Noise reduction in a two-cylinder rotary compressor.

Author(s) : WOO S., LEE U., SUNG C., et al.

Summary

The authors have developed two-cylinder rotary compressor with BLDC motor, hereafter referred to as TBR compressor, to address the growing concerns over the environment pollution and the energy efficiency. TBR compressor was designed to use R-410A refrigerant, so that the damage of ozone layer can be minimized. The concentrated winding BLDC motor was chosen to achieve high efficiency by reducing the power consumption. However, the noise was a big concern over the course of development. This study was designed to investigate the sources of the noise and how to reduce them. The major noise sources of TBR compressor are divided into 4 big categories, which are investigated by CAE simulation and experimental methods. The modifications are applied to reduce the sound pressure level of each noise source.
