Reasonable use of car air conditioning in winter

Winter is coming soon. When we go out in the morning, the car will have a lot of fog, stay in the car during the day, and the car glass is also mist, how to do the fog! Xiao Bian will give you a talk today.

First, the use of automotive air conditioning in winter requires special maintenance: Be careful about your air conditioning strike.

Do not think that only the summer will be used to car air-conditioning, in fact, the same winter, the use of car air-conditioning frequency is as high. In the cold winter, many people have the habit of heating when they enter the car; when it rains, the window glass fogs. The easiest way is to eliminate air conditioning. How to use the air conditioner correctly, there are many other things.

1. Take a long rest or sleep in an air-conditioned parking van.

Because the car is sealed well, when the vehicle is parked, the ventilation in the cabin is poor. If the air conditioner is used for rest or sleep at this time, the CO gas emitted from the engine may leak into the vehicle and cause poisoning and even death.

2, pay attention to the operating sound of air conditioning. If you hear unusual noise during air-conditioning operation, such as metal impact noise, motor noise, shell vibration sound, etc., should immediately shut down to check the cause.

3, often cleaning the air filter, usually two or three weeks to clean;

Frequent cleaning and regular replacement of air conditioning filters can maintain good air conditioning quality.

Under normal circumstances, every 5,000 km or 3 months (whichever comes first), the air-conditioning filter should be cleaned once every 20,000 km or 12 months (whichever comes first) to replace the air-conditioning filter.

4, protect the condenser and evaporator heat sink.

The fins of the condenser and the evaporator are formed by inserting a 0.15 mm aluminum sheet into the copper tube and then expanding the tube, failing to collide, if the heat sink is damaged. It will affect the cooling effect of air conditioning;

Clean the condenser often. After driving in rain or muddy sections, check whether the condenser fans have sediment and stones. If any, clean them in time. The owner of the car-repair car beauty shop said that some owners often use hoses to rinse the condenser when using air conditioners in summer. This is quite true. Because the surface of the automobile condenser is easy to clean, heat energy can be dissipated to the outside. Regularly cleaning the condenser surface can greatly improve the cooling effect of the air conditioning system.

5, protect the refrigeration system.

If the components of the refrigeration system or the connecting lines are damaged, the refrigerant leaks and the air conditioner cannot be cooled;

The correct choice of fuses. Select the fuse size according to the rated current indicated in the product manual. If the size is too large, no insurance effect will be obtained. If it is too small, it will often melt.

6, to prevent electrical system moisture. After the electric system is exposed to moisture, it is easy to leak electricity. Therefore, the electric system parts should not be flooded, especially during the rainy season, and more attention should be paid to moisture prevention.

Second, improper use of air conditioning in winter is very dangerous, teach you clever use of air conditioning!

1, quickly improve the car temperature.

When the car just started, do not immediately open the air conditioning fan, because the car has just started, the engine water temperature has not yet come up, this time open the air conditioning will blow out the original little heat, you know that no kind of engine will have the most suitable The problem of work, the temperature is too low or too high not only bad for the engine but also increase fuel consumption. The correct approach is to start the engine warm-up first, wait for the engine temperature pointer to the middle position, first turn on the warm air air conditioner, and set the air circulation as the outer circulation, let the cold air inside the car out of the car, wait 2-3 minutes After that, set the air circulation to internal circulation.

2, with the car air-conditioning fog.

Many owners know that pressing the window defogging button will automatically blow cold wind to the windshield, which can quickly eliminate the fog on the windows. But sometimes, the owner will find that the fog has just started growing soon. In the face of this fickle fog, how should the owner respond? At this time the owner can take the way to open the warm air and remove the fog, turn the air conditioning temperature control button to the warm air direction, and turn the air conditioning direction button to the glass air outlet. At this time, the hot air will blow directly to the front windshield. The method will not be as fast as the previous method. It will generally last for about 1-2 minutes, but it will not re-erate because the hot air will dry the glass's moisture.

3, how to prevent drying.

Driving inside the car can not be the first person at the outlet to blow, so easy to dry the skin;

Second, it is recommended that half-open windows allow air to flow;

A vehicle-mounted humidifier can be used in the vehicle, and a wet towel can be placed on the dashboard in the vehicle.

In addition, you should drink plenty of water and use less cosmetics. In addition, it is also recommended that users use the heating function in the winter to break the air-conditioner into the outer circulation at intervals and let fresh air from outside the car come in, which is good for the human body.

4. How many degrees of air conditioning in the car should be set in winter?

The most comfortable temperature for people is 20°C to 25°C. Above 28°C, people feel hot, and below 14°C, people feel cold. Therefore, the temperature in the vehicle is preferably controlled between 18°C ​​and 25°C. General inside and outside the temperature difference is within 10 °C is appropriate.

Today, energy conservation is being implemented throughout the country. The indoor temperature in winter is not less than 18 degrees, and how much should be in the car. It's too hot and too cold. It's not good for our health. It's overheated. It's cold outside and it's cold. It's cold. It's too cold. It's uncomfortable and affects the safety of driving.

Conclusion: The correct maintenance of automotive air conditioning can not only improve the service life of air conditioners, but also maintain the good working condition of air conditioning systems. Therefore, the maintenance and maintenance of air conditioners has become an important issue.
