Abstract

This refrigeration system (1) comprises a circuit (2) through which there circulates a refrigerant fluid notably comprising a compression device (6) comprising first and second compressors (7, 8), each compressor comprising a body (9) comprising, on the one hand, a low-pressure part (11) containing a motor (12) and an oil pan (13) and, on the other hand, a refrigerant fluid intake orifice (15) opening into the low-pressure part, first and second branch pipes (21, 22) placing a refrigerant fluid distribution pipe respectively in communication with the intake orifices (15) of the compressors (7, 8), an oil level equalizing pipe (23) placing the oil pans (13) of the compressors in communication with each other, and a pressure equalizing pipe (24) placing the low-pressure parts (11) of the compressors in communication with each other. The first branch pipe comprises means for reducing the bore section for the flow of the refrigerant gas along said branch pipe.
