In the hot summer, the built-in air conditioning of Shacman heavy trucks becomes an important device for drivers to maintain a comfortable driving environment. Correct use and maintenance can not only ensure the cooling effect of the air conditioning but also extend its service life and improve work efficiency.
I. Correct Use
1.Set the temperature reasonably
When using the built-in air conditioning of Shacman heavy trucks in summer, the temperature should not be set too low. It is generally recommended to be between 22 – 26 degrees Celsius. A too low temperature will not only increase fuel consumption but also may cause discomfort to the driver due to the large temperature difference after getting out of the vehicle and even trigger diseases such as colds.
For example, if the temperature is set at 18 degrees Celsius and you stay in such a low-temperature environment for a long time, your body may have a stress response and affect your health.
2.Open the windows for ventilation before turning on the air conditioning
After the vehicle is exposed to the sun, the temperature inside the vehicle is very high. At this time, you should first open the windows for ventilation to expel the hot air, and then turn on the air conditioning. This can reduce the burden on the air conditioning and achieve the cooling effect faster.
3.Avoid using the air conditioning for a long time at idle speed
Using the air conditioning for a long time at idle speed will cause poor heat dissipation of the engine, increase wear, and also increase fuel consumption and exhaust emissions. If you need to use the air conditioning in the parking state, you should start the engine at appropriate intervals to charge and cool the vehicle.
4.Alternate the use of internal and external circulation
Using the internal circulation for a long time will lead to a decrease in the air quality inside the vehicle. You should switch to the external circulation in time to introduce fresh air. However, when the air quality outside the vehicle is poor, such as passing through dusty sections, you should use the internal circulation.
II. Regular Maintenance
1.Clean the air conditioning filter element
The air conditioning filter element is an important component for filtering dust and impurities in the air. The air conditioning filter element should be inspected and cleaned regularly. Generally, it should be inspected every 1 – 2 months. If the filter element is too dirty, it should be replaced in time. Otherwise, it will affect the air output effect and air quality of the air conditioning.
For instance, when the filter element is severely blocked, the air output volume of the air conditioning will be significantly reduced, and the cooling effect will also be greatly discounted.
2.Check the air conditioning pipeline
Regularly check whether there is a leakage phenomenon in the air conditioning pipeline and whether the interface is loose. If oil stains are found on the pipeline, there may be a leakage and it needs to be repaired in time.
3.Clean the condenser
The surface of the condenser is prone to accumulate dust and debris, affecting the heat dissipation effect. You can use a water gun to rinse the surface of the condenser, but be careful that the water pressure should not be too high to avoid damaging the condenser fins.
4.Check the refrigerant
Insufficient refrigerant will lead to poor cooling effect of the air conditioning. Regularly check the amount and pressure of the refrigerant. If it is insufficient, it should be added in time.
In conclusion, correct use and regular maintenance of the built-in air conditioning of Shacman heavy trucks can provide drivers with a comfortable driving environment in the hot summer, as well as reduce the occurrence of faults and ensure the normal operation of the vehicle. Driver friends should attach importance to the use and maintenance of the air conditioning to make the journey more comfortable and safe.
