<P>PROBLEM TO BE SOLVED: To resolve a problem when using a configuration of a large capacity refrigerator in a form of connecting a plurality of outdoor units in parallel with each other wherein dispersion is caused in distribution of oil just by simply connecting the outdoor units, oil gradually decreases in an outdoor unit with a small distribution amount of oil, eventually oil dries up, and a compressor of the outdoor unit breaks. Ž<P>SOLUTION: In the refrigeration system, a refrigerating cycle is formed by connecting a plurality of outdoor units 2a, 2b equipped with at least compressors 3a, 3b, condensers 5a, 5b, and accumulators 6a, 6b, and an indoor unit 20 equipped with a pressure reducing means 21 and an evaporator 22 in parallel with each other by piping. It is equipped with oil return pipes 9a, 9b returning refrigerating machine oil stored in the accumulators 6a, 6b to the compressors 3a, 3b, and an oil equalizing pipe 11 connecting each oil return pipe 9a, 9b.
