【Meiruier Filter】Eight misunderstandings of using automobile air filter

2023-02-24 View:

The car air conditioner is the close companion of the car owners, but if you don't understand it, the close companion will often play with his temper and even hurt the owner's body. Mrefilter pointed out eight major misunderstandings of using air conditioners to the majority of car owners.

The first mistake is that the air conditioner is on for a long time
Some car owners often turn on the air conditioner after getting on the car. Using the air conditioner for a long time will make the condenser pressure too high, which will cause losses to the refrigeration system. Therefore, the time of using the air conditioner should not be too long. If the temperature in the car has reached a comfortable temperature, you can turn off the air conditioner and turn it on again after a while.

The second mistake is to clean the air conditioner when its performance is poor
Some novices always have to wait until the air conditioning effect is bad before they think of cleaning the air conditioning, which is wrong.
The technical maintenance personnel pointed out that the air conditioner filter should be replaced regularly, because there are many dust and willow catkins flying in Beijing in spring, which will be stained on the filter, easy to grow bacteria and make the air conditioner produce a musty smell, so it is best to replace it once every spring. In addition, the condenser should also be cleaned regularly, and the water tank should be removed for complete cleaning.

The third mistake is that the direction of the air outlet of the air conditioner can be adjusted at will
Some car owners do not pay attention to adjusting the direction of the air conditioner when using the air conditioner, which is not conducive to the best effect of the air conditioner. According to the principle of cold air sinking and hot air rising, the correct way is to turn the air outlet up when turning on the cold air and down when turning on the heating.

The fourth mistake is that the air conditioner is not turned on all winter
Winter in some areas is relatively warm, and some car owners do not use air conditioning all winter. If the air conditioner is not used for a long time, its rubber ring will be aged, and the lubricating oil on the components inside the air conditioner will also become dry. Regularly starting the air conditioner can make the components receive lubricating oil and maintain good condition. Therefore, it is better to start the air conditioner once a week in winter.

The fifth mistake is to start the internal circulation immediately after entering the vehicle in summer
In the hot summer, many car owners are used to turning on the internal circulation of the air conditioner as soon as they enter the car, thinking that this can make the temperature in the car drop faster. Because the temperature inside the car is higher than that outside the car, this is not good. When you first enter the car, you should open the window for ventilation and open the external circulation to exhaust the hot air. After the temperature in the compartment drops, it can be replaced with internal circulation.

The sixth mistake is to open internal circulation for a long time
Because the internal circulation is the circulation of air in the enclosed space of the vehicle, the oxygen content in the vehicle will continue to decline, and if the gasoline in the cylinder is not completely burned, the unburned carbon monoxide of the engine may also leak into the compartment, so the air quality in the vehicle will become worse and worse, even causing harm to the human body. Therefore, we should turn on the internal circulation for a while and the external circulation for a while to let fresh air enter the carriage. It is the same reason that you cannot sleep in the car with the internal circulation.

The seventh mistake is to turn off the engine before turning off the air conditioner
Some car owners often turn off the air conditioner only after the engine is turned off, which is harmful to the engine, because the engine will start with the load of the air conditioner the next time the vehicle starts, and such high load will damage the engine. Therefore, the air conditioner should be turned off and then off after each stop, and it should also be turned on after the vehicle is started for two or three minutes and the engine is lubricated.

The eighth mistake is never to use large air volume
Some car owners don't like the noise when the air conditioner is turned to high gear, so they seldom or never turn the air conditioner to high air volume. When the air conditioner is used, it will suck in a lot of dust. Regular high wind can blow out the floating dust on the inner surface of the air duct of the air conditioner. This is a simple way to keep the air conditioner clean. In addition, special duct cleaning fluid shall also be used for sterilization, cleaning and odor removal.
