ABSTRACT:
A closed loop pipe system is provided for the upper portion of the interior of an insulated storage or transport container. The pipe system includes active pipe sections including spray jet outlets spaced therealong and the active pipe sections are mounted within channel structure recessed within and opening outwardly of at least one insulated wall of the container. The channel structure includes impact plate portions onto which spray jets of liquid CO.sub.2 discharged from the outlets impact for deflecting the spray jets of liquid CO.sub.2 over a load within the container. The pipe system includes upstanding supply pipes at opposite diagonal portions of the container, each including a valve inlet end opening outwardly of a lower portion of the container and an upper end opening into the closed loop pipe system in a manner defining eductor structure whereby rapid inflow of liquid CO.sub.2 under pressure into the closed loop pipe system from either supply pipe will cause circulation of liquid CO.sub.2 in one direction through the closed loop pipe system.
