Problems solved by technology

[0002] At present, due to the comfort requirements of the inverter air conditioner, the operating frequency range is very wide, and the pipeline between the compressor and the condenser has a certain difference in the natural frequency of the pipeline due to the difference in material and processing technology during the processing process. When the compressor When the operating frequency of the pipe overlaps with the natural frequency of the pipe, resonance will occur, which will lead to pipe cracking
[0003] In the existing treatment methods, the reinforcement of the pipeline is basically the main method, the anti-vibration performance of the pipeline itself can be changed, and some anti-resonance devices can also be added, but the effect of these changes is not ideal, and it will inevitably bring cost increase

Embodiment 1

[0048]A US-KFR26GW / BP3N1Y-9A1(C4) split-type inverter air conditioner originally operated at 20HZ, the amplitude TS of the pipeline was 800μm, and there was resonance during operation, and 10 appeared after two months of operation. % or so leakage. Install the air conditioner pipeline vibration control system of the present invention on the air conditioner, and use the air conditioner pipeline vibration control method of the present invention to adjust and control. When the operation reaches 20HZ, it is detected that the amplitude value TS>450μm, and then the frequency of the compressor F is increased by 10HZ, and then the value TS is detected every 10~1000S, and according to the corresponding compressor frequency F, it is continuously adjusted according to the above method, so that the fatigue life of the pipeline can reach more than 6 years, excluding other The interference of factors on the vibration frequency can effectively control the vibration of the pipeline within a c...

Abstract

The invention relates to an air conditioning line vibration control system and method. A vibration sensor used for monitoring vibrational amplitude of a line is disposed on the line between a compressor of an air conditioner and a condenser thereof, a value of the vibrational amplitude of the line is transmitted to an outdoor unit master control panel, and the outdoor unit master control panel adjusts running frequency of the compressor according to the value of the vibrational amplitude. The value of the vibrational amplitude of the line is monitored to control the running frequency of the compressor, the system monitors vibration of the line in real time and auto-adjusts the running frequency of the compressor according to pre-set rules, the influence of other factors upon vibrational frequency is eliminated, the vibration of the line can be effectively controlled in a certain range, effective control of line vibration is achieved, and system reliability is improved.

Description

technical field [0001] The invention relates to a vibration control system and method for an air-conditioning pipeline, which belongs to the field of air conditioners, in particular to the field of split frequency conversion air conditioners. Background technique [0002] At present, due to the comfort requirements of the inverter air conditioner, the operating frequency range is very wide, and the pipeline between the compressor and the condenser has a certain difference in the natural frequency of the pipeline due to the difference in material and processing technology during the processing process. When the compressor When the operating frequency of the pipe overlaps with the natural frequency of the pipeline, resonance will occur, which will cause the pipe to crack. [0003] In the existing treatment methods, the reinforcement of the pipeline is basically the main method, the anti-vibration performance of the pipeline itself can be changed, and some anti-resonance device...
