1. choose the right air conditioning temperature. Of course, in the summer, many people like to keep the temperature very low. As everyone knows, when the temperature is too low, it will affect the health of the body, so the air conditioning temperature adjustment must be appropriate. The most suitable temperature for human body is 20℃ to 25℃, more than 28℃, people will feel stuffy. Below 14℃, people will feel cold. Therefore, the air conditioning should control the temperature in the car between 18℃ and 25℃, the temperature is too low to make people sick.
2. Start the inner cycle immediately after getting into the car in summer. When the car is parked in the hot sun for a long time, some owners like to turn on the air conditioning and turn on the inner cycle as soon as they start the car, thinking that this can make the temperature inside the car drop faster. But because the temperature inside the car is higher than the temperature outside the car, so this is not effective. When you just enter the car, you should first open the window for ventilation, and open the external circulation to exhaust the hot air. When the temperature inside the car drops, switch to internal circulation.
3. people know to use air conditioning in a fully closed state. For the car air conditioning is the same, in the process of use if the door, the window closed loosely, will make the refrigeration effect is not good, but also waste fuel.
4. air outlet direction at will. Some owners in the use of air conditioning, do not pay attention to adjust the direction of air conditioning, which is not conducive to the best effect of air conditioning. According to the principle of cold air sinking and hot air rising, the correct approach should be to turn the air outlet up when the cold air is turned on, and turn the air outlet down when the heating is turned on.
5. Leave the air conditioner on for a long time. Some owners often turn on the air conditioning after getting on the car, but using air conditioning for a long time will make the condenser pressure is too large, which will cause loss to the refrigeration system, because the air conditioning is a heavy burden on the engine, and the engine itself is a heating body, not to mention in high temperature weather. Some small displacement cars will even appear boiling water in this case, affecting driving and reducing the efficiency of air conditioning. Therefore, each use of air conditioning time should not be too long, if the temperature in the car has reached a comfortable temperature, you can turn off the air conditioning, and then open every once in a while.
6. Don't smoke in the car with the air conditioner on. Because of smoking in the carriage, the smoke can not be discharged all at once, stimulate the eyes and respiratory system, which is not conducive to health. If smoking, the air conditioning risk control system should be adjusted to the "discharge" position, so that the smoke in the carriage can be discharged out of the car.
7. Do not rest or sleep for a long time in the car with the air conditioner on. Because the car is sealed well, when the vehicle is stopped, the air permeability in the carriage is poor. If you turn on the air conditioning at this time to rest or sleep, it is likely to cause poisoning or even death due to the carbon monoxide gas discharged from the engine leaking into the car.
8. Try not to use air conditioning when driving at low speed. When driving in traffic jams, do not make the engine run at a higher speed in order to improve the efficiency of air conditioning, because doing so has an adverse effect on the service life of the engine and air conditioning compressor.
9. Turn off the fire before turning off the air conditioner. Some owners often think of turning off the air conditioning after turning off the engine, which is harmful to the engine, because when the vehicle starts next time, the engine will start with the load of the air conditioning, and such a high load will damage the engine. Therefore, after each stop, the air conditioning should be turned off and then turned off, and it should also be turned on after the vehicle starts for two or three minutes and the engine is lubricated.
