Do not adjust the direction of the air conditioner's air outlet at will

Some car owners do not pay attention to adjusting the direction of the air conditioner's blowing when using it, which is not conducive to achieving the best effect of the air conditioner. According to the principle that cold air sinks and hot air rises, the correct approach is to turn the air outlet upwards when using air conditioning and downwards when using heating. Car front logo

Air conditioners should be turned on regularly once in winter

In some areas, winters are relatively warm, and some car owners do not use air conditioners throughout the winter. The mechanic at the 4S store pointed out that not using the air conditioner for a long time will cause the rubber rings to age, and the lubricating oil on the internal components of the air conditioner will also dry up. Regularly starting the air conditioner can allow the components to be lubricated by the lubricating oil and maintain a good condition. Therefore, it is best to start the air conditioner once a week in winter.

It is not advisable to use the air conditioner for too long each time

Some car owners often keep the air conditioner on all the time after getting in the car. Long-term use of the air conditioner can cause excessive pressure in the condenser, which will cause wear and tear to the refrigeration system. Therefore, the air conditioner should not be used for too long each time. If the temperature inside the car has reached a comfortable level, the air conditioner can be turned off and turned on again after a while.

Before driving in summer, ventilate and cool down first, and then start the internal circulation

In the hot summer, many car owners are accustomed to turning on the internal circulation of the air conditioner as soon as they get into the car, believing that this can make the temperature inside the cabin drop faster. Because the temperature inside the car is higher than that outside, this approach actually doesn't work well. When you first get into the car, you should open the Windows for ventilation and turn on the external circulation to expel all the hot air. After the temperature inside the carriage drops, switch to the internal circulation.

It is not advisable to use the internal circulation of the air conditioner for a long time

Because the internal circulation is the circulation of air within the closed space of the vehicle, the oxygen content inside the vehicle will continuously decrease. Moreover, if the gasoline in the cylinder is not completely burned, the unburned carbon monoxide from the engine may also leak into the cabin. Therefore, the air quality inside the vehicle will become increasingly poor and may even pose a threat to human health. Therefore, the inner circulation should be turned on for a while, and then the outer circulation for a while to allow fresh air to enter the carriage. It's the same reason why you can't sleep in a car with the internal circulation on.

It is a good habit to turn off the air conditioner before turning off the engine when parking

Some car owners often remember to turn off the air conditioner only after the engine is turned off. Li Jingxiang pointed out that this is harmful to the engine because when the vehicle starts next time, the engine will start with the load of the air conditioner, and such a high load will damage the engine. Therefore, after each parking, the air conditioner should be turned off before the engine is turned off. Also, the air conditioner should be turned on only after the vehicle has been running for two or three minutes and the engine has been lubricated.
