ABSTRACT An apparatus for a non-mechanical refrigerated vehicle is disclosed. A rail car (10) has an enclosed storage area (17). A bunker (20) is positioned proximate the ceiling (16) for containing solid refrigerant flakes. Loading manifold (50), supply manifold (70) and the nozzle (75) transfer and convert the liquid CO2 into the solid refrigerant flakes that are directed into the bunker (22). A mesh screen (30) allows for vapor to exit the bunker (22) to the storage area (17). The screen mesh (30) is positioned proximate the first sidewall (11). The sidewalls (11) and (12) have channels (34) and the floor strips (44) have air flow channels (44e) for the flow of air, including vapor. When the refrigerant flakes sublimate in the bunker (22), the vapor flows from the bunder (22) out the screen mesh (30), down the channel (34) of the first sidewall (11), across the air flow channel (44e) and up the channel (34) of the second sidewall (32), all by convection.
