In hot summer, car air conditioners must be maintained before use

The hot summer is coming, and the use of car air conditioners is becoming more and more frequent. Many riders also have headaches because of various problems with their car air conditioners, such as “the cooling effect is not good, and the problem cannot be solved after adding and changing the refrigerant”; ” The car has a lot of power, but the air conditioner is boring”; “When the air conditioner is just turned on and the wind blowing has not cooled down, it will smell a mildew-like sour odor, smoke and dust. If you stay in this environment for a long time, You will feel dizzy, nausea, lung discomfort, cough, dizziness, etc.” This is what is called “car air-conditioning disease” in medicine. If you stay in this sub-health condition for a long time, it will cause respiratory diseases if it is not prevented in time, which will seriously endanger the people’s health. So how can we effectively prevent car air-conditioning disease?

Causes

Car air conditioners are easy to accumulate bacteria

According to car maintenance experts, car air conditioners evaporate Appliances, fans, etc. have been in a closed and dark state for a long time, and the internal environment is hot 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.

Symptoms

Bacteria easily inhaled in confined spaces

Mold and fungi can quickly multiply into Mold clusters and fungal clusters produce 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, when we start to use the car air conditioner again in summer, harmful germs will blow out from the air conditioner and be inhaled into the human body in the closed and narrow space in the car, which will lead to “car air conditioner disease”. Various symptoms; improving the air in the car and improving the efficiency of air conditioning and refrigeration are what every driver should pay attention to.

Prescription

Aerosol cleaning air conditioner to keep germs away

Before using the air conditioner in summer, it is recommended that car owners To clean the air conditioning pipeline and evaporation box, the air conditioning cleaning methods on the market include foam type and spray type.

The foam cleaning method is to spray the foam cleaning agent directly into the air conditioning pipeline, and clean it by blowing foam to adhere the dust. Another spray type is the car air conditioner free cleaning technology, which sprays the liquid medicine on the air conditioning pipes in the car, and the place where the blower wind can blow can evenly spray the liquid medicine to achieve the purpose of cleaning, sterilization and antibacterial. And form a protective film to inhibit mold regeneration.

Professionals introduced that the most important thing is to form a good car use and maintenance habits, the combination of prevention and treatment is the best.
