Car warm air has an odor; What's wrong with the smell of car warm air?
There are several common reasons why cars smell when using warm air:
1, because the evaporator (also called evaporation box). The warm air of the car mainly comes from the heat of the water tank, which is inside the evaporator. Warm air is the process that the engine cooling system radiates heat to the engine, and the blower is used to blow heat into the cab.
If the time is long, there may be a small amount of moisture and dust attached to the evaporator, and the evaporator will be moldy, resulting in odor.
2. The air-conditioning duct has an odor. Due to humidity and mildew, the air conditioning pipeline has an odor. It is suggested that after turning on the air conditioner every time and 2 minutes before parking, turn off the air conditioner switch and turn on the external circulating air to continue blowing until parking. This practice can dry the moisture in the air duct and prevent mildew.
3. The air conditioner filter element has an odor. Air-conditioning filter has a service cycle and is usually replaced once every two years. Otherwise, it will be mildewed after a long time, which will lead to odor. And after a long time, bacteria will gradually accumulate in it, which is not good for human health.
What's wrong with the smell of car warm air?
The peculiar smell in the warm air is mainly caused by excessive air humidity or excessive condensed water generated by refrigeration in the air conditioning duct. Owners are advised not to turn off the engine after parking. You can let the car idle for a few minutes, let the air conditioning duct dry and then turn off the engine to avoid odor when you use it next time.
Attachment: Precautions for using warm air in winter:
1, the car can't turn on the warm air for a long time;
It is easy to feel poor suction when the warm air is turned on in the car for a long time. In winter, the windows are closed, and air circulation will inevitably appear in the closed environment. You can open a gap in the window glass during driving to exhaust the dirty air inside the car, or you can use external circulation to ensure that fresh air can enter the car.
2, warm air temperature should not be too high:
During driving, if the temperature of the warm air is set at a relatively high level, the owner will easily feel sleepy. Especially when driving at high speed, the driving time is too long, the temperature inside the car is too high, and the drowsiness is more serious. Pay attention to the outlet of warm air not to face people. Long-term hot air will make the air inside the car very dry and do great harm to the skin.
3, warm air can repeatedly break the window and fog;
In the process of driving, due to the large temperature difference between indoor and outdoor, it is easy to fog. Many car owners know to press the window defogging button, but the fogging phenomenon will appear repeatedly. Warm air can solve the problem of repeated fogging of windows.
