The difference between two lines and one line of automobile air conditioning compressor
The two line may be electronic, will change its own line, the basic physical type
One line is a variable displacement compressor, and the two lines are compressors with an electromagnetic clutch
1, a line is a variable exhaust compressor, and the two lines are the compressor with electromagnetic clutch.2, compressor points: non variable displacement and variable displacement of two kinds.1) according to the principle of operation, the air conditioning compressor can be divided into constant displacement compressor and variable displacement compressor.2) according to the different work style, the compressor can generally be divided into reciprocating and rotary reciprocating compressor, a common crankshaft connecting rod and axial piston type rotary compressor, a common type of vortex and rotary vane.(1) the crankshaft connecting rod compressor is called the first generation compressor. The working process of the compressor can be divided into 4 parts, that is, compression, exhaust, expansion and suction, the cost is relatively low.(2) axial piston compressor can be called "second generation compressor". The common type is swing plate or swash plate compressor, which is the mainstream product of automobile air conditioning compressor.(3) the cylinder shape of rotary vane compressor has 2 kinds: round and oval. The rotary vane compressor requires high machining accuracy and high manufacturing cost.(4) scroll compressor is called the fourth generation compressor. Mainly divided into dynamic and double revolution type of 2. It has many advantages, such as compact structure, high efficiency, energy saving, micro vibration, low noise and reliability. It has been used more and more widely in the field of small refrigeration, and has become one of the main directions of compressor technology development.
