ADAPTIVE PROTECTIVE GAS FLOW CONTROL IN FREIGHT CONTAINERS

A method for controlling a climate-conditioned gas-flow in a freight container comprises providing (S) of a climate-conditioned gas-flow into a cargo compartment defined by a floor, a ceiling and walls, of which one comprises a door. Measurements of climate conditions are obtained (S) in a gas-flow going into the climate arrangement, going out from the climate arrangement and/or the cargo compartment. The climate-conditioned gas-flow is controlled (S) based on the measurements of climate conditions. The climate-conditioned gas-flow is provided in vicinity of the ceiling, whereby apart of the climate-conditioned gas-flow reaches the container wall comprising a door. A door position is monitored (S), detecting whether the door is open or closed. When the door is monitored to be open, the climate-conditioned gas-flow is deviated (S) as an adaptive protective gas flow over the opening of the open door. A freight container for the method is also disclosed.
