Study on the Automatic Test Device of Airflow Performance in Refrigerator Transportation Vehicle

In order to test the environment inside the refrigerator transportation vehicle, a automatic test system of airflow performance is built based on monitor and control system of CAN bus. The parameters of flow field such as humiture, wind speed, wind direction and pressure can be collected movably, processed and monitored in realtime with the proposed system, which is helpful for the design and manufacture of refrigerator transportation vehicle.
