In the cold winter, the temperature inside a car without air conditioning is comparable to a small ice cave. When the car door is opened, the cold wind is howling. At this time, car air conditioning is very important. A well maintained car air conditioning can raise the temperature to a comfortable temperature for the human body in just three or four minutes. Proper maintenance of car air conditioning can not only improve the service life of the air conditioning system, but also maintain its good working condition. Therefore, the maintenance and upkeep of the air conditioning system has become a concern for many car owners. So, how to maintain car air conditioning in winter?
1. Disassemble and clean car air conditioning
(1) Air conditioning filter cleaning/replacement
Under normal circumstances, the service life of an original air conditioning filter is one year or 30000 kilometers. If the air conditioning filter is regularly cleaned, it can not only ensure fresh air in the car but also extend the service life of the air conditioning filter.
The first step in cleaning the air conditioning filter is to locate the air conditioning filter element. Because the position of the filter is different for each model, some car air filters are placed under the front windshield of the car, while others are placed in the glove box of the passenger seat. Owners can check the vehicle manual or consult the car 4S store.
The disassembly methods for different brands of vehicle models may vary slightly, but it won't be too difficult. If not, you can check the vehicle manual.
After using the air filter for a period of time, it usually accumulates a lot of dust and dirt. If it is too dirty, throw it away. If the air filter is not very dirty, the car owner can use a hair dryer to blow the air conditioning filter from inside out clean. At the same time, be sure to install the arrow indicator during installation, otherwise the air conditioning filter will not only fail to function, but also blow dust into the car.
(2) Air conditioning pipeline cleaning
The cleaning of air conditioning pipes requires the purchase of air conditioning cleaning agents, which can be purchased by car owners online or at auto parts stores. The price is generally around 30 yuan.
Before formal cleaning, shake the air conditioning cleaning agent well and cover the hose inside the packaging. Then, turn the air conditioning volume to maximum and adjust it to the external circulation mode. But do not turn on the air conditioning compressor (the A/C button is in the off state).
Spray the shaken cleaning agent onto the position of the air conditioning filter element for spraying, and the suction inside will suck in the cleaning agent to clean the air conditioning pipeline. It is particularly important to note that the hose above the cleaning agent should not be too close to the blower to avoid being stirred in. After spraying the cleaning agent, the car owner can let the air conditioning system run in external circulation mode for another 10 minutes. After the engine is turned off, the cleaning agent will defoaming and become liquid flowing out of the vehicle through the drainage outlet after cleaning the evaporator and air duct.
(3) Evaporation tank cleaning
Evaporation box cleaning mainly involves cleaning the evaporator, which is filled with refrigerant. If there is dirt stuck inside the evaporator, can the car air conditioning not smell? Cleaning the evaporator is also very simple, just rinse it with water.
