A control device repeats first air volume control and second air volume control for a predetermined number of times irrespective of a control state at that time while forcedly driving an ion generator, when a bacteria elimination shower switch is turned on. In the first air volume control, a sirocco fan generates an air flow having a predetermined air volume. In the second air volume control, the sirocco fan generates an air flow having an air volume smaller than the predetermined air volume. Therefore, a bacteria elimination effect is enhanced in an air conditioning apparatus.
