Hainan Haishen Tongzhou Pharmaceutical Co., Ltd. from Haikou City, Hainan Province

The project requires a water-cooled screw chiller unit with high precision in outlet water temperature control. The system should integrate automatic control of the chilled water pump, cooling water pump, and cooling tower, enabling advanced interlinked operation and seamless network connectivity. To achieve precise and stable outlet water temperatures with minimal fluctuations, our company has adopted a variable-frequency screw compressor solution. By using a frequency converter to precisely regulate the compressor’s rotational speed, the chiller can automatically adjust its power output based on the actual cooling load requirements. Under variable-frequency control, the screw compressor delivers stepless speed adjustment, effortlessly adapting to varying operating conditions while maintaining optimal performance at all times. This not only ensures high efficiency and energy savings but also minimizes the inrush current and reduces the impact on the power grid. Additionally, the advanced integrated control system seamlessly manages the chilled water pump, cooling water pump, and cooling tower, featuring user-friendly one-touch startup functionality for fully automated operation. Furthermore, the system includes an IoT service module and an RS485 communication interface, allowing easy integration into centralized control systems. This enables the implementation of "smart building" solutions as well as "industrial internet" applications, enhancing overall operational efficiency and connectivity.
