When driving in hot summer, using the air conditioner is a must, and it is also a way to relieve the hot weather during driving. However, if the air conditioner is out of control, it is also very bad for the human body. Let's take a look at the misunderstandings in the use of air conditioners.

Misunderstanding 1: Turn off the air conditioner without turning off the air conditioner

When many people park, they often turn off the air conditioner without turning off the air conditioner, thinking that this is no problem. In fact, doing so will directly lead to a large number of molds in the air conditioner. Moreover, when the car is started again, the engine has to bear the ignition pressure of the air conditioner to start, so the high-load operation will bring great damage to it.

The correct way is:

A few minutes before you arrive at your destination, turn off the cold air from the air conditioner, open the windows to allow adequate ventilation, and then park your car. In addition, it is best not to use air conditioning after parking. Because when the engine is working, when the gasoline is not completely burned, high concentrations of carbon monoxide will be produced. If the internal circulation is used all the time, the air in the car will become more and more polluted, and there may even be hypoxia. It is recommended that car owners switch between the inner and outer loops every once in a while. Especially when parking, be sure to switch to external circulation to ensure fresh air in the car.

Myth 2: Just cleaning the air filter

It is unscientific to turn on the temperature of the air conditioner to the lowest level. Because the temperature is too low, it is easy to get arthritis, frozen shoulder, colds and other diseases. In a car exposed to the sun in high temperature in summer, the difference between the temperature inside the cabin and the outside temperature should be 5°C to 8°C, and the optimal temperature of the air conditioner can be controlled at about 27°C.
Many people know that air filters need to be cleaned and replaced. As everyone knows, the bacteria growing in the evaporation box of the air conditioner is a potential "health killer", and if it is not cleaned for a long time, it will lead to respiratory diseases.

The cleaning of the air conditioner evaporation box is divided into two steps:

The first step is to spray the evaporator cleaning agent into the air-conditioning drain pipe. This cleaning agent is in the form of foam. It takes about five or six minutes to spray all of it, but it takes half an hour for it to be completely digested in the air-conditioning pipe. Be careful not to start the vehicle or turn on the air conditioner when spraying the cleaning agent.

The second step is to sterilize the air conditioner, which is to spray the air conditioner bactericide into the blower of the car air conditioner. After spraying, the vehicle should be started normally for 15 minutes to sterilize the air conditioner.
