A freight container, comprising:
- a cargo compartment being defined by a floor, a ceiling and walls, wherein at least one of the walls comprises a door;
- a climate arrangement, configured for providing a climate-conditioned gas-flow into said cargo compartment of said freight container,
- wherein said climate-conditioned gas-flow is provided in vicinity of said ceiling of said cargo compartment directly from an output pipe of said climate arrangement at a wall opposite to said wall comprising a door, into a space between an upper gas-flow distributer plate and said ceiling, wherein said upper gas-flow distributer plate extends to said wall comprising a door, wherein at least a part of said climate-conditioned gas-flow reaches said container wall comprising a door,
- wherein upper gas-flow distributer plate constitutes a plane upper limitation of the cargo compartment;
- sensors for obtaining measurements of climate conditions in at least one of a gas-flow going into said climate arrangement, a gas-flow going out from said climate arrangement and said cargo compartment,
- wherein said sensors for obtaining measurements of climate conditions comprises internal thermometers configured for obtaining of an internal temperature of said cargo compartment;
- a control unit configured for controlling climate conditions of said climate-conditioned gas-flow;
- a door position monitoring device, configured to detect whether said door is open or closed,
- wherein, when said door is closed, said at least a part of said climate-conditioned gas-flow reaching said container wall comprising a door is allowed to flow down along the closed door through openings in said upper gas-flow distributer plate,
- wherein said control unit being communicationally connected to said sensors and said climate arrangement,
- wherein said door position monitoring device being communicationally connected to said control unit;
- and by further comprising:
- deviating means, arranged for deviating said at least a part of said climate-conditioned gas-flow as an adaptive protective gas flow over the opening of said open door when said door is monitored to be open;
- and
- ambient thermometer, configured for measuring an ambient temperature, external to said cargo compartment,
- said ambient thermometer being communicationally connected to said control unit,
- whereby said control unit is further configured to control climate conditions of said climate-conditioned gas-flow flowing between said upper gas-flow distributer plate and said ceiling based on a combination of said ambient temperature and said door position,
- wherein said control unit is further configured to increase a flow rate of said climate-conditioned gas-flow by a first predetermined amount as a response to said door being opened, when a difference between said ambient temperature and said internal temperature of said cargo compartment exceeds a first predetermined level.
