In summer, the frequency of using air conditioning while driving is high, and not using air conditioning in the car is not very comfortable, so there are also many problems with air conditioning. In addition to refrigeration issues, there are also many details about the use of air conditioning. What we are going to talk about today is whether it is possible to idle the air conditioning for a long time and what are the hazards? There are many situations where the air conditioning is turned on while idling

In summer, the frequency of using air conditioning while driving is high, and not using air conditioning in the car is not very comfortable, so there are also many problems with air conditioning. In addition to refrigeration issues, there are also many details about the use of air conditioning. What we are going to talk about today is whether it is possible to idle the air conditioning for a long time and what are the hazards? There are many situations where the air conditioning is turned on while idling, such as parking and waiting, resting in the car, or doing other things temporarily. If there are people in the car, the air conditioning must be turned on, otherwise the weather will be too hot for the people in the car to bear.

     As long as the car is not malfunctioning, idling the air conditioning for a long time will not have a significant impact except for increased fuel consumption, with only two aspects having a slight impact. If you can find a cool place, it is recommended to turn off the engine and wait for the air conditioning to idle for a long time. Firstly, it consumes a lot of fuel, and secondly, it increases emissions and pollutes the environment, which also has a slight impact on the car. First, let's talk about how long it takes to idle and turn on the air conditioning? There are no specific regulations, generally speaking, fifteen minutes or more is considered a long time. Some people stop for hours, even sleeping in the car with the air conditioning on, which is considered a long time. Stopping for only three to five minutes is not considered a long time, so there is no need to worry about idling and turning on the air conditioning.

    Why does idling the air conditioning for a long time have some impact? Firstly, it will cause significant pressure on the cooling system. Due to the high power of the air conditioning compressor, the increased load on the car is significant. For cars with smaller displacement, the power immediately decreases significantly after turning on the air conditioning, which can be clearly felt. When the engine load is high, it is necessary to increase the rich mixture to generate more power. As we can see, the idle speed will increase slightly after turning on the air conditioning. The heat generated by a rich mixture is relatively high. When the car is stationary, the heat can only be dissipated by the cooling fan blowing through the water tank. The cooling system needs to continuously work under load. If there is a slight problem with the cooling system, it can cause the water temperature to be too high and have a negative impact on the engine. Secondly, if the mixture is rich, there will be incomplete combustion of gasoline, and over time, carbon deposits will increase significantly. Even if the air conditioning is not turned on, prolonged idling will lead to an increase in carbon deposits, let alone an increase in engine load when the air conditioning is turned on. Incomplete combustion will exacerbate the generation and retention of carbon deposits.

       Finally, if the air conditioning is turned on at idle for a long time, the air inside the car will become dirty. If the ventilation in the vehicle is not good, it is easy to cause carbon monoxide poisoning in the car. Every summer, sleeping with the air conditioning on in the car can lead to poisoning. Even if there is no poisoning, if the air conditioning is left idle for a few hours, the air inside the car will become very bad, affecting physical health. Why is this? Car exhaust emissions contain carbon monoxide. If the car remains stationary, the concentration of carbon monoxide in the surrounding area will be relatively high. After turning on the air conditioning, the air outside the car will enter the car, and the concentration of carbon monoxide inside the car will also increase, which is harmful to human health.

  Although idling the air conditioning for a long time can pose the aforementioned hazards, the overall harm is not significant. If conditions permit, it is necessary to keep the air conditioning on for a long time in the car. The most important thing is to keep the air fresh inside the car. Park the car in a well ventilated area, open some windows, and do not affect your health. If the time is long and the frequency is high, pay attention to the impact of carbon deposits on the vehicle and clean the carbon deposits in a timely manner.
