PURPOSE: A device for preventing concentrating of oil of a compressor is provided to prevent oil from being concentrated in compressors by forming an oil balancing pipe and a flow change valve for balancing the compressors. CONSTITUTION: A device for preventing concentrating of oil of a compressor comprises multiple suction pipes(14,16), multiple discharging pipes(24,26), an oil balancing pipe(22), and a flow change part. The suction pipes branch off a refrigerant transferred through a transfer pipe(10). The discharging pipes discharges the inhaled refrigerant. The oil balancing pipe is connected between compressors, and moves oil in the compressors. The flow change part is connected between the discharging pipes and the transfer pipe, and prevents the oil in the oil balancing pipe from being concentrated in the compressors.
