Abstract

The invention discloses a vibration protection method and a vibration protection device of a pipeline of an air conditioning compressor, which belong to the technical field of air conditioners. The method comprises the steps of obtaining vibration data of the air conditioning compressor during operation; determining the amplitude and strain capacity of a refrigerant pipeline which is in vibration transfer relation with the compressor according to the vibration data; and controlling the compressor to change frequency when the amplitude and strain capacity satisfy preset vibration conditions. According to the vibration protection method of the pipeline of the air conditioning compressor, the vibration data of the compressor during operation are detected, so that whether the amplitude and strain of the related refrigerant pipeline are within a reasonable range can be analyzed and judged, and thus, if the amplitude and strain of the related refrigerant pipeline are not within the reasonable range, resonance points which possibly result in breaking of welding spots of the pipeline can be avoided by performing frequency conversion treatment on the air conditioning compressor, so that the reliability of the air conditioning refrigerant pipeline is guaranteed, and potential safety hazards caused by refrigerant leakage are reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for protecting the pipeline vibration of an air conditioner compressor. Background technique [0002] During the operation of the existing air conditioner, due to the vibration of the compressor, the pipeline connected to the compressor will vibrate synchronously. During the long-term operation, it may cause the welding point of the pipeline to vibrate and crack, which will lead to refrigerant leakage. ; Especially for air conditioners using flammable refrigerants, there may be a potential fire hazard. [0003] For the problem of pipeline vibration, there are two conventional solutions: 1. By adding cement or rubber blocks to the pipeline, changing the counterweight of the pipeline, thereby changing the resonance point, and adjusting the resonance point to the operating frequency of the press 2. By changing the direction of the pipeline, or lengtheni...
