Hitachi 101 cold storage compressor The role of the compressor in the air conditioning system
From the current development trend of refrigeration compressors, in order to make it compact, efficient, energy-saving and low-vibration and low-noise, it has become the goal that air-conditioning compressors continue to pursue in manufacturing technology. Its role is mainly manifested in the following points: compressor
(1) The compressor absorbs steam from the evaporator to ensure a certain evaporation pressure in the evaporator; ⑵ Compressor increases pressure (compression), used to create conditions for condensation at higher temperatures; ⑶The compressor can deliver refrigerant, and then make the refrigerant complete the refrigeration cycle 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 the two adjacent chambers is small, and the 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, Hitachi 5P cold storage compressor, high reliability and low noise. compressor ⑤ As the gas support mechanism is adopted, it is allowed to be compressed with liquid. ⑥ The inner cavity of the casing is the exhaust chamber and the compressor, which reduces the suction preheating. The Hitachi cold storage compressor 5p improves the compressor's air transmission coefficient. ⑦. The machining accuracy of the spiral body profile is very high. Hitachi 101 cold storage compressors must use special precision processing equipment. ⑧ High sealing requirements and complicated sealing mechanism
The compressor is an indispensable part of the refrigeration system, and now it has been widely used in air conditioners because of its reliable operation and high coefficient of performance.
Two scrolls of compressor and their functions The compressors commonly used in refrigeration systems have two scrolls, one is a moving scroll and the other is a static scroll. The center of the movable scroll in the compressor makes a circular motion around the center of the fixed scroll in the compressor under the drive of the main shaft. This movement will cause compression between the two scrolls, and then the low-pressure gas enters the suction chamber, and the compressor The compression of the moving scroll is a continuous process. In the second circular motion, part of the gas is compressed, the other part of the gas enters the scroll, and part of the gas is discharged. Therefore, the compression of the scroll compressor is completed by the two scrolls located above the compressor, and the scroll is located above the motor.
