Abstract
An automatic test system of airflow performance in refrigerator transportation vehicle is proposed and constructed. The wind velocity field of loading area of empty refrigerated compartment is test in this research. The distribution characteristics of the tri-dimensional wind velocity field are analyzed. The plenty vortex areas in the back part of the recurvature area of the refrigerated compartment is beneficial to the uniformity of the temperature field, the flow fields of the loading area are obviously influenced by vortex areas and the face that the area below the return air inlet is most probably one of the temperature blind angles are concluded.
