The water-cooled screw compressor utilizes a semi-hermetic screw compressor, offering advantages such as stability, reliability, low noise, and low vibration. During the compression process, gas enters the compression chamber from the suction end of the screw, and as the screw rotates, the gas is gradually compressed and eventually discharged through the exhaust end. The thread shape and rotational motion of the screw ensure the continuity and stability of the gas during the compression process. Bitzer or Hanbell, two globally renowned brands, provide the screw compressors used in the Xiecheng water-cooled screw compressor, ensuring long-lasting, efficient, and stable operation. Compared to traditional scroll compressors, it achieves energy savings of over 20%, resulting in more energy-efficient operation.
Features：1. 20% Energy Saving 2. low Noise 3. Low Vibration

Screw compressors feature stepless capacity control, which means that a single compressor can continuously adjust the cooling capacity in any range between 25% to 100%. This allows for precise control of energy output, ensuring stable and efficient operation.

The Water Cooled Screw Chiller utilizes a shell and tube evaporator. In this system, the refrigerant evaporates inside the heat exchange tubes, while water flows on the shell side. To enhance the heat exchange efficiency, a 2mm thick baffle plate is installed on the shell side, causing the water to flow back and forth to create ice brine. Additionally, to maintain a stable operating temperature, the exterior shell of the evaporator is covered with insulation material.
For the heat exchange tubes, we employ high-efficiency seamless copper tubes. These tubes undergo a grooving process to form internal thread fins, thereby increasing the heat exchange surface area with the refrigerant. With this technology, the heat transfer area is doubled, significantly improving the heat transfer efficiency.

Water Cooled Screw Chiller utilizes a shell and tube condenser, with the internal copper tubes employing an outer thread embossing process. This design effectively enhances the heat exchange efficiency between the refrigerant and water during the process. Compared to traditional smooth copper tubes, the outer thread embossing process increases the surface area of the copper tubes, thereby expanding the contact area for heat exchange and improving the thermal conductivity of the condenser. This optimization design allows the condenser of the water-cooled chiller to transfer heat from the refrigerant to the water more rapidly and consistently, enabling the water to carry away the heat.
