Air conditioner outdoor unit

摘要

Provided is an air-conditioner outdoor unit which is made compact by having the unit height thereof reduced, which exhibits excellent maintenance properties, and with which a sufficient adsorption air flow for a humidification rotor is ensured. A humidification rotor (63) includes: a moisture-adsorption area (61) where moisture in external air is adsorbed; and a moisture-release area (62) where the moisture adsorbed in the moisture-adsorption area (61) is released by being heated. The plate-shaped humidification rotor (63) is installed along a plane orthogonal to a front-rear direction. In an air passage, an air current flows from a downstream side of an outdoor fan (39) to the moisture-adsorption area (61) of the humidification rotor (63).
