<P>PROBLEM TO BE SOLVED: To perform appropriate refrigerant injection to each compressor using an injection circuit in a refrigerating device having the plurality of compressors. Ž<P>SOLUTION: The refrigerating device is provided with the injection circuit (40) comprising first injection piping (37) branched from the first refrigerant piping (32) of a refrigerant circuit (10) and branched injection piping (37a, 37b, 37c) each further branched from the first injection piping (37). A supercooling pressure reducing valve (29) is installed in the first injection piping (37), and flow rate regulating valves (30a, 30b, 30c) are installed in the branched injection piping (37a, 37b, 37c), respectively.
