Abstract (en)
A refrigeration system (1) includes first to third compressors (11a, 11b, 11c) connected in parallel and an oil separator for separating a refrigeration oil from a refrigerant discharged from the compressors (11a, 11b, 11c). A main suction pipe (55) in which a refrigerant to be sucked into the compressors (11a, 11b, 11c) flows includes a primary curved portion (101) and a primary branch element (102) assembled to part of the main suction pipe (55) downstream of a junction with an oil return pipe (71) for returning the refrigeration oil separated by the oil separator. The main suction pipe (55) is branched by the primary branch element (102) into a first suction pipe branch (61a) of the first compressor (11a) and a connecting suction pipe (56). In the primary branch element (102), the first suction pipe branch (61a) is at the bottommost position and the outermost position in the direction of a radius of curvature of the primary curved portion (101).
