Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a greenhouse that is installed on a purge (floating body) consisting of a substrate and a pipe arranged on the bottom surface of the substrate, and that uses the pipe as a heat exchanger for air conditioning. Regarding floating greenhouses used for

[Conventional technology]

BACKGROUND ART Conventionally, as methods for utilizing groundwater at a temperature of approximately 10° C. to 17° C. for nighttime heating of greenhouses, methods such as a Nenotrainer method, a water curtain method, and a heat pump method have been put into practical use. These systems use underground water at the above-mentioned temperature to raise the room temperature of a greenhouse in an environment where the outside temperature is 14°C to -6°C to about 5°C, which is about 10°C higher than the outside temperature difference.

[Problem that the invention seeks to solve]

However, the method of using groundwater for nighttime heating of the tA room as described above requires unique equipment, such as a polyurethane curtain, a water nozzle, a structure for creating a water curtain and drainage, and a heat pump. , there is a problem that construction costs and equipment costs are high.

In order to efficiently produce plants, it is effective to create an optimal environment for the plants produced by using a plant factory equipped with heating equipment. Therefore, if an economical plant factory that meets these demands could be provided, it would be possible to supply a variety of plants regardless of the season and increase productivity.

Until now, there has been no example of building a plant factory above the water surface based on the idea of using groundwater.

The present invention is based on the above consideration, and aims to provide a floating greenhouse in which a plant factory is floated on the water surface and the inside of the plant factory is air-conditioned using the temperature difference between the water temperature and the air temperature.

[Means for solving problems]

To this end, the floating greenhouse of the present invention includes a substrate, a pipe arranged on the lower surface of the substrate, and a greenhouse installed on the substrate, and the air inside the greenhouse is circulated through the pipe. It is characterized by being configured to perform air conditioning.

[Effect]

In the floating greenhouse of the present invention, the purge is formed by pipes arranged on the bottom surface of the substrate and the m && board, and the greenhouse is installed on the purge, and the air inside the greenhouse is circulated through the pipes, so that the Sufficient buoyancy can be obtained by simply purging the structure. Further, since the pipe is disposed under water on the bottom surface of the substrate, it becomes a heat exchanger that utilizes the temperature difference between the air temperature and the water temperature.

Therefore, the greenhouse can be air-conditioned by circulating air between the pipe and the greenhouse.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 is a diagram for explaining one embodiment of a floating greenhouse according to the present invention, and FIG. 2 is a diagram for explaining a steel purge. In the figure, 1 is a plant factory, 2 is a steel plate, 3 is a pipe, 4 is an air supply fan, and 5 is an exhaust fan.

In Fig. 1, the pipe 3 is a steel pipe and is arranged on the lower surface of the steel plate 2, and together with the steel plate 2 constitutes a steel purge, and the plant factory 1 is installed on top of this steel purge. do.

The plant factory 1 is a so-called greenhouse in which various plants are cultivated under an optimal environment. By circulating the air from the plant factory inside the pipe 3,
is used as a means to obtain buoyancy as a purge, and as a heat exchanger that utilizes the temperature difference between air temperature and water temperature.

Therefore, this floating greenhouse floats on the water surface due to the buoyancy of the pipes 3, the pipes 3 exchange heat in the water, and air conditioning of the plant factory 1 is performed by supplying the air to the plant factory 1 by vaN. Note that the air supply fan 4 and the exhaust fan 5 are used to forcefully circulate the air in the plant factory l through the pipe 3.

Figure 2 shows a plan view of the tAm barge.

As shown in Fig. 2, if the pipe 3 is divided into units instead of having a continuous structure over its entire length, and air is circulated individually to each unit part, in the event that a part of the pipe 3 is damaged, It is also possible to create a structure that does not sink. In this case, although not shown, it goes without saying that a separation means such as a valve is added to the end of each unit part so that when a part of the pipe 3 is damaged, it can be isolated from other unit parts. .

A floating lithium-ion factory with the above configuration can be installed, for example, on a river or river.
By floating on the surface of water such as a lake, a plant factory can be created using a heat exchanger using the Ba-Ib, which takes advantage of the temperature difference between air temperature and water temperature.
It can warm the air inside and provide nighttime heating. Also,
For example, by floating the floating plant factory of the present invention on the water surface near the outlet of heated wastewater from a nuclear power plant, etc.
Waste heat energy from nuclear power plants, etc. can be used effectively.

Note that the present invention can be modified in various ways and is not limited to the above embodiments. For example, the steel plate 2 may be made of concrete or another substrate, and the pipe 3 may also be made of another material instead of a steel pipe.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, a steel purge is constructed of a steel plate and a pipe arranged on the lower surface of the steel plate, and air is flowed into the vibrator, so that a simple purge structure is possible. You can get the buoyancy you need. Furthermore, by installing a plant factory above the purge and circulating the air inside the plant factory instead of liquid such as seawater inside the pipe, the pipe becomes a heat exchanger that reduces the temperature difference between air temperature and water temperature. As a result, the pipes have good durability, making it easy to air condition the plant factory, and reducing costs. In addition, since the air in the plant factory is passed through pipes and circulated, it does not come into contact with water and the air does not become humid.
