A device 26 is arranged. Here, the double skin structure reduces the temperature change in the building by providing a double structure inside the building with a partition facing the building outer wall and ventilating the inside of the double structure. It is an outer wall structure. In addition, in FIG. 1, the figure shown by the left side is a front view at the time of seeing the cultivation room 50 from the living room 40 side of the building to which the plant growth system 1 in a building is applied, and is shown by the right side.

Is trying to optimize.

  The living room 40 is a living room space for a person surrounded by the ceiling 42 of the living room, the floor surface 44 of the living room, the boundary portion 18, and a side wall (not shown). As described above, the living room 40 is in contact with the cultivation room 50 through the boundary portion 18.

And in the boundary part 18, the air supply / exhaust device 30 which ventilates the air of the cultivation room 50 and the living room 40 mutually is installed in the upper part of the window glass 28. FIG. The air supply / exhaust device 30 is a ventilation device that includes a fan and ventilates in both directions from the living room 40 to the cultivation room 50 and from the cultivation room 50 to the living room 40.

  Inside the cultivation room 50, various sensor groups 32 for measuring temperature and carbon dioxide concentration, an artificial illumination 34, a light-shielding curtain 36, and a wavelength control color roll film 38 are further installed. Further, the plant growth system 1 in the building is further provided with a sensor group 46 including a temperature sensor and a carbon dioxide concentration measurement sensor in the living room 40 and a temperature sensor 48 facing the outside, and the room temperature of the living room 40 and the outdoor air temperature are provided. And can be measured respectively. Measurement data such as temperature and carbon dioxide concentration measured by the sensor group 32, sensor group 46, and temperature sensor 48 are transmitted to the plant growth control apparatus 100 shown in FIG. The plant growth control device 100 analyzes the measurement data transmitted from each sensor, and controls the operation of the air supply / exhaust device 30, the opening / closing of the ventilation damper 20, the lighting of the artificial lighting 34, and the like based on the analysis result.

  In FIG. 2, the functional block diagram of the plant growth control apparatus 100 which concerns on this embodiment is shown. As shown in FIG. 2, the plant growth control device 100 includes a measurement information acquisition unit 102, a ventilation control unit 110, and an artificial lighting control unit 112. The measurement information acquisition unit 102 further includes a temperature acquisition unit 104, a carbon dioxide concentration acquisition unit 106, and a photosynthetic effective radiation amount acquisition unit 108, and functions as an interface for importing measurement data acquired by each unit into the plant growth control device 100. .

  The temperature acquisition unit 104 is measured by a temperature sensor included in the sensor group 32 installed in the cultivation room 50, a sensor group 46 including a temperature sensor that measures the temperature of the living room 40, and a temperature sensor 48 that measures the outside air temperature. Receives temperature data output. The temperature acquisition unit 104 may acquire temperature data from each temperature sensor at predetermined time intervals by wired or wireless data transmission.

  The carbon dioxide concentration acquisition unit 106 receives the output of carbon dioxide concentration data measured by a carbon dioxide concentration sensor included in the sensor group 32 installed in the cultivation room 50. Further, the carbon dioxide concentration acquisition unit 106 may further receive an output of carbon dioxide concentration data measured by a carbon dioxide concentration sensor included in the sensor group 46 installed in the living room 40. The carbon dioxide concentration acquisition unit 106 may acquire temperature data from the carbon dioxide concentration sensor at predetermined time intervals by wired or wireless data transfer.

The photosynthetic effective radiation amount may be calculated as a predetermined ratio of the solar radiation amount, for example, 45%. Here, the amount of solar radiation (W / m ² ) may be acquired from a solar radiation amount measuring sensor installed in a building, or may be acquired from an external database such as the Japan Meteorological Agency. The sensor group 32 installed in the cultivation room 50 may include a photosynthetic effective radiation meter that measures the photosynthetic effective radiation amount. It is good also as acquiring photosynthetic effective radiation amount with a radiation meter.

  The ventilation control unit 110 determines whether the temperature acquired by the temperature acquisition unit 104 and the carbon dioxide concentration acquired by the carbon dioxide concentration acquisition unit 106 satisfy a predetermined condition, and based on the determination result The operation of the air supply / exhaust device 30 and the ventilation damper 20 is controlled. The ventilation control unit 110 transmits control signals for controlling the operations to the air supply / exhaust device 30 and the ventilation damper 20 to control each unit. Hereinafter, details of the control of the air supply / exhaust device 30 and the ventilation damper 20 by the ventilation control unit 110 will be described.

  Here, the ventilation control based on the temperature acquired by the temperature acquisition unit 104 in the ventilation control unit 110 will be specifically described with reference to FIG. In FIG. 3A, the air supply / exhaust device 30 is operated based on the comparison between the temperature θg of the cultivation room 50 and the temperature θi of the living room 40, and ventilation is performed between the living room 40 and the growing room 50. Operating conditions are indicated.

  The temperature of the cultivation room 50 shall be ventilated by setting this temperature range as a target temperature range, for example, when the appropriate temperature of the plant to be grown is 18 degrees to 20 degrees. The appropriate temperature range may be set as a temperature range in which the amount of sugar produced by the plant by the amount of photosynthesis is greater than the amount of sugar consumed by the plant by respiration. The ventilation control unit 110 operates the air supply / exhaust device 30 if θg is less than 18 degrees and the room 40 has a higher room temperature than the cultivation room 50, that is, θg <θi. Ventilate between 40 and cultivation room 50. If θg ≧ θi, the air supply / exhaust device 30 is not operated. If θg is within the target temperature range, that is, 18 ≦ θg ≦ 20, the air supply / exhaust device 30 is not operated. If θg exceeds the target temperature range and the room 40 has a lower room temperature than the cultivation room 50, that is, if θg> θi, the air supply / exhaust device 30 is operated to move the room 40 and the cultivation room 50. And the air supply / exhaust measure 30 is not operated if θg ≦ θi.

  FIG. 3B shows operating conditions when the cultivation room 50 and the outside air are ventilated by the ventilation damper 20 according to the relationship between the temperature θg of the cultivation room 50 and the outside temperature θo. The condition for opening the ventilation damper 20 is that θg is outside the target temperature range, as in the case of the ventilation by the air supply / exhaust device 30 described above, and the outside air temperature θo is closer to the target temperature range than θg. It is.

  Next, ventilation according to the carbon dioxide concentration Φg in the cultivation room 50 will be described with reference to FIG. FIG. 4 shows operating conditions of the air supply / exhaust device 30 and the ventilation damper 20 according to the concentration range of Φg.

  In this embodiment, for example, when the carbon dioxide concentration (target concentration range) necessary for optimal photosynthesis of a plant is 350 to 1000 ppm, the carbon dioxide concentration Φg of the cultivation room 50 is less than 350 ppm. The exhaust device 30 is operated to take in air from the living room 40. This is because the living room 40 has people and the carbon dioxide concentration is higher than that of the cultivation room 50. On the other hand, when Φg exceeds 1000 ppm, the ventilation damper 20 is opened and the outside air is taken into the cultivation room 50. This is because the outside air has a lower carbon dioxide concentration than in the building. When the carbon dioxide concentration Φg is within the target concentration range, neither the air supply / exhaust device 30 nor the ventilation damper 20 is operated to perform ventilation. Moreover, the operating condition of ventilation based on the carbon dioxide concentration is not limited to the above. For example, when the carbon dioxide concentration Φg of the cultivation room 50 is less than a predetermined concentration range, ventilation is performed between the living room 40 and the cultivation room 50 only when Φg is thinner than the carbon dioxide concentration of the living room 40. It is good as well. Further, when the carbon dioxide concentration Φg in the cultivation room 50 is larger than the predetermined concentration range, if Φg is smaller than the carbon dioxide concentration in the living room 40, ventilation may be performed between the living room 40 and the cultivation room 50. It doesn't matter.

  Of course, the inside of the cultivation room 50 may be ventilated by combining the air supply / exhaust device 30 and the ventilation by the ventilation damper 20. In that case, it may be determined in advance which of the ventilation for making the room temperature appropriate and the ventilation for making the carbon dioxide concentration appropriate. Moreover, it is good also as changing the air volume of the fan by the air supply / exhaust device 30 according to the amount of surplus air in a living room.

  The artificial illumination control unit 112 controls the lighting of the artificial illumination 34 based on the photosynthetic effective radiation amount data acquired by the photosynthetic effective radiation amount acquisition unit 108. Hereinafter, the irradiation control of the artificial illumination 34 according to the amount of solar radiation incident on the cultivation room 50 performed by the artificial illumination control unit 112 will be specifically described with reference to FIG.

FIG. 5 is a diagram for explaining the control of the artificial illumination 34. As shown in FIG. 5, the artificial lighting control unit 112 measures the total value (MJ / m ² ) of the daily photosynthetic effective radiation amount acquired by the photosynthetic effective radiation amount acquisition unit 108, and for the most recent predetermined number of days. The total amount of photosynthetic effective radiation (for 4 days in the present embodiment) is summed, and it is determined whether or not the total value has reached the reference integrated photosynthesis effective radiation amount. Note that the reference integrated photosynthesis effective radiation amount may be set to 50% of four days in the monthly average solar radiation amount based on statistical data. When the artificial illumination control unit 112 determines that the total value of the photosynthetic effective radiation amount has not reached the reference integrated light synthesis effective radiation amount, as shown in FIG. Supplies the plant with the effective radiation amount of photosynthesis. On the other hand, as shown in FIG. 5B, when it is determined that the photosynthetic effective radiation amount has reached the reference integrated light synthesis effective radiation amount, the artificial illumination 34 is sufficient because the photosynthetic effective radiation amount is sufficient. Do not light up.

  The operating conditions of the artificial illumination 34 are not limited to those described above. For example, in addition to the total amount of past solar radiation being lower than the standard integrated photosynthesis effective radiation amount, the current solar radiation amount is seasonal. The artificial illumination 34 may be turned on when it falls below a predetermined reference value every time. It should be noted that the lighting time of the artificial illumination 34 may be determined according to the insufficient amount of photosynthetic effective radiation.

  Next, the reference | standard at the time of opening and closing the light-shielding curtain provided in the cultivation room 50 is demonstrated, referring FIG. 6 (A). In the present embodiment, how much the light-shielding curtain is opened and closed is determined based on the temperature in the cultivation room 50 and the amount of photosynthesis effective radiation into the cultivation room 50. Here, the “open” state of the light-shielding curtain means a state in which sunlight incident on the cultivation room 50 is not blocked by the light-shielding curtain, and the “closed” state of the light-shielding curtain means light incident on the cultivation room 50. It means a state where it is blocked by a light blocking curtain.

As shown in FIG. 6A, when the temperature θg in the cultivation room 50 is within 35 degrees, the light-shielding curtain is in the “open” state. On the other hand, when θg exceeds 35 degrees, if the photosynthetic effective radiation amount Sg is less than 200 W / m ² , the light-shielding curtain is opened, and Sg is 200 W / m ² or more and 250 W / m. When it is less than m ² , the light shielding curtain is closed by 70%, and when Sg exceeds 250 W / m ² , the light shielding curtain is closed by 90%. Of course, how much the light-shielding curtain is closed according to Sg may be appropriately changed.

  In addition, it is known that the wavelength of light that promotes the optimal growth of plants is determined according to the growth stage. Therefore, in the present embodiment, the wavelength of the light applied to the plant is changed according to the growth period of the plant by using the wavelength control color roll film 38 provided in the cultivation room 50. FIG. 6B shows what wavelength light is irradiated to the plant in accordance with the growth stage of the plant.

  As shown in FIG. 6B, in the initial stage of growth, that is, for several days after seedling planting, the plant is irradiated with blue light by the blue wavelength control color roll film 38 having a wavelength range of 400 to 500 nm. And in the growth stage of the growth, that is, the time when fruits are formed, the plant is irradiated with red light by the red wavelength control color roll film 38 having a wavelength range of 650 to 700 nm.

  As described above, according to the in-building plant growth system 1 according to the present embodiment, the cultivation room 50, the living room 40, and the outside are ventilated according to temperature changes and carbon dioxide concentrations, and the plants are irradiated. By appropriately changing the amount of solar radiation and the wavelength of light, it is possible to allow plants to grow sufficiently within the building. In addition, since plants can be cultivated in a building, plants can be cultivated regardless of the season, and an urban farm can be realized. In addition to supplying cold air due to the transpiration of plants to the living room 40, maintaining appropriate humidity in the air, and absorbing carbon dioxide in the building by photosynthesis of the plants, The air can be kept easy to spend. Further, since the cultivation room 50 can be viewed from the office, it is possible to construct a moist office environment.

  In addition, this invention is not limited to said embodiment, For example, like the plant growth system 2 in a building shown in FIG. 7, so that the perimeter part 210 of the window of the living room 140 may oppose the outer window 114 A space formed by providing the inner window 128 may be used as the cultivation room 150. The inner window 128 may be configured to be openable and closable on the side of the living room 140 so that the plant can be easily taken in and out of the cultivation room 150.

  According to the above-mentioned plant growth system 2 in the building, a greenhouse can be easily provided in the living room, an empty space can be used effectively, and direct sunlight into the room can be reduced. An increase in indoor temperature due to sunlight can be reduced.
