When the vehicle starts/stalls, the timing of the air conditioner
These are two details that are very easy to ignore, many cardholders will turn on the cooling of the air conditioner for a long time in the summer, and the damage to the vehicle is still relatively serious.
First of all, let's talk about the starting state, the air conditioning compressor will increase the load of the electrical system, and the load of the starter will inevitably increase when starting, and long-term starting with air conditioning will affect the life of the starter, especially for low-end models. Some high-end models have automatic air conditioners with protection functions that allow the compressor to work only after the vehicle is started.
Let's talk about the flame-out state, the air conditioner will accumulate a lot of moisture inside when refrigerating, and these waters can only be accumulated inside the air conditioner after the direct flameout, and it will definitely be moldy and breed bacteria for a long time, and many card friends should have smelled the sour smell from this.
Therefore, the correct way to use it is to turn on the air conditioner every time the vehicle starts, and turn off the air conditioning compressor 2-3 minutes in advance before the vehicle turns off.
The air outlet blows upwards for cooling
Adjusting the direction of the air outlet at will will affect the cooling efficiency of the air conditioner, according to the principle of cold air sinking and hot air rising, the air outlet can be adjusted upward in the cooling state to exert the best cooling effect.
It is also not good to adjust the temperature of the air conditioner to the lowest for a long time
Even if the heat is difficult, it is best not to adjust the air conditioner to the lowest temperature for a long time, the huge temperature difference between the inside and outside of the car is easy to cause colds and even air conditioning diseases, if it is an automatic constant temperature air conditioner, 26 ° is a more suitable temperature.
To check diligently
First of all, check the air conditioning filter element and air duct frequently. There is a lot of sand and dust on the road, which is easy to adsorb on the filter element, causing blockage and breeding bacteria, and the air duct is also easy to accumulate dust, often causing the air volume of the air conditioner to become smaller, producing moldy odor. Therefore, it is best to replace the air conditioning filter once a summer.
Secondly, it is best to use a high-pressure water gun to clean the condenser located at the front of the car every time the car is washed to prevent the heat dissipation leaves from being blocked by insects, leaves and other debris, which affects the heat dissipation effect. Regularly check the tightness of the belt of the air conditioning compressor, the belt is too loose will cause slippage, so that the compressor can not work normally, too tight will aggravate excessive wear of the belt and break.
Good refrigerant
The most common faults in vehicle air conditioning systems are refrigerant leakage and poor refrigeration, and the cause of refrigerant leakage is usually caused by aging seals in pipelines and damage to system components. Therefore, in the maintenance process must ensure the quality of refrigerant and refrigeration oil, if inferior refrigerant is used, it will lead to abnormal compressors, poor refrigeration, pipeline corrosion and explosion, damage to important components, etc. In case of poor refrigeration, professional inspection and maintenance are required.
