The piston compressor and the screw compressor are collectively referred to as a positive displacement compressor, and the centrifugal compressor is driven by the high speed operation of the impeller to generate centrifugal force when the motor is running, so that the low pressure gaseous refrigerant is sucked from the side suction port. The centrifugal force generated by the high-speed rotation causes the gas to obtain great kinetic energy to flow out from the impeller, and the flow rate is reduced by the diffuser. As the section increases, the energy changes, and the gas obtains a larger pressure energy and the pressure rises. Until it is discharged.
Due to the high rotational speed of the compressor, the amount of exhaust gas is increased. Suitable for large refrigeration systems.
The centrifugal compressor has compact structure, large cooling capacity, light weight, stable operation, low noise, and no lubricating oil is mixed in the refrigerant during operation.
