Abstract

See full text

A soundproof part that covers a compressor includes a side surface cover including two or more sound absorbing materials and two or more sound insulating materials, and configured to cover a side surface of the compressor. The two or more sound insulating materials include sound insulating materials having different specific gravities. The side surface cover is formed such that one sound absorbing material is disposed adjacent to the compressor, and a sound absorbing material and a sound insulating material are alternately arranged. The side surface cover is also formed such that as a distance from the compressor increases, the sound insulating materials having relatively lower specific gravities are disposed.
