Abstract: The invention relates to a cooling process and to a refrigerated container into which nitrogen is delivered, which nitrogen is transported in liquid form in containers with the refrigerated container, at least one cooling system being provided in order to cool the atmosphere of the refrigerated container (1). According to the invention it is provided that the atmosphere is circulated via the cooling system (3) for periods of time given by a control means (13) by at least one blower (44), and that at least one means (6,7,7') for warming the nitrogen before supplying it into the cool room (40), of the refrigerated container (1) is provided, by means of which the nitrogen can be warmed to a temperature substantially corresponding to the temperature within the cool room (40), preferably being only slightly lower than this temperature.

Abstract: The invention relates to a process and an apparatus for the adjustment of maintenance of a refrigerated atmosphere, in particular an atmosphere adjusted to goods stored in a refrigerating tank, in particular a refrigerating container, with the refrigerating requirement exclusively covered by the introduction of cold nitrogen from a supply of liquid nitrogen.According to the invention, the normally immobile atmosphere is forcibly circulated in arbitrarily selected time intervals or in time intervals determined by measured operating parameters (T, CO.sub.2 content, O.sub.2 content, humidity) during time intervals which are predetermined or determined by measured operating parameters.The temporary circulation of the atmosphere is effected by means of a blower actuated by a control means.

Abstract: The invention relates to a transportable refrigerating container in which the atmosphere is passed over a circulating device containing separating means for water and gases, in particular molecular sieves, and refrigerating and humidifying means.
