How to quickly keep warm when the car is cold in winter
How to quickly keep warm when the car is cold in winter. Even though our cars have become a very common means of transportation, people can do it without being exposed to wind and rain. It is very convenient, but many people will be very troubled by the hot summer. The following is about how to quickly keep warm when the car is cold in winter. How to quickly keep warm when the car is cold in winter 1
If you want to keep the car warm in winter, you can turn on the air conditioner. If there is a seat heating function, you can turn on the seat heating.
When driving in winter, you need to use air conditioning almost every day.
The air conditioner in a car can be used for both cooling and heating. Air conditioning is a very important comfort feature in a car.
The heating principle of the car air conditioner is very simple. When the car air conditioner is heating, the high-temperature coolant in the engine will flow through the heater water tank, and the wind blown by the blower will also pass through the heater water tank. In this way The air conditioner outlet can blow out warm air.
The heater water tank is actually a heat exchanger.
The refrigeration principle of the automobile air conditioner is also relatively simple. When the automobile air conditioner is cooling, the engine will drive the compressor to run, so that the compressor can compress the refrigerant and transport the refrigerant to the evaporation box.
The refrigerant will expand and absorb heat in the evaporator box, so that the refrigerant can cool the evaporator box. The cooled evaporator box can cool the wind blown by the blower, so that the air conditioner outlet can blow out cold air.
The refrigerant used in most car air conditioners is r134a. This refrigerant needs to be replaced regularly. If the refrigerant is not replaced for a long time, the cooling effect of the car air conditioner will become worse and the cooling speed will become worse. slow.
If you want to replace the refrigerant, you need to go to a professional store and have professionals use professional equipment to replace it.
Car owners cannot replace the refrigerant by themselves. How to keep warm quickly when the car is cold in winter 2
In winter, if you want to keep the car warm, you can turn on the heating mode of the air conditioner in the car to generate warm air. However, you need to be careful not to leave the engine idling for a long time with the heater on, as this can easily lead to carbon monoxide poisoning.
In addition, some higher-end vehicles have heated seats. This function can be turned on for heating when parking. It is also important to note that do not use the seat when the engine is turned off for a long time. The heating function will consume battery power faster, causing the vehicle to be unable to start, etc.
The above are some methods of parking and heating. However, car owners are reminded again that when using heating equipment or functions, they need to pay attention to avoid affecting the driving behind.
Car air conditioners are used for both cooling and heating, and their working principles are relatively simple. For example, when car air conditioners are heated, the high-temperature coolant in the engine will pass through the warm air tank, and The air blown by the blower will also pass through the warm air tank, so that the air outlet of the air conditioner can blow out warm air. The warm air water tank is equivalent to a heat exchanger, which transfers heat from hot fluid to cold fluid to achieve the heating effect.
People need to keep warm, and vehicles also need to be warmed. Especially in winter, you need to pay attention to the way you warm your car. The correct way to warm your car is to start the engine for 30 seconds to 1 minute before driving on the road, and During this process of warming up the car, keep driving at a relatively low speed, and then increase the speed evenly. How to quickly keep warm when the car is cold in winter 3
1. Keep the car body warm
If the car body is not cleaned frequently, residues will adhere to it and will be washed away by rain, especially those containing acid and alkali substances. The rainwater will oxidize the car body paint and cause discoloration. In autumn, as the rainfall increases, you should first keep the car body clean. If conditions permit, you can wax and seal the vehicle. The reticular protective film formed in this way can withstand cold, acid and alkali, and corrosion.
2. Keep the engine warm
In order to protect the engine in winter, the antifreeze must be selected correctly. The antifreeze must be replaced every two years, but the mixed antifreeze must be replaced every year. Then there is the lubricating oil. Winter has higher lubrication requirements for cars. If you use summer engine oil, it must be replaced. Engine oil that has been used for a long time and is black in color must be replaced in time.
3. Keep the battery warm
When the battery is relatively cold in winter, the discharge efficiency drops greatly. If the temperature in your location is very low in winter, pay attention to keeping the battery warm. If possible, apply special grease on the battery to ensure reliable start-up and extend battery life.

Other precautions for cars in winter:
1. Air conditioning inspection
p>Since the heater may malfunction if it is not used for a long time, you must first test whether there is hot air, whether there is any abnormal noise when the fan is running, and whether the air duct is smooth. Because the antifreeze in the heating air pipes does not flow for a long time, it will block the pipes. Although it does not affect driving, it is very troublesome to repair. If problems are found, they must be repaired in time.
2. Tire maintenance
When the weather is cold, the rubber will become hard and brittle. The tire pressure in winter should not be too high, but it should not be too low. Soft tires will age quickly if used at low pressure. In addition, inclusions in the tire tread should be cleaned frequently in winter, and tires that have been patched more than once should be avoided as much as possible. In addition, tires that have been used for a long time have different degrees of wear on the inside and outside. To ensure safety and reduce wear, the tires should be replaced regularly.

1. The correct way to turn on the heater
Many people have the habit of turning on the heater in their cars, which is wrong. When the engine is started in winter, the water tank temperature is low. Turning on the air conditioner in the car will not only not heat up quickly, but also increase the load on the engine. You must know that warm air uses the engine's circulating water to generate heat, and then blows out the hot air through the blower. The fuel consumption of turning on the heating is completely negligible. Turning on the heating in winter costs no fuel, but turning on the cooling in summer only costs fuel.
The correct method is: it is not advisable to turn on the heater immediately after starting the car. Wait for about 3-5 minutes. In other words, start the engine to warm up first, and then turn on the heater after the engine temperature pointer reaches the center position. For heating air conditioning, set the air circulation to external circulation at the same time, so that the cold air in the car can be swept away from the outside of the car. Wait for about 2 minutes, and then set the air circulation to internal circulation, so that the temperature inside the car can rise quickly!
Because the engine oil needs to be lubricated from the oil pan to various components when the car is just started, it takes a certain amount of time. If the heater is turned on at this time, the engine load will be increased and oil will be consumed. The oil consumed is the internal lubrication of the engine. It's caused by friction and resistance, don't think it's caused by turning on the heater.
2. Selection of car floor mats
For a car that is ready for winter, buying a pair of floor mats will make it warmer. In terms of selection, the store owner will recommend some so-called warm brand foot pads to you, such as wool foot pads, plush foot pads, etc. This type of mat does give people a very warm feeling both in terms of sense and use. However, combined with the winter weather, everyone will find that the applicability of this kind of foot pad is obviously insufficient.
Winter is cold, and the water molecules in the air cannot fully absorb dust, causing dust to spread in the air. Plush floor mats, on the other hand, have poor ability to absorb dust, and the floor mats themselves are prone to dust. These dusts can easily enter the body through the human respiratory tract and cause respiratory diseases. In addition, the safety factor of this type of mat is relatively low and it is easy to catch fire.
Purchasing tips: Silicone foot pads and rubber foot pads are good choices. These two types of mats have good cold resistance and low temperature resistance. They will not deform at more than ten degrees below zero. They are easy to clean and are safer than plush mats. In addition, thicker floor mats are not always better. Some consumers will put more emphasis on thickness when purchasing floor mats. In fact, the material of the floor mats is the most important. You must try it first after installing new floor mats. . Press the accelerator, brake and clutch pedals with your hands to see if they can go all the way.
3. Put on a warm seat cushion
Seat cushions are divided into pure wool and artificial wool, and the price ranges from a few hundred to several thousand. Wool cushions look luxurious and comfortable, like a fur coat. When the winter is cold, this kind of plush is most useful. The long velvet can give car owners a warm and spring-like feeling. However, the disadvantage is that it is not easy to clean.
Purchasing tips: Wool cushions are more expensive, so you need to be careful when purchasing. First of all, check whether the fur is dense, shiny and soft to the touch. Good fur does not smell bad.
The cushions with poor quality firstly feel bad to the touch, and more importantly, they smell a very pungent odor. Prices generally start at 1,000 yuan.
4. The suitable temperature of warm air
The most comfortable temperature for the human body is 20℃~25℃. When it exceeds 28℃, people will feel hot, and when it is below 14℃, people will feel "cold". Therefore, the temperature inside the car is best controlled between 18°C ??and 25°C. Generally, the temperature difference between the inside and outside of the carriage is within 10°C. The temperature is too high, and the temperature difference between the inside and outside of the car is too large, which can easily lead to colds when getting off the car. The temperature is too low, affecting driving comfort.
The above is an introduction to what to do if the car is too cold in winter. Now let’s take a look at what to do if the heater in the car is not hot in winter.
What to do if the heater in the car is not hot in winter
The reasons why the vehicle heater system is not hot can be divided into two aspects. One is caused by the engine cooling system, and the other is caused by the heater. It is caused by the poor working of the control mechanism. When repairing, we must first determine which cause is the cause, and then carry out corresponding repairs.
The method of judgment is very simple. Look at the temperature of the two water inlet pipes of the small warm air water tank. If both pipes are hot enough, it means there is a problem with the air volume control mechanism. On the contrary, if both water pipes are cold, Or if one is hot and the other is cold, it means there is a problem with the cooling system.
Possible problems in the cooling system:
1. The thermostat is always open or the thermostat is opened too early, causing the cooling system to start prematurely Large circulation, but the outside temperature is very low, especially when the car is running, the cold air will quickly cool the antifreeze, the engine water temperature will not rise, and the warm air will not heat up.
2. The impeller of the water pump is damaged or lost, causing insufficient flow through the small warm air water tank and preventing heat from coming up.
3. There is air blockage in the engine cooling system. The air blockage leads to poor circulation of the cooling system, causing high water temperature and low heating of the warm air. If there is always air in the cooling system, it is likely that the cylinder gasket is damaged and air is flowing into the cooling system; if the water inlet pipe of the small heater water tank is very hot and the water outlet pipe is cold, this situation should be that the small heater water tank is blocked. , the small heater water tank should be replaced.
Problems with the air volume control mechanism:
1. The warm air in the car uses a blower to blow the heat from the small warm air tank into the cab. If the air volume is not enough or the hot and cold air Poor distribution will prevent the heat from the small heater water tank from dissipating, and will also cause the temperature of the heater to not rise. At this time, first check whether the filter is dirty and blocked, clean it, and replace it in time if necessary.
2. Check the operation of each gear of the blower. Each gear must reach sufficient speed. If the knob is adjusted to the warm air position, the air volume is large enough, the wind direction is normal, and cool air blows out, you should check whether the cables of the hot and cold air control flaps of the heater box have fallen off, whether the warm air impeller is damaged, whether the flaps have fallen off, etc. After troubleshooting, the heater will heat up.
