Should the car air conditioning AC be turned off or on in summer?

[PaisleeRose]

In summer, when using the air conditioning, the AC button should be turned on. The AC button is the cooling switch for the car's air conditioning system. If the AC button is not pressed, the air conditioning will not cool. Here is some related information about car air conditioning: 1. In hot summer, when the AC button is turned on, the temperature control should be adjusted to the blue position. For automatic air conditioning, you can set a temperature and then press the AUTO button, and the automatic air conditioning will adjust the interior temperature accordingly. 2. The car air conditioning AC is the switch for the compressor. The car air conditioning system includes not only the compressor but also the condenser, evaporator, expansion valve, etc., which work together to compress and transport refrigerant vapor.
