摘要

And a carbon dioxide receiving portion 28 separated (57) due to adiabatic partition member 32 and the [summary] cargo receiving portion 25, place the solid carbon dioxide a predetermined amount of carbon dioxide in the receiving portion 28 at the beginning of the period, within a predetermined range Stackable and aspect in close contact with each other to maintain the frozen cargo without replenishing the solid carbon dioxide a very long time by the insulated properly partitioning member to provide a heat transfer coefficient, and and / or vertically the top of each other system to maximize such periods by using the enclosure of the cargo carrying container forms a substantially rectangular shape, to maintain the frozen condition of the cargo for an extended period of time.
