초록 ▼

An adsorber for removing carbon dioxide is connected to a substantially sealed food storage chamber for scrubbing the storage chamber atmosphere. When the adsorber becomes loaded with carbon dioxide, it is connected to an external atmosphere inlet and an external atmosphere outlet for purging the adsorber with fresh air. Previously scrubbed storage chamber air is introduced into the purged adsorber prior to reconnecting it to the storage chamber so that high oxygen content fresh air is not introduced into the storage chamber.

대표청구항 ▼

The method of controlling the atmosphere in a substantially sealed food storage chamber which comprises, in sequence: circulating air from the food storage chamber through an adsorber and back to the food storage chamber for scrubbing carbon dioxide from the food storage chamber air; circulating external atmospheric air through the adsorber for purging carbon dioxide from the adsorber; displacing external atmospheric air in the adsorber with air from the food storage chamber without introducing such external atmospheric air into the food storage chamber; and again circulating air from the food storage chamber through the adsorber and back to the food storage chamber for scrubbing carbon dioxide from the food storage chamber air. In atmosphere controlling apparatus for a food storage system including: a substantially sealed storage chamber for storing food; first adsorber means for scrubbing carbon dioxide from air passed therethrough; second adsorber means for scrubbing carbon dioxide from air passed therethrough; an external atmosphere inlet; an external atmosphere outlet; and conduit means interconnecting the storage chamber, the first and second adsorber means, the external atmosphere inlet and the external atmosphere outlet; the improvement comprising circulating means for automatically and sequentially effecting at least the following three circulations of air through the conduit means: (1) a first circulation in which purging atmospheric air passes from the external atmosphere inlet through the first adsorber means and out the external atmosphere outlet for purging carbon dioxide from the first adsorber means and storage chamber air is circulated from the storage chamber through the second adsorber means and back to the storage chamber for scrubbing carbon dioxide from such storage chamber air; (2) a second circulation in which air is transferred from the second adsorber means to the first adsorber means such that scrubbed storage chamber air from the second adsorber means is introduced into the first adsorber means and purging atmospheric air in the first adsorber means is displaced from the first adsorber means without being introduced into the storage chamber; and (3) a third circulation in which purging air passes from the external atmosphere inlet through the second adsorber means and out the external atmosphere outlet for purging carbon dioxide from the second adsorber means and storage chamber air is circulated from the storage chamber through the first adsorber means and back to the storage chamber for scrubbing carbon dioxide from such storage chamber air.
