Abstract: The function of an air conditioner is to meet the user's comfort requirements for the indoor environment by adjusting the indoor temperature and humidity to meet the set standards. At present, there is a significant deviation in the temperature sensor detection value of the one to many air conditioners on the market, which leads to some indoor unit automatically turning off when the hot running temperature reaches the desired temperature. After the room temperature drops, the air conditioner cannot start, reducing user comfort. Conducts in-depth research on this issue, analyzes the reasons for environmental temperature detection deviation, proposes improvement measures for sensor installation position, and conducts experimental verification. The results indicate that the sensor located on the right side of the air conditioner far from the coil can reduce interference in temperature detection, and the air conditioner can start normally after the room temperature drops, improving user comfort.
