To suitably suppress noise generated by an air conditioner.SOLUTION: An air conditioner 1 air-conditions an object space 2, and comprises a flow passage 10, one or a plurality of blowout ports 12-14, a fan 20, a low-frequency reduction part 30, and a high-frequency reduction part 40. The one or plurality of blowout ports link the flow passage to the object space. The fan makes air flow down toward the one or plurality of blowout ports respectively through the flow passage. The low-frequency reduction outputs a low-frequency control sound from a low-frequency speaker provided nearby the fan in the flow passage so as to reduce low-frequency noise. The high-frequency reduction part outputs a high-frequency control sound from a high-frequency speaker provided downstream from the fan in the flow passage so as to reduce high-frequency noise.SELECTED DRAWING: Figure 1

    【課題】空調装置により生じる騒音を好適に抑制する。【解決手段】空調装置1は、対象空間2の空調を行い、流路10と、1又は複数の吹出口12〜14と、ファン20と、低周波低減部30と、高周波低減部40と、を備える。1又は複数の吹出口は、流路と対象空間とを連通させる。また、ファンは、流路において、1又は複数の吹出口の各々に向けて空気を流下させる。また、低周波低減部は、流路におけるファンの付近に設けられた低周波スピーカから低周波制御音を出力することで、低周波の騒音を低減させる。また、高周波低減部は、流路において、流路におけるファンの下流側に設けられた高周波スピーカから高周波制御音を出力することで、高周波の騒音を低減させる。【選択図】図1
