In summer, the air conditioner must be essential for travel. The air conditioner in the car must be specially maintained in order to play its greatest role when needed. How should the air conditioner in the car be maintained in summer? Now let's learn
How to maintain the car air conditioner
1、 Be careful when refitting the air conditioner
It is not recommended to refit the car's air conditioner, because the original air conditioner is matched with the car's engine. If refitted at will, it will affect the performance of the car.
2、 The air conditioning temperature should not be too low
Selecting the appropriate air conditioning temperature is the first step of air conditioning maintenance. Due to the hot weather, many car owners like to adjust the temperature too low, which will affect their health. Under normal conditions, the difference between the temperature in the compartment and the outside temperature shall be 5 ℃ to 6 ℃, that is, the optimal temperature of the air conditioner is 18 ℃ to 25 ℃.
3、 Control air outlet direction
We who think we have rich knowledge of physics must remember the principle of cold air sinking and hot air rising. Don't forget to learn and use it flexibly. Principle of air outlet of automobile air conditioner: when the air conditioner is turned on, the air outlet shall be upward, and when the heating is turned on, the air outlet shall be downward.
4、 Don't open it too long
We know you are 'not bad for money', but we still encourage you to turn off the air conditioner properly during driving. Using the air conditioner for a long time will cause excessive pressure in the condenser, which will cause loss to the refrigeration system. Therefore, if the temperature in the car has made you happy, you might as well turn off the air conditioner for a while and let it rest for a while.
5、 Open the large air volume properly
Afraid of noise, how long have you only enjoyed the gentle wind and rain in the small wind? Let it sing a song appropriately! When the air conditioner is used, it will absorb a lot of dust. Regular high winds can blow out the floating dust on the inner surface of the air duct. The simplest method is the most effective.
6、 Turn off the air conditioner when driving at low speed
When driving at low speed, try to turn off the air conditioner. In case of traffic jam, do not make the engine run at a higher speed in order to improve the air conditioning efficiency, which will shorten the service life of the engine and air conditioning compressor.
7、 The switching procedure should be kept in mind
Turn off the air conditioner first and then turn off the engine, which can ensure that the vehicle is simply started at the next start; On the contrary, the air conditioner that is not completely turned off will start with the engine, so high load operation will damage the engine. Many car owners often think of turning off the air conditioner after turning off the engine. Therefore, turn off the air conditioner and then turn off the engine after each stop. It is best to turn on the air conditioner after the vehicle is started for two or three minutes and the engine is lubricated.
8、 Air conditioning for a long time in the hot sun
For vehicles parked in the hot sun for a long time, the temperature in the compartment is very high. In this case, do not use the air conditioner immediately after the vehicle is started. First open all the windows for ventilation and exhaust the hot air. After the temperature in the compartment drops, close the windows and turn on the air conditioner. In addition, the air conditioner shall not be turned on and off frequently to prevent damage to the air conditioning system. Especially for pickup truck models, it should be avoided to switch on and off the air conditioner repeatedly when shipping goods in a short time.
9、 Turn on the air conditioner in the car and try not to smoke
When the air conditioner is turned on in the car, passengers shall not smoke in the car. If you smoke, please adjust the ventilation control of the air conditioner to the external circulation position. It should also be noted that you should remember not to rest or sleep for a long time in a parked car with air conditioning on. When the vehicle stops, the ventilation in the closed compartment with air conditioner on is poor. If the air conditioner is on to rest or sleep at this time, it is likely that the harmful gas discharged by the engine will leak into the vehicle, causing personnel poisoning and even life-threatening.
Why is the car air conditioner maintained
As one; Circulate refrigerant oil, clean pipes and enhance refrigerant effect. Such as II; Complete maintenance of indoor disinfection, sterilization and deodorization. For example; A quick maintenance is recommended for the 2011 model year car, and a routine maintenance is required for the 07 model year car. In addition, more than 10-year-old models require in-depth maintenance. The maintenance prices of various air conditioners are the same, but the maintenance time is different. The rapid maintenance lasts for 60 minutes, the conventional maintenance lasts for 70 minutes, and the in-depth maintenance lasts for 80 minutes. After this maintenance, the refrigeration effect is greatly improved, the air is obviously refreshed, and the compressor lubrication system is good, which can also reduce fuel consumption.
What's the harm of not maintaining the car air conditioner
(1) A large amount of backhaul and dirt accumulated on the surfaces of filters, radiators, evaporators and fins, resulting in airflow blockage.
(2) , resulting in decreased refrigeration and heating effects and increased power consumption and noise.
(3) Reduce the service life of air conditioner; (4) Produce peculiar smell, breed bacteria and mites, and endanger people's health.
