Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an indoor unit of an air conditioner and a control method thereof. Background technique [0002] At present, the air outlet method of the split floor air conditioner is generally the air outlet from the upper part. When in use, there is a problem that the upper air volume is very large, and the air is basically not blown near the ground. Especially when heating, the comfort is relatively poor. , it is difficult to achieve uniform air volume and temperature in the room. [0003] In order to improve the comfort of the air conditioner, some air conditioners adopt the air outlet method that can discharge air up and down. This air conditioner has two air outlets up and down and fan parts that supply air to the two outlets respectively.
