Air conditioning maintenance of new energy vehicles

In vehicle maintenance, it is easy to ignore the cleaning of car air conditioners, but in fact, it needs cleaning more than the air conditioners used in our homes and companies.

If it is not cleaned for a long time, not only will the cooling and heating effect of the air conditioner become worse, but also mold will be generated, which will follow the air circulation in the car into the body, causing respiratory discomfort and affecting health.

Therefore, it is very necessary to clean the air conditioner once or twice a year.

{Is it really necessary to clean the air conditioner every year?}

As it is cold and humid in spring, it is easy to breed bacteria. In order to avoid normal use in summer, it is recommended to thoroughly clean the air conditioning system in spring. What benefits will air conditioning cleaning bring?

1. Improve the cooling and heating effect. The cleaned air conditioner is free of dust and dirt, and the air flow exchange is smooth, so the cooling effect will be significantly enhanced.

2. It is beneficial to health. After cleaning, it not only greatly reduces the incidence of "air conditioning syndrome", but also purifies the air in the car and the breeding bacteria, reduces the occurrence of respiratory diseases, maintains the environment in the car, and greatly improves driving comfort.

3. Reduce vehicle fuel consumption. After cleaning and maintenance, the operating efficiency of the air conditioner is improved, which reduces the energy consumption of the air conditioner, thus reducing vehicle fuel consumption and virtually saving the cost of using vehicles.

Air inlet of air conditioner is clean

Check the air inlet of the air conditioner to see if there is any deposit at the air inlet of the air conditioner. Clean the dust and sundries with fan and soft brush.

Air conditioning filter element replacement

The service life of an original air conditioning filter element is one year or 30000 km. Clean the A/C filter frequently to ensure fresh air in the car. The filter element of the new energy charging post cannot be washed with water, and can be cleaned with an electric hair dryer at ordinary times. If the filter element is too dirty, it needs to be replaced in time.

Blower cleaning

The automobile blower is the fan of the air conditioning system. The air blower sucks out the air in the vehicle, forcing the airflow through the evaporator to bring the heat generated when the liquid refrigerant in the evaporator evaporates into the vehicle. Make the temperature rise to warm up. Long term use will lead to the accumulation of a large amount of dust on the blower, emitting odor.

Evaporator cleaning

The cold air of the air conditioner is generated by the operation of the evaporation box, and the continuous evaporation of the refrigerant will cause water droplets on its surface. Dust is attached to the evaporation box through the blower, which is easy to mildew and affect health if accumulated for a long time.

To clean the blower, the air conditioning system in the vehicle needs to be removed. After taking out the blower, use professional cleaning agent to clean it.

Cleaning the evaporation tank requires a special visual cleaner to clean the evaporation tank of the air conditioner in depth.

Through the front camera and nozzle of the washer, every corner of the evaporation tank can be accurately cleaned.

Air conditioning evaporation box

The air conditioning evaporation box is an important component in the vehicle air conditioning system, which is often ignored during maintenance, resulting in abnormal air conditioning smell or poor cooling effect. How to do reasonable maintenance?

Function of air conditioning evaporation tank cleaning: New energy vehicle maintenance

It is very important to clean the evaporating box of the automobile air conditioner regularly. If it is not cleaned for a long time, the dust and dirt in the evaporating box will affect the efficiency of the air conditioning system, and even affect the health of the driver and passengers.

Cleaning cycle:

Cleaning cycle:

It is generally recommended to clean once a year or every two years to ensure the normal operation of the air conditioning system. When using the air conditioner, if there is a peculiar smell or the cooling effect of the air conditioner becomes worse, the evaporation box should also be checked and cleaned in time.

How to clean:

The common cleaning agents for evaporation tank mainly include spray type and injection type.

The spray type cleaning agent can be directly sprayed to the air inlet of the air conditioner, and the cleaning agent can be sent into the evaporation box through air circulation. The cleaning effect is good. Injected detergent requires professionals to use special equipment to inject detergent into the air conditioning system and clean each component one by one. The cleaning effect is more thorough, but the price is higher.
