Do I need to turn off the air conditioner when driving on a deep water road?

Hello, driving on a deep water road has nothing to do with air conditioning, you don't need to turn off the air conditioning, specifically, I hope it can help you!

First of all, it is not recommended that you drive a deep water road, since you must drive, then resistance is inevitable, and there is also the possibility of overhauling the engine.

As for whether to turn on the air conditioner, this is not in conflict with taking a deep water road, as long as the car is not flooded and turned off, the water will not enter the air conditioner. The air vents of the air conditioner are about the same height as the air intakes of the engine.

Just driving in a low gear on a deep water road, and adding the fuel consumption of the air conditioner, the total energy consumption will be very high.

Yes, you need to turn off the air conditioner when driving on a deep water road, but generally do not drive on a deep water road, which will cause damage to the car.

If you drive on a deep water, it is best to turn off the air conditioner to prevent the air conditioner from getting water, which will easily damage the car air conditioner.

If you drive in deep water, as long as the vehicle can pass the tires, you must turn off the air conditioning.

Do I need to turn off the air conditioner when driving on a deep water road? It depends on your personal habits, most people will turn off the air conditioner to avoid water.

You don't need to turn off the air conditioner, and you don't need to turn off the air conditioner when driving on the mountain road, but you do. It's slow.

Yes, otherwise the air intake of the air conditioner is easy to get water, which is not good for the car.

Do I need to turn off the air conditioner when the car is on a deep water road? It's best to turn them all off, as it's not safe to get an electric sleeper.

It mainly depends on what the depth of the water you are talking about, if it is very shallow, it is not used, if it is very deep, it is recommended to pass at a flat speed.

Do I need to turn off the air conditioner when driving on a deep water road? If you drive in deep water, you need to turn off the air conditioner.

The correct way to use the car air conditioner:

1. Generally, the button on the left side of the car represents the cold wind, while the red represents the heating, and the middle represents the moderate cold and warm.

2. If you want to turn on the cold air, the left button of this picture is adjusted to the blue place, and when you want warm air, adjust it to the red place, and then press the AC switch, and the key in the middle is the size of the open air, and the one on the far right is the adjustment mode, you can adjust it to only blow your feet or hands or glass, or you can use the two more modes at the same time.

3. The white line on the left is to adjust the temperature, you can adjust it to the middle when you feel too warm, and you just need to turn off the fan in the middle without turning on the air conditioner.

Summer is coming, how to use the air conditioner correctly?

The main components of automotive electrical appliances 1 power supply system include batteries, generators, and regulators. Among them, the generator is the main power supply, and when the generator is working normally, the generator supplies power to the electrical equipment of the whole vehicle, and charges the battery at the same time. The role of the regulator is to keep the output voltage of the generator constant.

In the summer, after the vehicle is slammed, harmful gases will be produced in the car, and if the air conditioner is not opened without opening the window, it will not only cool down slowly but also inhale harmful gases. Let's find out the correct way to turn on the air conditioner.

Automobile air conditioner is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in the best state, provide a comfortable riding environment for the occupants, and reduce the fatigue of the journey; Ventilation devices that create good working conditions for drivers and play an important role in ensuring safe driving. It generally includes refrigeration units, heating units and ventilation units.

Start the vehicle, open the windshield, turn on the AC switch, and adjust the position of the air outlet.

How to use the car air conditioner correctly? The old driver teaches you to use it correctly, save fuel and do not hurt the car.

If you drive in the urban area, the car is often filled with the smell of car exhaust, and you will feel dizzy and chest tightness when driving in an open place or on the highway for a long time.

First of all, let's explain, what is the outer circulation and what is the internal circulation?

1. External circulation: replenish fresh air.

The external circulation state is to use the fan to suck the air outside the car into the car, that is to say, the air channel outside the car and the inside of the car are circulating, and the air from the fan comes from outside the car. Sometimes I feel that there is still wind when the fan is turned off, because the owner has set up the external circulation. When driving in the city and encountering congestion, the car will be filled with tail odors, which is caused by the use of external circulation.

2. Internal circulation: block dirty air.

The internal circulation state is to close the airflow channel inside and outside the car, there is no airflow circulation without turning on the fan, and the airflow inhaled when the fan is turned on only comes from the inside of the car, forming the airflow circulation inside the vehicle. The internal circulation is mainly to prevent external dust and harmful gases from entering the car in a timely and effective manner, such as blocking the harmful exhaust gas discharged by the vehicle in front of it through smoke, dust, odor areas or when the vehicle is driving densely and compactly. Another function is heat preservation.

So when to use the outer loop and when to use the inner loop?

1. If the external air quality allows, it is recommended to use external circulation, because there is no reason to refuse fresh air.

1) If you drive at high speed for a long time, you will feel that the air in the car is turbid, people are uncomfortable, and you can't open the window, so you should use the external circulation to get some fresh air in;

2) If you feel too hot when you send the heater, you can turn off the fan and turn on the external circulation, which not only maintains the temperature in the car, but also has fresh air, which will make you feel more comfortable.

2. In the following cases, it is recommended to use internal circulation.

1) When the traffic is jammed, the internal circulation can prevent the exhaust gas from entering the car;

2) If the air conditioner is turned on to quickly reduce and increase the temperature in the car, it is recommended to open the internal circulation, and the external circulation can be turned on at an interval to replace some fresh air;

3) It is best to set the parking to the internal circulation state, because in the external circulation state, the dust blown by the wind is easy to enter the car, so that the dust in the car increases;

4) When turning on the air conditioner in summer or the heater in winter, the internal circulation should be used in order to maintain the temperature in the car, but the external circulation should be turned on from time to time to replace the air in the car.

Of course, the use environment and usage of different users will be different, and if you understand the core meaning of internal and external circulation, you can use it flexibly!

I hope it will be helpful to you, from the practitioners of Zhanjiang Jinfu Automobile.

Automatic air conditioning means that the temperature is controlled by a computer, and it allows your car to adjust the temperature to the temperature you set as quickly as possible!

Manual air conditioning means that you can regulate the temperature completely on your own!

The difference between automatic air conditioning and manual air conditioning: after the automatic air conditioner is turned on, it will automatically sense the temperature in the car, and will automatically stop running or reduce the cooling capacity to maintain a constant temperature in the car after reaching the set temperature.

There are now three main forms of automotive air conditioners: manual, electric, and automatic.

1. The wind speed, air volume and temperature of each tuyere of the manual air conditioner are realized by the mechanical structure, compared with the other two air conditioners, the feel of the manual air conditioner is slightly worse, and the feeling of the gear is limited by the mechanical situation. In addition, the appearance is slightly worse, but ** relatively cheaper.

2. The electric air conditioner is to replace the connection part between the control panel and the air conditioning host with electronic control, and the implementation principle is basically the same as that of the manual, but the control accuracy is more accurate, but the cost is higher. Now electric air conditioners are generally not installed separately, and most of them need to add an auto button, which is what you call automatic air conditioning.

3. Automatic air conditioning by the air conditioning system sensors (indoor temperature sensor, outdoor temperature sensor, air outlet sensor, water temperature sensor, sunlight sensor, air quality sensor, etc.), air conditioning computer, actuator (servo motor, blower, etc.), from the signal collection, input, processing, to the control of the compressor, the control of the air volume of the blower is automatically operated by the whole system, without the manual operation of the driver, ECU will automatically adjust the temperature, wind speed, humidity according to the actual environment, Generally, it is equipped on mid-to-high-end cars.

Automatic air conditioning is the trend of automobile development in the future, air conditioning according to the interior temperature, humidity, personnel, etc. independently judge and adjust the indoor air quality, so that the car is always in the comfort zone of the human body, closer to humanization.

The difference between automatic air conditioning and manual air conditioning of a car: 62616964757a686964616fe4b893e5b19e31333366303134

1. Automatic air conditioning is the function of automatically sensing the temperature through the temperature sensor inside and outside the car, evaporators and other equipment, and finally communicating to the air conditioning control system, automatically controlling the size of the air volume and the level of temperature. Provide more reasonable constant temperature and air volume, without the driver to operate back and forth, improving driving safety.

2. Automatic air conditioning is more convenient than manual air conditioning, more intelligent to use, when you feel that the temperature in the car is not suitable, you only need to re-set it, the car has a temperature sensor, once the temperature in the car reaches the temperature you set, the air conditioner will automatically stop working, and then start when the temperature changes, avoiding the trouble of manual air conditioning back and forth. In contrast, automatic air conditioners are more convenient and intelligent to use.

3. If the car is equipped with a more advanced dual-zone constant temperature air conditioner, each air conditioning outlet can be controlled separately, and the temperature and air volume of each air conditioning outlet can be adjusted. Dual-zone climate control allows every passenger in the car to adjust to their own temperature. The driver can see the temperature and air volume in the car at any time through the display panel of the air conditioner.

Automotive air conditioning and refrigeration system structure.

Compressor: Assembled on the engine, driven by the engine belt, the gaseous refrigerant at low temperature and low pressure is compressed, and the gaseous refrigerant with high temperature and high pressure is output.

Condenser: Integrated with the engine radiator (water tank), it is the main refrigerant storage site. The gaseous refrigerant, which has been heated and pressurized by the compressor, is transferred through the air conditioning duct to the condenser, where it is carried away by the cold air flowing through (from the fan and from the air intake grille), and at a certain point, the gaseous refrigerant begins to become liquid.

In this process, the gaseous refrigerant at high temperature and pressure becomes a liquid refrigerant at medium temperature and high pressure.

Throttle valve or expansion valve: Installed in the air-conditioning pipeline, the throttling effect makes the liquid refrigerant at medium temperature and high pressure become a liquid refrigerant at low temperature and low pressure.

Evaporator (box): generally installed under the instrument panel on the passenger side, the low-temperature and low-pressure liquid refrigerant after passing through the throttle valve is further cooled and depressurized, so as to promote it to become a low-temperature and low-pressure gaseous refrigerant. This is the most critical step in air conditioning refrigeration:

In this process, the evaporation box will absorb the heat of the surrounding air, so as to reduce the temperature of the surrounding air, and then blow the cold air out of the air outlet through the blower, so as to air conditioning and refrigeration.

Drying bottles: In the past, cars had separate drying bottles, but now many car drying bottles are combined with condensers, which are used to filter dirt and absorb moisture in the air conditioning system.

Finally, summarize the process of air conditioning and refrigeration: the gas at low temperature and low pressure becomes a gas at high temperature and high pressure through the compressor, becomes a liquid at medium temperature and high pressure through the condenser, becomes a liquid at low temperature and low pressure through the expansion valve, becomes a liquid at low temperature and low pressure through the evaporation tank, and refrigerates the next cycle in this process.

R-22 alternative refrigerants are R410A, R407C, such as Japan's room air conditioner (RAC) uses R410, and in 2000, more than 10% of room air conditioners have been replaced by HFC. This is not much in China, the current air conditioning and refrigeration industry is generally R22, the main reason is that R22 has superior physical characteristics and refrigeration performance in the air conditioning temperature zone, and the performance is stable, the technology is mature, the first is cheap, the older air conditioners are used R12, R22 is in recent years to replace R12. Ordinary domestic cars also use R12, but high-end cars mostly use R134A refrigerant, and their interface parts use looper quick change joints, and the joints are divided into sizes, and there are no threads on the surface.

At present, ordinary automobiles still use R12 refrigerant, and their interface parts are generally 2 identical check valves, and the connection thread is 7 16, and the inch thread of 20 teeth per inch is used.

The fluorine refrigerants used in the refrigeration industry are R11 (CFCl3), R12 (CF2Cl2), R22 (CHF2Cl), R32 (CH2F2), R113 (C2F3Cl3), R114 (C2F4Cl2), R115 (C2F5Cl), R123 (C2HF3Cl2), R125 (CHF2CF3), R134A (CH2FCF3), R143A (CH3CF3), R141B (CCL2FCH3), R142B (H3C2F2Cl), R152 (CH3CHF2), R404A (44% R125 and 52% R143A and 4% 134A), R407C (23% R32 and 25% R125 and 52% R134A), R410A (50% R32 and 50% R125), R500 (R12 and R152), R502 (R22 and R115), etc.

Although they are all fluorine, especially the working pressure of R12 and R22 is different, the pressure of the expansion valve is also different. Or don't mix them.
