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, CO2 content, O2 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.

A process for adjusting and maintaining a refrigerated atmosphere in a container for a storage period comprising: decreasing the temperature of the atmosphere in the container by introducing a liquid nitrogen refrigerant into said container from a supply container carried along with said container; measuring the parameters of temperature, oxygen content, carbon dioxide content, and humidity; circulating said atmosphere prior to measurement of said parameters, and further circulating said atmosphere at time intervals in response to a feedback value of at least one of the parameters for a period determined by said feedback value of at least one of said parameters; increasing said humidity of said atmosphere by humidifying means in response to measured humidity; increasing said carbon dioxide content in response to measured carbon dioxide content by introducing carbon dioxide from a supply container carried along with said container; and increasing said temperature of said atmosphere over a predetermined period immediately prior to the end of the storage period so that the temperature of said atmosphere corresponds to the ambient temperature outside said container expected at said end of said storage period.
