Reefer Container Temperature Records: Accuracy and Cargo Temperature Stability

Moreover, the temperature record provided is from a temperature recorder placed inside the reefer container by the shipper. However, it's important to note that this recorded temperature may not accurately reflect the actual refrigeration temperature inside the reefer container. Factors such as the placement of the recorder, the cargo stowage condition inside the container, and the recorder's own accuracy can all contribute to discrepancies in the recorded temperature.

Furthermore, it's worth mentioning that the temperature difference between the recorded temperature and the actual temperature of the cargo can be even greater. This is due to the significant difference in specific heat capacity between the cargo and the air inside the container. As a result, the temperature of the cargo does not change rapidly in a short period of time. In fact, frozen cargo in a normal refrigerated reefer container can maintain its temperature for several days without freezing, even when the reefer container is not refrigerated.

To summarize, it's important to consider these factors when interpreting the temperature record provided. The recorded temperature may not accurately represent the actual refrigeration temperature inside the reefer container, and the temperature of the cargo can remain stable for several days without refrigeration.
