Conventionally, in greenhouses, hot water heated by a boiler is passed through hot water pipes installed inside the greenhouse, and the temperature inside the greenhouse is maintained at around 24°C through the hot water in the hot water pipes. Warm air rises near the ceiling due to convection, and at a height of 300% from the soil surface, there is a temperature difference of around 3 to 4 degrees Celsius compared to near the ceiling, and on the west side of the greenhouse,
Due to the influence of the western sun, temperatures were around 3°C higher than those on the east side, and this caused large variations in the growth of crops depending on their location within the greenhouse.

On the other hand, depending on the crop, the sugar content of the crop is likely to be affected by too much or too little humidity, and if it is too humid, the crop will become watery.

Conventionally, therefore, a separate carbon dioxide gas generator was installed inside the greenhouse to supply carbon dioxide gas, but since carbon dioxide gas has a higher specific gravity than air, it stagnates in the lower part of the greenhouse, producing crops. There is a drawback that the leaves are not spread evenly.

Conventionally, a fan similar to a general electric fan is installed inside the greenhouse, and this fan agitates the air in the greenhouse to solve the above problem. This caused inconveniences such as strong winds hitting the crops at that location or in the vicinity, causing them to dry out and eventually wither, resulting in insufficient results.

In addition, when the greenhouse 1 building extends from east to west, if the temperature on the west side rises due to the influence of the setting sun, close the air volume adjustment valve 17 on the east side and open only the air volume adjustment valve 1B on the west side. If you stir the air and replace it with the east side, you will have greenhouse 1.
The temperature inside can always be kept constant.

In this way, the present invention divides a suction chamber and a discharge chamber along the longitudinal direction ζ in a duct suspended from one end of a greenhouse to the other, and divides the suction side of the blower into the suction chamber and the discharge side of the same. A discharge chamber ζ is provided in communication with each other, several air intake ports are provided on the outer wall of the suction chamber, several air outlets are provided on the outer wall of the discharge chamber, and the discharge chamber of the duct is connected to the suction chamber. Since the volume is larger, the blower of the blower is driven to forcefully draw in the air inside the greenhouse while allowing it to flow out slowly, allowing air to flow throughout the greenhouse without creating a sudden outflow of air inside the greenhouse. As a result, the temperature in each part of the greenhouse can be made uniform, and the inconvenience of partially drying out the crops does not occur, thereby preventing the crops from dying.

In addition, a dehumidifier is installed on the discharge side of the blower, and when there is too much humidity in the intake air, it is dehumidified and discharged outside the duct, so the effects of high humidity on crops are also eliminated, and if necessary, carbon dioxide gas By being able to compensate for the deficiencies, it is easy to maintain the conditions that are problematic in greenhouse cultivation, such as temperature, humidity, amount of carbon dioxide, breeze, etc., to the same conditions as in natural cultivation, and greenhouse cultivation can be made to the same level as natural cultivation. There are excellent effects that can be done.
