[0091] The difference between the second embodiment and the first embodiment is at least that: the fourth pipe segment 24 in the first embodiment is set as a hose, which has a better vibration damping effect compared to the first embodiment. Moreover, the length of the first pipe section 21 of the exhaust pipe 2 in the second embodiment is the same as that of the first pipe section 21 in the first embodiment, which reduces the rigidity of the exhaust pipe 2 .

Abstract

The invention relates to a compressor system and an air-conditioner. The compressor system comprises a compressor and an exhausting pipe. The compressor comprises a first end and a second end in the length direction. The compressor is provided with an exhausting opening. The exhausting opening is located between the first end and the second end and is close to the first end. The exhausting pipe comprises a first pipe section. The first end of the first pipe section is connected with the exhausting opening. The second end of the first pipe section extends to the second end of the compressor inthe length direction of the compressor. The length range of the first pipe section is between 65 mm and 70 mm. Compared with the related technology, the length of the first pipe section is increased,and on one hand, vibration of the compressor in the vertical direction is balanced; on the other hand, torsional vibration in the rotating direction due to steam pulse of compressed refrigerant is improved, and thus the exhausting pipe can work stably in the operation process. The rigidity of the exhausting pipe is reduced, pipeline vibration and surface stress are reduced, and noise generated byvibration is reduced.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor system and an air conditioner. Background technique [0002] The sliding friction loss of the twin-cylinder rotor compressor is relatively large when it is running at low frequency, but when it is running at high frequency, the deformation of the shaft due to unbalanced mass and gas pressure is small, so compared with the single-cylinder rotor compressor, it has Good dynamic balance characteristics, small friction loss and high mechanical efficiency. [0003] The horizontal twin-cylinder rotor compressor has the problem of high vibration and noise, which leads to a corresponding increase in the vibration of the pipeline system, thereby increasing the stress of the pipeline. There are two factors causing the vibration of the horizontal twin-cylinder rotor compressor: one is the vibration in the vertical direction of the shell caused by the unbalanced mass of the rotor syst...
