A man in Longhai died in a car, suspected of sleeping with the air conditioner on. What do you think?

Sleeping with the air conditioner on in the car can cause death. You must know some common sense about air conditioning in the car.

Under the scorching sun, the temperature inside a car without air conditioning can reach 80 degrees. When you open the door, every trace of air is filled with "heat". If you get in the car at this time, it will feel like you are in a furnace. At this time, car air conditioning is very important.

Here I would like to share with you the use of air conditioning

1. Open the window to let some air in before getting in the car

If the car is parked under the scorching sun for a long time , Do not use the air conditioner immediately after starting the vehicle.

First open all the windows for ventilation, start the external circulation, and exhaust the hot air. After the temperature inside the car drops, close the windows and turn on the air conditioner. If you directly enter the car and turn on the internal circulation of the air conditioner, the overheated air directly entering the circulation system will cause great damage to the compressor.

In addition, do not turn the air conditioner on and off frequently to prevent damage to the air conditioning system.

2. Do not adjust the direction of the air conditioner outlet at will.

Some car owners do not pay attention to adjusting the direction of the air conditioner when using the air conditioner, which is not conducive to the best effect of the air conditioner. According to the principle that cold air sinks and hot air rises, the correct approach should be to turn the air outlet upward when turning on the air conditioner and downward when turning on the heating.

3. Do not use the air conditioner for too long each time

Some car owners often turn on the air conditioner after getting in the car. Using the air conditioner for a long time will cause excessive pressure on the condenser, which will It will cause losses to the refrigeration system, so you should not use the air conditioner for too long each time. If the temperature in the car has reached a comfortable temperature, you can turn off the air conditioner and turn it on again after a while.

4. It is not advisable to use the internal circulation of the air conditioner for a long time

Because the internal circulation is the circulation of air in a closed space in the car, the oxygen content in the car will continue to decrease, and if the cylinder The gasoline in the car is not completely burned, and the unburned carbon monoxide in the engine may also leak into the car. Therefore, the air quality in the car will become worse and worse, and even cause harm to the human body. Therefore, the internal circulation should be turned on for a while, and the outer circulation should be turned on for a while to let fresh air enter the car. This is why you cannot sleep in a car with the internal circulation on.

5. Develop a good habit of turning off the air conditioner first and then turning off the engine when parking.

Some car owners often think of turning off the air conditioner only after turning off the engine. This is harmful to the engine because it will The next time the vehicle is started, the engine will start with the load of the air conditioner. Such a high load will damage the engine. Therefore, you should turn off the air conditioner before turning off the engine every time you park the car. You should also wait two or three minutes after starting the vehicle and the engine is lubricated before turning on the air conditioner.

6. Do not smoke in the car

Some people turn on the air conditioner and light a cigarette when they stop to rest or wait for someone in the car, which is very comfortable. But doing so is harmful to health, because the doors and windows are closed and the smoke cannot be discharged at once, which will naturally irritate your eyes and respiratory system.

If you have a "smoking addiction", you will definitely feel very uncomfortable if you don't smoke at this time. But adjust the air conditioning ventilation control to the "exhaust" position. At this time, the smoke in the car can be smoothly discharged out of the car.

7. Do not stack items near the air inlet

Some people are used to making the car very messy, such as stacking various items near the air inlet, which seems to be Random actions are actually very bad. Doing so will block the air inlet and hinder the air circulation of the air conditioning system. Some people will complain that the air conditioner is still not cool, so go check to see if the air inlet is blocked.

8. Turn off the air conditioner and then turn it off

Turn on the air conditioner, hum a little tune, and feel very comfortable along the way. When you reach the destination, turn off the engine, and then you remember or cannot remember whether the air conditioner is on or off. close. Doing so will cause mold due to moisture to multiply in the air conditioner. When you start your car the next day, it will ignite with the pressure of starting the air conditioner. The high load brought by this will also cause damage to the engine.

9. The air conditioner cannot always be turned on in the low gear.

When turning on the air conditioner in the car, it is generally not turned on to the maximum gear. I think it wastes fuel and the fan makes too much noise. , which sounds upsetting. But if you never drive to the maximum gear, you will also get sick.

Why? When the air conditioner is in use, it will suck in a lot of dust to form dirt, which will cause mildew over time. It will be dispersed into the car through the air conditioner, and people in the car will inhale it into their bodies. Therefore, you should always turn the air conditioner to the maximum gear and use a strong The most scientific way is to blow out the dirt in the air conditioner with strong wind.

Cars are very common in today’s society. I hope everyone will pay more attention to some safety tips when using them.

It is regrettable and heartbreaking to see such a thing.

When the car is turned on with the air conditioner, the carbon monoxide produced by the idling engine will be drawn into the car by the exhaust fan when the ventilation is poor, causing human poisoning. If the car windows are closed, When the internal circulation is turned on, the car will be occupied by carbon dioxide exhaled by the human body, causing the oxygen to be thin. Sleeping people will inhale toxic gases and enter a coma without knowing it. If the time is longer, it will be life-threatening.

It can be seen that if you are tired and want to rest in the car, internal circulation and external circulation are very easy to cause danger. Don’t take chances and think that it will be fine if you only sleep for a few minutes. Unexpectedly, once you fall asleep, you will Why is it that you can control it yourself?

The best way is not to drive fatigued or fall asleep in the car. There are special service area rest rooms on highways. If you must sleep in the car, remember to leave 8-10 cm of windows. Gaps to keep air flowing!

I hope the tragedy will never happen again!

With the rapid development of the automobile industry, air conditioning, which used to be a luxury product, is now basically standard equipment in cars. Although air conditioning brings a comfortable driving experience to everyone, it must be remembered that You cannot sleep in a car with the air conditioner on, as you may never wake up from your sleep.

In recent years, there have been a few cases of deaths caused by sleeping in cars with the air conditioner turned on

Case 1: Building 5, a commercial building south of Chengnan Primary School, Jiangyin City, Jiangsu Province on August 15, 2012 A man and a woman were found dead in a car in a garage. The two died of carbon monoxide poisoning. The two are not a couple.

Case 2: In 2013, a man and a woman died in a garage in a community in Pingyuan County, Shandong Province, sleeping overnight in the car with the air conditioner turned on. Neighbors nearby revealed that the gas tank had been exhausted when they were discovered. The police later investigated that the death was caused by carbon monoxide poisoning.

Case 3: On the evening of June 25, 2013, a tragedy occurred in the underground garage of Xiaoran Renjia Community in Xiaoshan District, Hangzhou City. A man and a woman were unconscious in the car. They were found and sent to the hospital for rescue. Very soon Almost two people were pronounced dead. After the incident, the police from the police station and Xiaoshan criminal police rushed to the scene one after another and determined that it was carbon monoxide poisoning;

Case 4: In 2013, a man and a woman died naked in a car in a community in Hexi, Changsha. The man had been killed when the incident occurred. The wife searched all night and finally found her in the garage. When she opened the car door, she was immediately stunned by the naked death of both men and women in front of her. It turned out that the man and his mistress had an affair in the car, and they died of excessive passion while playing with the car in the garage that was closed on all sides.

In fact, there are many cases of poisoning and suffocation due to poisoning and suffocation when air conditioners are turned on in cars at home and abroad. This also shows that many driver friends have little safety awareness and do not know much about the normal use of air conditioners. So how is carbon monoxide produced in the car?

Some professionals have conducted simulation experiments. The experimenter parked a small car in the paint room of the car dealership, turned on the car air conditioner and maintained external circulation, closed the doors and windows, and used a carbon monoxide detector to detect the carbon monoxide content in the car at different times.

Test results: 0 minutes, the carbon monoxide concentration in the car is 0ppm, the temperature inside the car is about 20°C, and it feels comfortable;

1 minute, the carbon monoxide concentration in the car is 5ppm;

After 3 minutes, the carbon monoxide detector warning light began to flash continuously;

After 5 minutes, the carbon monoxide concentration in the car was 65ppm, and the detector warning light continued to flash and vibrate;

For 15 minutes, the carbon monoxide concentration in the car was 70ppm, and the detector warning light kept flashing and vibrating; for 25 minutes, the carbon monoxide concentration in the car was 91ppm, and the carbon monoxide detector warning light kept flashing and alarming. There is an obvious feeling of suffocation when entering the paint room, and discomfort can be clearly felt after 1 minute after entering the car.

From this experiment, it can be seen that in a closed garage, a car with air conditioning on will produce a large amount of carbon monoxide. In just over 20 minutes, the concentration of carbon monoxide seriously exceeded the standard, and there was an obvious feeling of suffocation.

Experts remind: In a sealed space, it is not safe to turn on internal and external circulation at idle speed

There are two situations in the air conditioning system, one is when the car is on external circulation, and the other is when internal circulation is on. "External circulation draws outside air into the cabin. In a relatively closed space like a garage, the amount of oxygen is not sufficient and the fluidity is not good. The exhaust gas emitted by the car can easily enter the cabin through the external circulation system. , thus leading to poisoning.

Experts also said: If you are driving, try to use external circulation. If you use internal circulation, you should often open the window for ventilation, otherwise it will easily lead to oxygen loss. < /p>

I have answered this type of question before. To improve your cognitive philosophy, simple common sense should know: Do not turn on the air conditioner in the car when the car is stopped and sleeping. People will be poisoned and die. This situation has been It happens frequently, so you need to pay attention. The car is fine when it is running. You must know this.

Try not to sleep in the car, especially close the windows and turn on the air conditioner. You can relax under the big tree in the rest area. Don’t drive when you’re tired, and get enough sleep.

In addition, don’t stay in the car all day long. Open the windows while driving to keep the air flowing. This is very important. As an adult, you should understand that the human body breathes in. A certain amount of exhaust gas can kill people. As a driver, if you don’t even know the basics, you are not qualified to drive a car but only a battery car!

I always think that this kind of thing will not happen to me, so I often underestimate it! Safety, negligence leads to tragedy.

When sleeping in the car, open the windows to avoid lack of oxygen.

It is not caused by the air conditioner.
