What is the car air conditioning filter
Automotive air conditioning filter is an important part of the internal air circulation system of automobiles, mainly used to filter the air entering the car to ensure the clean and comfortable air in the car. It is usually made of a high-density fibrous material that effectively traps dust, pollen, smoke, and other particles .
The role of air conditioning filter
filter dust and impurities : air conditioning filter can filter dust, pollen and other impurities in the air, prevent them from entering the car, protect the health of the car .
engine protection : for the automotive air intake filter net (also known as air intake insect-proof net or water tank protection net), its main function is to prevent mosquitoes and other small organisms from entering the intake system, to protect the engine from damage .
sterilization and deodorization : some types of air conditioning filter also has sterilization and deodorization function, can purify the bacteria in the air, to ensure the quality of air environment .
Air conditioning filter maintenance and replacement
Periodically cleaning or replacing : It is recommended to clean or replace the air conditioner air filters periodically to ensure the proper running of the air conditioner system. Long-term use may accumulate dust on the air filters, affecting the normal operation of the air conditioner .
Cleaning method : When cleaning the air conditioner air filter, unplug the power supply, open the inner panel, and clean the air filter with water or neutral detergent. Do not use excessive force to avoid deformation or damage .
The main role of automotive air conditioning filter includes the following aspects :
Filters impurities in the air : The car air conditioning filter can separate the dust, pollen, abrasive particles and other solid impurities in the air to ensure that unfiltered air will not enter the car .
adsorption of harmful substances : filter can also absorb moisture in the air, soot, ozone, odor, carbon oxide, SO2, CO2 and other harmful substances, keep the air in the car fresh, for the passengers to provide a good breathing environment .
prevent bacterial reproduction : filter can effectively filter dust, pollen and other impurities in the air, prevent bacterial reproduction, create a healthy and comfortable environment in the car, to ensure that the passenger will not affect driving safety because of allergic reactions .
Protect the air conditioning system : The air filter can prevent the unfiltered air directly into the air conditioning system, so as to protect the normal operation of the air conditioning system and extend its service life .
keep a clear line of sight : filter can prevent the car glass covered with water vapor, to ensure the clear line of sight of the passenger, to ensure driving safety .
Automotive air conditioning filter failure is mainly manifested as cooling or heating effect decline, poor air circulation, odor and other problems. Filter blockage is one of the most common causes, dust and debris will accumulate in the filter, blocking air flow, resulting in reduced efficiency of the air conditioning system .
In addition, filter damage or aging will also lead to reduced filtration effect, affecting the air quality in the car .
Fault phenomenon
Cooling or heating effect decreases : Blocked filter reduces air flow, resulting in poor cooling or heating effect.
poor air circulation : blocked filter will lead to poor air circulation, affecting the normal work of the air conditioning system.
odor : Clogged filters may breed bacteria and mold, resulting in odor.
Fault cause
filter clogged : after long-term use, dust, debris and so on accumulate in the filter network, hinder air circulation.
damaged or aging : damaged filter can not effectively filter impurities, aging filter filter effect is reduced.
solution
Cleaning or replacing air filters : To rectify faults, clean or replace air filters regularly. Dust can be blown from the back of the filter using compressed air, or clean the filter with warm water and a neutral cleaner and let dry .
Check and clean the condenser : the condenser is easily covered with dust, which affects the heat dissipation effect. Regular cleaning of dirt on the surface of the condenser can improve the cooling capacity .
Check the refrigerant : insufficient refrigerant or leakage will affect the cooling effect, you need to go to a professional maintenance shop for inspection and supplement .
Check the compressor : compressor fault will also affect the cooling effect, need to repair or replace if necessary.
