PURPOSE:To improve not only the quality of dwelling space, but also comfortable feeling by a method wherein a fluctuation period of an air blowing fan and an odor injection pitch are operated at the same period. CONSTITUTION:When an air conditioner 1 is started, circulation air passes through a filter 2 and its temperature and humidity are adjusted by a coil 3, thereafter the air is sent into an office space by a blower fan 4. The blower fan 4 repeats a variation of fluctuation of 1/f at a specified period through an inverter panel 5 according to a program in a control device 12. In turn, as a specified point of the fluctuation air blowing of 1/f of the blower fan 4, for example, a time when the amount of blown air becomes maximum is detected by a sensing means, the control device 12 opens an injection control valve 11 for a specified period of time and atomizes odor in a liquid odor bomb 8 into an air flow passage through an injection nozzle 10. |
