| Abstract: |
| To know the effects of different sensors packing methods on fresh environmental data monitoring of
atmosphere controlled container，a comprehensive regulatory test platform of atmosphere controlled container was
set up，liquid nitrogen-filled atmosphere controlled test was carried out，the effects of three different sensor packing
methods，including non-encapsulated，active ventilation and natural ventilation，on fresh environmental data
monitoring，such as temperature，relative humidity and oxygen concentration were compared. The results showed that
the impact of sensor packing method on fresh environmental data monitoring was as follows：temperature，relative
humidity and oxygen concentration. Liquid nitrogen filling under non-encapsulated sensor packing，the temperature
difference between front and rear was the smallest and the rate of cooling around the monitoring point was the fastest.
Natural ventilation sensor packing had significant impact on relative humidity monitoring，the dehumidification rate
lagged behind the other two packing methods. The impact of sensor packing method on oxygen concentration monitoring
was not significant. |
