Document Type and Number:
WIPO Patent Application WO/2019/130393
Kind Code:

Abstract:
Provided are a separator with improved oil separation efficiency and a refrigeration cycle apparatus provided with the separator. The separator is provided with: an intake pipe part (1); an oil retaining part (4); an oil return pipe part (3); and an outlet pipe part (2). The intake pipe part (1) includes a rotation section (5) that restricts the flow direction of the refrigerant so as to cause the refrigerant to rotate. The oil retaining part (4) is connected to the intake pipe part (1). The oil return pipe part (3) is connected to the bottom side of the oil retaining part (4) in the vertical direction. The outlet pipe part (2) includes an open end section (6) that faces the rotation section (5). The outlet pipe (2) extends from a region facing the rotation section (5) to the outside of the oil retaining part (4). The open end section (6) is configured such that refrigerant discharged from the rotation section (5) can flow directly into the open end section.
