ABSTRACT:
The invention relates to the design of a capsule for a hermetically encapsulated small refrigerator. The damping of noise is an important requirement and to this end it is conventional that the motor-compressor unit mounted in the capsule is resiliently mounted relative thereto. The radiation of noise generated in the capsule is thwarted by arranging opposite wall sections in nonparallel relationships so that a sound wave striking a wall section is prevented from being reflected to a parallel wall section which would be conducive to amplification by continuing reflection.
