RESONATOR DEVICE INSTALLED IN CASE OF REFRIGERATING UNIT Russian patent published in 2011 - IPC F25D21/14

Abstract RU 2415354 C1

FIELD: machine building.

SUBSTANCE: case forms compartment comprising compressor. The case consists of a pressure tight jacket and also an evaporating pan for defrosted water. The pan has a bottom wall designed for installation on an upper part of the jacket and periphery wall projecting on top from the bottom wall, At least one of periphery walls and the bottom wall of the evaporating pan bear a sound absorbing device turned in the direction of the noise generating zone of the said compartment. It is made with dimensions determining certain reactive impedance and certain impedance of absorption in medium of the compartment for a specified frequency range.

EFFECT: resonator deice efficiently damping noise generated with compressor and fan in wide frequency band without change of dimensions and thickness of compressor jacket.
