Description

Pipeline vibration damper and air conditioning system Technical Field The utility model relates to the technical field of air conditioners, in particular to a pipeline vibration damper and an air conditioning system. Background In an air conditioning system, the refrigerant is subject to a series of fluid dynamics related vibration and noise problems during its cycle due to the phase change and flow rate changes. Particularly, when the refrigerant flows at a high speed or the pressure in the system is unstable, the natural frequency of the pipeline is easily excited, so that the resonance phenomenon is caused. The resonance not only can cause obvious pipeline vibration, but also can generate airflow noise such as high-frequency howling and the like, and the running stability of the system and the use experience of users are seriously affected. In view of the above problems, the prior art generally employs a rubber vibration damping method to perform vibration isolation treatment on a pipeline, so as to reduce the propagation of mechanical vibration generated by the operation of a compressor to the whole system. However, the rubber block has limited vibration isolation capability, so that the vibration reduction effect is poor, and the use experience of a user is further affected. Disclosure of utility model The utility model provides a pipeline vibration damper and an air conditioning system, which are used for solving the defect that the use experience of a user is affected due to poor vibration damping effect in a rubber block vibration damping mode in the prior art. The utility model provides a pipeline vibration damper, comprising: The first vibration reduction mechanism comprises a fixed ring and a first vibration reduction piece, wherein the first vibration reduction piece is arranged in the fixed ring and is provided with a mounting hole for mounting a pipeline; The second vibration reduction mechanism comprises a vibration reduction part, wherein the vibration reduction part is sleeved on the fixed ring and is used for absorbing vibration kinetic energy.
