INDOOR VENTILATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an indoor ventilation system capable of efficiently exhausting chemical substances such as formaldehyde while suppressing wasteful energy consumption. SOLUTION: The integrated amount of ventilation which is obtained by integrating the amount of ventilation per unit time from the start of the operation of a ventilation means 1 is calculated, and the ventilation means 1 is controlled by a controller 5 so as to reduce the amount of ventilation of the ventilation means 1 as the integrated amount of ventilation is increased. The amount of ventilation is determined based on the integrated amount of ventilation and history information on the room temperature (for example, the average room temperature) from the start of the operation of the ventilation means 1.
