Is the AC light on for cold air or hot air?
1 Answers
The AC light on indicates cold air, because when the AC function is activated, the air conditioning compressor starts working. AC is short for Air Condition, which translates to air control and air conditioning in Chinese. In a car, it can be understood as the air conditioning cooling switch. When the AC light is on, the air conditioning compressor starts, increasing the engine load and consequently fuel consumption. Besides cooling, the air conditioning compressor also serves to dehumidify. Turning on the AC button helps maintain a dry interior, preventing fogging on the car windows and keeping the temperature inside the car constant.
