Remove the refrigerator compartment 1 from the stationary refrigerator, place the refrigerator compartment 1 on a transport device such as a truck 300 using a crane or forklift, and remove the pipes such as the flanges 70 of the circulation paths 25 and 47 provided on the truck 300. The refrigerator compartment 1 is incorporated into a small refrigerator on a truck 300 via a joint. Then, the refrigerating room 1 is transported to a destination by a truck 300 and incorporated into another or the same large-sized refrigerating device provided at the destination. Next, the refrigeration device will be explained.

To explain Fig. 1, 1 is a refrigerating room, 2J is a cooling pipe, and +0.5°C is sent from a tank (not shown).
The water is circulated to cool the wall surface 3 of the refrigerator compartment 1.

30 is a fan, and when it is operated, gases such as air, nitrogen gas, carbon dioxide gas, etc. in the refrigerator compartment 1 pass through the conduit 23 from the outlet 18 provided at the bottom 20, and are transferred to the conduit 25 via the four-way switching valve 22. and is blown into the dust removal cyclone 34.

The conduits 23 and 24 are connected by a pipe joint such as a flange 70 midway, and the refrigerating chamber 1 is removed from a stationary refrigerating device for transportation and incorporated into a small refrigerating device installed in a truck or the like. It's becoming like that. The dust removal cyclone 34
A steam vibrator 35 is attached to the refrigerator compartment 1, which separates solid matter such as dust entrained from the refrigerator compartment 1, and also sterilizes the air by ejecting steam as necessary. However, for convenience, the dust removal cyclone 34 can be omitted and the steam vibrator can be directly passed through the conduit 33''.

Excess moisture due to cooling is condensed and deprived of water, and insufficient moisture is humidified, and the temperature is approximately equal to the chilled water temperature. It becomes saturated and exits through conduit 37. On the other hand, the water that has been deprived of heat dissolves or suspends odors, dirt, germs, etc. in the refrigerator compartment, and is unsuitable for repeated use, so it is passed through the conduit 41 to an overnight overnight machine 42 for filtration, and is filtered through the conduit 4 For this reason, it is preferable that the Okisukoki 42 is a regular Okisoki made by layering an adsorbent such as activated carbon, diatomaceous earth, acid clay, or ion exchange resin. The cooling gas leaving the cold water spray cyclone 36 still carries some droplets,
The wet material is completely dehydrated by the water removal drop cyclone 43.
