[0002] The compressor is a driven fluid machine that can boost low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).

[0003] Application No. 202320304595.4 discloses a permanent magnet variable frequency screw air compressor, which relates to the technical field of air compressors, including a box, wherein the air compressor body, a permanent magnet motor, an oil-gas separator and an installation box are fixedly installed inside the box, and an adjustment mechanism and a wire harness mechanism are arranged inside the installation box, and a variable frequency controller is fixedly installed on the adjustment mechanism. By setting the variable frequency controller, the output gas volume of the compressor is controlled by the variable frequency control technology, so that it changes with the change of the motor speed, so that the air compressor is more energy-efficient than an ordinary screw machine.
