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.
Claims17
An air conditioner comprising:
- a plurality of compressors, each compressor having an oil storage;
- an outlet pipe through which oil and/or refrigerant discharged from the plurality of compressors flows, the outlet pipe comprising a common outlet pipe and branch outlet pipes respectively connected to the plurality of compressors, and the common outlet pipe receiving flows of oil and/or refrigerant from the branch outlet pipes;
- 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 plurality of compressors, the inlet pipe comprising a common inlet pipe through which refrigerant discharged from an evaporator flows, and branch inlet pipes branching off from the common inlet pipe and respectively connected to the plurality of compressors;
- a plurality of bypass pipes connected to the plurality of compressors and allowing bypass flows of the oil and/or refrigerant from the plurality of compressors to the outlet pipe, the plurality of bypass pipes respectively directly connected to the plurality of compressors and the outlet pipe, the oil stored in the oil storage of each compressor being capable of discharging to the respective bypass pipe based on a position connected to the compressor,
- wherein the oil and/or refrigerant is discharged from the compressors to the branch outlet pipes directly are combined with the oil and/or refrigerant discharged from the compressors through the bypass pipes;
- and
- at least one oil separator separating oil from oil and refrigerant flowing through the outlet pipe, wherein the inlet pipe receives the oil separated by the oil separator and allowing the oil to flow to the plurality of compressors via the respective branch inlet pipes.

An air conditioner comprising:
- a plurality of compressors, each compressor having a storage;
- a plurality of branch outlet pipes through which a fluid discharged from the compressors flows, the plurality of branch outlet pipes being directly connected to the plurality of compressors;
- pressure reduction parts respectively disposed at the branch outlet pipes to reduce a pressure of the fluid flowing through the plurality of branch outlet pipes;
- bypass pipes directly connected from the compressors to the pressure reduction parts to allow bypass flows of a fluid from the compressors to the branch outlet pipes, the fluid stored in the storage of each compressor being capable of discharging to respective bypass pipe based on a position connected to the compressor,
- wherein the fluid is discharged from the compressors to the branch outlet pipes directly, and/or the fluid is discharged from the compressors to the branch outlet pipes through the bypass pipes;
- and
- an inlet pipe receiving the fluid flow through the branch outlet pipes, the inlet pipe comprising a common inlet pipe and branch inlet pipes branching off from the common inlet pipe and respectively connected to the plurality of compressors, though which the fluid flows to the plurality of compressors through respective branch inlet pipes.
