ABSTRACT:
A refrigerator which includes cooling chamber including a refrigerating chamber and a freezing chamber, an axial flow fan for circulating air within the cooling chamber, a heat exchanger for cooling the air circulated by the axial flow fan, a suction side space so formed as to guide the air cooled by the heat exchanger from the heat-exchanger to the axial flow fan, and a sound absorbing material for absorbing noises produced in the suction side space and the cooling chamber so as not to leak outside the refrigerator, with the suction side space and the cooling chamber respectively having resonance dimensions for resonation at specific frequency regions. The suction side space is set, in its resonance dimension, to the frequency region at which the sound absorbing material can absorb the sound in an efficient manner.
