AI Technical Summary
In existing air conditioning systems, the vibration of the variable frequency compressor causes the pipes to vibrate. Existing vibration reduction methods are ineffective when the operating frequency of the variable frequency compressor changes, and the pipes are prone to detachment, thus failing to meet the vibration reduction requirements.
A damper system is adopted, which uses vibration-damping particles inside the pipe to dissipate energy through the collision between the particles and the shell, thereby achieving a wide-band vibration reduction effect. The system is installed at different locations on the pipe, including horizontal, vertical, inclined and bend locations, to enhance the strength of the bends.
It provides effective vibration reduction over a wide frequency range, adapts to the frequency changes of variable frequency compressors, the damper is not easy to fall off, and it can be installed in various locations on the pipeline without restriction, especially enhancing the strength at bends.
