Summer is the season when truck air conditioning is used most frequently, and it is also the season when card users rely on air conditioning most. Meanwhile, truck air conditioning is also more prone to problems in this season. Foton car reminds you card friends, proper maintenance is especially necessary, and the use of more care is the secret of smooth operation of air conditioning.
How to use air conditioning after exposure?
After the car is exposed to the sun in summer, it must be very painful when just getting on the car. If you blindly turn down the air conditioning temperature and increase the air volume at this time, in fact, the speed of the temperature drop in the car is very slow, and you can only feel a little cool at the outlet.
Want to quickly cool the method is actually very simple, open the Windows, use the air conditioning of the external circulation blow state of the hot air in the car first exhaust, 2-3 minutes later and then close the window open refrigeration, so that the refrigeration efficiency of the air conditioning must be higher.
When the vehicle starts/turns off, the time when the air conditioning is turned on
These are two very easy to ignore details, many card friends in the summer will be air-conditioning refrigeration open for a long time, this practice for the damage of the vehicle is more serious.
First of all, the starting state of the air conditioning compressor will increase the load of the electrical system, and the load of the starter will be increased when it is started. Long-term starting with air conditioning will affect the life of the starter, especially for the middle and low-end models. Some high-end models have automatic air conditioners with protection functions, the compressor will not work until the vehicle starts.
Again, the state of extinguishing, air conditioning refrigeration internal will backlog a lot of water, directly after extinguishing the water can only backlog in the air conditioning inside, for a long time must be mildew, bacteria, a lot of card friends have smelled the sour smell should come from this.
So the correct way to use it is to turn on the air conditioner after each vehicle starts, and shut down the air conditioner compressor 2-3 minutes in advance before the vehicle turns off each time.
The air outlet blows upward for the best cooling effect
Random adjustment of the direction of the air outlet will affect the refrigeration efficiency of the air conditioner. According to the principle of cold air sinking and hot air rising, the air outlet upward in the refrigeration state can play the best refrigeration effect.
It is not good to adjust the air conditioning temperature to the lowest for a long time
Even if the heat is unbearable, it is best not to adjust the air conditioner to the lowest temperature for a long time. The huge temperature difference between inside and outside the car is easy to cause colds and even air conditioning illness. If it is an automatic constant temperature air conditioner, 26° is the most appropriate temperature.
Check diligently
First, often check the air conditioning filter and air duct. The dust on the road is more, it is easy to adsorb on the filter element, causing blockage and breeding of bacteria, and the air channel is also easy to accumulate dust, which often causes the air volume of the air conditioner to become smaller and produce mildew odor odor. Therefore, it is best to replace the air conditioning filter every summer.
Secondly, it is best to use high pressure water gun to clean the condenser located in the front of the car every time when washing, to prevent the heat dissipation blade from being blocked by insects, leaves and other debris, affecting the heat dissipation effect. Regularly check the tightness of the air conditioning compressor belt, the belt is too loose will cause skid, so that the compressor can not work normally, and too tight will aggravate excessive wear and fracture of the belt.
Good refrigerant
The most common faults of vehicle air conditioning system are refrigerant leakage and poor refrigeration. The cause of refrigerant leakage is usually caused by the aging of the seal ring in the pipeline and the damage of system components. Therefore, in the process of maintenance, we must ensure the quality of refrigerant and refrigerant oil. If inferior refrigerant is used, it will lead to abnormal compressor, poor refrigeration, pipeline corrosion and explosion, damage to important components, etc. In case of poor refrigeration, professional inspection and maintenance are required.
