The main features of scroll refrigeration compressors include:
The pressure difference between the two adjacent chambers is small, and the gas leakage is small. This feature makes the volumetric efficiency of the scroll compressor very high, with a theoretical volumetric efficiency of up to 100%, and the measured value is also above 95%.
The torque variation amplitude is small and the vibration is small. Due to the smooth rotor movement of scroll compressors, the noise and vibration generated by them are relatively low, making them particularly suitable for applications that require low noise and vibration.
There is no clearance volume, so there is no expansion process that causes the gas transfer coefficient to decrease. This feature further increases the efficiency of scroll compressors.
No suction and exhaust valves, high efficiency, high reliability and low noise. The small gap between the rotor and stator of scroll compressors allows them to maintain high tightness and stability at high speeds, thus improving the efficiency and reliability of the compressor.
Due to the use of gas support mechanism, it is allowed to compress with liquid. This feature enables scroll compressors to maintain stable performance under certain special working conditions.
The inner cavity of the casing is an exhaust chamber, which reduces the suction preheating and improves the gas transmission coefficient of the compressor. This design makes the scroll compressor more efficient in operation.
The machining accuracy of the vortex body profile is very high, and special precision machining equipment must be used. This requirement makes scroll compressors relatively expensive to manufacture, but also guarantees their performance and quality.
The sealing requirements are high, and the sealing mechanism is complex. In order to ensure the efficient operation of scroll compressors, their sealing performance must be guaranteed, which also makes their structure relatively complex.
In summary, scroll refrigeration compressors have the characteristics of high efficiency, high reliability, low noise, low vibration, compact structure, small size, light weight and strong adaptability. These characteristics make scroll refrigeration compressors widely used in air conditioning, refrigeration and other fields.
