- Transport containers are usually equipped with a valve or a door seal that allows air to flow out of the container chamber to the outside (when climbing) or from the outside into the container chamber (when descending) when a specified differential pressure between the environment and the container chamber is exceeded. In the latter case, however, warm ambient air gets into the with the air flow
- Container interior which has a significantly colder temperature compared to the environment, so that the dew point may be fallen below and water may condense from the air.

Because air is only allowed to pass if a predetermined pressure difference is exceeded, the amount of air flowing in can be kept so low that the heat transfer required for pre-cooling the air from the air to the components delimiting the buffer space or the temperature control element is ensured.
- the at least one sealing element is preferably designed in such a way that it allows air to pass through at a pressure difference of 200-300 mbar.

- Total cooling capacity can be divided between the evaporative cooling system and the latent heat storage.
- the cooling system can be designed in such a way that when the performance of the evaporative cooling system is no longer sufficient and the temperature of the chamber increases, the additional cooling performance is drawn from the latent heat storage, which is the energy for the phase transition from solid to liquid
- the cooling system can preferably be designed in such a way that the phase transition temperature (solid to liquid) of the latent heat accumulator is selected to be lower than the temperature resulting from the cooling capacity of the evaporative cooling system.
