In very cool weather, why do many luxury cars have to close the windows and turn on the air conditioner?
Although there have been heavy rains recently, the city where the servant is located has obviously entered a hot summer. When driving on a hot day, the first thing you do after entering the car is to turn on the air conditioner. But how to use car air conditioners correctly so that we can feel cool and save money? Let me introduce to you some tips on using air conditioners~
1. Ventilate and cool down first before turning on the air conditioner
If you enter a car that has just been exposed to the sun, do not turn on the air conditioner in a hurry. When we open the car door, we usually feel a wave of heat hitting us. This is because in the relatively closed environment inside the car, the lack of air circulation leads to heat accumulation. You must wait until the body temperature drops before turning on the air conditioner. Because in this way, not only can the harmful things in the car be discharged as much as possible, but it can also make the cooling effect better and cooler!
At this time, you can open a car door and push and pull it hard several times (like a fan), or you can quickly extract the hot air from the car. Wait for the temperature inside the car to drop before starting the engine and turning on the air conditioner. This will save fuel! At the same time, you can also lower three windows first and leave one closed. In this way, after the air enters the car, it will gather in large quantities in the rear row to form a high-pressure area, forcing the hot air in the car to be discharged out of the rear window.
2. Don’t always turn the air conditioner on low gear
In summer, when we drive on the road, the air conditioner cannot always be turned on low gear, because if the air conditioning system is kept in low gear for a long time, a lot of dirt will be produced. , and even cause mildew. If people inhale it into the body, it will have a great impact on the body, so the low setting should be as high as possible during meetings!
At the same time, in terms of air conditioning air volume, although the air volume has nothing to do with fuel consumption (air conditioning refrigeration and air outlet belong to two systems, the air volume is achieved by changing the speed of the blower, which does not affect fuel consumption), but This does not mean that it is correct to turn on the highest gear all the time. Excessive craving for coolness may cause migraines. After the temperature inside the car stabilizes, you can appropriately adjust the air volume of the air conditioner to reduce the noise in the car and avoid physical discomfort.
3. The direction of the air outlet of the air conditioner is upward
Theoretically, the principle of air convection is that hot air rises and cold air falls. Therefore, we should blow the air outlet of the air conditioner upward. When the cold air drops, the temperature inside the car can be dropped more quickly. When the temperature inside the car reaches the set value, it can also reduce some fuel consumption. As a special reminder, everyone needs to be careful not to place any decorations in front of the air outlet of the air conditioner. This will block the air flow from the air outlet and directly affect the cooling effect of the air conditioner.
4. Turn off the air conditioner before turning off the engine
If we reach the destination and stop the engine, we must turn off the air conditioner first and then turn off the engine; because if the engine is turned off directly, the impact on the engine will be very serious. Large, and after starting again, the starting load of the engine will also increase, which will also consume more fuel, so be sure to remember this, as it will definitely cause problems over time!
5. Do not turn on the air conditioner and close the car doors and windows for a long rest.
When summer comes, many car owners like to turn on the air conditioner and close the windows to take a rest. This is completely wrong! Because the engine will idle for a long time when the air conditioner is running, the engine will produce harmful substances such as carbon monoxide during the idling process. Once a person in a coma inhales it for a long time, it will cause chest tightness and even suffocation! Therefore, when you turn on the air conditioner during rest, you can open a small window or open the skylight to a certain angle.
