Problems solved by technology

[0008] To sum up, it can be seen that in the prior art, the airflow energy is mostly passively reduced to achieve the shock absorption effect or the natural frequency of the relevant pipeline and the gas column are adjusted to avoid the resonance frequency region. There is no device in the prior art that is Actively attenuate the airflow pulsation of the compressor from the source, thereby reducing the impact of noise and vibration

Abstract

The invention provides a noise reduction device, a compressor and an air conditioner. The noise reduction device is arranged at an exhaust port of the compressor; the noise reduction device comprisesa main flow pipeline, one or more side branch pipelines, wherein along the flowing direction of air flow, the outlet end of the main flow pipeline communicates with the outlet end of each side branchpipeline; a waveform of air flow flowing through the main flow pipeline and a waveform of air flow flowing through the at least one side branch pipeline have a phase difference so as to reduce an amplitude value of a waveform of converged air flow. The noise reduction device disclosed by the invention can actively attenuate the pulse of the air flow so as to reduce noise.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a noise reduction device, a compressor and an air conditioner. Background technique [0002] The vibration and noise of the refrigeration unit is an important factor affecting the reliability and user experience of the unit. At present, the main vibration causes are divided into two parts: one is that the mechanical vibration of the compressor body is transmitted to the unit. Due to the poor dynamic balance of the moving parts of the compressor itself, misalignment, improper foundation design, etc., it can cause the vibration of the unit, thereby causing the pipeline connected to it to vibrate; on the other hand, the exhaust gas of the compressor is in the pipeline Create air pulsation. If the compressor produces pressure changes during the exhaust process or due to the intermittent and periodic suction and exhaust of the unit during operation, these conditions will ar...
