PURPOSE: An air conditioning device is provided to simplify the structure of the device by allowing oil to always enter into a compressor always powered. CONSTITUTION: An air conditioning device comprises multiple compressors(120a,120b,120c), oil transfer pipes(114a,114b,114c), oil flow valves(135a,135b,135c), and capillary pipes(137a,137b,137c). The compressors compress refrigerants when the device is powered. The oil transfer pipes are connected to the compressors and send oil to the compressors. The oil flow valves are arranged on the oil transfer pipes and control the flow of the oil. The capillary pipes are arranged on the oil transfer pipes and lower the pressure of the oil. |
