DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adiabatic air membrane structure, and more specifically, a plurality of cylindrical outer unit membrane bodies and inner unit membrane bodies are continuously formed. The present invention relates to an adiabatic air film structure including an air film structure.

[0002]

2. Description of the Related Art Conventionally, when building a refrigerated warehouse or the like, according to the conventional technology, expensive and large amounts of heat insulating material must be used for a roof or a wall surface in order to enhance the heat insulating effect of the refrigerated warehouse or the like. . In addition, refrigerated warehouses and the like are generally constructed with steel bars, steel frames, etc., so the construction period until completion was long.

[0003] In recent years, as described in US Patent No. 4,477,503, the air pressure inside the structure is made slightly higher than outside the structure to support the air film roof. Large space facilities are widely known. In U.S. Pat. No. 4,477,503, an air pocket or air space is formed between the outer layer sheet and the lining panel, and the air pocket or air space acts as a heat barrier and connects the inside and outside of the air membrane roof. Increase the insulation effect between.

[0004]

However, in such a technique, the air pockets or air spaces merely form an air insulation layer, and the space between the inside and outside of the structure, such as a refrigerated warehouse, is not provided. If a large temperature difference is required, a sufficient heat insulating effect cannot be expected.

The present invention has been made in view of such conventional technology, and has as its object the construction of a lightweight air film structure, which has an extremely high heat insulating effect, eliminates the need for steel work and the like. An object of the present invention is to provide an adiabatic air film structure that can be shortened.

[0006]

In order to achieve the above object, the present invention covers a large space facility by alternately stacking a plurality of cylindrical outer unit membrane bodies and inner unit membrane bodies. And a main refrigerator, a cool air blower for sending cold air sent from the main refrigerator to the inside of the large space facility, and a cool air inside the large space facility to the outer and inner unit membranes. Blower that blows into the body, and outside and inside
The outer unit and the inner unit while cooling the cool air that has passed through the inside of the side unit film body to the main refrigerator and cooling the inside of the large space facility by the cool air sent from the cool air blower. together to support the film body, characterized in that so as to insulate the internal large-space facilities from the outside air by cold air was fed to the outer and inner unit membrane body above the blower.

[0007]

A plurality of cylindrical outer unit film bodies and inner unit film bodies are alternately stacked to form an air film structure, and cool air flows through these outer unit film bodies and inner unit film bodies.
This cold air is cooled by the main refrigerator, and is sent out into the large space facility by the cool air blower. The cold air cools the inside of the large space facility, maintains the inside at a set low temperature, and supports the air film structure from the inside of the large space facility.
Thus with large space facilities inside the cool air cools the inside, it is fed into the outer and inner unit membrane member by further blower, so that the flow inside the outer and inner unit membrane body. The outside of the outer and inner unit membranes is heated by the outside air, and heat is exchanged between the hot air and the cool air sent to the outside to insulate the heat of the outside air into the large space facility. The cool air after the heat exchange is collected in the main refrigerator by the duct, cooled again, sent to the cool air blower, and circulated for use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a large space facility using the insulated air film structure according to the present invention. As shown in FIG. 2, the air membrane structure of the large space facility has an outer unit membrane body 10 formed in a plurality of laterally continuous tubular shapes, and the inside of the large space facility of the outer unit membrane body 10. It is composed of a plurality of inner unit film bodies 20, 20 formed in a tubular shape and continuous in the lateral direction. The outer unit film body 10 has a tubular shape with a spindle-shaped cross section by the outer film 10A on the outside air side and the intermediate film material 10B, and the inner unit film body 20 is formed on the abdomen of the adjacent intermediate film materials 10B, 10B. The inner film material 20A on the inner side of the large space facility to which the ends are adhered has a tubular shape. Outer unit film body 10 and inside
Both ends of the side unit film body 20 are closed and supported by the ground. And, this air film structure is in the shape of a semi-cylindrical dome as a whole, and by the cold air blower 40 described later,
It is supported by making the air pressure inside the large space facility slightly higher than outside the large space facility.

A main refrigerator 30 is arranged outside the large space facility. The main refrigerator 30 has a plurality of ducts 1
It communicates with one end of the outer unit film body 10 via 1 and 11, and also communicates with one end of the inner unit film body 20 via a plurality of ducts not shown. Further, a cold air blower 40 is arranged inside the large space facility, and the cold air blower 40 communicates with a main refrigerator 30 outside the large space facility via a duct 31. Furthermore, inside the large space facility,
A blower 50 is provided. The blower 50 communicates with the other end of the outer unit film body 10 through a plurality of ducts (not shown), and further, the inside through a plurality of ducts 22 and 22 .
It also communicates with the other end of the side unit film body 20.

When the cool air from the main refrigerator 30 is blown out by the cool air blower 40 through the duct 31 into the large space facility constructed as described above, this cold air increases the pressure inside the large space facility. Supports the air film structure, cools the inside, and keeps the inside at a set low temperature.

The cool air is blown into the outer unit film body 10 and the inner unit film body 20 from the blower 50 through the duct 22 and the like, and flows inside the outer unit film body 10 and the inner unit film body 20. . At this time, the outer unit film body 10 and
Since the inside of the inner unit film body 20, particularly the inside of the outer unit film body 10 is heated by the outside air, these outside air and the sent cool air exchange heat. This prevents the heat of the outside air from being transmitted to the inside of the large space facility, so that the inside of the large space facility can be insulated from the outside air. The cold air after the heat exchange is collected in the main refrigerator 30 via the duct 11 and the like, cooled again, and then sent to the cold air blower 40 for circulation and use.

FIG. 3 is a side view showing another embodiment of the heat insulating air film structure according to the present invention. In this example,
A plurality of wire anchors 6 outside the grounded portion of the air film structure
0 and 60 are installed, both ends of the wire 70 are fixed to the wire anchor 60, and the wire 70 is arranged outside the air film structure to prevent the air film structure from shaking due to strong wind or the like.

Further, a part of the film material having an air film structure may be formed into a transparent sheet 80, and the transparent sheet 80 may be used to illuminate the inside of a large space facility.

Furthermore, if the floor inside the large space facility shown in FIG. 1 is made of a floor material having a high heat insulating property, it is possible to prevent external heat from being transferred from the floor surface to the inside of the cooled large space facility,
The heat insulating effect can be made even more effective.
