Abstract
An air conditioner includes at least one compressor, an outlet pipe, an inlet pipe, and at least one bypass pipe. Oil and/or refrigerant discharged from the at least one compressor flows through the outlet pipe. The inlet pipe receives the oil and/or refrigerant flown through the outlet pipe and allows the oil and/or refrigerant to flow to the at least one compressor. The at least one bypass pipe is connected to the at least one compressor and allow bypass flows of the oil and/or refrigerant from the at least one compressor to the outlet pipe.
Claims21
An air conditioner comprising:
- at least one compressor;
- an outlet pipe through which oil and/or refrigerant discharged from the at least one compressor flows;
- an inlet pipe receiving the oil and/or refrigerant flown through the outlet pipe and allowing the oil and/or refrigerant to flow to the at least one compressor;
- and
- at least one bypass pipe connected to the at least one compressor and allowing bypass flows of the oil and/or refrigerant from the at least one compressor to the outlet pipe.
An air conditioner comprising:
- a plurality of compressors;
- a plurality of branch outlet pipes through which a fluid discharged from the compressors flows;
- pressure reduction parts respectively disposed at the branch outlet pipes to reduce a pressure of a fluid discharged from the compressors;
- and
- bypass pipes connected from the compressors to the pressure reduction parts to allow bypass flows of a fluid from the compressors to the branch outlet pipes.
An air conditioner comprising:
- a plurality of compressors;
- a plurality of branch outlet pipes connected to the compressors to receive flows of a fluid discharged from the compressors;
- at least one oil separator separating oil from the fluid flowing through the branch outlet pipe units;
- and
- a plurality of bypass pipes connected to the compressors to receive bypass flows of the fluid discharged from the compressors and communicated with an inlet or outlet of the oil separator.
