Abstract
A compressor includes a bore, a rotor disposed within the bore, a compressor inlet, a compressor outlet and a compression chamber defined between the bore and the rotor. A volume of the compression chamber gradually reduces from the compressor inlet to the compressor outlet. An economizer is configured to fluidically connect to the compression chamber. The economizer is configured to inject a working fluid into the compression chamber at an injection position. The injection position is changeable according to a working condition of the compressor.
Claims15
A single compressor, comprising:
- a bore;
- a rotor disposed within the bore;
- a shaft supporting the rotor, the shaft extending in an axial direction;
- a compressor inlet;
- a compressor outlet;
- a compression chamber defined between the bore and the rotor, wherein a working fluid in the compression chamber is compressed and flows from the compressor inlet to the compressor outlet;
- and
- an injection port having a variable injection position along the axial direction,
- wherein the variable injection position is changed through controlling at least one flow regulator.
