The inner casing (2) of the packaging unit is fitted with barrier components (3) and refrigerating units (4). The freezing barrier components have an outer temp. pref. between 0 and 8 deg. celcius, and are positioned nearest to the space for the goods to be transported. The refrigeration units, with a lower temp. and higher refrigerating capacity, are positioned behind the freezing barrier components so that heat transmission from the latter to them is made possible. Direct contact between the goods and the refrigeration untis is prevented, however. |
