How to clean the car air conditioner?

Cleaning method of automobile air conditioner 1. Why should we clean the car air conditioner?

During the operation of the automobile air conditioner, 80% of the tiny dust and bacteria in the air enter the air conditioner through the filter screen, and then stick to the evaporator after bonding with the condensed water, which affects the refrigeration and heat dissipation of the air conditioner. Because the humid environment and dust on the surface of evaporation box and ventilation duct provide a hotbed for the growth of mold and fungi, it produces the rotten smell of objects, which will pollute the whole carriage with the opening of air conditioning and be inhaled into human body, resulting in? Car air conditioning disease? Affected by dirty air conditioning, drivers are prone to dizziness, fatigue and nausea, and lead to respiratory diseases, such as tonsillitis, tracheitis and pneumonia.

Legionella found in 1976 is the most harmful lung disease caused by air conditioning. Old people and children with poor resistance may get sick because the car air conditioner is not clean.

In different road environments, dust, exhaust gas and pollen will pollute the air inside the car. A large amount of dust accumulates in the air duct of automobile air conditioner, which keeps it moist and warm all the year round. It is the most suitable place for bacteria to breed.

When passing through the evaporator, the water vapor in the air will condense into water droplets. Under normal circumstances, water will flow to the bottom of the shell of the air-conditioning heating device, wash away the dust attached to it, and discharge it out of the car through the conduit. If cars often drive in dusty places, all impurities and dust in the air can't be washed away by the water on the evaporator blades, and slowly accumulate on the evaporator blades, becoming a hotbed for mold growth. When the air conditioner is on, there will be a musty smell in the car. At this time, it is necessary to clean the air duct, evaporator and intake filter device of the air conditioning system to eliminate the pollution source and ensure the clean air in the car.

At present, people's concept of cleaning air conditioners still stays on cleaning or replacing air conditioner filter elements, but in fact, dirt and various bacteria (staphylococcus, Legionella, Aspergillus, influenza virus, etc. ) hidden in the gap of the aluminum sheet of the evaporation box, seemingly not hidden in the air conditioner at all, and continues to enter the air inside the car through the circulating airflow. Being in such an environment for a long time will make you feel dizzy, sleepy, uncomfortable and susceptible to infection.

Second, how to judge whether the air conditioning system of a car needs cleaning?

1. When the air conditioner is just turned on, when the blowing wind is not completely cooled or heated, it will give off a musty smell and a smoky smell.

2. When cooling or heating, the air blown out from the tuyere is not fresh, accompanied by sour smell or other peculiar smell.

3. The cooling effect decreases and the fuel consumption increases. Because the evaporation box has not been cleaned for a long time, there is too much dirt, which affects the cooling.

4. When people are in the car, they feel uncomfortable in the nose, trachea and lungs, or accompanied by cough and chest tightness.

5. After the vehicle has been used for more than one year, the air conditioning system has not been cleaned and maintained.

Third, how to clean the air conditioner?

1, manual disassembly and cleaning

In this method, the accessories such as instrument panel, glove box and directional column assembly need to be disassembled first, and then the snow seeds are drained, and then the air conditioner evaporator is taken out for washing and cleaning, and then the disassembled parts are reinstalled. This method is time-consuming and labor-intensive, which will increase the maintenance cost and cause some plastic parts to be damaged.

2. Use air conditioning cleaning agent for disassembly-free cleaning.

Lichiduo air conditioning cleaning agent: (disassembly-free cleaning)

Clean air conditioning ventilation system and filter efficiently. It can go deep into the evaporator of air conditioner and remove dust, oil stain, insect stain and other sundries in air conditioner system. Eliminate odor, kill bacteria and viruses, drive away allergens, prevent bacteria from breeding, emit pleasant fragrance and improve refrigeration effect. It is recommended to clean it once a year.

How to use:

After starting the engine, open the window, turn on the AC switch, adjust the air conditioner to the lowest temperature, and adjust the air intake mode to external circulation. Shake it evenly with a matching thin tube, intermittently spray and circulate the air inlet, continuously clean the air conditioner for 5- 10 minutes, then turn to internal circulation and circulate for 5 minutes. Finally, turn the fan to high speed and turn on the external circulation to discharge impurities.

It is also difficult to completely stop the growth of this mold in the shell. However, the owner can still keep the fan running for a few minutes after turning off the air conditioner to speed up the drying of the evaporator shell, thus keeping the air conditioning system relatively dry and reducing the chances of bacteria breeding in humid environment.

Fourth, the refrigeration situation.

1, as snow for air conditioning refrigeration (also known as? Coolant? When will it be replaced?

Experts point out that cars are mostly used now? Environmental protection snow species? Generally speaking, it should be replaced every 3 to 5 years. When you feel that the air conditioner is not cold enough and there is enough snow, you should consider changing the snow.

Liqiduo Snow Species R 134-a: (Environmental Snow Species)

Lichiduo environmental protection xuezhong

Made of high-quality raw materials and advanced manufacturing technology. The purity of this product is 99.8%, which is an environmentally friendly refrigerant with excellent refrigeration effect. It can protect the refrigeration system from corrosion and has no pollution to the environment, and can be widely used in various automobile air conditioners and refrigerators.

How to use:

Vacuum and check that there is no leakage, and then add refrigerant directly.

Through the above introduction, I believe everyone has a general understanding of the air conditioning system. Before using the air conditioning system, please remember to clean and maintain it to ensure that your car will accompany you through the hot summer in a healthy and cool environment.
