An evaporator 7 for generating cold air is provided inside a ceiling 6 of the refrigeration / freezing room 3, and a plurality of outlets 8 are formed in front of the ceiling 6. A plurality of suction ports 9 corresponding to the blowing ports 8 are provided. The suction port 9 continues to a duct 11 provided in the base 2. The duct 11 is provided at the back of the rear wall member 12 and further extends into the ceiling 6. Thus, the cool air 13 is circulated by the circulation fan 17 to the base 2.
, A duct 11 provided in the wall member 12 and an air curtain A circulating through the ceiling 6.

Further, the wall member 14 forming the side walls 14a, 14b is formed of two portions 14a ₁ , 14a ₂ , and 1 respectively.
4b ₁ , 14b ₂ , each part being a hinge 1
5. Therefore, the side walls 14a ₁ and 14b ₁ are configured to be openable and closable with respect to the side walls 14a ₂ and 14b ₂ fixed to the base 2, as indicated by the imaginary line 16. In the present embodiment, the wall members 12, 1
4a, 14b and the ceiling 6 are formed by sandwiching an aluminum plate with a heat-insulating plate material, for example, a foamed resin such as styrene foam.

Next, the operation of the refrigerated / frozen product storage device according to the present embodiment will be described. First, the apparatus is moved to a predetermined position such as an entrance of a refrigerated warehouse (not shown). Open the side walls 14a ₁ and 14b ₁ as shown by the dashed line 16 and
The frozen product 1 is loaded on the base 2. When the loading of the frozen product 1 is completed, the side walls 14a ₁ and 14b ₁ are returned to their original positions to form the refrigerator / freezer compartment 3.

Next, the cool air generating evaporator 7 installed on the ceiling 6 is driven to generate cool air 13, and the circulating fan 17 is turned to circulate the cool air 13. Then
The cool air 13 descends planarly from the outlet 8 to the inlet 9 to form an air curtain A, and shuts off the refrigeration / freezing room 3 from the outside air. Furthermore, the cool air 13 that has entered the duct 11 circulates along the lower portion of the base 2 and along the wall portion 12 to the inside of the ceiling 6. In addition, the circulation fan 17 is configured to have a variable air volume by using an inverter, so that an optimal air circulation amount is ensured.

Since the air forming the air curtain A is cooled by the evaporator 7 for generating cold air, the specific gravity of the cold air 13 is larger and heavier than the surrounding air, so

In this case, it is possible to fall forward by the hinge 15, which is a so-called “fanning”. The ceiling 6 is formed in a smaller area than the base 2, has a built-in evaporator 7 for generating cool air, and has an outlet 8 for blowing out cool air 13. The wall members 14 forming the side walls 14a, 14b are formed in a substantially triangular shape whose one side extends obliquely from the ceiling 6 toward the low-height wall member 18, and each side wall 14a, 14b
Is connected to the rear wall member 12 via a hinge 15.
Due to such a structure, both side walls 14a, 14b
As shown by, the door can be opened.

An evaporator 7 for generating cold air is built in a ceiling 6 having an area smaller than that of the base 2, and cool air 13 is obliquely directed toward a suction port 9 formed in the base 2. A plurality of outlets 8 are provided for blowing to form a planar air curtain A1. The wall members 12, 1
