What does maxac and ac air conditioning mean?

[DiJosephine]

maxac is the maximum cooling mode of the air conditioning, and ac is the switch for the car air conditioning cooling mode. Once turned on, the air conditioning can cool. Below are the relevant explanations: 1. The cooling principle of car air conditioning is that after pressing the ac button, the compressor clutch will engage, and the engine will drive the compressor to operate. The compressor continuously compresses the refrigerant and delivers it to the evaporator. The refrigerant can cool the evaporator, and the evaporator can cool the air blown by the blower, so the air conditioning vents can blow out cold air. 2. The heating principle of the air conditioning is that when the heating function is turned on, there is no need to press the ac button, and the compressor does not need to operate when using the heating. When the air conditioning is heating, the high-temperature coolant from the engine flows through the heater core, and then the air blown by the blower passes through the heater core, so the air conditioning vents can blow out warm air.
