Cleaning and antibacterial strategy

Summer car air conditioner cleaning and antibacterial strategy

In summer, it is the season of frequent use of car air conditioners. It is necessary to do a cleaning project of car air conditioners before frequent use of car air conditioners, to avoid air conditioners from malfunctioning, to prevent bacteria and viruses from breeding in air conditioners, and seriously injure car owners. health, affecting normal use. Liangche will recommend summer car air conditioning cleaning and antibacterial strategies for car owners.

Car air conditioners are easy to accumulate bacteria

Automobile air conditioner evaporators, fans, etc. have been in a closed and dark state for a long time, and the internal environment is high temperature and humid. After the impurities, dust, bacteria and viruses in the air enter the interior of the air conditioner, they will bond with the condensed water and block the evaporator and other components. Over time, a large amount of dirt, nicotine, mold, fungi, etc. adheres to it.

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 change of system pressure. It consists of evaporation box, expansion valve, compressor, blower, condenser, drying tank and pipeline. When the air-conditioning system is working normally, the evaporating box works in a cold environment, and water will be produced when it encounters the relatively hot air from the outside. This is also the reason why the water pipe is designed in the structure of the evaporating box; Surface dust provides a breeding ground for mold and fungus.

Enclosed small spaces are prone to inhalation of germs

Mold and fungus will quickly multiply into mold clusters and fungal clusters, producing rotten odors of organisms. These odors will be mixed with the air-conditioning when the air conditioner is turned on, contaminating the entire interior of the car, and often making drivers and passengers feel uncomfortable. People with allergies may feel it more deeply.

After a long winter and spring, when we start to use the car air conditioner again in summer, harmful germs will be blown out of the air conditioner and inhaled into the human body in the closed and narrow space in the car, which will lead to "car air conditioner disease". "All kinds of symptoms; improving the air in the car and improving the efficiency of air conditioning and refrigeration are what every driver should pay attention to.

Aerosol cleaning air conditioner to keep germs away

In summer, before using the air conditioner, it is recommended that the car owner clean the air conditioner pipeline and evaporation box. The air conditioner cleaning methods on the market include foam type and spray type.

The fom-type cleaning method is to spray the foam-type cleaning agent directly into the air-conditioning pipeline, and clean it by blowing the foam to adhere the dust, but it is difficult to completely adhere to many dirt, and the foam adheres to the pipe wall and easily adheres to the dust, forming two secondary pollution.

Another spray type is the car air conditioner-free cleaning technology, which sprays the liquid medicine on the air conditioning pipes in the car. The advantage of using this method is that the liquid medicine can be evenly sprayed on the places where the blower wind can blow, and it can be quickly removed. The dust, grease, mold and other pollutants adhered to the air conditioner evaporator, filter, condenser, pipeline and other components can achieve the purpose of cleaning, sterilization and antibacterial, avoid secondary pollution, and form a protective film to inhibit mold regeneration. The most important thing is to form a good car use and maintenance habits, the combination of prevention and treatment is the best.

The harm of car air conditioner odor

The odor of car air conditioners is not just unpleasant. It has been proved by a large number of experiments that water vapor adheres to the evaporator of the air conditioner, and at least three kinds of molds harmful to human health will be produced: Aspergillus, Yin mold and Penicillium. Although there are few complaints about car air conditioners around us, medical trials have shown that these molds may be harmful to the human body in seven ways: causing headaches, fever, sudden sore throat, tonsil infection, asthma, Side effects such as flu symptoms, dermatitis, and difficult-to-heal wounds.
