First, choose the right air-conditioning temperature. Of course, in summer, many people like to keep the temperature low. As everyone knows when the temperature is too low, will affect the health of the air conditioning temperature adjustment must be appropriate. The most appropriate body temperature is 20 ℃ to 25 ℃, more than 28 ℃, people will feel hot. And below 14 ℃, people will feel cold. Therefore, the air conditioner should control the car temperature between 18 ℃ to 25 ℃, the temperature is too low can make people sick.

Second, the summer into the car immediately start the inner loop. When cars parked in the sun for a long time, some owners like to turn on the air-conditioner immediately and turn on the inner loop as soon as they start the car, believing that this will allow the cabin temperature to drop faster. But because the temperature inside the car is higher than the temperature outside the car, so the effect is not good. Just enter the car, it should first open the window ventilation, and open the outer loop, the heat are discharged. Wait for the temperature inside the car to fall, then change into the inner loop.

Third, people all know to use the air conditioners in the completely closed state. The same is true for the car air-conditioning, if the use of the car doors, windows closed lax, will make the cooling effect is poor, but also a waste of fuel.

Fourth, the direction of the air conditioning outlet tone. Some owners in the use of air conditioning, do not pay attention to adjust the direction of air conditioning hair, which is not conducive to the best use of air conditioning. According to the sinking of cold air, the principle of hot air rising, the correct approach should be, open the air outlet will be up, open the air outlet will be down when heated.

Fifth, long time with air conditioning. Some car owners often drive air conditioners after getting on the bus, but prolonged use of air conditioners can cause the condenser to overpressure, which can cause losses to the cooling system because air conditioning is a heavy burden on the engine and the engine itself is a heat Body, not to mention under hot weather. Some small-displacement cars in this case may even appear water boiling phenomenon, affecting driving also reduces air conditioning efficiency. Therefore, each use of air conditioning time should not be too long, if the car temperature has reached a comfortable temperature, you can turn off the air conditioning, and then open again.

Six, do not smoke in the car with air conditioning. As smoking inside the car, the smoke can not be discharged at once excite the eyes and respiratory system, is not conducive to health, if smoking, air conditioning and ventilation control should be adjusted to the "discharge" position so that the cabin exhaust smoke.

Seven, not in the open air-conditioned car for a long time to rest or sleep. Due to the good sealing of the car, when the vehicle is stopped, the ventilation in the carriage is poor. If the air conditioner is resting or sleeping at this time, it is very likely that the CO gas discharged from the engine will leak into the car and cause poisoning and even death.

Eight, try not to use air conditioning when driving at low speed. In traffic jams, do not run the engine at higher speeds to improve air conditioning performance, as doing so adversely affects the life of the engine and air conditioning compressors.

Nine, turn off the air before turning off the air conditioning. Some owners often think of turning off the air conditioner after turning it off, which is detrimental to the engine because when the vehicle starts next time, the engine starts with a load of the air conditioner, which can damage the engine. Therefore, after each shutdown should turn off the air conditioning and then turn off, but also should start two or three minutes in the vehicle, the engine is lubricated, and then turn on the air conditioning.
