Abstract (en)

To provide an outdoor unit of an air conditioner that can suppress the blowing noise of a fan without lowering operating efficiency. An outdoor unit (2) is disposed with an outdoor heat exchanger (13), an outdoor fan (29) and a controller (4). The outdoor heat exchanger (13) performs heat exchange with air as an evaporator during heating operation. The outdoor fan (29) generates an air flow that passes a surface of the outdoor heat exchanger (13). The controller (4) performs in-frost fan control for lowering the rotational speed of the outdoor fan (29) when frost formation on the outdoor heat exchanger (13) is detected or estimated.
