Compressor (compressor), the low-pressure gas upgraded to a high-pressure gas driven fluid machinery. Is the heart of the cooling system that draws in refrigerant gas from the suction pipe of the low temperature and pressure, the piston to compress, the exhaust pipe temperature high-pressure refrigerant gas through the motor drive operation to provide power for the refrigeration cycle, in order to achieve compression → condensation (heat) → expansion → evaporation (heat absorption) of the refrigeration cycle.
Compressor of piston compressors, screw compressors, centrifugal compressors. Piston compressors generally the case, motors, cylinders, pistons, control equipment (starters and thermal protection) and cooling system. Cooling cold and cooling two natural oils.
Single-phase AC electric compressor is general household refrigerators and air conditioners as a power source, their structure is basically the same principle. Both use different refrigerants.

Compressors are pipelined production. In the machine shop (including casting) to create a cylinder, a piston (shaft), valves, connecting rods, crankshaft, end caps and other parts; motor workshop assembled rotor, stator; at the stamping plant manufactured housing and so on. Then in the final assembly plant for assembly, welding, cleaning and drying, and finally passed the test packaging factory.
Air compressor parts are the following: cylinder | cylinder head, crosshead, coolers, gas cutting | cutting slices, crankshaft, connecting rod, head W | bulk tile, rod, seals, oil scraper ring, bearing ring and so on.

Automotive air conditioning compressor is the heart of automotive air conditioning and refrigeration systems, compression and transport plays a role in the refrigerant vapor.
Compressor points: two immutable displacement and variable displacement.
Air conditioning compressor inner workings of different compressor can generally be divided into reciprocating and rotary, reciprocating compressors have a common crankshaft and connecting rod axial piston, rotary common rotary vane compressors and scroll.
