Abstract
A carbon dioxide sensor (92) measures the carbon dioxide concentration of inside air. An inside air control system (30) controls the carbon dioxide concentration of the inside air based on a measured value obtained by the carbon dioxide sensor (92). If the measured value obtained by the carbon dioxide sensor (92) returns to a predetermined normal range after falling outside the normal range, the controller (110) of the inside air control system (30) performs a determination operation. The determination operation is an operation for supplying outdoor air to the carbon dioxide sensor (92) to determine whether or not the carbon dioxide sensor (92) is normal.
Claims9
An inside air control system comprising:
- a gas sensor (92) configured to measure a concentration of a target gas contained in inside air in a storage (1),
- the inside air control system performing a concentration control operation to control the concentration of the target gas in the inside air based on a measured value obtained by the gas sensor (92),
- the inside air control system further comprising:
- an outdoor air supply passage (255, 281) through which outdoor air is to be supplied to the gas sensor (92);
- and
- a controller (110) configured to perform a determination operation if the measured value obtained by the gas sensor (92) returns to a predetermined normal range after falling outside the normal range, the determination operation being performed to supply outdoor air through the outdoor air supply passage (255, 281) to the gas sensor (92) to determine whether or not the gas sensor (92) is normal.
