Do you need to turn on the AC when using car air conditioning in summer?

[StVictoria]

In summer, turning on the AC switch is definitely necessary when using the car's cold air, otherwise the air conditioning system is just the blower working, delivering air at normal temperature. During hot summers, when the AC button is turned on, the temperature control should be adjusted to the blue position. For automatic air conditioning, a temperature can be set, and then the AUTO button can be pressed, allowing the automatic air conditioning to adjust the interior temperature automatically. Below is some information about car air conditioning AC: 1. The car air conditioning AC is the switch for the compressor, which delivers cold air. The car air conditioning system includes not only the compressor but also the condenser, evaporator, expansion valve, etc. The compressor is one of the most important components of the refrigeration system, responsible for compressing and delivering refrigerant vapor. 2. Generally, you should first turn on the blower, set the air volume to maximum, and start with the external circulation to draw out the hot air inside the car. Then, turn on the AC for cooling. After about two minutes, you can switch to internal circulation, and the car will soon become cool. Once the interior is cool, you can temporarily turn off the AC. If it gets warm again, turn the AC back on. This method of using the air conditioning saves fuel.
