Claim 8:
9. A method for controlling an air conditioner, the air conditioner comprising a base, an indoor fan disposed on the base and configured to blow indoor air, an indoor motor disposed on the base and configured to drive the indoor fan, an outdoor fan disposed on the base and configured to blow outdoor air, an outdoor motor disposed on the base and configured to drive the outdoor fan, and a controller configured to control the indoor motor and the outdoor motor, the method comprising:
determining, by the controller, a user-set operation mode of the air conditioner;
setting, by the controller, a rotational speed of the indoor motor and a maximum rotational speed of the outdoor motor based on each of the operation modes of the air conditioner; and
controlling, by the controller, the indoor motor to rotate at the rotational speed, changing a rotational speed of the outdoor motor based on indoor environment information and a user-set value and controlling the rotational speed of the outdoor motor not to exceed the maximum rotational speed, and wherein the setting comprises:
when the operation mode of the air conditioner comprising a super-low mode, a low mode, an intermediate mode, and a high node is the super-low mode, setting the rotational speed of the indoor motor to rotate the indoor fan at a first indoor fan speed and setting a maximum rotational speed of the outdoor motor to adjust a maximum rotational speed of the outdoor fan to be a first outdoor fan speed;
when the operation mode of the air conditioner is the low mode, setting the rotational speed of the indoor motor to rotate the indoor fan at a second indoor fan speed, which is greater than the first indoor fan speed, and setting the maximum rotational speed of the outdoor motor to adjust the maximum rotational speed of the outdoor fan to be a second outdoor fan speed, which is greater than the first outdoor fan speed;
when the operation mode of the air conditioner is the intermediate mode, setting the rotational speed of the indoor motor to rotate the indoor fan at a third indoor fan speed, which is greater than the second indoor fan speed, and setting the maximum rotational speed of the outdoor motor to adjust the maximum rotational speed of the outdoor fan to be a third outdoor fan speed, which is greater than the second outdoor fan speed; and
when the operation mode of the air conditioner is the high mode, setting the rotational speed of the indoor motor to rotate the indoor fan at a fourth indoor fan speed, which is greater than the third indoor fan speed, and setting the maximum rotational speed of the outdoor motor to adjust the maximum rotational speed of the outdoor fan to be a fourth outdoor fan speed, which is greater than the third outdoor fan speed, and wherein the first indoor fan speed is greater than the first outdoor fan speed, the second indoor fan speed is the same as the second outdoor fan speed, the third indoor fan speed is less than the third outdoor fan speed, and the fourth indoor fan speed is less than the fourth outdoor fan speed.
