ABSTRACT:
A self contained refrigerated shipping or storage container utilizing liquid carbon dioxide is disclosed. The container utilizes a network of liquid containing units arranged to allow maximum useful storage space with maximum cooling. The container is insulated and has four walls, at least one of which has at least one access door therein, a floor and a roof, with a pressurized liquid carbon dioxide reservoir having a workable heat exchange relationship with the interior of the container. The reservoir includes a gaseous space with a vent from the space having a pressure relief valve therein adapted to maintain a substantially constant pressure in the reservoir such that the temperature of the liquid carbon dioxide in the reservoir is controlled. The improvement wherein the liquid carbon dioxide reservoir comprises a network of linked liquid containing units with horizontal units in the floor of the container connected to at least one vertical riser unit in at least one wall of the container, the vertical riser unit being connected to vent via the pressure relief valve.
