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.
