AI Technical Summary
Technical Problem
Calibration accuracy of air sensors in ventilation systems, such as CO2 sensors, deteriorates due to external disturbances caused by sources altering the physical quantity being detected, leading to inaccurate readings.
Method used
A ventilation system with a sensor calibrator that calibrates air sensor readings without the influence of external disturbances by performing calibration during ventilation and termination, ensuring accurate measurements.
Benefits of technology
Improves the accuracy of air sensor calibration by eliminating the impact of external disturbances, thereby maintaining precise detection values.

Abstract
A ventilation system comprises: a ventilation device (3, 200) that ventilates a ventilation space, which is a destination for the ventilation; an air sensor (5, 211) that detects a physical quantity of a detection object in the air of the ventilation space and outputs a detection value corresponding to the detected physical quantity; and a sensor calibrator (100, 211) that performs a calibration against the detection value output by the air sensor. The sensor calibrator calibrates the detection value, which is detected by the air sensor in the ventilation space in a state without a source of change that alters the physical quantity of the detection object, at least once during ventilation and once during ventilation termination by the ventilation device.
