In one embodiment, the artificial light plant 20 may be installed at a height corresponding to one ground level, for example, and the solar plant 10 may be installed at a height corresponding to two stories above the ground. Preferably, the environment (e.g., temperature and / or illumination) of the artificial light plant plant 20 is more easily adapted to the target environment by installing the artificial light plant 20 in the basement and installing the solar plant 10 in the upper layer thereof .

Referring to FIGS. 1 and 2A, the solar plant plant 10 may have the appearance of a general greenhouse or a vinyl house. That is, a wall of a certain height and a roof through which the sun can pass.

FIG. 3 is a diagram for explaining an environmental control system of a hybrid plant plant according to an embodiment, and is a schematic representation of a system configuration for environmental control of a solar plant plant 10 and an artificial plant plant 20. FIG.

In one embodiment, "environmental" control for the photovoltaic plant 10 and the artificial light plant 20 means controlling the temperature and / or illumination of each plant plant 10,20, for example. However, in alternative embodiments, the environmental control may include, for example, humidity control in addition to temperature and illumination, or may involve the adjustment of certain components of the air such as oxygen or carbon dioxide.

Referring to FIG. 3, the hybrid plant 100 includes a solar plant 10 and an artificial plant plant 20 disposed thereunder.

The solar plant plant 10 may include a ventilation window 11, a ventilation fan 13, a temperature sensor 15, and a radiator 19. The ventilation window 11 is installed to be openable and closable so as to ventilate the inside air of the solar plant 10. The ventilation fan 13 can be additionally installed to forcibly ventilate the inside air of the solar plant 10, for example, on the wall surface of the solar plant 10. The radiator 19 is installed to regulate the internal temperature of the solar plant 10.

In one embodiment, the hybrid plant plant 100 further comprises a first blower 17. The first blower 17 is installed so as to communicate between the solar plant plant 10 and the artificial plant plant 20 so as to suck air from the solar plant plant 10 into the plant 20 of the artificial light plant And the like.

The artificial light plant plant 20 may include a plurality of lights 21, a cooling and heating unit 23, and a temperature sensor 25. [ The illumination 21 is for supplying light to the plant to be grown in the artificial light plant 20 and at the same time for raising the temperature inside the artificial light plant 20 due to the heat from the light 21. In one embodiment, the illumination 21 may be selected, for example, from fluorescent lamps, incandescent lamps, LED lighting, etc., and may also be selected to emit wavelengths of a particular band depending on the particular plant species being grown. The cooling / heating unit 23 is for controlling the internal temperature of the artificial light plant unit 20, and may include both a cooling function and a heating function. Alternatively, a cooler and a heater may be separately provided.

In one embodiment, the hybrid plant plant 100 further comprises a second blower 27. The second blower 27 is also installed so as to communicate between the solar plant plant 10 and the artificial plant plant 20 so that the air in the plant 20 of the artificial light plant is sucked into the solar plant plant 10 And the like.

Although not shown, in the preferred embodiment, the hybrid plant plant 100 further includes a control unit. The control unit (not shown) is installed to be electrically connected to or communicable with the above-described components (ventilating fan, temperature sensor, air conditioner, lighting, blower, etc.) of the hybrid plant 100, Can be controlled. For example, the control unit receives the temperature information sensed by the temperature sensors 15 and 25 installed in the plant factories 10 and 20, and controls the ventilation fan 13, the heater 19, the illumination unit 21, ), And the operation of the first and second blowers 17 and 27, respectively.

On the other hand, in an alternative embodiment, the hybrid plant plant 100 may further include a blower to allow the air of the artificial light plant plant 20 to exchange with the outside. For example, a third blower (not shown) for sucking air outside the hybrid type plant and supplying the air to the inside of the artificial light plant 20, and a third blower for blowing air from the artificial light plant 20 to the outside of the hybrid type plant 4 blower (not shown), and the inside air of the artificial light plant plant 20 can be exchanged with the outside as needed by this additional blower.

In the hybrid plant (100) shown in the figure, the solar plant (10) is determined in light and dark (dark) according to the natural days (daytime) and night (nighttime) depending on the presence or absence of the sun. However, the artificial light plant 20 can regulate the name / memorization according to the on / off of the light 21 regardless of the natural day / night, and it is not necessary to be memorized at night and always specified in the daytime.

According to a preferred embodiment of the present invention, the timing of memorization / memorization of the artificial light plant 20 is determined according to the heat transmission load of the artificial light plant 20 and the illumination load of the light 21. That is, irrespective of the natural daytime / nighttime, the date and time of the artificial light plant 20 can be set according to the amount of heat transferred to the outside of the artificial light plant 20 and the degree of heat generated by the light.

4 to 6, the determination of the clear / memorized time according to the heating / cooling load under the specific conditions of the artificial light plant 20 will be described.

4A to 4C are diagrams for explaining cooling / heating load predictive values of an artificial light plant of a hybrid type plant factory according to the first embodiment.

Figs. 4A to 4C are prediction amounts of summer, winter, and spring and autumn, respectively. In this case, a 60W (wattage) fluorescent lamp having a length of 1.2 m is used as the illumination 21.

In the table of FIG. 4, the value of the maximum night heating load is used as the maximum heat transfer load. In general, the maximum night cooling load Qm (unit: kcal / hr) is expressed by the following equation.

Qm = {Ag * (qt + qv) + As * qs} (1 + fw)

(Kcal / m < 2 > hr), qv is the gap ventilation heat transfer load (kcal / m < 2 & ), qs is the surface heat transfer load per unit area (kcal / ㎡ · hr), and fw is the safety factor.

On the other hand, the maximum night cooling load of the above equation may be expressed by the following simplified formula.

Qm = Ag * U * (To - Tc)

Where U is the night cooling load factor (kcal / m < 2 > hr. DEG C), Tc is the cooling set room temperature (DEG C), and To is the design ambient temperature (DEG C), respectively.

In the above equation, the night cooling load factor (U) can be varied depending on the coating method. For example, in the case of a single coating, the coefficient (U) can be set to 1.7, and when it is coated with a single- Can be set. In the embodiment of Figs. 4 to 6, this value is set to 2.0.

Assuming that the covered area of the artificial light plant 20 is 200 m 2, for example, assuming that the daytime outdoor temperature and the nighttime outdoor temperature are 40 ° C. and 30 ° C., respectively, as shown in FIG. 4A, As the internal target temperature, the daytime temperature was set at 25 degrees and the nighttime temperature was set at 10 degrees, respectively, and the value obtained by calculating the maximum night cooling load according to the simplified formula was used as the maximum heat transfer load value in the table of the drawing.

In addition, the figure shows the amount of heat generated by the lighting unit 21 in the table in the drawing, and in consideration of the internal area of the plant 20, a lighting load of approximately 9,288 kcal / hr is obtained when a fluorescent lamp of 4 x 6 columns x 3 rooms is used.

Accordingly, the maximum heat capacity in the table is the sum of the maximum heat transfer load and the illumination load, and the capacity of the cooling / heating unit is determined in proportion to the maximum heat capacity. At this time, the unit of the cooling capacity is represented by RT (refrigerated tone, 3320 Kcal / hr) and the unit of the heating capacity is expressed by KW (kilowatt, 860 Kcal / hr).

As can be seen from the table, the capacity of the cooling and heating apparatus is determined according to the difference between the outside temperature To and the target temperature Tc in the daytime and the nighttime and the lighting load according to the lighting on-off, . In this case, the first case where the day is specified and the night is memorized (indicated by a black letter in the table), the total value of the maximum heat capacity and the second case where the day is memorized and the night is specified ), The sum of the maximum heat capacities is approximately the same, but the first case has a disadvantage that a larger capacity of the air conditioner must be used. Therefore, in order to reduce the facility cost, it is preferable to cool the artificial light plant 20 in the second case, that is, to memorize the day and specify the night.

FIG. 4B shows a case in which the inside condition of the artificial light plant 20 is the same as that in FIG. 4A, and only the outside temperature To of the daytime and nighttime is different. In FIG. 4B, the maximum heat capacity and the capacity of the air conditioner are shown in a first case (indicated by a black letter in the table) in which the day is memorized and the night is memorized 2 (indicated by red letters in the table), the sum of the maximum heat capacities is the same, but in the first case, there is a disadvantage that a larger capacity air conditioner must be used. Therefore, in the second case, So that the artificial light plant 20 is heated.

Likewise, FIG. 4C shows the predicted amount of spring and autumn, which is assumed to be different from the outside temperature To of the daytime and nighttime, and the remaining conditions are the same as in FIG. 4A or FIG. 4B. In this case, It is preferable to cool the artificial light plant 20.

As described above, according to the embodiment of the present invention, the date and time of the artificial light plant factory can be determined based on the maximum heat transfer load to the exterior of the artificial light plant plant 20 and the illumination load of the light 21, , It can be determined according to the maximum capacity of the air conditioner (i. E. Towards the use of a small capacity air conditioner if possible).

5A to 5C are diagrams for explaining the cooling / heating load forecasting amount of an artificial light plant plant of a hybrid plant plant according to the second embodiment. Figs. 5A to 5C are predicted values for summer season, winter season, A case in which a 40 W fluorescent lamp having a length of 1.2 m is used as the illumination 21, and the other conditions are assumed to be the same as in Fig.

As can be seen from Figs. 5A and 5B, in the case of summer and winter, the daytime is memorized and the artificial light plant 20 is cooled (summer season) ) Is preferable. Also, as shown in FIG. 5C, it is desirable to memorize the daytime in the spring and fall and specify the nighttime, but it is preferable to cool the room at the time of memorization, and to heat the room at the specified time.

6A to 6C are diagrams for explaining the cooling / heating load forecasting amount of an artificial light plant of a hybrid plant plant according to the third embodiment. Figs. 6A to 6C are prediction amounts of summer, winter, The LED light source is used as the light source 21, and the remaining conditions are assumed to be the same as in Fig.

Generally, since the amount of heat generated by the LED is small, it can be seen that the illumination load is smaller than the illumination load of the fluorescent lamp. Therefore, as shown in the tables of FIGS. 6A and 6B, in the case of the LED light source, it is preferable to heat the artificial light plant plant 20 (summer season) or to heat the summer plant (winter season) Also, as shown in FIG. 6C, it is preferable to specify the day of the week in spring and to memorize the nighttime, but to cool the nighttime, and to heat the nighttime.

Hereinafter, a method for controlling the environment of a hybrid plant plant according to an embodiment will be described with reference to FIGS. 7 and 8. FIG.

Referring to FIG. 7, the artificial light plant 20 maintains its daytime temperature in the nighttime, and the indoor temperature of the solar plant 10 in summer is about 30 to 40 degrees in the daytime, 25 degrees, and it is assumed that the room temperature of the artificial light plant 20 is maintained at about 25 degrees in the daytime, which is the same as the target temperature, and is maintained at about 10 degrees in the nighttime.

In this environment, the period of changing from day to night, that is, the photovoltaic plant 10 is switched from the famous plant to the memorization, and the artificial light plant 20 is maintained at about 30 to 40 degrees, The photovoltaic plant plant 10 is not only ventilated by the ventilating window 11 or the ventilating fan 13 but also by the blowing of the second ventilator 27 to the air of the artificial light plant 20, The temperature can be dropped by 20 to 25 degrees much faster by being supplied.

The artificial light plant 20 that is maintained at 10 degrees is supplied with air from the solar plant 10 that has been maintained at 30 to 40 degrees in the known art by the blowing of the first blower 17 as well as the light 21 The target temperature of 25 degrees Celsius can be raised much faster. At this time, the temperature rise time can be further reduced by the heating operation of the cooling / heating unit 23 as necessary.

7, the temperature of the artificial light plant 20 is always lower than or similar to the temperature of the solar plant 10, regardless of the specified / memorized period, so that the temperature of the solar plant 10 The indoor air of the artificial light plant 20 can be supplied to the inside of the solar plant 10 by using the second blower 27 in order to adjust the temperature of the plant 20 (for example, to lower the room temperature when the solar heat is very high) .

7, it is assumed that the indoor temperature of the solar plant 10 is about 20 to 30 degrees in the daytime and about 10 to 20 degrees in the nighttime, and the indoor temperature of the artificial light plant 20 is about 25 degrees and maintained at about 10 degrees at night.

In this environment, the period of changing from day to night, that is, the solar photovoltaic plant (10) is converted from the famous plant to the memorization and the artificial light plant (20) is maintained at about 20 to 30 degrees The solar plant plant 10 receives the air of the artificial light plant 20 which has been kept at 10 degrees in the dark by the blowing of the second blower 27 as well as the heater 19, You can drop it much faster. The artificial light plant factory 20 which is maintained at 10 degrees from the memorization supplies the air of the solar plant plant 10 which has been maintained at 20 to 30 degrees from the known plant by the blowing of the first blower 17 as well as the light 21 The target temperature can be raised by 25 degrees. In this case, it is needless to say that the temperature rise time can be further reduced by the heating operation of the cooling / heating unit 23 as necessary.

Likewise, the period of changing from night to day, that is, the period from the solar plant plant 10 to the summer plantation, and the artificial light plant 20 from the summer plant to the memorization, The plant plant 10 receives the air of the artificial light plant 20 which has been kept at 25 degrees in the known temperature by the blowing of the second blower 27 as well as the sunlight and the heater 19, . In addition, the artificial light plant 20, which is maintained at 25 degrees in the known art, receives air from the solar plant 10, which has been kept at about 10 to 20 degrees in the dark by the blowing of the first blower 17, So that the target temperature can be lowered to 10 degrees much faster.

As described above, according to the embodiment of the present invention, the first blower 17 and / or the second blower 27 can be operated at the time of switching between the known plant and the artificial plant plant 20, It is possible to rapidly raise or lower the target temperature by exchanging the air of the lightening plant plant 10 and the air of the artificial light plant 20 by the operation of the heater 10 for raising or lowering the room temperature, And / or even if the air conditioner does not need to be operated or operated, the amount of operation can be reduced by the conventional method, and the energy efficiency is also improved.

FIG. 8 illustrates an apparatus for use in a seasonal cooling / heating mode for each of a solar plant plant and an artificial light plant plant in a hybrid plant plant according to an embodiment of the present invention.

Referring to the drawings, for example, a solar plant plant 10 can be cooled by a ventilation window 11, a ventilation fan 13, and first and second blowers 17 and 27 in summer. Also, in the case of the artificial light plant 20, cooling can be performed by operating at least one of the first and second blowers 17 and 27 while operating the cooling / heating unit 23 in the cooling mode at the time of cooling the artificial light plant plant When the artificial light plant plant is heated, the heating and cooling apparatus 23 can be operated in the heating mode and at the same time, at least one of the first and second blowers 17 and 27 can be operated for heating.

FIG. 9 is a view for explaining the effect of the present invention. In the case of a concrete embodiment for growing strawberry, FIG. 9A is a view for explaining a strawberry cultivation process in a conventional greenhouse, and FIG. This diagram illustrates the process of growing strawberries.

Referring to FIG. 9A, in the case of greenhouse cultivation, seedling cultivation started from March in the nursery in general, and formal cultivation in September, and cultivation was carried out from November to the following year Harvest and harvest until about May. However, in this case, since the temperature becomes higher after March, the sugar content and hardness are lowered, so that the merchantability is lowered, and fresh strawberries can not be supplied after May.

In contrast, referring to FIG. 9B, when a hybrid plant plant according to an embodiment of the present invention is used, seedling cultivation starts in March at a solar plant plant 10 and is completed by August, can do. Thereafter, the strawberry cultivated in the solar plant (10) is transferred to the artificial light plant (20), the new plant is planted in the solar plant (10) and the seedlings are continued. As described above, the artificial light plant (20) can stably maintain the room temperature at 25 degrees Celsius and 10 degrees at the dark place, so that strawberries transferred from the solar plant (10) are harvested continuously for almost one year until March of the following year can do. In other words, year-round production of quality strawberries becomes possible.

Various modifications and variations of the present invention are possible in light of the above teachings. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be determined by the scope of the appended claims, as well as the appended claims.
