Can You Get Carbon Monoxide Poisoning by Sleeping in a Car with the Air Conditioning On?
1 Answers
Whether you can get carbon monoxide poisoning by sleeping in a car with the air conditioning on depends on whether you use the internal or external air circulation mode. If you use the internal circulation mode, carbon monoxide emitted by the engine can enter the car through the air conditioning system. With the windows closed, the carbon monoxide concentration inside the car can gradually increase, leading to poisoning. If you use the external circulation mode, which draws air from outside the car, carbon monoxide poisoning is unlikely. However, it is best to leave a small gap in the window when using the air conditioning. Below are the functions of a car air conditioning system: 1. Temperature Control: This is the primary function of car air conditioning. In summer, the cooling system produces cold air to lower the cabin temperature. In winter, except for large commercial vehicles that use independent combustion heaters, most vehicles rely on residual heat from the engine for heating. 2. Humidity Control: Humidity significantly affects passenger comfort. The ideal humidity level inside the cabin should be maintained between 30% and 70%. Standard car air conditioning systems do not regulate humidity; only advanced luxury cars equipped with integrated heating and cooling systems can do so. 3. Airflow Control: The speed and direction of airflow greatly impact comfort. If air is blowing directly, the speed should be limited within a certain range when the temperature is appropriate. The airflow speed can be adjusted based on passengers' living environment, age, health, and temperature preferences. 4. Air Purification: The quality of air inside the cabin is crucial for comfort.
