Noise Reduction of Hermetic Refrigeration Compressors by Changes of Hermetic Shell Characteristics
نویسندگان
چکیده
A number of compressor design modifications to reduce the noise which are based on the modal characteristics of the compressor shell are discussed and special problems are pointed out. Most design changes exhibit effects across broad frequency regions and while reducing the noise in some frequency bands can cause noise increases in other bands. Shell damping was found to be a generally consistent means of reducing compressor noise and very effective when applied at the proper location. The shell deformation patterns of the running compressor proved to be an effective criterion for determining damping locations.
