Why does the engine sound louder when the air conditioning is turned on?

[DeSadie]

Because the compressor starts working, the engine load increases, and the engine must increase its speed to compensate for the power demand. Here is the relevant introduction: 1. Function: The car air conditioning refers to the air conditioning device installed in the car, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. 2. Structure: The car air conditioning generally includes a cooling device, a heating device, and a ventilation device. This combined system makes full use of the limited space inside the car, has a relatively simple structure, and is easy to operate, making it a popular modern car air conditioning system internationally.
