The invention provides a scroll compressor and an air conditioning system. The scroll compressor comprises a machine shell, a compression mechanism part, a main machine frame, a motor, a crankshaft, a main balance block and an exhaust pipe. In the radial direction of the machine shell, the depth of the exhaust pipe extending into the machine shell is W, the distance between the outer circle of the main balance block and the inner wall of the machine shell is L, and W / L is larger than or equal to 0.47 and smaller than or equal to 0.93, so that one part of high-pressure oil-gas mixture exhausted by the compression mechanism part enters the exhaust pipe to be exhausted after cyclone separation of rotation of the main balance block and mechanical separation of the machine shell. And the other part of the gas enters axial channels such as a gap between the stator and the rotor, oil-gas separation is realized while the motor is cooled, and then the gas is exhausted through the exhaust pipe, so that the gas entering the exhaust pipe is subjected to more sufficient oil-gas separation, the oil circulation rate is reduced, the reliability of the scroll compressor is improved, and the service life of the scroll compressor is prolonged. And the reliability and the efficiency of an air conditioning system using the scroll compressor are improved.
Description
technical field [0001] The present application belongs to the technical field of compressors, and more specifically relates to a scroll compressor and an air conditioning system. Background technique [0002] When the scroll compressor is working, the mixture of refrigerant and oil entering from the suction pipe is compressed by the compressor chamber formed by the cooperation of the fixed scroll and the movable scroll to become a high-pressure oil-gas mixture. At present, the exhaust pipes of the scroll compressors are all arranged on the casing between the main frame and the stator, which causes a part of the above-mentioned high-pressure oil-gas mixture to be discharged from the compressor without effective oil-gas separation; the other part of the above-mentioned high-pressure oil-gas mixture is in the After entering the cavity between the main frame and the stator, it is not effectively separated from the casing wall for a second time and discharged from the compressor,...
