ABSTRACT:
A ventilation apparatus for a container for transporting goods by truck or ship. The walls of the container are provided with an inlet opening and an outlet opening, and an inlet unit is connected to the inlet opening and an outlet unit is connected to the outlet opening. The outlet unit is provided with a battery-operated fan for a forced ventilation of the container, temperature sensors are provided for detecting the inner wall temperature and inner air temperature, and a degree of change in the wall temperature per unit of time is calculated for operating the fan when the degree of change in the wall temperature is larger than a predetermined value. Furthermore, the difference between the inner air temperature and the wall temperature is calculated, and the fan is operated when that difference is larger than a predetermined value.
