一、汽车降温技巧
1、 Car cooling techniques
1.抡车门
1. Swing the car door
只开副驾车窗，反复开关驾驶室车门5次。只需要滑下副驾门玻璃，然后匀速开关左前门5次。
Only open the passenger window and repeatedly open and close the cab door 5 times. Just slide down the front passenger door glass and open and close the left front door 5 times at a constant speed.
2.空调+开窗
2. Air conditioning+window opening
打开空调，调到挡(4挡)，开启外循环。同时打开所有车窗和天窗。1分钟左右关闭所有车窗与天窗，将外循环改为内循环，同时将空调风量降到一半
Turn on the air conditioning, shift to gear (4th gear), and start the external circulation. Open all windows and sunroof simultaneously. Close all windows and sunroof in about 1 minute, change the external circulation to internal circulation, and reduce the air conditioning volume to half
3.液体降温
3. Liquid cooling
以水、酒精10:1的比例调溶液，打开车门后，摇下车窗，在车内喷洒溶液。
Mix the solution in a 10:1 ratio of water and alcohol, open the car door, roll down the car window, and spray the solution inside the car.
酒精的浓度不要过高，喷洒量不必太大，不然会有隐患。同时打开车窗，开冷气时将出风口向上，因为冷空气重于热空气，会自动下沉。而且酒精极易挥发，学过初中物理的同学应该都知道挥发是吸热的。
The concentration of alcohol should not be too high, and the spraying amount should not be too large, otherwise there may be safety hazards. At the same time, open the car window and turn on the air conditioner. Turn the air outlet upwards because cold air is heavier than hot air and will automatically sink. Moreover, alcohol is highly volatile, and students who have studied middle school physics should know that volatilization is endothermic.
二、夏季汽车降温技巧
2、 Summer Car Cooling Tips
1、先把热气排出去
1. First, exhaust the hot air
在夏天太阳直晒的情况下，车内的温度有可能高40多摄氏度甚50摄氏度。如果打开车门就一屁股坐上去，那感觉跟铁板烧没什么区别了。这时就算你马上打开空调并调风、的温度，你也会发现温度一时半会还降不下来。
In direct sunlight during summer, the temperature inside the car may reach over 40 degrees Celsius or even 50 degrees Celsius. If you open the car door and sit on it, it feels no different from burning iron plates. Even if you immediately turn on the air conditioning and adjust it to the lowest temperature, you will find that the temperature will not drop for a while.
所以，更舒服的办法是，先别上车，而是想办法把热气排出去。其实做法很简单，把空调出风打开，然后打开另一边车窗，用一边车门来不断地扇，就像扇扇子一样。利用空气流动的原理，通过这样的动作，就能很快地把热气排出，这时再开空调制冷就事半功倍了。
So, a more comfortable way is not to get on the car yet, but to find a way to exhaust the hot air. The method is actually very simple. First, turn on the air conditioning outlet, then open the other side of the car window and use one side of the car door to continuously fan, just like a fan. By utilizing the principle of air flow, hot air can be quickly discharged through such actions, and turning on the air conditioner for cooling is twice as efficient as half the effort.
2、记得打开内循环
2. Remember to open the inner loop
一些车主的空调一直都是保持外循环状态，其实如果论制冷效果的话，还是内循环状态下快实现冷效。当你打开内循环时，你会发现空调的出风也会大一些。
Some car owners always keep their air conditioning in an external circulation state. In fact, when it comes to cooling efficiency, it is still the fastest to achieve cooling efficiency in an internal circulation state. When you turn on the internal circulation, you will find that the air conditioning output will also be higher.
3、出风口朝上
3. Air outlet facing upwards
原来，空调的出风口朝向也有讲究!，因为冷空气会向下沉，因此把风向调向上吹，效果会;另外不要把风口吹向挡风玻璃，除了容易出现雾气之外，更因为玻璃的温度很高，会把大部分制冷效果都抵消掉哦。
Originally, the orientation of the air conditioning vents is also important! Firstly, because cold air tends to sink, adjusting the direction of the wind to blow upwards can have an effect; Also, do not blow the air vent towards the windshield, as it is prone to fogging and the high temperature of the glass can cancel out most of the cooling effect.
