Abstract

The invention provides a compressor and an air conditioner. The compressor is applied to the air conditioner, the compressor comprises a shell, a first rotating shaft, a connecting assembly and a first rotor assembly, and the first rotating shaft is installed in the shell; the connecting assembly is arranged on the first rotating shaft in a sleeving manner; the first rotor assembly comprises a first rotor and a second rotor which are coaxially arranged on the connecting assembly, and the connecting assembly can bear the first rotor and the second rotor to rotate together around the first rotating shaft; and the connecting assembly is further configured to limit the relative positions of the first rotor and the second rotor, so that a gap is formed between the first rotor and the second rotor. According to the embodiment of the invention, the gap can be kept between the first rotor and the second rotor under the condition that the number of parts of the compressor is not increased.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor and an air conditioner. Background technique [0002] Usually, a pair of parallel helical rotors are arranged in the compressor, and the pair of helical rotors form a space volume with the inner wall of the casing. During the working process of the screw rotor, the volume will increase and decrease periodically. Through reasonable design, the volume is periodically connected and closed with the suction port and the exhaust port, so that the whole process of suction, compression and exhaust can be completed. At present, dual compressors are widely used in refrigeration and air conditioning in the medium cooling capacity range. [0003] During the working process of the screw rotor, the pressure of the gas at the suction port and the exhaust port is different, so that the screw rotor will generate an axial force, and the axial force will make the screw rotor move...
