A refrigeration system for a refrigerated compartment, the temperature of which shall be kept as close as possible to a predetermined temperature, and comprising means (K, 1) to generate a cooled gas flow with a temperature essentially below said predetermined temperature. Furthermore, there is a sealed container element (3) filled with a substance, the freezing/melting temperature of which coincides substantially with said predetermined temperature and which solidifies and melts, respectiely, during change of volume. The container element is arranged between the refrigerated compartment and the flow canal (5; 9) for the cooled gas flow, in such a way that one side of the container element constitutes a limiting wall for said compartment and the other side constitutes a limiting wall for said flow canal. The container element (3) comprises an elastic deformable section (3a; 11; 18; 20), the position of which changes depending on volume changes of the liquid in the container element and the position of which brings about an increasing throttling of said flow canal (5; 9) for the cooled air flow with increasing proportions of solidified substance in the container element. |
