What are the effects of turning on the cold air without AC?

[VonLogan]

If the car turns on the cold air mode without activating the AC, the cooling effect will not reach the optimal expectation. The AC switch controls the compressor, which is one of the main components of the car's air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. The usage method of car AC is as follows: 1. In hot summer, when turning on the AC button, you need to adjust the temperature to the blue position. For automatic air conditioning, you can set a temperature and then press the auto button. The automatic air conditioning will adjust the interior temperature based on the external and internal temperatures. 2. Direct the air vents slightly upward, utilizing the principle that hot air rises and cold air sinks. As the cold air descends, it can quickly cool the interior. Also, avoid placing decorations in front of the air vents as they may affect the cooling efficiency.
