Is it okay to leave the parking ventilation on all the time?

[Brielle]

It is not advisable to use the parking air conditioning for too long. It is generally recommended to ventilate every 3-4 hours. Here is an introduction about leaving the parking air conditioning on all the time: 1. Increase the load on the refrigeration system: It is not good for health. You can turn it off first and then turn it on again after a while. 2. Do not sleep in a closed car with the air conditioning on: Because the ventilation in the car is poor, the carbon monoxide emitted by the engine may seep into the car, causing carbon monoxide poisoning. 3. Internal and external circulation switch: When external circulation is used, the air conditioning draws air from outside the car. Internal circulation means the air inside the car is recirculated. Setting the temperature too low can affect your health, so the air conditioning temperature should be adjusted appropriately. The most comfortable temperature for the human body is 20℃ to 25℃. If it exceeds 28℃, people will feel stuffy and hot.
