Abstract

The sound quality and noise level of the compressor are obviously affected by balance of the crank-shaft system. An intermittent abnormal noise problem on a customer air-conditioner was detected through the crank-shaft displacement test, it is caused by the radial and longitudinal unbalance of the crank-shaft system of the rotary compressor. The test shows that the abnormal noise develops with the radial and longitudinal run-out of the crank-shaft of the compressor, the forces of the crank-shaft system are studied by the mechanical model and the optimization design schemes are obtained to solve the noise problem.
