Do you need to wait for the water temperature when the car is turned on for air conditioning and hea

In winter, when the car is turned on for air conditioning and heating, it is necessary to wait for the water temperature to rise to the normal temperature before use. In winter, the temperature of the water tank is low, and the engine is just started to turn on the warm air, which is bound to increase the burden on the engine, delay the rise of the water temperature, and even if the warm air blows out, it is also a cold wind, and the body feels uncomfortable.

The correct way is to use the heater when the water temperature pointer reaches the middle position or the blue indicator light goes out, and it is recommended to open the external circulation first, exhaust the cold air in the car, and then turn to the internal circulation after a few minutes, so that the warm air that blows in is the warm air.

In winter, the air conditioner cannot be turned on directly after the vehicle is started in the morning, and the heater and air conditioner need to be turned on after the water temperature rises.

Because when the car starts, the engine starts to warm up, and then when the engine temperature pointer points to the middle position (the sign of water temperature rising), the heater and air conditioner are turned on first, and the air circulation is set to external circulation.

Main advantages: Preheat the engine first, warm up the car while walking, and then turn on the heater after the engine temperature rises about the same. At the same time, it is necessary to pay attention to adjusting the air circulation to the outside.

Circulation, in order to quickly exhaust the cold air in the car, after two minutes to adjust to the internal circulation.

Can. This is a very practical little method, not only does it heat up quickly, but it also does no harm to the engine.

Heating is the use of heat from circulating water, and has nothing to do with air conditioning. Generally, the water temperature can be turned on when the temperature rises to 60 degrees. Gasoline cars can be turned on for 10 to 15 minutes. The water temperature on the diesel car is slow, and it will be fine after about half an hour.

1. It is not air conditioning heating, but warm air heating.

2. The heating temperature comes from the temperature of the water in the warm air tank, and the temperature of the water in the warm air tank comes from the temperature of the engine operation. Therefore, when the engine temperature rises, turn on the heater switch, and the fan blows out the heater. If you turn on the heater switch just after starting, the wind blowing out is cold.

Yes, when heating the car air conditioner, introduce hot water from the radiator.

Reason: The large amount of heat emitted by the air conditioner for a long time will consume most of the efficiency of the cooling system, and the slower cooling system will cause the water temperature to rise.

The water temperature of the car water tank is generally required to not exceed 95 degrees Celsius, and when the water temperature reaches the boiling point of 100 degrees Celsius, it is the so-called "boiling pot".

There are many reasons for "boiling the pot", such as hot weather, overloaded air conditioning, or failure of heat dissipation components. Especially in summer, the high temperature is unbearable, and the congested traffic in the urban area leads to frequent stops and starts, which exacerbates the friction of engine parts and causes the temperature to rise.

As soon as the car turns on the air conditioner, the water temperature will be high, which should be a problem of poor heat dissipation.

Troubleshooting and handling methods:

1. Check whether the electronic fan is working normally and whether the air deflector is damaged. If there is a problem, the ventilation and heat dissipation effect will not be effective when parking.

2. Whether the outside of the radiator and condenser is dirty, if it is cleaned, it is OK.

3. Check whether the water temperature sensor is normal.

Precautions for turning on the air conditioner in the car.

When you hit the road with the air conditioner on, think about turning off the air conditioner a few minutes before parking and turn on the natural breeze later. Because the temperature in the air conditioning duct rises before stopping, the temperature difference with the outside world will be eliminated, which can keep the air conditioning system relatively dry and avoid the reproduction of mold.

Some people don't pay much attention to it, after turning on the air conditioner, let the wind direction of the air conditioner blow at will, or even choose the mode of blowing the windshield, which is not right, because the high temperature of the windshield will cancel out most of the cooling effect. Therefore, it is best to choose to blow upward, in line with the law of cold air sinking, and it is best to choose a blowing surface block for the wind direction gear, and the best effect is to adjust the air outlet upward.

It is normal for the water temperature to be higher when the air conditioner is turned on than normal when the air conditioner is not turned on. The air conditioning system has its own heat dissipation device that cools itself down through cooling water! There may be several reasons for the increase in water temperature: 1. The cooling fan does not turn.

The cooling fan may be controlled by a thermostat switch; It may also be controlled by a water temperature sensor. 2. Insufficient cooling medium. Antifreeze:

High-end cars are required to be filled with antifreeze all year round; Water or distilled water: temporary substitute; The water tank cover is leaking. 3. The thermostat is damaged.

If you want to remove the thermostat, you should plug the small circulation at this time, so as to ensure that all the coolant is dissipated by the water tank; When installing a new thermostat, you should pay attention to the water hole, such as Santana does not have a water hole, at this time, a 6mm drill bit should be used to drill a hole. One function is to be used as a marker; Another function is that during the heating process of the car, the temperature difference between the two sides of the thermostat is generated, so that the thermostat is accurately opened with the water temperature. Fourth, the water tank is clogged.

External blockages should be removed with water or gas; Internal blockages affect coolant circulation and create pressure, which can result in two outcomes, one is a leaking water tank or the other is a particularly high water temperature at high speeds. 5. Pump failure. The impeller slips or gets stuck, causing the timing belt to break; The impeller is deformed.

6. Cylinder corrosion. The combustion chamber and the waterway are flushed, and at this time, the water will be drained from the drain pipe or white smoke will be discharged, resulting in a frequent shortage of water in the water tank; The waterway and the oil channel are flushed (the oil is white when there is water); The waterway and the waterway are rushed, resulting in poor heat dissipation of the cylinder block, especially at high speed; Blocked waterways. 7. The ignition timing is incorrect.

In winter, the car air conditioner needs to wait for the water temperature to come up. The car air conditioner itself has no heating function, and the warm air is better than the heat dissipation of the engine. This is also one of the reasons why the air conditioner needs to rise before the water temperature of the car rises.

Things to pay attention to when opening the air in winter:

1. Do not turn on the heating air conditioner immediately when the car is warmed up in the morning, and wait until the water temperature of the engine water tank rises before turning on the nuclear air conditioner.

2. The temperature of the air conditioner should not be too high, generally not higher than 23 degrees, the temperature of long-term overheating will make you sleepy and affect driving, and do not let the warm air blow directly on your face.

3. If the window starts to fog up after opening the warm air, most people turn off the warm air or use the cold air to drive the fog, which will cause repeated fogging, so increase the wind speed of the warm air and blow it for a while, so that the fog will disappear and will not appear repeatedly.

4. When driving for a long time, you should change the air every once in a while, and the air circulation in the confined space is not smooth, which will also cause the people in the car to breathe poorly for a long time.

The heat generated by the empty engine operation brings the thermal grinding hidden energy to the cab, which is then circulated through the antifreeze. There is a small water tank on the dashboard of the cab. At this time, turn on the fan to blow the air, and a steady stream of heat will come.

That is, the modulation of the car's empty heat dispersion depends on the temperature of the water.

The automobile air conditioning device is mainly composed of refrigeration system, heating system, air supply system and control system. In order to meet the needs of various types and purposes of automobiles, the composition of the automotive air conditioning device will be different.

According to the type of heat source, there are two main types of automotive heater systems: one is engine coolant (currently used in most vehicles) and the other is fuel (used in a few mid-to-high-end vehicles).

This kind of heating system is favored by the majority of automobile manufacturers because of its low cost and high heating efficiency. When the engine coolant temperature is high, the coolant flows through the heat exchanger (commonly known as the warm air small water tank) in the heating system, and the air sent by the blower is heat exchanged with the engine coolant, and the empty air is heated by the blower and sent into the car through various air outlets.
