What practical tips for car air conditioner maintenance

Method 4: Regularly open large air volume. Some car owners rarely or never turn on the air conditioner to a large air volume because they don't like the noise made when the air conditioner is turned on to high gears.However, the air conditioner will absorb a lot of dust when it is in use. Regularly turn on the wind to blow out the dust on the surface of the air conditioner duct, which is a simple way to keep the air conditioner clean.

Car empty cleaning method: Car empty cleaning method Use air cleaner to clean the car empty. Most of the car airspace is basically equipped with pollen filters at the air intake, which is to prevent external dust from entering when the car airspace is adjusted to external circulation. When cleaning the empty, remove the pollen filter and put the empty foam cleaner into the air intake.

There are two ways to clean car air conditioners, one is to use air conditioner cleaner (disassembly-free). The other is to disassemble and clean the parts of the air conditioning system. Use air conditioner cleaner to clean the car air conditioner: Under normal circumstances, the air inlet of the car air conditioner has a pollen filter, which functions to prevent external dust from entering when the car air conditioner circulates outside.

How to maintain car air conditioner

1. Daily maintenance. Daily maintenance is mainly checked by looking, listening, touching and measuring. Use your ears and nose to check the car for abnormal noise and smell. Whether the operating state of the electric vehicle air conditioning system is reliable can also be judged by the indicated pressure of the pressure gauge group.

2. Tips for car air conditioning maintenance. People take care of themselves according to the changes in the weather, and cars are no exception. Air conditioning is an important part of the car. No matter the severe winter and heat, with air conditioning, the temperature in the car is always comfortable.

3. Adjust the direction of the air outlet, no need to adjust it at will. Some friends do not pay attention to adjusting the direction of the air conditioner when using the air conditioner, which is not conducive to the effect of the air conditioner. According to the principle that the cold air wind sinks and the hot air wind rises, the good practice should be that the air outlet should turn up when the air conditioner is turned on, and the air outlet should be turned down when the heater is turned on.

Maintenance 4: Regularly clean the condenser In order to ensure that the entire air conditioning system can work normally, it is very important to keep the surface of the condenser clean.Regular cleaning of the surface of the automobile condenser can make the heat energy generated by the vehicle spread to the outside world in a timely and convenient manner, especially regular cleaning of the surface of the condenser, which can greatly improve the refrigeration effect of the air conditioning system.

● Turn on the air conditioner in the car and try not to smoke. When the air conditioner is on in the car, the occupant should not smoke in the car. If you smoke, please adjust the ventilation control of the air conditioner to the external circulation position. It should also be noted that you should remember not to rest or sleep for a long time in an air-conditioned car.

When the external air temperature is suitable and there is no need for air conditioning cooling, the air conditioning system should be turned off. When the car is driving and the engine is idling, the air regulator should not be used for too long, so as to avoid excessive pressure on the refrigeration system, resulting in a reduction in the service life of the air regulator or local damage.

Car cleaning method empty adjustment: car maintenance empty adjustment empty adjustment air outlet direction, no need to adjust at will.Some friends do not pay attention to adjusting the direction of the air conditioner when using the air conditioner, which is not conducive to the effect of the air conditioner.

In this way, the air conditioning system can be kept relatively dry and the odor of the air conditioner can be reduced. Skill 2: Do a good job of cleaning the interior of the car. Cleaning and maintaining the air conditioner is not only about the air conditioner, but also the interior of the car. Due to the high temperature and humidity, all kinds of germs are very easy to grow in the car.

Car cleaning method empty adjustment: car maintenance empty adjustment empty adjustment air outlet direction, no need to adjust at will. Some friends do not pay attention to adjusting the direction of the air conditioner when using the air conditioner, which is not conducive to the effect of the air conditioner.

Car air conditioner maintenanceSkills: The cooling capacity of the air conditioner is not strong. For the air conditioner of the car, the most common problem we encounter is that after a winter, when we turn on the air conditioner, we find that the cooling capacity of the air conditioner has decreased; even the air outlet of some vehicles will blow hot air.

Tips for car air conditioning maintenance Regularly clean the air filter, generally once every two or three weeks. Protect the heat sink of the condenser and evaporator. The heat sinks of the condenser and evaporator are made of 0.15 mm aluminum sheets into copper tubes and inflated, which cannot withstand collisions. Protect the refrigeration system.

The maintenance method of automobile air conditioner: regularly check the refrigerant and refrigeration oil; adjust the pressure at the low-pressure end of the air conditioning system to 2 to 3bar, and the pressure at the high-pressure end to 15 to 25bar;Clean the condenser and clean the surface of the evaporator.

The daily maintenance of car air conditioners is mainly checked by looking, listening, touching, measuring and other methods. Check and clean the condenser of the car air conditioner, and the heat sink should be clean and there should be no blockages between the radiators. Check the amount of refrigerant in the refrigeration system.

Car air conditioner maintenance skills. Air conditioner refrigeration is not strong. For car air conditioners, the most common problem we encounter is that after a winter, when we turn on the air conditioner, we find that the cooling capacity of the air conditioner has decreased; even the air outlet of some vehicles' air conditioner will blow hot air.

Trick 1: Don't turn on the air conditioner when it's just starting up. On hot days, if the car is parked in the open air for a long time and exposed to the sun, the car will be very stuffy and the temperature will rise sharply. Therefore, many car owners will turn on the air conditioner and adjust the cold air to the maximum as soon as the car starts.

1. Method 4: Regularly open large air volume. Some car owners rarely or never turn on the air conditioner to a large air volume because they don't like the noise made when the air conditioner is turned on to high gears.

2. Check and clean the condenser of the car air conditioner. It is required to clean the heat sink and there are no blockages between the radiators. Check the amount of refrigerant in the refrigeration system.

3. The practice is to extract all the refrigerant of the air conditioning system and maintain a negative pressure of 1bar, and wait for 24 hours to see if the air pressure in the system is maintained at about -1bar.If the air pressure rises significantly, it means that there is a leak in the air conditioning system and further disassembly and inspection are required.

4. Clean frequently and replace the air conditioner filter regularly. Many friends can't wait to wash the car every 2 days, but don't pay attention to the maintenance of the car. There are often heavy rains in summer, and the weather is relatively humid. If the air conditioner filter is not cleaned in time, it will cause a strange smell and moldy smell in the car.

5. Car cleaning method empty adjustment: car maintenance empty adjustment empty adjustment air outlet direction, no need to adjust at will. Some friends do not pay attention to adjusting the direction of the air conditioner when using the air conditioner, which is not conducive to the effect of the air conditioner.

6. Under normal circumstances, the air inlet of the car air conditioner has a pollen filter, which functions to prevent external dust from entering when the car air conditioner circulates outside. When cleaning the air conditioner, the pollen filter should beTake off the device and shoot the air conditioner foam cleaner through the air inlet. At the same time, close the air outlet of the air conditioner to avoid the foam cleaner from flowing out of the air outlet.
