Abstract: A method and apparatus facilitate lowering the temperature of a cooling module positioned in heat exchange relation to a loaded container to be maintained at a low temperature. The module establishes convective air flow in heat exchange relation to the load without the use of forced air circulation. The module is self-contained and externally accessible to supply water and liquid CO2 to the module interior. Expansion and change in state of the liquid CO2 lowers the temperature of a water ice and CO2 snow mixture in the module. By continuing inflow of CO2 after terminating inflow of water, the mixture can be cooled from about ?76° F. to about ?117° F. Convective air flow in heat exchange relation to the module walls circulates cooling air, thereby eliminating any direct contact of products with the liquid CO2 or CO2 snow formed by the expanding refrigerant.
