Hitachi ultra-low temperature heat pump 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 the two adjacent chambers is small, and the Hitachi ri32 inverter compressor has less gas leakage. 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 inverter 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 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 processing equipment must be used. 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. Does the compressor not start related to the four-way valve? There is no relationship between the compressor does not start and the four-way valve. Therefore, when the four-way valve coil is damaged, it will not cause the air-conditioning compressor to fail to start normally, nor will the compressor start normally after the good four-way valve coil is replaced. compressor When the compressor does not start, it is recommended to first check and confirm the resistance value of the air conditioning compressor winding and the state of the compressor starter, and then check whether there are obvious abnormal conditions in the main electrical control components of the air conditioner. Don't worry about the four-way valve again. Rotary compressor and multiple compressor
Compressors can be divided into rotary compressors and compound compressors. Hitachi ultra-low temperature heat pump compressors. In general, the structure of rotary compressors is much simpler than that of compound compressors, because there are fewer parts in rotary compressors. Therefore, the small size, light weight, and compressor are very beneficial to the miniaturization of the refrigeration system. In addition, because the motor of the compressor is also directly fixed to the compressor casing, the tangential vibration caused by the torque change during the operation of the rotary compressor is not easy to eliminate, but the air conditioning and refrigeration The system pipeline is to take effective vibration reduction measures to ensure the smooth, safe and low-noise operation of the air conditioner system. The double-cylinder rotary compressor in the rotary compressor can effectively solve the vibration condition of the rotary compressor.
