An accumulator connected to a compressor, the accumulator including a case that forms a space in which liquid refrigerant and gaseous refrigerant are accommodated, a suction pipe which is connected to the case, and at least one connection pipe which connects a side surface of the case and a suction side of the compressor, whereby a space between a side surface of the compressor and a side surface of the accumulator is less than a length of a portion of the connection pipe from the side surface of the compressor to the side surface of the accumulator.

Accumulator

A rotary compressor includes: a shell defining an internal space; a driving motor arranged in the internal space of the shell; and a compression mechanism unit to receive power of the driving motor and compress refrigerant, wherein the compression mechanism unit includes: a cylinder defining a chamber in which the refrigerant is compressed; a rotary shaft connected to the driving motor; a roller located in the chamber and connected to the rotary shaft to compress the refrigerant in the chamber while being rotated; a bearing coupled to the cylinder and having a discharge port through which the refrigerant compressed in the chamber passes; a muffler coupled to the bearing and into which the refrigerant passing through the discharge port is introduced; and a noise reducing unit fixed to the muffler to define a noise reducing chamber together with the muffler.

Rotary compressor

An accumulator having a case which forms a space in which liquid refrigerant and gaseous refrigerant are accommodated, a suction pipe connected to a first side of the case, a connection pipe that connects a second side of the case to a suction side of the compressor, and a gas-liquid separation pipe disposed inside the case to guide the gaseous refrigerant to the connection pipe, and in which the gas-liquid separation pipe is disposed inside the case and is separated from the connection pipe.

A vapor-liquid separator includes a casing having an accommodation space, an inlet at the casing to allow a refrigerant mixture fluid to be intaken to the accommodation space therethrough, and an outlet at the side of the inlet to allow a gas phase refrigerant separated from the refrigerant mixture fluid to be discharged therethrough.
