The spiral water-cooled chiller utilizes a spiral compressor, which is formed by two double-function equation-type dynamic and static spiral vanes interlocking together. During the suction, compression, and exhaust processes, the static disc is fixed on the frame, while the dynamic disc is driven by an eccentric shaft and restricted by an anti-rotation mechanism. It rotates around the center of the static disc's base circle with a very small radius. The gas is吸入 through the air filter core into the outer periphery of the static disc, and as the eccentric shaft rotates, the gas is progressively compressed in the crescent-shaped compression cavities formed by the mating of the static and dynamic discs. It is then continuously discharged through the axial holes of the static disc's central component. The unique design of the spiral compressor makes it a highly energy-efficient compressor in today's world. The main operating parts of the spiral compressor, the spiral vanes, have no wear and only fit together, thus extending their lifespan and earning the title of "maintenance-free compressor." The spiral compressor operates smoothly with minimal vibration and a quiet working environment, and is also known as the "ultra-quiet compressor." The spiral compressor's structure is innovative and precise, featuring small size, low noise, light weight, minimal vibration, low energy consumption, long lifespan, continuous and stable gas flow, reliable operation, and clean gas source. It is hailed as the "new revolution compressor" and "maintenance-free compressor," serving as an ideal power source for pneumatic machinery and widely used in industries such as industrial, agricultural, transportation, food packaging, and textile, as well as other applications requiring refrigeration and constant temperature.
