However, when storing living foods such as vegetables and fruits in the refrigerating chamber formed inside this inner box, ethylene is released due to the respiration of the food itself. Gas, carbon dioxide, etc. are discharged into the refrigerator compartment, and the gas composition within the refrigerator compartment changes. However, there is nothing in this low-temperature refrigerator to suppress changes in gas composition, so if the gas composition reaches a state that accelerates food aging during storage of fruits and vegetables, the quality of the food tends to deteriorate and the food quality deteriorates. There was a problem that it could not be stored for a long time. Further, the present invention does not disclose anything about fixing the inner box, and of course does not disclose fixing a member for suppressing changes in gas composition.

うに動作するものである。Note that when the cooling device 14 stops cooling, or due to an increase in the cooling load due to the inflow of outside air or disturbance due to the opening/closing operation of the heat insulating door 8, the temperature inside the storage room increases and the temperature reaches a predetermined temperature that is a certain temperature higher than the set temperature. When the temperature exceeds this temperature, the above-mentioned cooling operation is repeated to maintain the temperature inside the storage chamber at the set temperature.

The gas composition in the storage chamber 10 (
Specifically, the component ratio of various gases contained in the air changes (in particular, the ethylene gas concentration increases). However, the generated ethylene gas is gradually adsorbed by the gas adsorption member 20, and a part of it becomes a circulating cold air flow. Contact with cold air circulation space l
Therefore, the gas adsorption member 20 can suppress the rapid increase in the ethylene gas concentration and slow down the rate at which the gas composition changes. It acts to suppress the temperature and can extend the storage period of fruits and vegetables compared to conventional low-temperature storage.Furthermore, in this example, indirect cooling is performed, so in addition to maintaining a constant temperature and high humidity inside the storage room. By slowing down the rate of change in the gas composition of the air in the storage room, it is possible to suppress the aging of fruits and vegetables and extend the cooling storage period.

It works particularly effectively when controlling cooling operation over a long period of time.
The shelf life of fruits and vegetables can be further extended.

It is possible to suppress a decrease in the adsorption ability of the member.

Since it acts as a mounting part for the part, it is easy to carry.
Moreover, by fixing it in a low-temperature refrigerator, it can form a part of the inner box, and its fixing and removal operations can be easily performed. Furthermore, since the base covers one side of the adsorbent, the base acts as a guard for the adsorbent and can protect the adsorbent from impact from articles.
