1. Selecting a semi enclosed screw compressor, compared to traditional reciprocating compressors, it has the characteristics of stability, quiet operation, simple operation, and long service life; 2. Adopting refrigeration components to ensure stable quality and operation of the unit; 3. The evaporator and condenser both use the latest high-efficiency threaded heat exchange copper pipes, with high heat transfer coefficient. At the same time, the evaporation inside the pipes and condensation outside the pipes have high heat transfer efficiency, and the unit has good refrigeration performance; 4. The refrigeration circuit can be maintained and repaired separately without affecting the use of the entire machine; 5. The unit can achieve intelligent program control to save energy consumption according to the demand of the load; 6. Complete safety protection functions ensure stable operation of the machine; 7. The unit has less vibration, and the foundation does no…
