Air-conditioner outdoor unit

摘要

An air-conditioner outdoor unit (30) is provided with: a casing (40) having an interior thereof divided into an air blower chamber and a machine chamber which are arranged on the left and the right respectively; a compressor (31) disposed in the machine chamber; an outdoor heat exchanger (33) disposed in the air blower chamber; an outdoor fan (39) disposed in the air blower chamber; and a humidification unit (60) provided with a plate-shaped humidification rotor (63). The outdoor fan (39) passes external air through the outdoor heat exchanger (33). The humidification rotor (63) includes: a moisture-adsorption area (63a) where moisture in the external air is adsorbed; and a moisture-desorption area (63b) where the moisture adsorbed in the moisture-adsorption area (63a) is desorbed by being heated. The humidification rotor (63) is provided further towards a front, along a vertical plane, than the outdoor heat exchanger (33). The humidification rotor (63) is disposed such that the moisture-adsorption area (63a) is positioned in the air blower chamber, and the moisture-desorption area (63b) is positioned in the machine chamber. Furthermore, the entirety of a rotor drive motor for rotationally driving the humidification rotor (63) is disposed in the machine chamber.
