Abstract (en)
A gas refrigerant separatar-cum-refrigerant flow divider (DR) includes an inlet chamber (10) having a circular cross section, a speed increasing chamber (20) having a circular cross section, and an outlet chamber (30) having a circular cross section, which are coaxially arranged in series. The outlet chamber (30) introduces refrigerant from a refrigerant inlet port (14) and guides and swirls the refrigerant along an inner wall surface of the outlet chamber (30). The speed increasing chamber (20) increases the speed of a swirling refrigerant flow sent from the inlet chamber (10) and jets the swirling refrigerant flow into the outlet chamber (30) through a communication port (21), which is formed at the distal end of the speed increasing chamber (20). The diameter of the outlet chamber (30) is greater than the diameter of the communication port (21) at the distal end of the speed increasing chamber (20). The gas refrigerant separator-cum-refrigerant flow divider (DR) has a gas refrigerant extracting pipe (Pg) for extracting gas refrigerant from an axial portion of the swirling refrigerant flow and a refrigerant outlet pipe (Pd) for directing the refrigerant to the exterior after extraction of the gas refrigerant.
