Summary

The dramatic changes of interior air temperature and humidity induced by heat and mass transfer can make the quality of food no longer be assured while the door of the refrigerated truck is opened in the distribution. Comparative experiments are conducted according to the problems in the unloading process. The variations of temperature and humidity under different conditions are analyzed. The conclusion shows that the temperature difference between the inside and outside air is the main factor which impact the temperature rise of interior air, and the use of PVC curtain can effectively inhibit the elevated temperature inside the vehicle and ensure food safety to some extent.
