The box body 14 is attached to the ceiling duct 5 via attachment fittings 17. Incidentally, a drainage pipe 13A is connected to the dew pan 13 for draining defrosting water and the like.

A blower 18 such as a Sirotskov fan is provided at the upper part of the side duct 6, and the air outlet 1 of this blower 18
8A is connected to the suction port 15 of the box body 14.
In addition, a suction port 20 is formed at a suitable location in the lower part of the side wall panel 3 to communicate the inside of the refrigerator with the air passage 6A of the side duct 6, and a prefilter 21 for removing dust is attached to this suction port 20. . Furthermore, a suction port 6B is formed at a suitable location on the side surface of the side duct 6 to communicate the air passage 6A with the outside air, and a prefilter 22 for removing dust is attached to this suction port 6B in the same way as the suction port 20 described above. ing. Further, as shown in FIG. 4, the outlet grill 11

In the prefabricated clean room 1 configured as described above, by operating the refrigeration system and operating the blower 18, air is supplied to the air passage 6A of the side duct 6 through the outside air suction port 6B as shown in FIG. As the outside air flows in, the suction port 2
Air inside the refrigerator flows in through 0. Then, the air sucked in from the outside air suction port 6B and the suction port 20 is blown out from the blower 18, and the air whose pressure has increased is heat exchanged in the evaporator 9, and then passed through the Hepa filter 12.
At the same time, fine dust particles are removed, and bacteria and the like are also removed and blown out from the numerous holes 11A of the blow-off grille 11 into the refrigerator below. Incidentally, when increasing the width of the prefabricated clean room 1 or increasing the cleanliness level, it is sufficient to provide a plurality of ceiling ducts equipped with clean units, and to add side ducts and outdoor units.

Therefore, the ceiling duct 5 connected between the ceiling panels 4 and supported at both ends by the opposing side wall panels 3 of the prefabricated clean room 1 acts as a beam, and furthermore, the ceiling duct 5 serves as a storage space for the clean unit 10. For example, there is no connection part for connecting the clean unit in the middle of the ceiling duct 5 or a connection part between ducts, and as a result, the insulation and airtightness are improved. A clean room 10 with excellent quality can be provided. In addition, since the clean unit 10 is installed in the ceiling duct 5 in advance, at the installation site of the prefabricated clean room 1, the ceiling duct 5 is connected to the ceiling panel 4 and the side wall panel 3, and the clean unit 10 is connected to the outside. Since it is only necessary to perform the connection work with the machine 7 and there is no need to perform the work of installing the clean unit 10 on site, the assembly work can be simplified. Further, the ceiling duct 5 is provided to protrude upward from the upper surface of the ceiling panel 4, and the side duct 6 is provided to protrude upward from the upper surface of the ceiling panel 4.
Since the ducts 5 and 6 are provided so as to protrude outward from the inside of the refrigerator, the ducts 5 and 6 do not protrude into the refrigerator, and the effective storage volume inside the refrigerator can be increased. Moreover, since air is not only sucked in from inside the refrigerator through the suction port 20, but also outside air is sucked in from the outside air suction port 6B and discharged into the refrigerator, the amount of air discharged from the inside of the refrigerator is greater than the amount of air sucked into the ceiling duct 5. The amount of air is large,
The air pressure inside the refrigerator increases to prevent outside air from entering the refrigerator.

Furthermore, since the ceiling panel 4 and the ceiling duct 5 have the same dimensions, the clean unit 1 can be adjusted according to the size or cleanliness of the prefabricated clean room 1.
