Crop cultivation facility using geothermal heat{CROPS CULTIVATION FACILITIES USING GEOTHERMAL HEAT}

The present invention relates to a facility for cultivating agricultural crops using geothermal heat, and more particularly, a plurality of vegetation plates on which crops are planted in a cultivation house are arranged in multiple rows, and other ground surfaces other than the vegetation plates are covered with an insulating plate from the outside to the ground surface. Heat is prevented from being transferred to keep the ground at a constant temperature.External air is introduced through a ventilation device to pass through the lower part of the insulating plate for heat exchange, and then the temperature-controlled air is supplied from the lower part of the vegetation plate to the upper part. Cultivation of crops that can increase the growth rate of crops by supplying air with reduced temperature through heat exchange to crops to reduce cooling or heating costs, and increasing the rate of moisture evaporation of the leaves of crops to promote nutrient absorption through the roots of crops. It is about the facility.

In general, a greenhouse, a cultivation house, is mainly used as a means for cultivating plants regardless of the season. Such a cultivation house blocks screen damage while being supplied with sunlight, and can easily control vegetation environments such as temperature and humidity, so that healthy and fast plant cultivation is possible by setting an environment suitable for plant growth.

These cultivation houses can be used in four seasons, and cooling or heating is required depending on the season. Since a number of heat sources are required for such cooling and heating, there is a burden of increasing production costs due to an increase in cooling and heating costs in winter or summer.

Accordingly, in recent years, a method of using geothermal heat has been proposed to reduce the heating and cooling costs.

Korean Patent Registration No. 10-1556550 (registered on September 23, 2015; hereinafter referred to as'priority document 1') proposed a heating system for a green house using geothermal heat and sunlight. The Prior Document 1 relates to a system in which one end of a heat pipe is vertically buried underground, and the other end is combined with a water tank connected to a heating facility inside a green house to absorb geothermal heat and release it to the market. However, the Prior Document 1 has a problem that a large number of construction costs are required according to the drilling, since it is necessary to bury a heat pipe by drilling a few meters in order to use geothermal heat, and a number of drilling operations have to be performed in order to increase the heat exchange area.

Korean Patent Registration No. 10-1818574 (registered on January 9, 2018; hereinafter referred to as'priority document 2') relates to a fan coil cooling and heating system that supplies geothermal heat to a cultivation area of a greenhouse or a facility crop of a building. Prior Document 2 provides a system that uses geothermal water circulated by a geothermal heat exchanger as the circulation fluid of a cooling/heating device in a facility, and additionally installs a make-up water tank, a water level sensor, and a make-up water well on the circulation line of the geothermal water. A device is proposed that immediately replenishes the detection area of the loss in the geothermal water circulation process to enable circulation. However, the prior document 2 has a problem in that a large amount of construction cost is required according to the drilling, since the work of vertically installing the geothermal heat exchange pipe must be performed by drilling deeper than 100m underground.

In addition, since both of the prior documents 1 and 2 are used for lowering the temperature inside the house, a large amount of energy is consumed in order to control the cooling and heating of a large area, which is inefficient.

1A is a cross-sectional view showing a cross-sectional view of a cultivation facility according to the present invention.

As referenced, the agricultural crop cultivation facility 10 according to the present invention includes a cultivation house 20, a shelf 30 installed inside the cultivation house, a vegetation plate 40 placed on the shelf, and the Consisting of a heat exchanger and blower (70) for supplying external air to the interior space of the shelf, the shelf insulation side wall 50 installed on the side of the shelf, and the bottom of the cultivation space, which is the inner floor of the cultivation house. Insulation of the ground may be further improved by further installing an inner heat insulating plate 60 installed on the surface.

First, the cultivation house 20 uses a light-transmitting material such as glass or vinyl to separate the outside and the inside, while only the sunlight is transmitted and incident thereon, so that the photosynthetic effect of the crop is made, or a thermal insulation cover using a light-blocking material is provided. It can be used to create a high-temperature environment that blocks light so that crop cultivation can take place. The cultivation house has a cooling and heating device therein, so that cooling is performed in summer and heating is performed in winter. In addition, a ventilation device may be installed in the cultivation house so that internal air and external air circulate periodically.

In addition, the cultivation house side wall may be provided in a structure in which all or part of the side wall is formed as the house insulation side wall 22 or is added. The house insulation side wall 22 can collect summer cold air up to the height of the house insulation side wall without losing heat to the side, thereby providing a function of minimizing heat loss.

That is, as shown in FIG. 1B, the cultivation house 20 may be formed by forming a part of the sidewall as the house insulation side wall 22 or by adding the house insulation side wall 22. The house insulation side wall may be attached to an inner surface or an outer surface of the side wall of the cultivation house to provide heat shielding to the interior and exterior. In particular, the height of the house insulation side wall 22 is formed such that the planted crops of the vegetation plate placed on the inner shelf at least from the bottom surface can be contained, particularly to the top of the crops. This makes it possible to prevent heat loss at least in the sidewall of the cultivation house by the relatively low temperature air filled in the lower part of the summer season.

Here, the shelf insulation side wall installed on the shelf and the inner insulation plate installed on the bottom surface of the cultivation space may be used without being separately installed.

The shelf 30 includes a first frame 31 formed in the longitudinal direction as a frame made of steel or wood, as shown in FIG. 2A, and a second frame installed vertically so as to place the first frame at a predetermined height on the ground. It is composed of a frame 32 and a third frame 33 that arranges the first frame and the second frame at regular intervals in the width direction. A space is formed inside the frame, and the first frame 31 and the third frame 33 constituting the upper surface have a structure in which a vegetation plate 40 to be described later is placed.

One or more of the shelves 30 may be installed in the cultivation space inside the cultivation house 20, and preferably, shelves formed in the same length as the longitudinal direction of the cultivation house are arranged to be spaced apart at regular intervals in the width direction. .

In addition, both ends of the vegetation plate 40 are placed on the first frame 31 in which a pair is arranged in the width direction as shown in FIG. 2B on the upper part of the shelf 30, but a plurality of the vegetation plates 40 can be placed in a row. As shown in FIG. 2C, the third frame 33 maintaining the spacing of the pair of first frames 31 may be provided in a structure formed at an interval of one vegetation plate 40 or an interval of a predetermined number of units.

The vegetation plate 40 is a plate body in the form of a container in which crops are planted and grown as shown in FIGS. 3A and 3B. The soil is stored inside, and agricultural products are planted therein to allow cultivation to take place. A drain hole of a common potted plant is formed on the bottom of the vegetation plate.

In addition, the vegetation plate 40 is formed with a locking portion 41 extending in an outer horizontal direction along an edge of an upper or lower portion that is a portion that is caught on the shelf, and the locking portion forms a mesh shape or a plurality of through holes from the bottom to the top. Furnace airflow can be made possible.

In addition, as shown in FIG. 3C, a plurality of air distribution pipes 42 are vertically formed on the inner surface of the vegetation plate 40 so that air from the lower portion of the vegetation plate flows through the inlet of the air distribution pipe at the bottom to allow air to be blown upward.

In this way, the gap between the vegetation plates 40, the through hole of the vegetation plate locking part 41, or the upward blowing of the lower air through the air distribution pipe 42 is supplied to the leaves of the crops planted in the vegetation plate and moisture from the leaves of the crops. Evaporation can be made active. When the amount of water evaporation from the leaves of the crop is increased, the amount of nutrient absorption around the roots of the crop is increased due to the osmotic pressure phenomenon, so that plant growth can be promoted by absorption of a large amount of nutrients. In addition, due to the lush leaf layer, airflow is blocked in the space between the surface of the vegetation plate and the leaf layer, preventing the occurrence of mold, and so on, it is possible to cultivate healthy crops.

The shelf insulation side wall 50 may be mounted on the side of the shelf 30 as shown in FIG. 4A to separate the outside and the inside to prevent external heat or cold air from flowing into the inside of the shelf. The shelf insulation side wall 50 may be used by applying a commonly used insulating material. It is preferable that the shelf insulation side wall is subjected to thermal insulation treatment to prevent the introduction of hot or cold air into the joint portion with the adjacent surface. In addition, in the structure in which the heat-shielding space is formed by the house insulation side wall, it may be blocked with vinyl instead of the shelf insulation side wall or may be provided in an open form without the side wall.

In addition, as shown in FIG. 4B, the shelf insulation side wall 50 may be configured to extend higher than the height of the vegetation plate 40 and agricultural products grown on the vegetation plate. This minimizes seasonal temperature variation by storing the air that has been heat-exchanged with geothermal heat, which will be described later, inside the shelf insulation side wall, and stores the upper layer and relatively low temperature air in summer and relatively high temperature air in winter. By shortening the operating time of the main air conditioner, it is possible to reduce heating and cooling costs.

The inner heat insulating plate 60 covers a floor surface other than a floor surface on which a shelf is installed among the floor surfaces of the cultivation space inside the cultivation house to prevent external heat or cold air from being transmitted to the ground surface.

5, when looking at the bottom of the cultivation space inside the cultivation house, the shelf 30 is installed to surround the shelf insulation side wall 50 on the side excluding the top of the shelf so that hot or cold air is transmitted to the inside through the side wall. In addition, the bottom surface where the shelf is not located can be prevented from being transmitted to the ground surface by the inner heat insulating plate 60. In this case, the contact surface between the lower end of the shelf insulation side wall and the inner insulation plate is preferably provided in a structure that prevents hot or cold air from penetrating into the ground surface.

If the heat insulation board is installed on the ground like this, the surface temperature of the center of the heat insulation board will have a temperature distribution similar to that of the point vertically drilled into the ground by the distance from the edge of the insulation board to the center. Accordingly, if sufficient insulation is provided on the ground surface, a temperature similar to the temperature of the depth of the ground as much as 1/2 of the width of the insulation layer can be provided, thereby reducing costs due to underground drilling.

The heat exchanger and blower 70 includes a blower 72 that sucks external air and supplies it to the inside of the shelf, and an air supply pipe 71 that guides the sucked air to the inside of the shelf.

The air supply pipe 71 has a suction side outside the cultivation house, and a discharge side communicates with the inner space of the shelf, and the sung fan 72 is installed in any one of the piping lines of the air supply pipe to control the flow of air. .

Here, the air supply pipe 71 is communicated to the inside of the shelf through the floor of the cultivation house, and when the inner heat insulating plate is installed, it is communicated to the inside of the shelf through the lower portion of the inner heat insulating plate. At this time, the air supply pipe is zig-zag piped from the lower part of the internal insulation plate to heat exchange by contacting the upper part with the insulated surface. In summer, air at a temperature lower than the inlet air is discharged, and in winter, air higher than the inlet air is discharged to the main air conditioner. You can reduce the amount of use.

Here, the air supply pipe 71 is piped in various forms so as to contact the surface between the inner heat insulating plate and the surface to allow heat exchange between the surface and the inlet air, and to increase the heat exchange rate, the air supply pipe is formed to a thin depth (about 1 to 20 cm). The heat exchange rate can be increased by embedding with. In addition, it is possible to increase the heat exchange area by installing a plurality of fins to increase the surface area of the air supply pipe.

As shown in FIG. 6, the present invention can block heat transfer inside and outside the cultivation house through the ground by vertically embedding the buried insulation plate 80 between the cultivation area inside the cultivation house and the open area outside the cultivation house. At this time, the buried heat insulating plate 80 has the upper end to be exposed or placed close to the ground, and the lower end is vertically installed in the ground so that hot or cold air transmitted to the ground outside the cultivation house is transmitted horizontally along the ground. Can be blocked.

In addition, as shown in FIG. 7, an external expansion insulation plate 90 is further installed outside the edge of the cultivation house without installing the buried insulation plate to cover the open ground, which is the open ground outside the cultivation house, to prevent the transfer of heat or cold air transmitted from the open ground. Can be blocked. At this time, the temperature of the ground surface at the edge of the cultivation house is distributed similarly to the temperature of the location drilled underground by the width of the external expansion insulation plate.

In addition, the external expansion insulation plate 90 may be provided in a manner that covers the edge of the cultivation house horizontally, or hinges with the cultivation house side wall so as to be fixed and stored on the side wall of the cultivation house 20 when not in use. Of course, as a method of fixing to the side wall of the cultivation house, a hook may be used or various known means may be applied.

The external expansion insulation plate may be installed alone or together with a buried insulation plate to block heat from the surface of the cultivation house from being transferred to the cultivation house.

As shown in Fig. 8, a foundation shelf 21 is installed on the entire floor surface of the cultivation house 20 to form a space at a certain height from the ground surface, and a support plate 211 is placed on the upper surface of the foundation shelf. It can be configured so that the shelf 30 is placed. Here, the base shelf may have a certain heat insulating action by the support plate, and an inner heat insulating plate 60 may be further installed on an upper surface other than the shelf to increase heat insulation. In addition, the support plate 211 is installed so that the lower part of the shelf 30 and the inside of the basic shelf 21 communicate with each other to allow air to flow.

The height of the base shelf 21 is formed to be at least 20cm or more to form a large volume containing air that is heat-exchanged with the ground surface so that the introduced external air is stagnated on the base shelf for a certain period of time and then supplied to the bottom of the shelf 30. desirable. In addition, although the upper limit of the height of the base shelf is not specified, it is preferable to form within 1 m in order to facilitate the operation.

In addition, the heat exchanger and blower 70 may supply external air into the base shelf 21 and be discharged to the upper part of the shelf 30 by blowing pressure, and at this time, the external air introduced into the base shelf 21 Can allow heat exchange through the entire surface of the ground covered by the base shelf.

In addition, the frame of the base shelf 21 and the frame of the shelf 30 are integrally formed, and the support plate 211 and the inner insulation plate 60 are placed on the upper part of the base shelf between the shelves, and the shelf 30 is placed on the side wall of the shelf. It can be configured to form a heat insulating side wall (50). It is possible to prevent heat loss or cold air loss from occurring in the upper side of the inner space formed by the shelf and the base shelf by the inner heat insulating plate and the shelf heat insulation side wall.

9A to 9C, the agricultural crop cultivation facility 10 of the present invention may allow the excavation space 23 to be formed by fully or partially excavating the inner bottom surface of the cultivation house 20.

The excavation space 23 is configured to include the foundation shelf 21, the shelf 30, the support plate 211, and the inner insulation plate 60 in the excavation space by excavating the entire as shown (Figs. 9A, 9B) Alternatively, it may be provided in a form in which partial excavation is performed so as to bury only the shelf 30 without a base shelf (FIG. 9C).

Here, the excavation space 23 is formed to a depth at which the foundation shelf 21 and the shelf 30 and the vegetation plate placed on the shelf and the entire crop planted on the vegetation plate are contained (FIG. 9A), or the foundation shelf 21 It is formed in various depths, such as excavation to a depth that is inserted into the bay (FIG. 9B), or partial excavation (FIG. 9C) to a depth at which the entire crop planted on the shelf 30 and the vegetation plate is contained without a foundation shelf.

In addition, a house insulation side wall 22 may be formed on the side wall of the cultivation house 20 from the ground surface to the upper side, and the installation height of the house insulation side wall may be formed higher than the height of the crop protruding above the excavation space. This is because the external air supplied by the heat exchanger and blower 70 is heat-exchanged with the bottom of the excavation space to cool, and the cooled air does not cause heat loss to the outside through the sidewall at least up to the height of the house insulation sidewall installation. It can be stored and the amount of operation of the main air conditioner can be reduced.

In addition, the excavation surface insulating side wall 231 may be further formed in the excavation space 23 to prevent heat exchange to the side through the side wall formed by excavation. The excavation surface insulation side wall 231 may be attached to the side wall of the excavation space above the base shelf 21 based on the upper surface. It is attached to the side wall of the upper excavation space. This is a structure to prevent heat loss in the sidewall of the excavation space by heat exchanged through the bottom surface of the excavation space.

When explaining the working state with reference to Figure 1 the agricultural crop cultivation facility 10 according to the present invention configured as described above,

Of the inner floors of the cultivation house 20, all floors except the upper part of the shelf 30 on which the vegetation plate 40 is placed are blocked with the internal insulation plate 60 to prevent the air temperature from being transmitted to the surface, so that the vicinity of the surface is a seasonal factor. The temperature deviation was minimized. In this state, the heating and cooling inside the cultivation house can minimize heat loss by cooling and heating only the air, thereby reducing the cost of cooling and heating.

When the heat exchanger and blower 70 is operated while the vegetation plate 40 is placed on the shelf 30, the outside air is sucked through the air supply pipe 71 piped under the inner heat insulating plate 60, and the inner space of the shelf ( 34), and the air is heat-exchanged through the ground surface or the ground adjacent to the ground surface in the process of moving through the air supply pipe 71. That is, by blocking heat transfer according to the external environment by installing an insulating plate, the ground surface and the ground maintain a constant temperature, which can provide a lower temperature than air in summer and a higher temperature than air in winter.

Heat-exchanged air is supplied to the inner space 34 of the shelf 30, and the air in the inner space of the shelf is discharged upward through the vegetation plates 40 placed by the air pressure of the heat exchanger and blower to be heat-exchanged with the crops. Air can be supplied. At this time, if the height of the shelf insulation side wall 50 is higher than the height of the crop, the crop can be cultivated in the heat-exchanged air layer.

In addition, in order to prevent heat transfer from the ground adjacent to the cultivation house 20 to the ground of the cultivation house, the embedded insulation plate 80 is buried along the edge of the cultivation house to provide a heat shield, or an external expansion insulation plate 90 to the outside of the cultivation house. By installing more, it is possible to keep the temperature of the ground below the cultivation house as constant as possible by blocking heat transfer by the upper air layer on the ground surface near the cultivation house.

In this way, the present invention heat-exchanges the outside air with the ground maintaining a constant temperature to supply the crops inside the cultivation house, thereby reducing the amount of use of the main cooling and heating device inside the cultivation house, and promoting the growth of the crops, thereby increasing the income of the farm.
