Abstract: An air conditioner and a method for controlling an air conditioner are provided capable of minimizing noise generation. The air conditioner may include an indoor motor configured to drive a fan to blow indoor air and an outdoor motor configured to drive a fan to blow outdoor air. In addition, the air conditioner may include a controller configured to set a rotational speed of the indoor motor to drive a fan to blow indoor air based on operation modes and a maximum rotational speed of the outdoor motor to drive a fan to blow outdoor air and change a rotational speed of the outdoor motor within a range not exceeding the maximum rotational speed based on indoor environment information and a user-set value.

Abstract: An air conditioner is provided, in which a control box is disposed at a boundary between an indoor main body configured to blow indoor air and an outdoor main body configured to blow outdoor air, and the outdoor air may be introduced into the control box. Accordingly, even if it rains, the air conditioner may prevent direct exposure of the control box and/or a heat sink of the control box to rainwater and facilitate heat dissipation of control components disposed in the control box configured to perform inverter control.
