The reason why the car is not hot and the solution

Heater tank blocked

The structure of the heater tank is actually a reduced version of the engine tank radiator. There are a number of small heat-dissipating pipes inside, which are easily blocked inside the tank radiator. The coolant flowing through the inside of the heater tank becomes slower, the flow becomes smaller, the heat is insufficient, and the air conditioner is not hot.

Cooling system lacking coolant

The coolant is commonly known as antifreeze, and the air conditioner heater comes from this. The principle is different from that of household air conditioners. The car warm air cycle is a parallel pipeline in the engine coolant small circulation pipeline. The heater is connected to the heater tank. The blower blows the heater tank to generate warm air. The air conditioner heater is like this. The lack of coolant in the cooling system is the most common and easiest solution to the problem of warm air.

The reason why the car is not hot and the solution

Thermostat failure

The common fault of the thermostat is that it cannot be opened, but the cause of the warm air is not hot due to the failure of the thermostat. However, the thermostat cannot be turned off, which is commonly called the thermostat. After the thermostat is normally open, the coolant starts from the engine idle speed. If the water temperature in the north is low for a long time, the air conditioner heater is not hot naturally. It can be clearly seen from the water temperature gauge that the needle is significantly lower than the normal scale. In addition, the engine water temperature is low for a long time, which will lead to excessive fuel consumption and increased wear (the engine is not working at the optimum temperature). If the water temperature is low for a long time, it needs to be repaired immediately.

How to warm the wind

1. After the car is started, after about 8-15 minutes, the water temperature rises to the normal temperature, and the warm air can be turned on. (that is, when the water temperature rises to the middle)

2. Adjust the circulation mode of the air conditioner to the inside of the car.

3. Adjust to the warm air mode, some cars are red, some cars are represented by the sun

4. Do not turn on the air conditioner (do not turn on the AC switch), because the warm air is using the car's own thermal cycle to save energy!

5. Appropriate gear position for air conditioning gear adjustment, adjust the wind direction of the air outlet. The direction of the warm air is generally blowing forward and under the foot, and the cold air is generally for the forward blowing.

The above describes the reasons for the car's warm air and the related content of the solution. Let's take a look at the main points of using the warm air in winter.

The temperature should not be too high. Do not blow the face straight.

The warm air temperature should not be too high when driving in winter, otherwise it will easily cause drowsiness and cause an accident. Especially in the process of driving on a highway, if the temperature of the warm air is too high, it is easier to increase the drowsiness of the owner, and there is a high possibility of an accident.

In order to prevent the car from being too dry, a wet towel can be placed inside the car and laid on the dashboard. After turning on the heating, the air outlet should not be directly directed at the face. The hot air that is dried for a long time will accelerate the skin aging, and women should be extra careful. Furthermore, the hot air rises and the heating from the lower part can achieve better and faster heating. When the hot air is just opened, the rear window is slightly open for a period of time. Due to the entry of hot air and the overflow of the cold air, the heating effect is reflected more quickly.

Do not start the warm air immediately after the cold car starts.

Many car owners like to start the air conditioner to warm the wind when they get on the bus, but this is not the case. Because the engine has just started in the winter, the temperature of the water tank is still very low. Turning on the air conditioner will not only increase the temperature inside the vehicle quickly, but will increase the burden on the engine and delay the normal increase of the engine temperature. The engine warm-up should be started first, and then the engine temperature indicator is turned to the middle position, then the warm air is turned on, and the air circulation is set to the outer circulation, so that the cold air inside the vehicle is discharged outside the vehicle, and then wait for 2-3 minutes, then the air is taken. The loop is set to the inner loop.

In addition to turning on the air-conditioning heater, you can also use the engine radiator water temperature to provide heating, so that you do not need to open the compressor, the fuel consumption of the air conditioner is much smaller.

Warm winds are prone to bacteria, keep dry and smoke less

In the winter, the windows are closed for a long time, so that a large number of bacteria have the opportunity to reproduce in the car. Therefore, we should pay special attention to the prevention of bacterial growth when using warm air. Preventing the generation of wet fog is very simple. You can turn off the heating in a few minutes before parking, and open the natural wind for a while in the open state, so that the temperature inside the air conditioning pipe will be close to the outside temperature, thus ensuring the relative dryness in the air conditioning system. .

Smoking when the air conditioner is turned on in the car will cause a large amount of amine and nicotine in the soot to adhere to the surface of the evaporator. When the weather is long or rainy or the air conditioner is not used for a long time, the surface of the evaporator will produce mold and seriously pollute the air inside the car. Therefore, it is best not to smoke when turning on the air conditioner.

Turn on the heater for a long time and properly ventilate

After the air conditioner is warmed up for a long time in the car, many people often feel a feeling of being uncomfortable when they feel the warmth. This is because the car itself is in a confined space, and heat is constantly exchanged during breathing, and the air is not vented. In this regard, the owner can open a small slit in the four windows to drive out some of the dirty air inside the car, which will effectively relieve the symptoms of chest tightness after turning on the air conditioner.

Warm air can cope with repeated fogging in the car

Many car owners know that pressing the window defogging button will automatically blow the cold wind to the windshield, which can quickly eliminate the fog on the window. In the face of repeated fogging, the owner can try to open the way of warm air de-fogging, turn the air conditioning temperature adjustment button to the warm air direction, and the air conditioning direction button is turned to the glass air outlet, when the hot air will directly blow the front windshield. However, it should be noted that this method of warming the wind and defogging will not start as fast as the cold air, and will generally last for 1-2 minutes. The hot air will be dried by the hot air, and will not appear repeatedly. The situation of the fog.

The above is about the reasons for the car's warm air and the solution, and I hope to help everyone.
