[0002] As we all know, when using an air conditioner, the user sets the target temperature through a remote control or human-computer interaction tool such as an APP. The air conditioner operates by controlling loads such as the compressor and fan to make the indoor ambient temperature reach the set target temperature expected by the user.

[0003] The current technical solution used by air conditioners is to detect the indoor ambient temperature and compare it with the set target temperature, and control the frequency, fan and other aspects according to the difference to achieve the set target temperature. In the existing technical solution, the sensor used to measure the indoor ambient temperature is usually installed in the indoor unit of the air conditioner, but for wall-mounted air conditioners, it is generally installed at a higher position from the ground, and the user's activity range is in the room. In this case, the temperature sensor is far away from the user, which will cause a deviation between the detected indoor ambient temperature and the indoor ambient temperature perceived by the user. If the operating state of the air conditioner is controlled based on the detected indoor ambient temperature, the temperature will deviate from the user's expectations, affecting the user's comfort when using the air conditioner.
