Heat accumulation in industrial manufacturing not only impairs product quality but also severely constrains production efficiency. As the core equipment for removing thermal loads, refrigeration chillers precisely absorb heat from process circulating water using the principle of phase-change heat absorption by liquid refrigerants. In large-scale manufacturing bases and centralized cooling systems, large-scale chillers serve as essential infrastructure to ensure the continuous operation of entire production lines, with screw chillers commonly powering their core. The unique twin-rotor stepless regulation structure of screw compressors grants these units exceptional part-load efficiency and extremely low failure rates, making them the preferred solution for high-capacity, continuous cooling....
