Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a plant factory in which plants are grown by artificially controlling the environment, and particularly relates to a plant cultivation device suitable for controlling environmental conditions. .

[Conventional technology]

Conventional environmental control techniques for plant factories include JP-A-53-92229 and JP-A-58-205432.
In these methods, plants are cultivated by forming a certain space in a greenhouse or an environmental shielding device, and installing cultivation equipment, lamps, etc. necessary for cultivation in this space, but it is difficult to maintain the environment in an optimal state. has not been taken into consideration. Also, since the space is large,
This resulted in waste, such as increased air conditioning capacity and carbon dioxide gas reaching areas where it was not needed.

[Problem that the invention attempts to solve]

The above-mentioned conventional technology is inefficient in terms of optimizing environmental conditions, does not give consideration to economically and efficiently providing the best environmental conditions for cultivated crops, and requires large air conditioning equipment.
This was uneconomical as carbon dioxide gas filled areas unrelated to growth.

The purpose of this invention is to make it possible to install small-capacity air conditioning equipment, to increase production efficiency and economic efficiency, to apply carbon dioxide gas only to areas necessary for cultivation, and to improve environmental conditions. The aim is to increase the growth of plants.

[Means for solving problems]

The above purpose can be achieved by installing another shielding device inside the greenhouse or environmental shielding device.
achieved. In other words, a double shielding device is provided to control only the environmental conditions around the growing plants. As a result, the smaller the space to be controlled, the better the control efficiency will be, and the more economical it will be.

Of course, since light is necessary for plant growth, the shielding device must be light-transmissive. and,
If the heat reflectance is high, the economical efficiency will be further improved.

[Effect]

The space inside the double shield is smaller, making it easier to control strictly. The light emitted from the lamp passes through the shielding device and reaches the plants, promoting photosynthesis, but the heat emitted is reflected by the shielding device and does not raise the temperature of the space where the plants are located, so a small capacity air conditioner is sufficient. . Similarly, since the space is small, temperature can be controlled strictly and efficiently, and carbon dioxide gas only needs to be applied to the space where plants are located, making it economical.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. A space 3 is formed by blocking a space 1 with a shielding device 2, and a lighting device 6 for providing light to plants 17 being cultivated in a cultivation device 4 and a seedling raising device 5 is installed in this space. The cultivation device 4 and the seedling raising device 5 are surrounded by shielding devices 7 and 8 made of a material having light transmittance and heat reflectivity,
Independent and narrow spaces 9, 9' from the space 3 are formed. These spaces 9, 9' are connected to an air conditioner 10 via an exhaust duct 11 and an intake duct 12. A supply pipe 14 from a carbon dioxide gas device 13 is inserted into the exhaust duct 11 . In addition, the shielding device 2 includes an exhaust ventilation fan 15,
An intake ventilation fan 16 is attached.

Although a few percent of the light emitted from the lighting device 6 is blocked by the shielding devices 7 and 8, the majority of the light is emitted from the plants 1 cultivated by the cultivation device 4 and the seedling raising device 5.
7 and provide adequate lighting for cultivation. Further, the heat emitted from the lighting device 6 is emitted into the space 1 by the exhaust ventilation fan 15 and the intake ventilation fan 16, and at the same time, most of it is reflected by the shielding devices 7 and 8, but some of it is transmitted through the space. It reaches 9,9'. The heat in this space is temperature-controlled by an air conditioner 10, and the space 9, 9'
The temperature inside is maintained at an appropriate temperature for the growth of plants 17.
The reflected heat is discharged into space 1 by the exhaust ventilation fan 15 and the intake ventilation fan 16, so the temperature in space 3 becomes lower (however, the temperature in spaces 9 and 9'
If the temperature is low and heating is necessary, use both ventilation fans 1.
5 and 16 are not activated. ), the temperature of the spaces 9 and 9' is also lowered easily by the air conditioner 10. Further, carbon dioxide gas is supplied from the carbon dioxide gas device 13 to the exhaust duct 11 through the supply pipe 14, and the spaces 9, 9'
This leads to the following.

With this configuration, the spaces 9 and 9' are considerably smaller in volume ratio than the space 3, and the space to be controlled becomes smaller and easier to control.

FIG. 2 shows another embodiment, in which the lighting device 6
is surrounded by a shielding device 18, and ventilation fans 15 and 16 for exhaust and air supply are attached to this. Heat generated from the lighting device 6 is directly exhausted into the space 1 by the ventilation fans 15 and 16. According to this embodiment, the device is inexpensive.

[Effect of idea]

According to the present invention, the capacity of the air conditioner can be reduced, and the amount of carbon dioxide gas supplied can be reduced, resulting in a significant improvement in economic efficiency. In addition, the space is smaller, allowing for more optimal environmental conditions, which has the effect of further increasing plant growth.
