Air conditioner temperature connection ...

Friends, I noticed something when the temperature of my car was normal 90, when I turn on the air conditioner, the temperature drops below 90. Do they have a connection with each other or am I misinterpreting ...

The air conditioner runs fan continuously and the temperature decreases during idling or quiet use. However, due to the fact that the fan gets cooler because the fan gets cooler due to the fact that the air conditioner loads the engine on the stop or ramps in the city, the temperature stops again at 90. It can even go over 90.
