Necessary knowledge of automobile using warm air in winter

1, don't turn on the warm air immediately when the cold car starts.

Many car owners like to start the warm air as soon as they get on the bus, but this is actually not appropriate. Because the engine has just started in winter and the temperature of the water tank is still very low, it is necessary to wait for about 3-5 minutes, and then turn on the warm air when the water temperature rises to normal temperature, that is, when the water temperature rises to the middle.

Because the oil needs to be lubricated from the oil pan to all parts in auto start, it takes some time. If the warm air is turned on at this time, it will not only increase the temperature in the car rapidly, but also increase the burden on the engine and delay the normal increase of the engine temperature.

Just like 100 meter athletes start from a person's back, it is bound to consume oil. The fuel cost is caused by insufficient internal lubrication and high friction resistance of the engine, but people will mistakenly think that it is caused by warm air.

2. Heating for a long time requires proper ventilation.

Setting the circulation mode of the air conditioner to the internal circulation mode is helpful to the rapid temperature rise in the car, but after using the internal circulation for a long time in the car, many people will have a feeling of poor breathing.

This is because the car itself is in a closed space and the air is not circulating. So when the temperature rises and the external environment is good, try to adjust to the external circulation.

3, the temperature should not be too high, do not blow directly on the face.

When driving in winter, the warm air temperature should not be too high, otherwise it will easily cause drowsiness and accidents. The wind direction is generally suitable for blowing legs and feet. When legs and feet are warm, the whole body will be warm.

In winter, the climate itself is relatively dry. Turning on the heating will make the air inside the car drier, make the skin dry and easily generate static electricity. Besides the car humidifier, you can also put a wet towel in the car.

4. Warm air can cope with repeated fogging in the car.

Cold air defogging is effective quickly, but many people will have repeated fogging in the car. You can try to turn on the warm air to demist.

However, it should be noted that the effect is not as fast as that of cold air, and generally lasts 1-2 minutes. The moisture on the glass is dried by hot air, and there will be no repeated fogging.

5. There are three reasons for the small amount of warm air.

1. The air conditioner filter is too dirty, resulting in only some air being sent in; If the filter element of the air conditioner is too dirty, it should be replaced.

2. The workload of the air-conditioning blower is too large, which may ablate the air-conditioning motor.

3. The blower regulating electric appliance is out of order, resulting in less air supply.
