AIR-CONDITIONER OUTDOOR UNIT

摘要

An air-conditioning outdoor unit (30) comprises a casing (40) of which the interior is divided into an air-blower chamber and a machinery chamber aligned laterally, a compressor (31) disposed in the machinery chamber, an outdoor heat exchanger (33) disposed in the air-blower chamber, an outdoor fan (39) disposed in the air-blower chamber, and a humidifying unit (60) having a tabular humidifying rotor (63). The outdoor fan (39) passes outdoor air through the outdoor heat exchanger (33). The humidifying rotor (63) includes a moisture-adsorption area (63a) for adsorbing moisture in the outdoor air and a moisture-releasing area (63b) for releasing the moisture adsorbed in the moisture-adsorption area (63a) when heat is applied. The humidifying rotor (63) is set up in front of the outdoor heat exchanger (33) along a vertical plane. The humidifying rotor (63) is disposed so that the moisture-adsorption area (63a) is positioned in the air-blower chamber and the moisture-releasing area (63b) is positioned in the machinery chamber. The entirety of a rotor-driving motor for rotatably driving the humidifying rotor (63) is disposed in the machinery chamber.
