Description of the Related Art A conventional fine mist cooling device for a cultivation house starts fine mist cooling when a detected indoor temperature becomes higher than an indoor temperature set by an indoor temperature setting dial while operating a ventilation fan. When the fine spray cooling time set by the fine spray cooling timer ends, the fine spray cooling is stopped, and then the fine spray cooling is stopped for the set fine spray cooling pause time set by the fine spray cooling stop timer. It is. A conventional fine mist cooling control device executes fine mist cooling according to a predetermined predetermined fine mist cooling time, and then performs fine mist cooling over a fine mist cooling stop time. Since the humidity fluctuates rapidly due to lack of sunshine and the like, and excessive use of fine mist cooling in the summer in the cultivation house, the fine mist cooling has been a negative factor for the growth of the crop. Therefore, the present invention is to solve such a problem. [0004] In order to solve the above-mentioned problem, the invention of claim 1 is based on the setting of the room temperature set by the room temperature setting dial 15 while operating the ventilation fans 2. When the detected indoor temperature becomes high, the fine mist cooling is started, and when the fine mist cooling time set by the fine mist cooling setting timer 9 ends, the fine mist cooling pause time set by the fine mist cooling stop setting timer 10 is over. In the fine mist cooling device for a cultivation house in which the fine mist cooling is stopped, the humidity is detected by the indoor humidity sensor 13 every predetermined time during the fine mist cooling, and the fine mist cooling is stopped when the detected humidity becomes higher than a predetermined value. It is characterized by. According to the first aspect of the present invention, the control of the fine mist cooling is started while operating the ventilation fans 2,... When the detected temperature of the indoor temperature sensor 11 becomes higher than the set temperature, the fine mist cooling is started. When the set fine air cooling time ends, the fine air cooling is then stopped for the set fine air cooling suspension time. [0006] During the fine mist cooling, the humidity of the indoor humidity sensor 13 is detected at predetermined intervals, and when the detected humidity becomes higher than a predetermined value, control is performed to stop the fine mist cooling. According to the first aspect of the present invention, when the detected humidity becomes higher than the predetermined value during the fine mist cooling, the fine mist cooling is stopped. Adverse effects can be prevented. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cut-away front view of a cultivation house in which the present invention is implemented. Ventilation fans 2 are provided on one side of the cultivation house 1 in the front-rear direction,
An intake port is formed on the other side, and the ventilation fans 2 are operated to generate airflow in the cultivation house 1 and to perform forced ventilation in the room. A light-shielding screen (not shown) is provided on the ceiling of the cultivation house 1 so as to be freely opened and closed. The cultivation gutter 4 is supported on the floor surface of the cultivation house 1 by the columns 3, and the cultivation gutters 4 are arranged on the cultivation gutter 4 through a nutrient solution supply line (not shown). Are supplied to the cultivation beds 5,..., And the drainage discharged from each of the cultivation beds 5,... Is collected in a drainage collection tank (not shown). Below the cultivation floors 5,...
The fine mist pipes 6,... Provided with a large number of spray nozzles for spraying raw water in the form of fine mist are arranged. These fine mist tubes 6, ...
Is supplied with raw water from a fine mist pump 7 through a water supply pipe 7,
Raw water is injected from the injection nozzle toward the airflow flowing in the room, and the air is cooled by heat of vaporization when the fine mist evaporates, so that the room is uniformly cooled. On the input side of the control unit 8, a fine mist cooling setting timer 9 for setting a fine mist cooling time per time, a fine mist cooling cessation setting timer 10 for setting a fine mist cooling pause time per time, An indoor temperature sensor 11 for measuring indoor temperature, an outdoor air temperature sensor 12 installed outside the cultivation house 1, an indoor humidity sensor 13 for measuring indoor humidity, an outdoor air humidity sensor 14 installed outside the cultivation house 1, An indoor temperature setting dial 15 for setting an indoor target temperature and an indoor humidity setting dial 16 for setting an indoor target humidity are connected to each other. Further, on the output side of the control unit 8, a fine mist motor 17 for driving the fine mist pump 7 and fan motors 18,... For driving the ventilation fans 2,. In controlling the fine mist cooling, the operator sets the indoor temperature and humidity with the indoor temperature setting dial 15 and the indoor humidity setting dial 16, and sets the fine mist cooling time per time with the fine mist cooling setting timer 9. When the fine mist cooling pause setting timer 10 sets the fine mist cooling pause time and turns on the ON / OFF switch 20, the fine mist cooling control in the house is started. Then, the ventilation fans 2,... Are driven,
The temperature detected by the indoor temperature sensor 11 is input to the control unit 8,
Next, the detected temperature is compared with the set temperature. If the detected temperature is higher than the set temperature, a start command for fine mist cooling is issued, the fine mist motor 17 is driven, and the nozzles of the fine mist tubes 6,. The fine mist is blown out from the fine mist to start the fine mist cooling. When the fine mist cooling is started, timing of the set fine mist cooling time is started, and when the set fine mist cooling time ends, the fine mist motor 17 is stopped and the fine mist cooling is stopped. Next, time counting of the set fine mist cooling pause time is started, and when the set fine mist cooling pause time ends, fine mist cooling similar to that described above is started. During the suspension of the fine mist cooling, the fine mist cooling is stopped regardless of the temperature. During the fine mist cooling, the detected temperature of the indoor temperature sensor 11 and the detected humidity of the indoor humidity sensor 13 are input to the control unit 8 at predetermined time intervals. Next, the previously detected humidity and the current detected humidity are compared, and when the detected humidity becomes higher than a predetermined value (for example, 20 degrees), control for stopping fine mist cooling is performed. Further, the last detected temperature is compared with the present detected temperature, and when the detected temperature becomes lower than a predetermined value (for example, 5 degrees), the fine mist cooling is stopped. If the amount of fine fog cooling in the cultivation house in summer becomes excessive, the temperature and humidity fluctuate rapidly due to insufficient sunshine and the like, which is a negative factor for the growth of the crop. However, by performing the control as described above, it is possible to prevent the adverse effects on the crop due to the fine mist cooling based on a rapid change in the cultivation environment. In addition, in addition to the above-described fine mist cooling control, a solar radiation amount sensor may be provided in the cultivation house, and a correction control for changing the set fine mist cooling time based on the detection of the sensor may be provided. Thereby, the rapid fluctuation of the temperature and humidity in the cultivation house can be further suppressed. Next, the operation control of the ventilation fans 2 in the cultivation house 1 will be described with reference to FIG. In the cultivation house 1, for example, 5 to 6 ventilation fans 2,... Are installed in each section (for example, 1000 m 2 ), and two temperature / humidity sensors 21 and 21 for operation control are provided in each section. After setting, the operation time is set by a 24-hour timer (not shown), the ON / OFF switch 20 is operated, and the temperature / humidity control is started. Then, the ventilation fans 2,... Are operated during an operation time period set by a 24-hour timer (not shown), and the operation of the ventilation fans 2,. During the suspension time period, the detected temperature and the detected humidity from the two temperature / humidity sensors 21 and 21 are input to the control unit 8, and the detected temperature difference and the detected humidity difference between the two temperature / humidity sensors 21 and 21 respectively. Is calculated. When the detected temperature difference is larger than the predetermined value, the operation of the ventilation fans 2 is started, and
When the detected humidity difference is higher than the predetermined value, the operation of the ventilation fans 2 is started to circulate the wind in the house, and the cultivation environment in the section of the cultivation house is equalized. The conventional operation control of the ventilation fan is performed by manually operating an ON / OFF switch to start operation.
ON / OFF operation is mainly performed by a 4-hour timer, and the content of the operation is determined by the cultivation house manager. Therefore, there is a problem that the cultivation environment fluctuates due to the compartments in the cultivation house, and a uniform cultivation environment cannot be provided to the crop. However, by performing the above-described control, the cultivation environment in the cultivation house can be equalized while reducing the operation cost. Next, the control of the supply of the nutrient solution to the cultivation beds 5,... Will be described. A solar radiation sensor (not shown) and a rain sensor (not shown) are connected to the input side of the control unit so that a nutrient solution supply time zone can be set automatically or artificially.
The integrated amount of solar radiation is calculated from the detection information of the solar radiation sensor and the rain sensor.If the integrated amount of solar radiation is large, the nutrient solution is supplied over the entire supply time period of the nutrient solution, and if the integrated amount of solar radiation is small, In addition, the predetermined time in the latter half of the supply time period of the nutrient solution is changed to the supply unavailable time period, and the supply of the nutrient solution is stopped. By performing such control, it is possible to prevent the cultivation floor from being over-moistened during rain and cloudy, thereby preventing the occurrence of crop diseases and saving fertilizer. In the conventional device, the weather is detected by a solar radiation sensor and a rain sensor, and when it is sunny, a large amount of nutrient solution is supplied according to the amount of solar radiation, and
In the case of cloudiness, a small amount of the nutrient solution was supplied, and the nutrient solution was supplied over the entire supply time zone of the nutrient solution. Therefore, there has been a defect that the supply of the nutrient solution becomes excessive, the disease occurs in the crop, and the fertilizer is wasted. However, in this embodiment, such a problem can be solved. Next, an example of the arrangement of the cultivation floors 5,... On the floor of the cultivation house will be described with reference to FIG. Cultivation house 1
A passage 22 is formed in the center of the floor surface in the front-rear direction.
On both sides of the ridge 2, ridges 23 for cultivating crops in the left-right direction are arranged in parallel at predetermined intervals, and cultivation floors 5 for cultivating crops are placed on the ridges 23,. Hot water pipes 24,... For circulating hot water for heating are arranged in the spaces between the ridges 23,..., And the bent ends 2 of the hot water pipes 24,.
4a are arranged so as to protrude from the left and right sides of the passage 22, and the interval between the bent ends 24a,.
The width is such that the transport vehicle 26 can pass through. Further, between the bent ends 24a,... Of the hot water pipes 24,... On both right and left sides of the passage 22, are formed as inclined surfaces 25,. The cultivation floors 5,... Are arranged on the inclined surfaces 25,. Thus, a large number of cultivation floors 5,... Can be arranged in the cultivation house, and there is no accumulation of water in the passage 22, and the traveling of the transport vehicle 26 can be made safe. Next, another embodiment of the transport vehicle 26 will be described with reference to FIG.
