Abstract: Transmitting sound is a typical noise in the abnormal noises of indoor unit. If the noise is caused by the structural vibration of the pipe, in addition to the method of installing the muffler on the pipe, the method of avoiding resonance can also be used to deal with it. Aiming at the transmitting sound problem of the indoor unit of air conditioner, avoid resonance between compressor and pipes by changing the structure of the latter. The transmitting sound of indoor unit is eliminated, the purpose of rectification has been achieved. It provides an effective method for the solution to the problem of transmitting sound in the indoor unit.
