REFRIGERATED CHAMBER, IN PARTICULAR IN A REFRIGERATED VEHICLE

摘要

Refrigerated chamber having a wall (11), through at least part of which gas can flow and which has a predefined thickness (s) and an inner side (13) and an outer side (12) between which a plurality of ducts (9) extend, wherein the ducts (9) have a significantly greater length (L) than the thickness (s) of the wall (11) and they connect the interior (14) of the refrigerated chamber to their surroundings. The ratio of the length (L) of the ducts (9) to the thickness (s) of the wall (11) is at least 10, and the ducts preferably have the length of the greater length of the wall. The ducts (9) extend between the inner side (13) of the wall (11) and the outer side (12) of the wall (11) at an acute angle with respect to the inner side (13) or the outer side (12) of the wall (11). The chamber is cooled by a liquefied gas, in particular nitrogen, which is discharged to the surroundings after vaporization through the ducts (9), especially in the ceiling subject to solar radiation.
