A low-temperature foods preserving case and a temperature control method therefor, in which a plurality of evaporators, each partitioned by partitioning panels, are arranged correctively in a cooling chamber, for which sequential cooling and defrosting operations are instructed by a timer, so that circulatory passage of the cooling air is formed through said cooling chamber, the foods preserving chamber, and the cooling chamber by means of fans installed in each of partitioned air passages separated by said partitioning panels.

A low-temperature foods preserving case for preserving foods in a closed foods preserving chamber having a door on one side thereof, comprising means for alternately performing cooling and defrosting operations for periods of time in response to output of a timer; said alternately performing means including first and second evaporators arranged in the cooling chamber of the case and connected in parallel for alternately repeating performance of the cooling and defrosting operations; a partition panel arranged between said first and second evaporators for partitioning said cooling chamber to sections associated with corresponding evaporators; fans arranged in said cooling chamber in association with said first and second evaporators for forcibly circulating the air through the foods preserving chamber and the cooling chamber, said fans being kept in continuous running operation for providing constant humidity so that the fan associated with the evaporator that is performing the cooling operation provides the foods preserving chamber with cooled air and the fan associated with the evaporator that is performing the defrosting operation provides the cooling chamber with humid air.
