Description

Title: FREIGHT CONTAINER AND METHOD FOR TRANSPORTING

CARGO

TECHNICAL FIELD AND BACKGROUND

The present disclosure relates to a freight container for transporting cargo, especially temperature sensitive cargo. The disclosure further relates to a method for transporting cargo.

Modern society has become increasingly dependent on the long distance transport of cargo. Freight containers are widely used to transport such cargo, e.g. by boat, train, and/or truck. Some cargo, e.g. food, such as fruit, dairy products, meat, etc., but also electronics, may require a climate controlled environment to prevent their deterioration. Temperature and/or humidity sensitive cargo can be transported by a freight container comprising an air conditioning unit. For example, the air conditioning unit can be integrated into the container. To guarantee continuous temperature control, it is desirable to also integrate a power source/generator into the container or air conditioning unit. For example a diesel powered generator and fuel tank can be integrated into the container. However, the extra equipment may affect the available cargo space because the outer dimensions of the container are constrained by international standards. For example, a long range transport container may contain a relatively large fuel tank that occupies part of the cargo space. However, such a design runs counter to the general need for maximizing the cargo capacity of the freight container.

Therefore, a general need exists for a long range, climate controlled freight container or reefer having an increased cargo capacity. For example, a specific need exists to have sufficient cargo capacity to transport thirty-three or more Euro pallets (each with a size of 80 cm x 120 cm) arranged side by side, while keeping climate control for a journey lasting twenty days or more.

SUMMARY

To meet these or other challenges, one aspect of the present disclosure provides a freight container for transporting cargo, especially temperature sensitive cargo. The container comprises a container body enclosing a cargo space for storing the cargo. The container further comprises an air conditioning unit arranged for controlling a temperature and/or humidity in the cargo space. The container further comprises a generator for powering the air conditioning unit. The container further comprises a fuel tank for supplying the generator with fuel, especially diesel. At least part the air conditioning unit is suspended above a cargo floor of the cargo space.

Advantageously, the present arrangement may allow cargo to be placed on the cargo floor below the air conditioning system. By arranging the air conditioning unit at or near a front side of the container opposite a back side provided with one or more doors, the unit can be placed against the front without affecting the doors. For example, at least a part of the air conditioning system can be provided against a top side of the container. By providing an outside of the container body with a cavity protruding inward into the container and accommodating at least part of the air conditioning unit in the cavity, the outer dimensions of the container can be kept within specification, while saving cargo space at least at the floor level. For example, a part of the air conditioning unit, e.g. condenser, may be sticking outside from the container body. By shaping the cavity as an inward step of the container body on the upper front side of the container, the air conditioning unit can be placed through a vertical side wall, yet stay within the constrained perimeter of the container. Advantageously, the cargo floor may extends below the step for allowing cargo to be placed on the cargo floor below the step.

In one aspect, the design made available by the present disclosure can provide a container having an outer length corresponding with the sizes and dimensions of a standard freight container. For example, the freight container can be formed as a 45 foot container, preferably as a so-called 45 ft. pallet wide container. A relevant norm for the standard container dimensions would for example be an ISO standard, such as ISO 668 (1995) or an equivalent standard. The present design allows for a cargo floor that is at least 2.4 meter wide and at least 13.2 meter long, such as to accommodate at least 33 Euro-pallets or EPAL-pallets on the floor (each pallet typically has width x length = 80 cm x 120 cm). For example, 11 rows of 3 pallets (having their longitudinal direction extending in the longitudinal direction of the container/cargo floor) Alternatively, 1 row of 3 pallets (having their longitudinal direction extending in the longitudinal direction of the container/cargo floor) and 15 rows of 2 + 1 * 3 pallets having their longitudinal direction extending in the width direction of the container/cargo floor). The container can be provided with first fitting blocks of which the mutual spacing corresponds to the mutual spacing of a 40 foot container and/or second fitting blocks or so-called corner fittings of which the mutual spacing corresponds to the mutual spacing of the outermost placed fitting blocks of a 45 foot container.

To save further space, the air conditioning unit can be arranged at least partially above the fuel tank. For example, the fuel tank can be arranged flat against an outer hull of the container. Further space can be saved by integrating components. For example the generator can be integrated as part of the air conditioning unit. Alternatively, or in addition to the generator, the container may comprise one or more batteries for feeding the air conditioning unit and/or starting the generator. Advantageously, the battery can be charged by the generator. To save further space, the fuel tank may comprises an L-shape, wherein the battery is accommodated in a cavity formed by the L-shape.

The container may comprise a sensor, especially a temperature sensor, associated with the cargo space, and a controller for controlling the air conditioning system. For example, the controller is arranged for determining whether an air property sensed by the sensor needs to be altered by examining whether the sensed air property is below a predetermined bottom threshold value and/or above a predetermined top threshold value, and for controlling the air conditioning unit such as to alter the air property accordingly.

Another or further problem associated with containers for transporting temperature sensitive cargo is that the batteries of such containers can run low, especially when the containers are transported through relatively cold areas with a relatively cold outdoor temperature (e.g. when being transported overland, for instance by train, e.g. from Europe through Russia to China, or vice versa).

Accordingly, in another or further aspect, the present disclosure provides a freight container for transporting cargo, especially temperature sensitive cargo as described above, or otherwise. The container comprises a cargo space defining a cargo floor, and an air conditioning unit, preferably a cooling and/or heating unit, a battery for feeding the air conditioning unit, a generator, especially a diesel powered generator, for charging the battery at least partly, and a fuel tank for supplying the generator with fuel. The container further comprises a clock and a controller arranged for controlling the generator in order to charge the battery at least partly at a moment when a predetermined time interval has lapsed since the last time the battery is charged at least partly. Alternatively, or in addition, the container further comprises a voltage sensing device and a controller arranged for controlling the generator in order to charge the battery at least partly at a moment when is determined that the terminal voltage of the battery has dropped below a predetermined minimum voltage threshold value. Alternatively, or in addition, the container further comprises a receiver and a controller arranged for controlling the generator in order to charge the battery at least partly based on a control signal received by said receiver.

By providing a wall separating the cargo space from a part of the air conditioning system located behind said wall, said wall can define a cavity for guiding air from the cargo space to the air conditioning unit or vice versa.

In a further aspect, the present disclosure provides a method for transporting cargo, especially temperature sensitive cargo, by means of a freight container. The method comprises providing a freight container, preferably a container as described herein. The container is provided with at least an air conditioning unit, preferably a cooling and/or heating unit. The container is further provided with a battery and a generator, especially a diesel powered generator. The method further comprises sensing an air property of air inside the container, especially the temperature of air inside the container. The method further comprises determining whether said air property needs to be altered by examining whether the sensed air property is below a predetermined bottom threshold value and/or above a predetermined top threshold value. The method further comprises altering said air property when the value of the sensed air property is below said predetermined bottom threshold value, such as to bring said air property above said predetermined bottom threshold value, or altering said air property when the sensed value of the air property is above said predetermined top threshold value, such as to bring said air property below said predetermined top threshold value. The method further comprises at least partly charging the battery by means of the generator at a moment when there is no need to alter the air property of the air inside the container. This may be advantageous for keeping the battery charged also during periods when the air conditioning is not strictly necessary.

Otherwise, the battery may discharge which may also prevent the generator from starting.

In one embodiment, the step of charging the battery at a moment when there is no need to alter the air property of the air inside the container is initiated when a predetermined time interval has lapsed, e.g. when a predetermined time interval has lapsed since the last time the battery is charged at least partly. In another or further embodiment, the step of charging the battery at a moment when there is no need to alter the air property of the air inside the container is initiated when it is determined that the terminal voltage of the battery has dropped below a predetermined minimum voltage threshold value. In another or further embodiment, the freight container further is provided with a receiver, and wherein the step of charging the battery at a moment when there is no need to alter the air property of the air inside the container is initiated by means of a control signal received by said receiver of the freight container. In one embodiment, the air conditioning unit is activated while the air property does not need to be altered based e.g. on temperature. Alternatively, or in addition, the battery can be at least partly charged by means of the generator at a moment when there is a need to alter the air property of the air inside the container.
