PROBLEM TO BE SOLVED: To perform appropriate humidification even if a surrounding ambient temperature is low. SOLUTION: It is judged which of setting temperature regions being stored in advance a detection temperature by a temperature detection means corresponds to. A correction temperature is obtained by correcting the detection humidity by the humidity detection means according to the setting temperature region concerned, or the setting moisture is increased. Then, the amount of humidification is adjusted so that the correction humidity or the detection humidity becomes the setting humidity. |
