Abstract
A temperature-controlled transport container (10) has a cargo space (1) for accommodating temperature-sensitive goods and a refrigeration system. The refrigeration system comprises a closed air circuit (2), separate from the cargo space and located outside of and contiguous with at least one wall (9) of the cargo space. The refrigeration system further comprises at least one refrigeration unit (5) configured to cool air in the closed air circuit. The refrigeration system also comprises a pressurizing unit (8) for establishing a pressure difference between the closed air circuit and the ambient environment (20) outside of, but in a vicinity of, the temperature-controlled transport container.
Claims20
A temperature-controlled transport container, said temperature-controlled transport container comprising a cargo space for accommodating temperature-sensitive goods and a refrigeration system, said refrigeration system comprising:
- a closed air circuit, separate from said cargo space, located outside of and contiguous with at least one wall of said cargo space;
- at least one refrigeration unit configured to cool air in said closed air circuit;
- and
- a pressurizing unit for establishing a pressure difference between said closed air circuit and the ambient environment outside of, but in a vicinity of, said temperature-controlled transport container,
- said pressure difference being a higher pressure in said closed air circuit than in the ambient environment.
A method for controlling climate conditions in a temperature-controlled transport container, said temperature-controlled transport container comprising a cargo space, the method comprising:
- cooling air with a refrigeration system in a closed air circuit, said closed air circuit being separate from said cargo space and located outside of and contiguous with at least one wall of said cargo space;
- and
- establishing by a pressurizing unit a pressure difference between said closed air circuit and an ambient environment outside of, but in a vicinity of, said temperature-controlled transport container,
- said pressure difference being a higher pressure in said closed air circuit than in the ambient environment.
