Abstract: In the process of using air conditioning, users often feel uncomfortable when the indoor temperature reaches the set temperature and the prototype still runs. What is the reason that will affect the shutdown of the air conditioner when it reaches the temperature? In order to study this problem and make users experience well, it makes an experimental analysis and research on reaching temperature shutdown. Through comparative tests, the effects of frequency reduction speed and time, frequency shielding control anti fluctuation time and heat leakage on reaching temperature shutdown are analyzed. The results show that under the condition of setting the temperature desired by the user, changing the low-frequency residence point frequency can effectively shorten the time to reach the lowest frequency, avoid the continuous heat output caused by the long reaction time of the prototype after the environment reaches the temperature, make the user feel uncomfortable and accelerate the response time of reaching the temperature and shutdown.
