Abstract: The main sources of refrigerator noise are mechanical room, fans, piping systems etc. The mechanical room includes a compressor, a rubber mat, a baseboard and suction pipes, which is the main source of mechanical noise in refrigerators. The design of the relevant parts of the mechanical room directly determines the noise performance of the refrigerator. Simulation optimization and experimental analysis are used in this paper to reduce the low frequency noise of the refrigerator as an example, which provided a solution to the problem of the resonance.

Key words: Refrigerator, Mechanical room, Compressor, Resonance, Simulation
