The present invention relates to a cold insulation system in which the cold insulation structure partitioned by the above is provided in the internal space independently of the internal space.

In recent years, the development of cold chains for perishable foods has progressed rapidly, and pre-cooling in production areas → low-temperature transportation by vehicles, etc. → temperature management at distribution centers and mass retailers → cold chains such as refrigerator storage at home have been established It was.
In such a cold chain, fresh food after production is immediately pre-cooled at the production area and transported by vehicles equipped with refrigeration equipment. It is inevitable that the freshness of the fresh food product will be reduced to some extent by breaking the cold chain during transportation.

Patent Document 1 (Utility Model Registration No. 2507623) and Patent Document 2 (Japanese Utility Model Publication No. 56-93192) as systems for managing the temperature of foodstuffs in the foodstuff distribution channel including the cold chain. Is provided.

  However, in the technique of Patent Document 1, food (banana) is stored in a carton box and stacked in a maturing room, and the supply amount of cooling air and hot air is adjusted and maintained at an appropriate temperature. Therefore, it is necessary to open and close the entrance / exit of the aging room by a door or the like, and it is difficult to maintain the temperature of the food at an appropriate temperature due to the inflow of outside air when the entrance / exit is opened / closed. In addition, since the interior space of the building is an aging room, it is impossible to cope with changes in food storage capacity and installation location, and the entire aging room is temperature-controlled, so only the necessary area in the building is used. It cannot be cooled.

Since it is directly supported, the installation position is fixed in the cold room, and the cold room cannot be formed in any area of the internal space of the building. In addition, since the air cooler is fixed at the center of the cold storage chamber, the low-temperature air from the air cooler does not hit the cold insulation (fruits and vegetables) evenly, especially when the storage amount of the cold insulation changes. Unevenness is likely to occur.
Further, in such a prior art, when the side movable partition wall is pushed upwards and contracted to put in or out the cold storage material (fruits and vegetables), the outside air flows into the cold storage chamber from the opening, and the temperature in the cold storage chamber is reduced.
