Semi-Enclosed Screw Compressor

Low Noise and Vibration, Over 20% Energy Savings
The air-cooled screw chiller uses a semi-enclosed screw compressor, featuring stable operation, low noise, and minimal vibration. During the compression process, gas enters the compression chamber from the suction side, is continuously compressed as the screw rotates, and is discharged from the exhaust side. The screw's structural design ensures smooth and efficient gas flow. The equipment uses internationally renowned screw compressor brands such as Bitzer or Hanbell, ensuring long-term, efficient, and reliable operation. Compared with traditional scroll compressors, the overall energy-saving effect is improved by over 20%, significantly reducing energy consumption.

Shell-and-Tube Evaporator

The air-cooled chiller uses a high-efficiency shell-and-tube evaporator, where the refrigerant evaporates inside the heat exchange copper tubes while water flows on the outside of the shell. To improve heat exchange efficiency, we have added a layer of approximately 2mm thick baffle inside the shell, causing the cooling water to flow back and forth, thereby enhancing heat transfer efficiency and achieving the effect of producing brine water.

The exterior of the shell is wrapped with high-performance insulation cotton to reduce energy loss and ensure stable system operation and consistent temperature.

The evaporator uses high-efficiency seamless copper heat exchange tubes. The copper tubes undergo precise 'Yuhua' processing, forming a threaded rib structure on the inner wall, which significantly increases the heat transfer area between the refrigerant and the copper tube. Compared to traditional smooth tubes, this structure doubles the heat exchange area, greatly improving overall heat transfer efficiency and refrigeration performance.

Finned Condenser

Air-cooled chillers use condensers with high-efficiency copper tubes paired with aluminum fins, significantly enhancing the system's heat dissipation capacity. The aluminum fins greatly increase the heat exchange surface area between the condenser and the air, thereby accelerating heat transfer and dissipation efficiency.

High-quality copper tubes have excellent thermal conductivity, and combined with the high-efficiency heat dissipation characteristics of aluminum fins, they ensure that the heat from the refrigerant can be quickly released during the condensation process, effectively improving overall cooling efficiency.

Additionally, the condenser surfaces use hydrophilic aluminum foil and blue-coated aluminum fins, which can effectively prevent condensation water from stagnating and offer certain corrosion resistance, thereby extending the condenser's service life and ensuring long-term stable operation of the system while consistently maintaining good cooling performance.
