Introduction of outside air is started after a person is not detected. A CO2 concentration, which is acquired when a preset first waiting time elapses, is set as a provisional reference value. The carbon dioxide concentration, which is acquired when a preset second waiting time elapses, is compared with the provisional reference value. In a case where a change rate of the carbon dioxide concentration is out of a preset allowable range, the carbon dioxide concentration is acquired when the second waiting time elapses after newly setting the acquired carbon dioxide concentration as the provisional reference value. In a case where the change rate of the carbon dioxide concentration is in the allowable range, the currently set provisional reference value is set as the reference value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"CO2 sensor reference value calibration apparatus and method for calibrating reference value of CO2 sensor","description":"A controller as a CO2 sensor reference value calibration apparatus calibrates a reference value of the CO2 sensor in the following manner.
