Compressor, a driven fluid machine that raises low pressure gas to high pressure. It is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby realizing Compression→condensation→expansion→evaporation (heat absorption) refrigeration cycle.

The role of the air compressor in the engine:

  1. The compressed air can push the brake cylinder and clutch cylinder to control the braking of the car.
  2. use the compressed air to realize the water spray function of the drip brake, so as to realize the cooling of the brake drum.
  3. The air compressor is the heart of the automotive air-conditioning system, which can transform the refrigerant from a gaseous state into a liquid state, thereby achieving the purpose of cooling and condensing the refrigerant.
  4. The turbine engine also uses the air compressor to compress the air and send it into the intake pipe to improve the combustion efficiency of gasoline or diesel in the turbine engine, thereby reducing fuel consumption and outputting greater power output.
