Claim 0:
1. An 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 based on indoor environment information and a user-set value, wherein the controller is configured to:
set a rotational speed of the indoor motor and a maximum rotational speed of the outdoor motor based on each of a plurality of user-set operation modes of the air conditioner and
control the indoor motor to rotate at the rotational speed and control the rotational speed of the outdoor motor not to exceed the maximum rotational speed, and wherein the operation mode of the air conditioner comprises a super-low mode, a low mode, an intermediate mode, and a high mode, and wherein the controller is configured to:
when the operation mode of the air conditioner is the super-low mode, set the rotational speed of the indoor motor to rotate the indoor fan at a first indoor fan speed and set the 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, set 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 set 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, set 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 set 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, set 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 set the maximum rotational speed of the outdoor motor to adjust the maximum rotational speed of the outdoor fan to 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.
