Abstract (en)

An injection pipe (17) that supplies a compressor (3) with a gas refrigerant subjected to gas/liquid separation by a receiver, which separates the reduced-pressure refrigerant into gas and liquid, or a gas refrigerant gasified by a heat exchanger, wherein a muffler (19) having an inside diameter larger than the inside diameter of the injection pipe (17) is provided at an end located at the compressor (3) side. This can reduce pulsation caused by a refrigerant flowing back from the compressor, which can reduce vibration and noise due to the pulsation, thereby preventing the pipe from being damaged by the vibration.
