A refrigerating apparatus (1) and a control method thereof which can rapidly detect the fact that no high pressure refrigerant is introduced into an oil equalizing tube (11) due to failure of an opening/closing value (13), etc., thereby being capable of preventing the flow of oil mist, and thus, preventing damage to compressors (3, 4). The refrigerating apparatus includes a plurality of compressors (3, 4) connected in parallel in a refrigerant circuit (2), an oil equalizing tube (11) adapted to connect shells of the compressors, a bypass tube (12) adapted to connect the oil equalizing tube to a discharge refrigerant line (8) of the compressors, and an opening/closing valve (13) arranged at an intermediate portion of the bypass tube. The bypass tube, which is positioned between the opening/closing valve and the oil equalizing tube, is provided with a temperature sensor (14) adapted to detect a temperature of the bypass tube itself or an internal temperature of the bypass tube. <IMAGE>
