Can You Keep the Air Conditioning On When the Car Is Not Moving?
2 Answers
You should not keep the air conditioning on when the car is not moving. Here are the details about the car air conditioning system: 1. Working Principle: Based on signals from various sensors detecting cabin temperature, evaporator temperature, engine coolant temperature, and other relevant switch signals, the system outputs control signals to manage the operation of components such as the radiator fan, condenser fan, compressor clutch, blower, motor, and air control motor, enabling automatic temperature regulation inside the cabin. 2. Components: The car air conditioning system consists of a refrigeration system, heating system, air purification device, and control system. 3. Function: It adjusts and controls the temperature, humidity, air cleanliness, and airflow inside the cabin to optimal conditions, providing a comfortable environment for passengers and reducing travel fatigue.
I've been driving for over a decade and often encounter situations where I need to keep the air conditioning on while parked. First, ventilation is crucial—running the AC in an enclosed garage for extended periods can lead to dangerous levels of carbon monoxide buildup. Second, battery condition matters; an older car's battery might last less than 30 minutes, while a newer one may hold out for about an hour. If you must wait, keep the air recirculation off, crack a window slightly, and ideally start the engine every 30 minutes to recharge the battery. One summer, I fell asleep in the car and woke up to a dead battery, requiring a jump-start rescue.
