It is another year when spring is warm and flowers are blooming. With the arrival of spring, the outdoor temperature is also fluctuating, and the use of air conditioners in cars is gradually becoming more frequent. It has been more than three years since the car was picked up at the end of 2019. In addition to regularly replacing the air conditioning filter elements, the air conditioning pipes will also be deodorized and disinfected. However, they have never been thoroughly cleaned. Today, I take advantage of the weekend to make arrangements.
As we use the car air conditioning system for a long time, a large amount of dust and dirt will accumulate on the surface of the air inlet, air duct, fan, and evaporator, which also makes it easy to breed mold in the air conditioning air duct. The turbid air produced when the air conditioner is turned on causes serious air pollution in the car, which can easily affect the health of vehicle users in such an environment for a long time. It should be emphasized that just because the air conditioner has no peculiar smell does not mean that the air conditioner does not need to be cleaned. Clean pipes will not only make the air flow smoother, but also improve the cooling and heating effects of the air conditioner, reducing the power consumption of the air conditioner, thereby reducing power consumption and fuel consumption., to a certain extent, will also extend the service life of the air conditioner.
The specific construction operation process is shared here for Toukai riders. First, find the vehicle's air conditioning filter slot, which is behind the co-driver's glove box. You can see it after removing the glove box.
Be careful not to damage the buckle when removing the glove box. For the specific process, please refer to my previous post about replacing the air conditioning filter element.
Open the front cover of the filter element slot and pull out the filter element. Because the filter element is divided into front and back sides, new drivers should pay special attention to restoring it to its original state later. The round below the slot is an air-conditioning fan.
Start the vehicle.
The car window opened.
The air conditioner turns on external circulation and adjusts the air volume to medium speed.
For the purchased air-conditioning foam cleaner, put the matching hose into the nozzle, put the other end into the filter element slot, and spray a small amount of cleaning foam intermittently towards the blower.
Through the slot, you can intuitively see that the airflow generated by the fan blows foam into the air conditioning pipes.
After the foam enters the air conditioning pipe with the airflow, it dissolves the mold stains attached to the pipe wall, and then forms a liquid that is discharged outside the vehicle through the air conditioning drain.
After spraying all the foam cleaner in, insert the air conditioning filter element and restore it to its original state.
Turn on the air conditioner AC and keep running for more than 15 minutes.
Keep the window open and wait for the air conditioning foam cleaner to effectively act on the piping. The operation is completed.
Finally, the reason why air conditioning pipes are prone to mold growth has a lot to do with the humid internal environment. In summer, riders should pay attention to leaving a few minutes to turn off the air conditioner AC before driving to their destination, adjust the internal circulation to the external circulation, adjust the air conditioner air volume to the maximum, and use as much air flow as possible to dry the moisture in the pipeline, so that mold growth can be avoided as much as possible. A healthy car-using environment also has a lot to do with our own car-using habits.
