1. Abstract: The heat source of the air heater is to use the residual heat of the engine cooling water and send it to the radiator of the fan heater through the water pipe.As long as the engine does not turn off, the cooling water maintains a "small cycle" with the radiator. It is connected in parallel with the engine radiator. Because the radiator of the heater does not have a thermoster, the heat source can be maintained continuously.

2. Warm air is the heat generated when the engine is working: when the cooling system of the engine dissipates heat to the engine, the heat emitted is sent into the car through the fan to form warm air; when the warm air is not used, the fan stops turning, the hot air outlet is closed, and the heat emitted will be completely dissipated into the atmosphere.

3. The heating in the car air conditioner comes from the engine. The temperature is too low in winter, so it is a problem for the car to start outside. Therefore, the car can only run normally after the water temperature rises. The best time to turn on the warm air is when the temperature of the refrigerator reaches more than 90 degrees, and the best time to turn on the warm air when the car is hot.

4. It is indeed a more economical plan to use the residual heat of the engine for the warm air of the additional program car. The power source of the additional program car is mainly the battery, but the engine will also generate a lot of residual heat while charging the battery.

Car, how does the hot air of air conditioner come

The hot air opening method of the car air conditioner is to first adjust the cycle mode of the car to the internal circulation, and then turn on the air conditioning switch to the hot air mode. The switch signs of the air conditioner of different models are different. According to the switch of the car model, turn on the air conditioning mode first, and the cycle mode in the car should also be set to the inner circulation, because the warm air of the car is used The car itself.

The source of car warm air is the coolant water temperature. When using it, you only need to pay attention to adjust the internal and external circulation and pay attention to ventilation. The car air conditioner itself does not have the function of heating. The compressor compresses the refrigerant, commonly known as the snow species. There is no need to use the compressor for heating at all.

The working principle of the automobile air conditioning system is actually the principle of releasing heat during liquefaction and absorbing heat during vaporization learned in junior high school physics. The details are as follows: Heating principle: the drive belt of the engine drives the compressor.

The plumbing heating device generally uses the coolant in the water-cooled engine cooling system as the heat source, introduces the coolant into the heat exchange in the car, so that the blower sends the air in the car or the outside air to exchange heat with the coolant in the heat exchanger, and sends the heated air into the car with the blower. .

In the cold season, we need to raise the temperature in the car quickly. When the car starts, the engine begins to warm up. When the temperature pointer of the engine points to 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 out of the car.

Does the car need to be started to turn on the warm air

1. When the warm air is turned on, the engine needs to be started. Only when the engine reaches the normal operating temperature will the on-board air conditioner blow out the warm air.Car air conditioning is a very important comfort configuration for cars. Car air conditioners can be used for refrigeration or heating. When driving in winter and hot weather, you have to use the car air conditioner almost every day. When the car air conditioner is cooling, the compressor clutch will be combined.

2. When the vehicle starts, the engine will generate a lot of heat, which requires a cooling system to assist in heat dissipation. Therefore, the plumbing air conditioner will not consume fuel during heat exchange. If the heating is not turned on, the heat will be discharged out of the car.

3. It's easy to burn the line if you don't start it without starting it. And don't turn on the warm air immediately after getting on the car, because most of the cases when you need to turn on the warm air are when it's cold around. At this time, the temperature of the water tank in the car is low, and the air sent is also cold air, and this is not very friendly to the engine. Well, doing this often also affects its service life.

4. The engine should be started when the air conditioner in the car is turned on. The car warm air system is a complete set of devices that blows cold air to the surface of the heat exchanger, absorbs its heat and guides people into the car, thus raising the temperature in the car.

How to get hot air faster in winter

1. Start the engine preheating first, wait for the engine temperature pointer to point to the middle position, turn on the warm air and air conditioning, and set the air circulation to external circulation at the same time, so that the cold air in the car Expel the car from the car, wait for about 2 minutes, and then set up the internal air circulation. The AC button is the switch of the air conditioner compressor.

2. The way to turn on the warm air in the car in winter is 1 start the engine to warm up 2 turn on the warm air when the engine temperature is above 40 degrees Celsius 3Turn on the external circulation and discharge the cold air in the car to the outside of the car. 4 Turn on the internal circulation. Precautions for turning on the warm air of the car. 1 Do not turn on the warm air immediately after the car starts. 2 The window of the car is foggy.

3. The method of heating the car air conditioner in winter is 1 wait for about 3 to 5 minutes after the car starts, and turn on the warm air when the water temperature rises to normal temperature. 2 set the circulation mode to the internal circulation mode, which is conducive to the rapid heating of the car, and then switching the external circulation on demand to help the air circulation in the car when turning on the warm air You need to press the AC key, because.

4. Usually, the switch of the warm air system is on the central console of the vehicle, which can be operated through the button or knob. Set the warm air system to internal circulation mode, so that the cold air in the car can be quickly heated and the temperature can be increased. When the temperature in the car is suitable, it can be changed to the external circulation mode to prevent the window from fogging.

5. The warm air heats up quickly. First of all, start the engine, adjust the engine temperature and other pointers to the middle position, turn on the warm air conditioner, set up the air circulation outside for circulation, maintain the air circulation in the car, wait for 2 minutes, and then set the air circulation to the internal circulation, so that the temperature in the car It can rise rapidly.

6. Therefore, if you want to get warm air quickly, the best way is not to heat the car in place; and the in-place heating car is just an operation that has to be carried out in the carburetor era because low-temperature fuel cannot be ideally atomized. The electric injection cars produced in the past 20 years do not need to heat in place, and lubrication is only formed in a few seconds, less Listen to the so-called veteran driver's trick.
