How to adjust the car air conditioner in winter?

In winter, the weather is getting colder and colder, and many car owners turn on the air conditioner in their cars. How to use the air conditioner in winter? Let's take a look at the correct use of car air conditioners in winter.

Correct use of automobile air conditioning in winter

How to quickly raise the temperature inside the car?

Don't turn on the air conditioning fan immediately when the car just starts, because the engine water temperature hasn't come up yet. At this time, turning on the air conditioner will blow out a little heat inside. You know, no engine will have the most suitable problem for work. Too low or too high temperature is not only bad for the engine, but also increases fuel consumption.

The correct way is to start the engine warm-up first. After the engine temperature indicator reaches the middle position, first turn on the warm air conditioner, and set the air circulation to external circulation, so that the cold air in the car can be discharged outside the car. After waiting for 2-3 minutes, set the air circulation to internal circulation.

How to use car air conditioning in winter

How to use automobile air conditioner to remove fog skillfully.

Generation of fog

We won't elaborate on the principle of window fogging. Simply put, it is caused by the temperature difference of "external cooling and internal heating". When the temperature inside the car is higher than the outdoor temperature, fog is formed. In this paper, the water mist we refer to refers to the inside of the glass, so the role of the wiper is not great.

Demisting method

1 window convection

If there is not much fog in the car, we can open a gap in the windows on both sides, so that the air inside and outside the car can form convection, the temperature difference is reduced, and the fog slowly disappears. The principle of this method is the same as turning on the air conditioner, but it does not increase fuel consumption. The disadvantages of window convection are very obvious, which are not available in rain and snow, highways and foggy weather. Opening windows will reduce the temperature inside the car.

2 air conditioning system

For most car owners, using air conditioning system to remove fog is the most common. At present, almost all cars on the market have air conditioning outlets under the front windshield. Just select the air conditioner to the corresponding gear and use the air blown by the air conditioner to demist. But cold air or warm air? Cold/warm air has its advantages and disadvantages. If you are in a hurry, you can use cold air for emergency. In most cases, we still recommend that you use warm air.

Turn on the fan and refrigeration switch in the car, and the fog will soon disappear when the cold wind blows on the front windshield, and the effect is very direct. But this method has one of the biggest disadvantages, that is, people in the car will feel very cold. In the already cold winter, it is uncomfortable to blow air conditioning from the air conditioner. At first, the fog in the car will get bigger, because the temperature difference between inside and outside is bigger, and the fog will disappear after the hot air dries the water in the car. Special note: If you use this method, please use warm air to demist the fog before driving, and wait until the fog disappears completely on the road.

How to prevent drying when heating in the car?

In winter, the climate itself becomes dry. When the heating is turned on, the air inside the car will be drier. For women who love beauty, dry skin has become a big problem. Dry air is easy to generate static electricity in the car, which makes people feel uncomfortable.

In this regard, professionals suggest that heating in driving should not aim the air outlet at people first, which will easily dry the skin; Secondly, it is suggested to open the window half to let the air circulate; You can use a car humidifier in the car, or you can put a wet towel in the car and spread it on the dashboard with an indigenous method. In addition, drink more water and use less cosmetics.

In addition, it is suggested that when users use the heating function in winter, they can turn the air conditioner into external circulation every once in a while, so that fresh air outside the car can come in, which is good for people's health.

How to improve the air quality inside the car

These methods cost nothing.

1, internal and external circulation of air conditioner is used alternately.

When driving in winter, most people like to close the windows, so the air quality inside the car will get worse and worse because of poor air circulation. How to catch all the temperature and fresh air when the outside temperature is low? The most effective method is to use the "internal/external circulation" of air conditioner alternately, and the specific operation can be determined according to the road conditions: when the road environment is open and there is no odor or sandstorm, the "external circulation" mode must be used when the window is not opened; The road sections with serious traffic jams and exhaust emissions can be changed to "internal circulation" mode in time.

2. Lower the window a few centimeters or open the skylight.

The method of alternating internal and external circulation is to ensure the temperature inside the car without losing fresh air, but in fact, this circulation process is relatively long, which is not practical in extreme situations such as serious traffic jams. In fact, the more direct way is to open the window occasionally to ventilate and lower the windows on both sides by a few centimeters. For vehicles with skylights, the skylights can be opened with a gap-the time should not be too long, and they can be closed after 1 minute, and good air circulation can be obtained in a short time after convection. Of course, the frequency of opening windows must be based on your own adaptation, otherwise you will lose more than you gain if you catch a cold.

During long-distance driving, experienced masters generally suggest: open the window for convection every 1 hour.

These methods all cost money.

1. Thoroughly clean air conditioning pipes and air filters.

The car has been used for a long time, and the air conditioning filter of the car must be covered with dust accumulated for a long time. Too much dust will blow harmful mold into the car through air conditioning, which will bring hidden dangers to the body. Second, it will hinder air intake and greatly reduce the heating efficiency of hot air. Therefore, after entering the winter, it is recommended to drive your car to 4S shops and repair shops to thoroughly clean the air conditioning pipes and air filters, or simply buy a set of cleaning equipment online to thoroughly clean the air conditioning filters.

Especially if there is too much dust or mildew on the air conditioning filter element, it must be replaced immediately. If you think that the quotation of 4S shop is too high, you can buy an air-conditioning filter suitable for this brand online, and the price is about tens of yuan to 100 yuan.

If you can still smell the odor, such as mildew or odor, when you turn on the air conditioner after cleaning and replacing the new air filter, it is probably something wrong with the air duct of the air conditioner, especially the car that has been used for several years. In this case, it is strongly recommended to go to the 4S shop to clean the air outlet pipe. Of course, you can also DIY: inject the cleaning agent into the air outlet of the air conditioner and adjust it to internal circulation. The maximum wind speed is about 15 minutes, so that the cleaning agent can be fully circulated in the air duct to achieve the purpose of purification.

2. When vacuuming and cleaning the car, don't ignore the mat and seat.

When asked whether to wash the floor mats when washing the car, many people will give up because they don't like water stains or wet cold, or ignore the process of cleaning the floor inside the car. In fact, the floor in the car is the part where all kinds of soles will be stepped on. Most of the dust in the car collects directly on the mat or floor. Once the dust is raised, it will directly harm the exhalation system of the body, especially when the windows are closed and the hot air is turned on in winter. Once these eluvial soils are inhaled, I believe that your nose and throat will be affected for a long time.

In addition, the fabric seat surface often absorbs a lot of dust, which is also a point that drivers easily ignore. Therefore, it is suggested that the floor and seats in the car should be vacuumed regularly in winter to minimize the dust in the car. Generally, there is a vacuuming service when washing the car. You can also bring a small vacuum cleaner with 12V power supply for your car in case of emergency.

3. Ozone sterilization is recommended for smokers who often smoke in the car to use it regularly.

It is suggested that drivers who carry more people or smoke in their cars regularly disinfect their cars. At present, most automobile beauty shops have disinfection business, such as ozone disinfection and steam disinfection. Comparatively speaking, more car owners choose ozone disinfection, because the price is lower than steam, the disinfection time is shorter than steam, and the cost is about one or two hundred yuan.

4. The negative oxygen ion generator is simple and practical.

This is a very popular air purification device, which is sold in online shopping malls and major auto parts cities. Prices range from tens of yuan to several thousand yuan. The use method is simple. Just connect the 12V power supply and put it in the car. No other operation is needed, and negative oxygen ions will be released after electrification.

According to reports, the working principle of this negative oxygen ion generator is that the free electrons generated by the ionization of air molecules under the action of high pressure or strong rays are generated by oxygen, and the main functions of negative oxygen ions on the human body are to improve lung function, improve myocardial function and promote metabolism. This thing is more useful for friends who smoke, because negative ions can quickly neutralize the combination of coke smoke, oil fume and floating dust belonging to positive ions in the air, and achieve the effect of smoke elimination and dust removal.

In particular, it should be reminded that this generator has certain functions, but don't believe the exaggerated elements in some propaganda words during use.
