Scroll compressor and refrigeration apparatus including the same

A scroll compressor comprising:

• a cylindrical casing having a cylindrical shape and including an internal space in which a lubricating oil exists;
• a partitioning member fixed to the casing and dividing the internal space into a first space and a second space;
• a compression element including a fixed scroll, a movable scroll movable relative to the fixed scroll, and a discharge hole that faces the first space;
• a first flow path provided in the partitioning member, connecting the first space and the second space, and having a dimension of 2 mm or more in a radial direction of the partitioning member;
• and
• a second flow path provided in the partitioning member so as to be apart from the first flow path, the second flow path
• connecting the first space and the second space, and
• including a narrow portion having a smallest flow path area,
• a ratio of a hydraulic diameter of the narrow portion to a length of the narrow portion in an axial direction of the casing being 0.01 to 0.07.
