2. Description of the Related Art Conventionally, a plurality of hollow parts are provided inside by integrally forming a pair of parallelly spaced panel parts and a plurality of parallel partition parts provided between the panel parts with a transparent resin. Hollow multi-layer panels are known. Since this type of hollow multi-layer panel is transparent on the whole surface, it is excellent in daylighting property, and furthermore, it has an adiabatic layer inside so that it is excellent in heat insulation and impact resistance. Therefore, it is used as a covering material for greenhouses for cultivating plants such as vegetables and flowers that need to take in sunlight and raise the environmental temperature.

By the way, in the case of mushroom cultivation, although appropriate lighting is required, the environmental temperature is not required as much as that of the plant, and it is desirable that the temperature is set lower. Therefore, since it is difficult to grow mushrooms in a greenhouse whose purpose is to raise the temperature, usually a dedicated cultivation house for mushrooms is constructed and an air conditioner is installed, whereby the temperature and humidity are adjusted appropriately.

However, such a cultivation house requires a large-scale air-conditioning facility, and there is a problem that the facility cost and the maintenance cost are considerably expensive.

The present invention solves the problems existing in the prior art as described above, and provides a hollow multi-layer panel having a simple structure and a cooling function, and by using the panel, a large scale is achieved. The purpose is to provide a cultivation house that does not require air conditioning equipment and can achieve a significant cost reduction.

According to 0), since the zigzag flow passage 7 is formed inside, for example, water as a heat medium is supplied from the supply port 8 to the flow passage 7.
Is supplied to the water, the water flows through the flow passage 7 and is discharged from the discharge port 9. At this time, the water covers almost the entire surface of the hollow multi-layered panel 1 and exchanges heat with the outside air.

Therefore, if the cultivation house 10 is constructed by using one or more hollow multi-layer panels 1 ... For the wall portion W or the roof portion R, the heat of the sunlight from the outside is blocked and the cultivation house 10 is cut off. The inside is cooled. Since the entire hollow multi-layer panel 1 is made of transparent resin, translucency (light collection) is ensured even when water is poured inside. As a result, optimal lighting conditions and relatively low temperature conditions are obtained especially for the mushroom cultivation environment.

In this case, if the water is cooled if necessary, an arbitrary temperature condition is set.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

First, the structure of the hollow multi-layer panel 1 according to the present invention will be described with reference to FIGS. 1 and 2.

The hollow multi-layer panel 1 includes a pair of panel portions 2 and 3 which are separated in parallel and a plurality of parallel partition portions 4 which are provided between the panel portions 2 and 3 and which are made of transparent resin (for example, polycarbonate). Equipped with a panel body 21 integrally molded by
As a result, a large number of hollow portions S ... Of rectangular cross section are provided inside the panel body 21 as shown in FIG. In addition, as shown in FIG.
The side plate portions 5p and 5q formed of the same material as 1 are hermetically sealed, thereby closing both ends of the hollow portions S ...

On the other hand, communication holes 6 ... Are alternately formed at one end or the other end of each partition 4. As a result, the hollow portions S and S adjacent to each other are communicated at both ends thereof alternately, and a zigzag flow passage 7 is formed inside.

Further, one panel portion 2 is provided with a supply port 8 facing one end (start end) of the flow passage 7 and a discharge port 9 facing the other end (end). In this case, in order to completely fill the flow passage 7 with water (heat medium), it is desirable to arrange the supply port 8 on the lower side of the panel body 21 and the discharge port 9 on the upper side thereof, as shown in FIG.

Next, a method of using the hollow multi-layer panel 1 will be described with reference to FIG.

The hollow multi-layer panel 1 can be used as a cooling panel by connecting the heating medium supply section 11. Figure 1
Indicates a heat medium supply unit 11 composed of a cooling unit 25, a pump 26, and a tank 27. The water contained in the tank 27 is sent by the pump 26 and is cooled by the cooling unit 25, and the cooled water is supplied to the supply port. 8 are supplied. Then, the water flowing through the flow passage 7 undergoes heat exchange in the panel portions 2 and 3 and is discharged from the discharge port 9 and the tank 27.
Returned to. At this time, as shown by the arrow H, water is supplied from the lower side of the hollow multilayer panel 1 and moves upward,
The water is completely filled in the flow passage 7. In the figure, 28 is a water supply unit, and 29 and 30 are water distribution pipes connected to the supply port 8 and the discharge port 9. As the simplest configuration of the heat medium supply unit 11, the supply port 8 and the tap of the water supply may be connected by a hose or the like so that the tap water is supplied to the supply port 8 and discharged from the discharge port 9.

Next, a cultivation house 10 using such a hollow multi-layered panel 1 will be described with reference to FIG. FIG. 3 shows the front surface of the cultivation house 10 for mushroom cultivation, and the front wall portion W is constituted by a plurality of, that is, two vertical, horizontal six-row hollow multi-layer panels 1 ...

Therefore, if water is supplied from the heat medium supply unit 11 to the hollow multi-layer panels 1 ... In the cultivation house 10 and mushrooms are cultivated in the cultivation house 10, the heat of the sunlight from the outside is eliminated. The inside of the cultivation house 10 is cooled by being shut off and by the heat exchange action of the hollow multi-layered panel 1. In this case, it was confirmed that the temperature in the house 10 was lowered by 2 to 3 ° C. even when tap water was directly distributed. Since the hollow multi-layer panel 1 is made of a transparent resin, the entire translucency (light collecting property) is hardly deteriorated even when water is poured inside. Therefore, optimal lighting conditions and relatively low temperature conditions can be obtained for the mushroom cultivation environment.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment.
For example, although the heat medium is water as an example, any heat medium such as antifreeze or gas can be used. In winter, it can be used as a heat panel by passing hot water. Therefore, of course, it can be used as a cultivation house for growing flowers and vegetables in winter. In addition, the detailed configuration, shape, material, quantity, etc. can be arbitrarily changed without departing from the scope of the present invention.
