Abstract: There are many kinds of abnormal sound pressure in the indoor unit, among which the problem of transmitting sound is one of the difficult problems to solve. The problem of sound transmission can be effectively solved by adding a resistant silencer in the outdoor unit, but the selection of the location of the silencer plays a vital role in solving the problem. According to the structure of different compressors, the root cause of sound transmission and propagation path are analyzed in detail, through theoretical analysis and experimental verification, the solutions of different compressor air conditioners in different models of sound transmission are obtained, which provide reference for the subsequent rapid solution to the sound transmission problem.
