In volume type refrigeration compressor, the gas pressure by variable displacement to improve, be forced to shrink type refrigeration unit volume that are widely used in the compressor with reciprocating piston compressor, screw compressor, rotary compressor and rolling rotor compressor.
1, the reciprocating piston compressor is divided into two kinds of connecting rod type and the swashplate.
Mainly used in refrigeration, air conditioning, heat pump, cold storage, vehicle air conditioning, etc.
Connecting rod type with models, easy production, low price, capacity and so on characteristics.
Swash plate has characteristics such as high speed, small capacity.
2, rotary compressor is divided into the single screw and twin screw, the vortex type, the rolling rotor type, sliding-vane, etc.
Single/double screw compressor pressure ratio, alternative large reciprocating compressor.
Vortex type/rolling rotor type/sliding vane compressor has characteristics such as high speed, small capacity.
