Why is the carbon monoxide detector the guardian of life safety in the car ?

Let's take an example: the experimenter parked a small car in the paint booth of the car dealership, turned on the car air conditioner and kept the external circulation state, closed the doors and windows of the car, and used a carbon monoxide alarm car detector to detect the carbon monoxide content in the car at different times.

The test results are as follows:
0 minutes, the carbon monoxide concentration in the car is 0ppm, the temperature in the car is about 20℃, and it feels comfortable;
For 1 minute, the carbon monoxide concentration in the car is 5ppm;
After 3 minutes, the warning light of the carbon monoxide alarm car detector starts to flash;
For 5 minutes, the carbon monoxide concentration in the car is 65ppm, and the warning light of the detector keeps flashing and vibrating;
15 minutes, the carbon monoxide concentration in the car is 70ppm, the warning light of the carbon monoxide alarm car detector keeps flashing and vibrating;
In 25 minutes, the carbon monoxide concentration in the car was 91ppm, and the warning light of the carbon monoxide alarm car detector kept flashing to give an alarm. There is obvious suffocation when entering the paint room, and obvious discomfort after entering the car for 1 minute.

It can be seen that in a closed garage, a car with an air conditioner will produce a large amount of carbon monoxide. In just over 20 minutes, the concentration of carbon monoxide exceeds the standard seriously, and there is an obvious feeling of suffocation. Therefore, we warmly remind car owners to be vigilant when turning on the air conditioner, and try not to sleep in a closed car with the air conditioner on, so as to avoid unnecessary casualties! Cherish life and stay away from carbon monoxide! A carbon monoxide alarm car detector, a must in the car!
