Abstract

An air conditioner comprised of a humidification unit consumes less energy when operating, the size of the outdoor unit is reduced, and the cost of the air conditioner is reduced. A flow path opening and closing means 82 is provided in a divider 81 that divides a humidification unit 4 from an outdoor air conditioning unit 5 that are in an outdoor unit casing 80. By opening the flow path opening and closing means 82, an absorption flow path is formed that passes through a humidification rotor 58 and discharges air through the front surface of an outdoor fan 29 via an absorption discharge path 75. <IMAGE>
