Scroll Compressor

The entire series of Dingyuan air-cooled chillers is equipped with high-performance scroll compressors as standard. As the core component of the entire refrigeration cycle system, the scroll compressor offers excellent stability and reliability.

This compressor features an advanced 'dual flexible design,' allowing automatic adjustment in both axial and radial directions, effectively ensuring the sealing between the scroll plates. This structural design permits small debris or liquid refrigerant to pass through during compression without damaging the compressor, significantly enhancing its resistance to liquid slugging and impurities.

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 highly efficient seamless copper heat exchange tubes, which are precisely processed using the 'Yuhua' technique, forming a threaded rib structure on the inner wall. This 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.
