ABSTRACT:
A chamber for keeping perishable material, either liquid or solid, under refrigeration is provided with a tubular metal container that can be filled with pressurized liquid carbon dioxide. When the pressure in the container holding liquid carbon dioxide is dropped to atmospheric pressure, approximately half of the liquid flashes off as vapor and half becomes solid. The container is disposed along the top of the chamber so that refrigeration from solid carbon dioxide therein flows through the chamber by convection currents. Carbon dioxide vapor may flow from the container into the chamber to provide a protective atmosphere for the material therein.
