ることができる。First, conditioned air is blown into the work chamber 20 from the air outlet 40, and at the same time, it is sucked in from the gas air intake 24 containing carbon dioxide gas discharged from the workers 22,22. Next, the sucked carbon dioxide gas is sent into the duct 14 via the duct 18. When the carbon dioxide gas is sent into the duct 14, the carbon dioxide concentration detector 38 detects the carbon dioxide concentration in the gas. Upon detection, the detected information is transmitted to the control device 34 via the cable 36. The control device 34 calculates the carbon dioxide concentration based on the transmitted information, and sends a signal to open the control valve 28 via the cable 32 if the calculated carbon dioxide concentration is 800 ppm or less. Send. As a result, highly concentrated carbon dioxide gas is passed from the carbon dioxide cylinder 30 to the duct 14 via the duct 26.
sent to. Therefore, the carbon dioxide gas from the work chamber 20 and the carbon dioxide gas from the carbon dioxide cylinder 30 are mixed. Then, the concentration of the mixed carbon dioxide gas is detected again by the carbon dioxide concentration detector 38. When the detected carbon dioxide concentration is higher than the sooppm, the control device 34 transmits a signal to open and close the control valve 28 in a predetermined manner. This allows the concentration of carbon dioxide supplied to the plant cultivation room 10 to be reduced to 12.12
It can be uniformly supplied at 800 ppm, which is suitable for the cultivation of...
