Is it okay to keep the car air conditioning on for a long time?

[StEmily]

It is not advisable to keep the car air conditioning on for a long time. Here are the relevant explanations: 1. Impact on the human body: If the vehicle is driven with the air conditioning in recirculation mode for a long time, the oxygen content in the car will decrease, which may cause symptoms such as dizziness and nausea for the occupants. Therefore, if the air conditioning is used for a long time, it is best to switch between recirculation and fresh air modes to maintain air freshness inside the car. Additionally, if the air conditioning temperature is too low and the outside temperature is too high, the sudden change in temperature can easily cause colds for people with poor physical condition. 2. Impact on the vehicle: Although the power source of the air conditioning system is provided by the engine, the working power of the air conditioning cooling fan is driven by the battery. When the vehicle is idling, the electricity generated to charge the battery cannot keep up with the consumption, which may lead to battery depletion and damage its lifespan over time. Moreover, idling with the air conditioning on for a long time may also affect fuel consumption and increase engine carbon deposits.
