Can the car cool without turning on the AC?

AC controls the compressor, and it needs to be turned on for cooling. Here are some related details: 1. Modern car air conditioning systems are divided into manual and automatic types. Both manual and automatic air conditioning have an A/C button. Automatic air conditioning only requires setting the desired temperature, and it can automatically select and open or close different air vents, adjust the airflow, and turn the A/C switch on or off based on light sensors and multiple interior temperature sensors to maintain a constant temperature inside the car, ensuring great comfort. With manual air conditioning, you need to adjust the airflow and temperature yourself, and the interior usually does not reach a constant temperature. 2. In hot summer weather, the A/C button should be turned on, which activates the car's compressor to blow cold air. In cold winter, heating has nothing to do with the compressor. The heat source for heating is not obtained from the air conditioning itself but is provided by the car's radiator, which relies on the heat generated by the engine. The blower then blows this heat into the car, consuming almost no energy, so there is no need to turn on the A/C button.
