Compressor-Hitachi 3p inverter compressor What are the characteristics of scroll refrigeration compressors? The characteristics of scroll refrigeration compressors are as follows, and their characteristics are also the goals that air-conditioning compressor manufacturing technology is constantly pursuing.
① The pressure difference between two adjacent chambers is small, and the amount of gas leakage is small. ② The torque change range is small and the vibration is small.
③ There is no clearance volume, so there is no expansion process that causes the gas transmission coefficient to decrease. ④ No suction and exhaust valve, high efficiency, high reliability and low noise. compressor
⑤ As the gas support mechanism is adopted, it is allowed to compress with liquid. ⑥ The inner cavity of the casing is an exhaust chamber, which reduces the suction preheating and improves the compressor's air transmission coefficient.
⑦. The machining accuracy of the vortex body line is very high, and special precision machining equipment must be used. ⑧ High sealing requirements and complicated sealing mechanism The compressor is an indispensable part of the refrigeration system. Now it has been widely used in air conditioners because of its reliable operation and high performance coefficient.
