:6 asymmetric twin-screw air-cooled dedicated compressor, which is currently the most advanced form of screw compressor in the world. Its performance is superior to that of reciprocating compressors and single screw compressors, and it has the advantages of high energy efficiency, long service life (100000 hours of operation), low failure rate, and easy maintenance. Widely used in the field of commercial air conditioning;
2. The unit evaporator adopts an efficient shell and tube heat exchanger, and the internal heat exchange copper tube adopts an internally threaded copper tube type; The condenser adopts high-efficiency copper tubes and hydrophilic aluminum fins. All are processed using imported sheet metal, which has the advantages of high pressure resistance, high heat transfer efficiency, maintenance free, and long service life;
3. The unit adopts Siemens control system. Adopting advanced PLC control technology, it can accept programming and has complete communication functions, making it easy to interface with building intelligent control systems;
4. The unit adopts electrical components from international brands such as Siemens and Schneider, and uses waterproof control cabinets;
5. The unit adopts Siemens touch screen LCD display, with a Chinese English human-machine interface, simple operating procedures, one click start, and automatic operation;
6. The unit adopts a Siemens complete control system, equipped with HALEN's independently developed energy-saving control program, to ensure that the unit automatically adjusts the operation status of the compressor according to the set working conditions. In winter, the heating system can automatically defrost, ensuring smooth and energy-saving operation of the unit to the greatest extent possible;
7. The unit structure is simple and has a good human-machine interface. Within the safe operating range of the unit, the operating conditions of the unit can be freely set. Once set, the unit can operate on its own and perform real-time energy monitoring, making the operation simple.
