Patent ID: 7679879

Claim:
An air conditioning apparatus, comprising: an ion generation portion for generating ions, arranged in a path from an inlet port to an outlet port; a humidifying portion for humidifying air around said ion generation portion, arranged in said path at a position closer to the inlet port than said ion generation portion; an impureness detection portion for detecting impureness of air; a temperature and humidity detection portion detecting temperature and humidity; and a humidified state varying unit for varying a degree of humidification by said humidifying portion in accordance with a degree of impureness detected by said impureness detection portion; wherein said humidified state varying unit increases the degree of humidification of the air around said ion generation portion by said humidifying portion in accordance with the degree of impureness detected by said impureness detection portion when impureness is detected by said impureness detection portion and when the temperature and the humidity detected by said temperature and humidity detection portion attain a prescribed state, and does not vary the degree of humidification of the air around said ion generation portion by said humidifying portion when impureness is not detected by said impureness detection portion even though the temperature and the humidity detected by said temperature and humidity detection portion attain said prescribed state.
