The following conditions prove that the air conditioning filter needs to be replaced
Air conditioning is a great invention of human beings, with the continuous improvement of people's living standards, air conditioning has gradually entered every household, the existence of air conditioning, but also can indeed make everyone happy to spend the hot summer. And now air conditioning is not only indispensable in the home, but also in the car.
But whether it is a household air conditioner or a car air conditioner, regularly cleaning and replacing the air conditioning filter element can not only keep the refrigeration effect in a good state, but also make the air conditioner blown out by the air conditioner more refreshing and healthier.
The service life of the car air conditioning filter element has a great relationship with the car environment, and long-term driving on the dusty road will greatly reduce its life. So in the process of using the car, what are the situations that prove that the air conditioning filter element is dirty and needs to be replaced? Let's learn it with you.
1. There is a peculiar smell
The main function of the air conditioner filter is to filter the air into the car, when the air quality outside is relatively poor, there will be dust or odorous substances with the air into the car, sticking to the surface of the air conditioning filter.
Especially on rainy days, the air contains a lot of moisture, and the air conditioning filter element is very susceptible to moisture and mildew, thereby breeding bacteria and producing peculiar smells. Therefore, if it is found that there is a peculiar smell when turning on the air conditioner, the air conditioning filter element is the first factor to consider.
2. The cooling effect of air conditioning is poor
The cooling effect of the air conditioner is not ideal, there are many possible factors, insufficient refrigerant, poor heat dissipation, and damage to the air conditioner pump, which may lead to poor or no cooling of the air conditioner.
The air conditioning filter element is dirty and blocked, and the ventilation is poor, which will also cause poor air conditioning cooling. If you feel that the vehicle air conditioner is not cool enough, and the air output is small, you can consider the problem of the air conditioning filter.
3. Switch the external circulation, the air volume is very small
This situation is the same as the second point, the air conditioning filter is too dirty and clogged causing poor air circulation, and it feels like there is no wind.
However, this situation is only for some models, when the air conditioner of this type is in the internal circulation, the air is not filtered by the air conditioning filter, and once it is switched to the external circulation, the air is filtered by the air conditioning filter, and the air volume is small, which can be considered that the air conditioning filter is dirty.
Of course, there are some models of internal and external circulation of air is through the air conditioning filter, under normal circumstances, the air conditioning filter element is located in the car, internal and external circulation mode, the air is filtered by the filter element, and the air conditioning filter element is located outside the car, only in the external circulation, the air is filtered by the air conditioning filter.
The above is a simple way to judge the status of the air conditioning filter element in the process of daily car use. Code words are not easy, click to follow, share car knowledge every day! #Cars# #汽车知识#
