Description

Agricultural air house system

[0001] The present invention relates to an agricultural air house system, and more particularly, to an agricultural air house system configured to increase heating and cooling energy efficiency through energy storage and supply, and to maintain a comfortable internal environment.

[0002] In general, vinyl greenhouses have excellent heat retention due to their high airtightness, so they are widely used in the agricultural field, especially as spaces for growing, ripening, and drying crops that require a constant temperature. In addition, they can be used for various purposes depending on the user's intention, such as temporary barracks or warehouses.

[0003] These vinyl houses have the advantage of being easier to install and dismantle at lower cost than regular stone structures or plywood structures.

[0004] Typically, a vinyl greenhouse is constructed by forming a skeleton using a steel frame or steel pipes, then covering the steel frame with a synthetic resin film, such as polyvinyl chloride or polyethylene film. Furthermore, ventilation windows, heating and cooling systems, and water supply systems are installed on the surface or inside the greenhouse as needed.

[0005] However, conventional vinyl greenhouses could not be built high above the ground for reasons such as energy efficiency and ease of installation, and there was a large difference in temperature and humidity between the inside and outside of the greenhouse, which led to problems with poor workability for workers.

[0006] An air house, also called an air dome, has been proposed to improve these problems.

[0007] An air house is formed by filling the inside of a membrane member with air without a separate steel frame or pillar, and maintaining the internal pressure higher than atmospheric pressure to keep the membrane member inflated.

[0008] This type of air house has the advantage of being easier to construct on a larger scale than conventional vinyl greenhouses, and thus has a superior working environment inside.

[0009] However, in order to maintain the internal pressure above a certain level, the air house must continuously bring in outside air into the air dome. In this process, hot or cold air from outside may flow into the inside of the air dome, which may interfere with temperature maintenance, and there may also be problems with pollutants such as fine dust flowing in from the outside.

[0010] The present invention was created to solve the above problems, and its purpose is to provide an agricultural air house system capable of storing and supplying energy to increase the cooling and heating efficiency within an air house, and filtering external polluted air and supplying it into the air house.

[0011] An agricultural air house system according to the present invention comprises an inner house extending upward from the ground and expanding by air injected into the interior to form a predetermined internal space, an outer house extending upward from the ground so as to cover the exterior of the inner house and formed to be expandable by air injected into the interior, an air conditioning unit for injecting air into the interior of the inner house and the outer house so that the internal pressure of the inner house and the outer house can be maintained relatively greater than the atmospheric pressure, and an energy storage unit formed in a space formed between the inner house and the outer house or on the ground between the inner house and the outer house, and absorbing and storing thermal energy of air introduced from the outside or supplying thermal energy to the introduced air.

[0012] The air conditioning unit is preferably formed to communicate with the inner house and the outer house, and includes an air conditioning room having an outside air inlet formed on one side for introducing outside air into the interior, and an air injection unit formed on the other side for allowing air to be injected into the inner house and the outer house, an air blower installed in the air conditioning room for injecting air into the interior of the inner house or the outer house through the air injection unit, and an air filter unit for filtering pollutants in the air introduced into the interior of the inner house or the outer house through the air injection unit.

[0013] It is preferable that the above air filter unit include a filter frame corresponding to the outside air intake portion of the air conditioning room, and a plurality of filters installed in the filter frame to filter pollutants in the air that flows into the inside of the air conditioning room through the outside air intake portion.

[0014] The above-mentioned heat storage unit may include a water channel formed on the ground between the inner house and the outer house, and a heat storage material in a fluid state filled in the water channel.

[0015] It is preferable that the above-mentioned heat storage unit further include a heat exchange stick that extends upward from the water channel and is formed of a metal material capable of heat transfer, the lower portion of which is immersed in the heat storage material filled in the water channel, and the upper portion of which is exposed so as to be in contact with air passing through the space between the outer house and the inner house.

[0016] The above heat storage unit further comprises a light reflector that transmits sunlight to the heat storage material side of the water channel during the daytime to induce heat energy to be accumulated in the heat storage material, an auxiliary tank in which the heat storage material can be stored and which is connected to the water channel, a temperature sensor that measures the temperature of the heat storage material filled in the water channel, and a flow portion that causes the heat storage material to flow so as to introduce the heat storage material of the water channel into the auxiliary tank or discharge the heat storage material of the auxiliary tank into the water channel, wherein the light reflector comprises a first reflector installed on the outer side of the inner house so as to reflect sunlight introduced through the outer house toward the inner wall of the outer house, and a second reflector formed so as to reflect the reflected light of the first reflector toward the heat storage material of the water channel, and when the temperature of the heat storage material filled in the water channel measured by the temperature sensor is higher than a preset temperature, the heat storage material whose temperature has increased by the flow portion flows into the auxiliary tank, and the auxiliary tank It is preferable that the storage material be formed so that it can be supplied to the above water channel.

[0017] Since the agricultural air house system of the present invention is formed so that air flowing in from the outside is heat-exchanged while passing through a heat storage unit and then flows into the inner house, high-temperature air releases energy to the heat storage unit to be cooled and then flows into the inner house, and low-temperature air absorbs energy from the heat storage unit to be heated and then flows into the inner house, there is an advantage in that the indoor temperature of the inner house can be efficiently maintained.

[0029]

[0030] FIGS. 1 to 4 illustrate an agricultural air house system (10) according to one embodiment of the present invention.

[0031] Referring to the drawing, the agricultural air house system (10) according to the present invention includes an inner house (100), an outer house (200), an air conditioning unit (300), and a heat storage unit (400) for storing energy.

[0032] The above inner house (100) is designed to expand by air injected into the interior to form a predetermined inner space, and includes an inner membrane whose edges are fixed to the ground.

[0033] It is preferable that the inner membrane be formed to be flexible enough to be expanded by air, yet durable enough not to be torn or punctured by external impact, and, if necessary, a mesh-shaped support part for supporting the inner house (100) may be provided on the outer surface of the inner membrane.

[0034] The above outer house (200) is installed outside the inner house (100), and the outer house (200) is also formed so that it can expand by air injected into the interior by the air conditioning unit (300) described later.

[0035] The outer house (200) is spaced apart from the inner house (100) by a predetermined distance to form a predetermined separation space (hereinafter referred to as “insulation space”), and a support part in the form of a mesh may be provided on the outer surface of the outer membrane constituting the outer house (200) to support the outer house (200).

[0036] The above air conditioning unit (300) injects air into the internal space of the inner house (100) and the outer house (200) so that the inner house (100) and the outer house (200) can maintain an expanded state.

[0037] The above air conditioning unit (300) includes an air conditioning room (310), an air blower (350) installed in the air conditioning room (310), and an air filter unit (360) for filtering air supplied to the internal space of the inner house (100) and the outer house (200).

[0038] The above air conditioning room (310) has an outside air inlet (320) formed on one side to allow outside air to be introduced, and the air filter unit (360) is formed on the outside air inlet (320). In addition, a first air injection unit (330) communicating with the inner house (100) and a second air injection unit (340) communicating with the outer house (200) are formed on the other side of the air conditioning room (310).

[0039] The external air inlet (320) is formed in the form of an inlet hole that is connected to the outside, and the size, shape, and position of the external air inlet (320) are not limited to this embodiment and may be formed in various ways.

[0040] As described above, the first air injection unit (330) and the second air injection unit (340) are formed to be able to inject air by communicating with the inner house (100) and the outer house (200), respectively. In the present embodiment, the first air injection unit (330) is formed on the other side wall facing one side wall of the air conditioning room (310) where the outside air intake unit (320) is formed, and the second air injection unit (340) is formed on the edges on both sides of the air conditioning room (310). However, as long as the first air injection unit (330) and the second air injection unit (340) can communicate with the inner house (100) and the outer house (200), respectively, the formation positions and sizes thereof are not limited to the present embodiment and may be formed in various ways.

[0041] The above air blower (350) is installed inside the air conditioning room (310) and is formed so that air in the air conditioning room (310) can be supplied to the inside of the inner house (100) and the inside of the outer house (200) through the first air injection unit (330) and the second air injection unit (340), respectively.

[0042] The above air blower (350) is provided with a blower fan and a motor for driving the blower fan inside, and is structured so that air drawn in through an intake port connected to the inside of an air conditioning room (310) can be discharged through an exhaust port by the motor and the blower fan. Therefore, the air blower (350) has an exhaust port connected to the first air injection unit (330) or the second air injection unit (340), and it is preferable that the shape and size of the first air injection unit (330) and the second air injection unit (340) are formed to correspond to the exhaust port side of the air blower (350). Even if the exhaust port and the first air injection unit (330) or the second air injection unit (340) do not coincide, a separate extension guide is provided so that the air discharged from the exhaust port does not leak and is entirely introduced into the inside of the inner house (100) or the outer house (200).

[0043] The above air blower (350) is preferably controlled so that the internal pressure of the inner house (100) and the outer house (200) can be maintained at a pressure higher than the set reference pressure, that is, higher than the atmospheric pressure. A separate pressure sensor is provided inside the inner house (100) and the outer house (200), so that when the internal pressure of the inner house (100) and the outer house (200) is lower than the set reference pressure, the air blower (350) can be automatically controlled to operate, or an alarm signal can be sent to a terminal or PC monitored by the manager so that the manager can apply an operation signal to the air blower (350).

[0044] The above air filter unit (360) is intended to remove contaminants in the air flowing into the internal space of the inner house (100) and the outer house (200) through the air blower (350) as described above, thereby allowing clean air to flow in.

[0045] In the present embodiment, the air filter unit (360) is configured to filter air passing through the outside air intake unit (320), and includes a filter frame (361) corresponding to the outside air intake unit (320) and filtering filters (362) installed in the filter frame (361) to filter pollutants in the air.

[0046] The above filtration filter (362) can be applied with various filtration methods depending on the filtration target. The filtration filter (362) can be configured to install a filtration filter (362) that can filter the filtration target by selecting one type depending on the filtration target, but it can also be configured to form a filter module by overlapping a plurality of filtration filters (362) of different filtration methods, and to form a filter module such that air is introduced into the air conditioning room (310) while passing through all of the filters provided in the filter module and having fine dust, bacteria, viruses, etc. removed by each of the filtration filters (362).

[0047] In addition, in the case of the present embodiment, the air filter unit (360) is installed in the outside air intake unit (320) and is formed in a manner to filter all of the air flowing into the air conditioning room (310). However, unlike this, filter devices may be individually formed on the intake port side of the air blower (350) so that air in the same state as outside air flows into the air conditioning room (310) and is filtered during the process of flowing into the air blower (350). In this case, although the number of filter devices increases, the size of each filter becomes smaller, making it easy to replace or repair a single filter.

[0048] The above-mentioned heat storage unit (400) stores heat energy and supplies the stored heat energy into the inner house (100) when the outside temperature drops, such as at night or during rainy weather, thereby facilitating temperature control of the inner house (100) and minimizing costs associated with heat energy management.

[0049] The heat storage unit (400) of the present invention is configured to include a water channel (410) formed on the ground between the inner house (100) and the outer house (200), and a heat storage material (420) in a fluid state filled in the water channel (410).

[0050] The water channel (410) extends along the area between the inner house (100) and the outer house (200) in a form that surrounds the exterior of the inner house (100), and is formed so that it can be filled with a heat storage material (420) by being inserted downwards to a predetermined depth.

[0051] Although water was used as the above heat storage material (420), other types of heat storage material (420) other than water may be used.

[0052] Air introduced into the internal space of the external house (200) through the second air injection unit (340) from the above-mentioned air conditioning room (310) passes through the insulation space (210) between the internal house (100) and the external house (200) and then enters the internal house (100). The internal house (100) is provided with an exhaust unit that is connected to the outside, so that the internal pressure of the internal house (100) is maintained so as not to rise above a certain level while the air is exhausted from the internal space of the internal house (100) to the outside.

[0053] Although not shown, the exhaust part can be formed to be able to adjust the size of the exhaust hole or to be opened and closed, and it is preferable to control the operation of the air blower (350) of the air conditioning unit (300) according to whether the exhaust port is open or the size of the open area so that the internal pressure of the inner house (100) and the outer house (200) can be maintained at a certain level.

[0054] The air introduced into the insulated space (210) through the air blower (350) exchanges heat with the heat storage material (420) of the heat storage unit (400), i.e., water, while passing through the insulated space (210), thereby controlling the temperature. That is, during the day when the outside temperature is high, when the outside air is introduced into the insulated space (210), the water filled in the water channel (410) is heated, and in the process of heating the water, heat loss occurs, and the air with a lowered temperature is introduced into the inner space of the inner house (100). Therefore, it is possible to prevent the internal temperature of the inner house (100) from becoming excessively high due to the outside air, or to minimize the temperature increase.

[0055] Conversely, at night when the outside temperature is low, the air flowing into the above-mentioned insulated space (210) receives heat energy from the water in the water channel (410) and is supplied to the inner house (100) with an elevated temperature.

[0056] Of course, although the outside air is directly supplied to the inner house (100) through the first air injection unit (330), the temperature of the inner house (100) can be prevented from rising excessively during the day or falling excessively at night due to the air that exchanges heat while passing through the insulating space (210), and if necessary, the operation of the air blower (350) that directly supplies the outside air to the inner house (100) through the first air injection unit (330) can be stopped or the number of units in operation can be reduced to minimize the amount of outside air directly supplied to the inner house (100) and to supply the outside air to the inner house (100) after passing through the insulating space (210), thereby inducing efficient temperature control.

[0057] The above heat storage unit (400) may further include a heat exchange stick (430) to facilitate heat exchange between air introduced into the insulation space (210) and water, which is a heat storage material (420), as shown in FIG. 5.

[0058] The above heat exchange stick (430) is formed of a metal material to enable heat transfer, and the lower part is filled with a heat storage material (420) in a water channel (410), i.e., water, and the upper part can be formed to be exposed so as to be in contact with air passing through an insulating space (210).

[0059] In the absence of the above heat exchange stick (430), the air passing through the insulation space (210) only comes into contact with the surface of the water filled in the water channel (410), so the area for heat exchange is bound to be very small. In particular, as the distance between the inner house (100) and the outer house (200) increases, the area of ​​the outer house (200) becomes excessively large, which increases the cost of construction. Therefore, it is desirable that the distance between the outer house (200) and the inner house (100) be formed relatively short. In this case, since the width of the water channel (410) is very limited, the depth of the water channel (410) must be made deep in order to increase the amount of water, which is the heat storage material (420).

[0060] Therefore, in order to increase the heat exchange efficiency between water and air passing through the insulation space (210) under these conditions, a heat exchange stick made of the metal material is provided. The heat exchange stick (430) may be made of an aluminum alloy or copper alloy having excellent heat exchange capacity.

[0061] Alternatively, the heat exchange stick (430) may be composed of a heat pipe rather than a single metal material.

[0062] FIGS. 6 and 7 illustrate another embodiment of a heat storage unit (400).

[0063] The heat storage unit (400) of the present embodiment comprises a light reflecting portion (440) provided in the inner house (100) and the outer house (200) to more effectively heat the heat storage material (420) of the water channel (410) through sunlight during the day, an auxiliary tank (450) in which the heat storage material (420) can be stored and which is connected to the water channel (410), a temperature sensor (460) that measures the temperature of the heat storage material (420) filled in the water channel (410), and a flow portion that induces the heat storage material (420) to be introduced into or discharged from the auxiliary tank (450).

[0064] The above light reflecting portion (440) includes a first reflecting member (441) formed on the outer side of the inner house (100) and a second reflecting member (442) installed on the inner side of the outer house (200).

[0065] The above outer house (200) and inner house (100) are formed of a material that allows light to pass through so that sunlight can enter the inner side of the inner house (100) during the day. A first reflective member (441) is installed in the inner house (100) so that some of the sunlight that passes through the outer house (200) can be reflected. However, since sunlight must also enter the inner space of the inner house (100) for the growth of crops grown in the inner house (100), it is preferable that the first reflective member (441) be installed on the side of the inner house (100) so as not to obstruct sunlight from entering through the upper side.

[0066] The second reflective member (442) is installed on the inner surface of the outer house (200) and is formed so as to reflect sunlight reflected through the first reflective member (441) back toward the water channel (410).

[0067] Since the inner house (100) and the outer house (200) have a convexly curved shape toward the outside, it is difficult to directly reflect light toward the water channel (410) formed on the ground through the first reflective member (441) installed in the inner house (100). Therefore, the first reflective member (441) reflects light toward the second reflective member (442), and the second reflective member (442) reflects light toward the water channel (410), thereby transmitting the thermal energy of sunlight to the water channel (410).

[0068] The first reflective member (441) and the second reflective member (442) can be formed in a shape capable of focusing sunlight into a predetermined area.

[0069] The above auxiliary tank (450) is formed to be connected to the water channel (410) so that the heat storage material (420) filled in the water channel (410) can be introduced and stored or discharged.

[0070] The auxiliary tank (450) is formed of an insulating material and has a storage space provided therein in which a predetermined amount of heat storage material (420) can be stored. The auxiliary tank (450) is connected to a flow unit, and the flow unit serves to introduce heat storage material (420) of a water channel (410) into the auxiliary tank (450) or to discharge heat storage material (420) stored in the auxiliary tank (450) into the water channel (410). In the present embodiment, since water is used as the heat storage material (420), the flow unit is configured to include a first water pump (471) that introduces water of the water channel (410) into the auxiliary tank (450), and a second water pump (472) that discharges water of the auxiliary tank (450) into the water channel (410).

[0071] The above temperature sensor (460) includes a first temperature sensor (461) installed in the water channel (410) to measure the temperature of the storage material (420), and a second temperature sensor (462) installed in the auxiliary tank (450) to measure the temperature of the storage material (420) stored in the auxiliary tank (450).

[0072] Depending on the temperature of the heat storage material (420) measured by the temperature sensor (460), the fluid unit is driven to introduce the heat storage material (420) into the auxiliary tank (450) or to discharge the heat storage material (420) of the auxiliary tank (450) into the water channel (410). For example, when the air temperature is high during the day and it is necessary to lower the air temperature, the outside air introduced into the insulated space (210) exchanges heat with the heat storage material (420) filled in the water channel (410) while passing through the insulated space (210), and then the temperature is lowered and then introduced into the inner house (100). Then, the temperature of the heat storage material (420) that has absorbed heat energy gradually increases. When the temperature of the heat storage material (420) measured by the first temperature sensor (461) reaches a preset temperature at which it is determined that it is difficult to lower the temperature of the outside air, the first water pump (471) is operated to introduce the heat storage material (420) filled in the water channel (410) into the auxiliary tank (450). Then, the heat storage material (420) stored in the auxiliary tank (450) is discharged into the water channel (410) through the second water pump (472) so that it can absorb heat energy from the outside air.

[0073] On the contrary, at night, heat is transferred from the heat storage material (420) filled in the water channel (410) to the outside air, and the outside air is heated and flows into the inner house (100), so that the internal temperature of the inner house (100) can be maintained at a certain level even at night without a separate heating device, or the operation of the heating device can be minimized. If the temperature of the heat storage material (420) filled in the water channel (410) becomes lower than the preset temperature, the heat storage material (420) in the water channel (410) can be sent to the auxiliary tank (450), and the heat storage material (420) in the heat storage state filled in the auxiliary tank (450) can be discharged to the water channel (410) to ensure continuous supply of heat energy.

[0074] In this way, the heat storage performance of storing heat energy in the air in the heat storage unit (400) can be improved through the auxiliary tank (450) and the heat storage material (420) filled in the auxiliary tank (450).

[0075] The agricultural air house system (10) according to the present invention described above can maintain an inflated state through air pressure injected into the interior without a separate frame, and because there is no frame, the size of the internal space can be made relatively large.

[0076] In addition, the agricultural air house system (10) of the present invention can remove contaminants from the outside air and then inject them into the inside, and can control the temperature of the air flowing into the inside house (100) by absorbing or releasing heat energy through the heat storage unit (400), thereby minimizing additional costs for temperature control.
