[LeJohn]

You should not idle a car with the AC on for more than one hour. Prolonged idling with the AC running not only causes certain damage to the vehicle but, more importantly, poses significant health risks to humans. The automobile air conditioning system, commonly referred to as car AC, is designed to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to optimal conditions, providing a comfortable environment for passengers and reducing travel fatigue. It also creates favorable working conditions for the driver, playing a crucial role in ensuring safe driving. The system typically includes cooling, heating, and ventilation components. This integrated setup efficiently utilizes the limited space inside the vehicle, featuring a simple structure and ease of operation.
