AIR CONDITIONER

To provide an air conditioner that can suppress generation of microorganisms such as fungi in a drain pan without causing deterioration in the drain pan.SOLUTION: An air conditioner includes: a drain pan 17 for receiving condensate water; and a light-emitting part 20 for radiating light toward at least part of the drain pan 17. The light-emitting part 20 radiates light of which total sum of radiation energy in a wavelength band of 440 nm or more and 510 nm or less is larger than total sum of radiation energy in a wavelength band of 440 nm or less.SELECTED DRAWING: Figure 1 【課題】ドレンパンの劣化を招くことなく、ドレンパンにおける菌類等の微生物の発生を抑制できる空気調和機を提供する。【解決手段】この発明に係る空気調和機は、凝縮水を受けるドレンパン１７と、ドレンパン１７の少なくとも一部に向けて光を照射する発光部２０と、を備える。そして、発光部２０が照射する光は、４４０ｎｍ以上５１０ｎｍ以下の波長帯の放射エネルギーの総和が、４４０ｎｍ以下の波長領域の放射エネルギーの総和よりも大きい。【選択図】図１
