Does a car air conditioner need to be maintained? Does the car air conditioner need regular maintena

1. Slow down the air conditioner for a long time under the scorching sun.

In summer, the car parked under the scorching sun, the temperature in the car may be as high as sixty or seventy degrees Celsius, at this time, the doors and windows should be opened first, you can use a fan for ventilation first, wait for two or three minutes after the hot air is discharged before sitting in and start the car, and do not rush to close the window, first open the air conditioning external circulation, and then close the window when the temperature inside and outside the compartment is similar, and then close the window to enable the internal circulation. This not only reduces the load of the air conditioner, but also allows the air conditioner compressor to quickly enter the working state.

2. Don't open it for too long.

We know you're "not short of money", but we encourage you to turn off the air conditioning appropriately while driving. Using an air conditioner for a long time can cause excessive condenser pressure, which can cause wear and tear on the refrigeration system. So, if the temperature in the car is already comfortable for you, you might as well turn off the air conditioner for a while and let it rest for a while.

3. Be cautious in air conditioning modification.

It is not advisable to modify the car's air conditioner, because the original air conditioner is matched with the car's engine, and if it is modified at will, it will affect the performance of the car.

4. The temperature of the air conditioner should not be too low.

Don't set the temperature of the air conditioner too low and don't let the wind speed be too small. The temperature difference between the inside and outside of the general compartment of automatic constant temperature air conditioning should not exceed 10. For non-thermostatic air conditioners, you can first set the temperature of the air conditioner to the lowest and turn the wind speed to the maximum, and then turn the temperature up a little when it feels cold, and lower the wind speed by one gear.

5. Properly turn on the large air volume.

Generally, the higher the air conditioner is turned on, the louder the noise will be. Many car owners will always use a small windshield because they are afraid of noise, but this is not good for air conditioning in the long run! Because the air conditioner will suck in a lot of dust when it is used, the easiest way is the most effective way to blow out the floating dust on the inner surface of the air duct by turning on the air duct regularly.

6. Control the direction of the air outlet.

When refrigerating, the wind direction of the air conditioner is best to blow upward, because the cold air will sink downward, the wind direction gear is best to choose the blowing surface block, adjust the air outlet upward effect is the best, do not choose the windshield of the gear, because the temperature of the windshield is very high, will offset a large part of the refrigeration effect.

Yes. It is indicated in the car factory manual that the refrigerant and refrigerant oil of the car air conditioner need to be replaced every two to three years 2113, but now many car owners and even repair shops have ignored this question 5261. In fact, during the operation of the air conditioning system, the refrigerant oil will slowly deteriorate to produce acidity, water 4102 points, and oil pollution, resulting in the system working in an unhealthy state, the lubrication becomes poor, and the system is dry grinding, at this time, the air conditioner is refrigerated according to the old 1653, and once the air conditioner is not refrigerated, it means that a certain part of the air conditioning system may have been damaged, so that we need to spend more time and money to inspect and repair our car.

Regular replacement of refrigerant oil and related high-efficiency and environmentally friendly refrigerants will prolong the service life of the air conditioner and reduce the occurrence of failure, so it is necessary to maintain the air conditioning system regularly.

Maintenance methods of automobile air conditioners: 1. Regularly check refrigerants and refrigeration oil; 2. Clean the surface of the condenser; 3. Clean the surface of the evaporator. The automobile air conditioning device, referred to as the automobile air conditioner, is composed of a refrigeration system, a heating system, a ventilation and air purification device and a control system.

The functions of automobile air conditioning are: 1. Adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in a better state, provide a comfortable riding environment for the occupants, and reduce fatigue during the journey; 2. Create good working conditions for the driver and play an important role in ensuring safe driving.

When the air flows through the cold air-conditioning evaporation box, the water vapor in it is easy to condense in the evaporation box, which causes the evaporation box to be in a humid environment for a long time, resulting in the dust and particles in the air being more easily adsorbed on its surface, easy to breed bacteria, fungi or other microorganisms, threatening the health of the personnel in the car, with the continuous accumulation and deterioration of pollution, the air conditioning system will also produce unpleasant musty smell or other peculiar smells, which will have a great impact on the health of personnel, and in severe cases, it will also cause allergic reactions to the human body, such as headaches, Symptoms such as rhinitis and itchy eyes. Mercedes-Benz aircon cleaning service can completely remove dirt, bacteria and the resulting fishy and musty smell in the air conditioner, and return healthy air in the car!

In the case that the car has the automatic cleaning function of the air conditioner, the owner can press the "auto" button to turn on the air conditioner, and at this time, the outdoor air will enter the car after being filtered by the air conditioning filter. When encountering air pollution, if you open the door or window, the dirty air will enter the car, at this time, close the door and window and press the "inner circulation" button, let the air conditioning system and air conditioning filter deeply purify the air in the car for 5-10 minutes, the harmful gases in the car and the bacteria content in the car will be significantly reduced.

Therefore, in order to protect the health of the people in the car, it is recommended that the car owner regularly clean the air conditioning system and replace the cabin air filter, so as to enjoy the healthy and fresh air like a forest!

<> "The air conditioner of the car also needs to be maintained.

1. Check the hose of the air conditioning system.

Check the aging of the hoses of the air conditioning system, if the inspection is not timely, then there will be a burst of pipes, which will cause the leakage of refrigerant and refrigeration oil.

2. Use of air conditioners in the spring cold.

In the spring, when it is warm and cold, the ambient temperature generally fluctuates between 0 and 20 degrees. During this period, the air conditioner should be turned on in ECON mode, the temperature should be set to 21 to 22 degrees, and only blow down to the "" external circulation, and the air conditioner should not be turned off when parking.

This can not only ensure that the temperature in the car is pleasant, but also make the air in the cabin fresh, and because the compressor is not running, the impact on fuel consumption and power is very small.

3. Summer judgment.

Summer is the peak time for air conditioning. Due to the huge temperature difference between the inside and outside of the car after turning on the air conditioner, it is easy to cause the air conditioning system to mold and breed mold, therefore, the owner should turn off the air conditioner and turn on the natural air a few minutes before getting out of the car, so that the temperature in the air conditioning pipe rises and eliminates the temperature difference with the outside world, so as to keep the air conditioning system relatively dry.

4. Comprehensive inspection.

In order to maintain the good performance of the car air conditioner, it is very necessary to do a comprehensive inspection of the car air conditioner on a regular basis, and check the cleanliness of the condenser and steamer in time.

If there is a lot of dust, it should be cleaned, and the performance of the air conditioning switch and control components should be checked to see if the performance is normal, and whether the refrigerant is sufficient. Routine inspections and maintenance help to ensure that the vehicle's air conditioning is in good condition.

Hello, how to maintain the car air conditioner in summer?

1. Outdoor parking in summer, the sun is quite fierce, and the parking time is long under the scorching sun, so do not use the air conditioner immediately after the vehicle starts. First open all the windows, start the external circulation, exhaust the hot air, and wait for the temperature in the cabin to drop, then close the windows and turn on the air conditioning.

Second, in order to save fuel, some car owners turn off the air conditioner when they get out of the car and go to the toilet. Therefore, the air conditioner will be turned on and off frequently, which is not right, because it is easy to damage the air conditioning system.

3. For daily driving, turn off the air conditioner a few minutes before parking, turn on the natural air later, and make the temperature in the air conditioning duct rise before parking to eliminate the temperature difference with the outside world, so as to keep the air conditioning system relatively dry. Avoid the growth of a large number of molds due to moisture.

Fourth, the use of air conditioning after parking should not be too long, which can easily lead to the increase of carbon monoxide concentration in the car and poisoning.

5. During the use of the automobile air-conditioning system, the surface of the small water tank of the blower, refrigeration system evaporation box and heating system accumulates a lot of dust, moisture, bacteria and other dirt, which causes damage and allergic reaction to the human respiratory system and the air conditioning system, and the air-conditioning system itself will also cause faults such as poor refrigeration effect and small air output. So, in general, the cabin air filter is cleaned every 5,000 km or 3 months, and the cabin air filter is replaced every 20,000 km or 12 months.

Method 1: Inspect the air conditioner thoroughly.

When using the air conditioner for the first time in summer, you should first check the air conditioning system, such as checking whether the refrigerant and air conditioning filter are too dirty through the liquid storage tank, and whether the radiator has foreign objects.

Method 2: Pay attention to the cleaning of the air conditioner.

Some novices always have to wait until the air conditioner is not working well before thinking of cleaning the air conditioner, which is not right. The air conditioner filter should be replaced regularly, because there is a lot of sand and dust in Beijing in spring, and catkins are flying, which will stick to the filter, which is easy to breed bacteria and make the air conditioner produce musty smell, so it is best to replace it once a year after spring. In addition, the condenser should also be cleaned regularly, and the water tank should be removed to clean it thoroughly.

Method 3: After parking, do not turn off the air conditioner yet.

After arriving at the destination, the owner usually closes the air-conditioned car door and leaves directly. Unlike autumn and winter, the huge temperature difference between the inside and outside of the car during the hot summer months can cause mold to grow in the air conditioning system, which in turn can breed mold. Therefore, the owner should turn off the air conditioner a few minutes before arriving at the destination, turn on the natural air, make the temperature in the air conditioning duct rise, eliminate the temperature difference with the outside world, so as to keep the air conditioning system relatively dry and avoid mold reproduction.

Method 4: Open the large air volume regularly.

Some car owners rarely or never turn on the air conditioner to high air volume because they don't like the noise made when the air conditioner is turned on to high gear. However, the air conditioner will suck in a lot of dust when it is used, and it is a simple way to keep the air conditioner clean by turning on the wind energy regularly to blow out the floating dust on the inner surface of the air conditioner. In addition, it is necessary to sterilize, clean and remove odors with a special air duct cleaning solution.

1) Try not to use air conditioning when driving at low speeds.

When you encounter a traffic jam while driving, do not run the engine at a higher speed to improve the efficiency of the air conditioner, as this will adversely affect the service life of both the engine and the air conditioning compressor.

2) It is not advisable to leave the air conditioner on for a long time in summer.

Using the air conditioner for a long time in the summer will cause the condenser pressure to be too high, which will cause wear and tear on the refrigeration system, because the air conditioner is a heavy burden on the engine, and the engine itself is a heating element, let alone in the hot weather in summer. Some small displacement cars even have water boiling in this situation, which affects driving and reduces the efficiency of air conditioning. Therefore, the air conditioner should not be used for too long each time, if the temperature in the car has reached a comfortable temperature, you can turn off the air conditioner and turn it on again after a while.

3) Turn off the heat before turning off the air conditioner.

Some car owners often remember to turn off the air conditioner after turning off the engine, which is harmful to the engine, because in this way, when the vehicle starts the next time, the engine will start with the load of the air conditioner, and such a high load will damage the engine. Therefore, the air conditioner should be turned off and then turned off after each stop, and the air conditioner should also be turned on after two or three minutes of starting the vehicle and the engine has been lubricated.

The maintenance to be done for the car air conditioner is:

1. Replace the air conditioner filter;

2. Clean the air outlet of the air conditioner;

3. Maintain the air conditioning condenser.

Ways to use air conditioning wisely:

1. Turn off the air conditioner when driving at low speed;

2. Do not smoke when the air conditioner is turned on in the car;

3. Turn off the heat first and then turn off the air conditioner;

4. Start the internal circulation immediately when entering the car in summer.

The way to use the car air conditioner is:

1. Turn on the AC switch;

2. Adjust the air outlet selection knob, blow the air outlet upwards when the air conditioner is turned on, and blow the air outlet downward when the heating is turned on;

3. Adjust the wind speed switch;

4. Adjust the air internal and external circulation conversion knob;

5. Adjust the knob for switching between cold and warm.

Replace the air conditioner filter, clean the air outlet of the air conditioner, and maintain the air conditioner condenser. Turn off the air conditioner when driving at low speed, do not smoke when the air conditioner is turned on in the car, turn off the engine first and then turn off the air conditioner, and start the internal circulation immediately when entering the car in summer.

Refrigeration system: Cooling or dehumidifying the interior air or fresh air entering the interior from the outside, so that the interior air becomes cool and comfortable.

1. Do not adjust the direction of the air outlet of the air conditioner at will. The air conditioning vent should be reasonably adjusted. According to the principle that the cold air sinks and the hot air rises, the air outlet should be turned up when the air conditioner is turned on, and the air outlet should be adjusted downward when the heating is turned on.

2. Start the air conditioner regularly in winter. Some places may not require the use of air conditioning in winter. The long-term use of the air conditioner will lead to the aging of the rubber ring, and the lubricating oil on the internal parts of the air conditioner will also dry out, so it is necessary to start the air conditioning equipment frequently and regularly to ensure the lubrication of the air conditioning equipment, so that it can be maintained in good condition, and it is recommended to start it once a week in winter.

3. The use of air conditioning should not be too long. The use of the air conditioner for a long time will make the condenser pressure too large, which will have a large loss of the refrigeration system, so each time the air conditioner is used for too long, if the temperature in the car is already more comfortable, turn off the air conditioner for a while, and turn it on after a period of time.

4. In summer, drive first to ventilate and cool down, and then open the internal circulation. Because the temperature inside the car is higher than the temperature outside the car, it is recommended to open the windows for ventilation to cool down and exhaust all the hot air in the car first. After the temperature in the cabin drops, the air conditioner is converted to an internal cycle.

5. It is not advisable to use the air conditioner for a long time for internal circulation. Because the internal circulation is the circulation of air in the enclosed space in the car, the oxygen content in the car will continue to decline, and if the gasoline in the cylinder is not completely burned, the unburned carbon monoxide of the engine may also leak into the cabin, so the air quality in the car will become worse and worse, and even harmful to the human body. Therefore, the internal circulation should be opened for a while, and then the external circulation should be opened for a while to allow fresh air to enter the cabin.

You can't sleep in the car with the internal loop on, and that's the same reason.
