PROBLEM TO BE SOLVED: To solve problems found in a case when a ventilation device and a deodorization device for circulating ion indoors are combined and independently operated, that ion is discharged outdoors due to deodorization during a ventilating operation, and the deodorization is not implemented in stop of the ventilation in which deodorization effect is expected.SOLUTION: As a ventilation device 1 and a deodorization device 3 disposed indoors, are constituted so that the deodorization device 3 is stopped in operating the ventilation device 1, and the deodorization device 3 is operated in stopping the ventilation device 1, indoor deodorization can be efficiently and surely implemented.SELECTED DRAWING: Figure 3 |
