Abstract
A scroll compressor of an air conditioner includes a refrigerant discharge tube through which refrigerant discharged to an inner space of a casing is discharged into a refrigeration cycle. The scroll compressor further including a venturi tube disposed adjacent to the refrigerant discharge tube in the inner space of the casing, and a liquid refrigerant discharge tube having a first end connected to the venturi tube and a second end opposite to the first end and communicating with the inner space of the casing at a lower side of the refrigerant discharge tube, where liquid refrigerant can be suppressed from excessively stagnating in the inner space of the casing.
Claims12
A scroll compressor, comprising:
- a casing that defines an inner space therein;
- a rotating shaft disposed in the inner space of the casing;
- a motor disposed in the inner space of the casing and configured to rotate the rotating shaft;
- a compression unit that is disposed in the inner space of the casing at one side of the motor and configured to compress refrigerant based on rotation of the rotating shaft, the compression unit having a discharge passage configured to discharge the refrigerant compressed by the compression unit to the inner space of the casing;
- a refrigerant discharge tube that has a first end connected to the inner space of the casing and a second end connected to a refrigeration cycle system, the refrigerant discharge tube being configured to discharge the refrigerant from the inner space of the casing to the refrigeration cycle system;
- a venturi tube disposed in the inner space of the casing adjacent to the refrigerant discharge tube, the venturi tube having a plurality of diameters;
- and
- a liquid refrigerant discharge tube that has a first end connected to the venturi tube and a second end in fluid communication with the inner space of the casing, the second end of the liquid refrigerant discharge tube being disposed below the refrigerant discharge tube.
