Abstract: Coupling means for an installation for refrigerating containers and intended to provide a seal for a flow of cold air between a refrigeration system and containers to be refrigerated comprises a double sleeve 22, 24 which forms an annular space housing an inflatable envelope 30. A movable portion 60 is displaceable axially by the envelope 30, while still being guided by the sleeves, so as to be applied by way of a sealing joint 38 against the wall 14 of the container, around an opening 16 in the wall thereof.

Abstract: The invention relates to an installation for distributing refrigerated air, wherein an air distributing shaft is provided with a series of pairs of air insufflation orifices and air recovery orifices, two orifices of each pair being connected to a container. A refrigerator-centrifugal fan unit is mounted on the shaft between an air inlet passage and an air outlet passage. On each side of the inlet passage and of the outlet passage, the shaft comprises channels arranged in spike-fashion, which present a sharp reduction in section at the level of each of the air insufflation or recovery orifices. These reductions in section are determined in order to have the same static pressure of insufflation or recovery at the level of the different air insufflation or recovery orifices. The invention is more particularly applied to ships carrying refrigerated containers.
