What is the main cleaning of car air conditioner cleaning?

Air conditioning is the channel for air communication between the inside and outside of the car, and the air conditioner is easy to breed bacteria, and frequent cleaning not only helps the beauty of the car, but also is beneficial to the health of the driver and passengers. Tips: Automobile air conditioners, evaporators, fans, etc. are in a closed and dark state for a long time, and the internal environment is high and humid.

After the impurities, dust, bacteria, and viruses in the air enter the air conditioner, they are bonded with condensate and blocked on the evaporator and other parts. Over time, a large amount of dirt, nicotine, mold, fungus, etc. are adhered to. This situation is mainly caused by the structural characteristics of the air-conditioning system itself, the air-conditioning system mainly uses fluorine or 134A as the medium, and the purpose of refrigeration is achieved through the transformation of system pressure.

It consists of an evaporation tank, an expansion valve, a compressor, a blower, a condenser, a drying tank, and a pipeline. When the air conditioning system is working normally, the evaporation box works in a cold environment, and water will be generated when it encounters the relative hot air outside, which is also the reason for designing the water pipe in the evaporation box structure; The humid environment of the evaporation chamber and ventilation ducts and the dust on the surface provide a breeding ground for mold and fungus.

It is mainly to clean the air conditioning inlet pipeline, air conditioning filter, air outlet, fan blade, evaporation box, etc.

Air conditioning system outlet ducts.

Hello, cleaning dust, inhalable dust.

Automobile air conditioning system deodorization, cleaning, sterilization, taking Citroen Sega as an example of the detailed process.

When the air conditioner is cleaned, the parts to be cleaned include the air conditioning inlet pipeline, the air conditioning filter element, the air outlet, the fan blade, the evaporation box, the sponge grid, etc

1. If there is still a peculiar smell after cleaning the air-conditioning system, it means that there is dirt inside the evaporation tank or the air-conditioning pipeline, and the solution to this situation can only be to disassemble and clean the air-conditioning pipeline and evaporation box;

2、。When the air conditioner is working, the evaporator takes away the hot air in the room, and at the same time sends the cold air in, the water dripping out of the air conditioner is generated on the evaporator, although the evaporator is protected by a filter screen, but 80% of the dust will pass through the filter screen and adhere to the humid evaporator;

3. After the air conditioner is out of use, it is like dry cement, firmly stained on the surface of the evaporator, these places are the most likely to breed pathogenic bacteria and mites, and affect the normal heat exchange efficiency of the air conditioner, increase power consumption, and quietly Qing Tangerine Therefore, this is the part of the air conditioner that needs to be cleaned first.

1. Clean the car air conditioner with air conditioner cleaning agent.

In general, the car air conditioner has a pollen filter at the air inlet, and its function is to prevent external dust from entering when the car air conditioner circulates externally. When cleaning the air conditioner, remove the pollen filter and put the air conditioner foam cleaner into the air inlet, and close the air outlet of the air conditioner to avoid the foam cleaner from flowing out of the air outlet.

Next, start the car, turn on the air conditioner, and let the foam cleaner circulate in the air conditioning system, this step lasts for a few minutes to ensure that the foam cleaner circulates to the various channels of the air conditioning system. After about 5 minutes, the air conditioner is turned off and the car is turned off, and it will not be long before dirt will flow out of the air conditioner's duct system located in the chassis. This cleaning method is suitable for when the car air conditioner is not particularly dirty.

2. Disassemble and clean the car air conditioner.

Another method of cleaning the air conditioner is to disassemble and wash, which is much more troublesome than the first method, first you have to disassemble the dashboard and take out the evaporator of the air conditioner. The evaporator of the air conditioner that has not been cleaned for a long time must be covered with dust, and it needs to be carefully cleaned with a brush. After washing, put the air conditioner back on, and then use the first method to clean the air conditioner.
