1 one 启动汽车后立刻打开空调 Turn on the air conditioner immediately after starting the car 汽车长时间在烈日下曝晒，狭小而封闭的车厢会导致车内的空气流动性较差，在持续被烈日长时间“烘烤”之后，车厢内的温度要远远高于室外温度。如果此时打开车门，瞬间就会有一股热浪袭面而来······很多人在遇到这种情况时，都会立刻启动汽车，打开空调，并且将风速调到最大，以达到最快的制冷效果。其实这样做不光不能快速降低车内温度，还会在一定程度上损耗发动机。 Car for a long time in the hot sun exposure, narrow and closed carriage can lead to poor air flow inside the car and continues to be a sun in the "bake" for a long time, the temperature of the car is far higher than the outdoor temperature. If at this time, open the door, there will be a moment a heat wave surface to · · · · · · a lot of people in this situation, will immediately start the car, open air conditioning, and switch to a maximum wind speed, in order to achieve the fastest refrigeration effect. In fact, it can not only reduce the temperature of the car quickly, but also reduce the engine to a certain extent. 通常来说，汽车在启动之后，转速表指针往往会一下子爬升到较高的转速，几秒钟之后再下降到一个相对稳定的转速。如果在刚刚启动的时候就打开空调压缩机，会增加发动机运转的负荷，长时间如此会损害发动机。所以正确的做法应该是先将四个车窗打开，使空气对流通风，让车厢内的温度尽快与室外温度持平。待发动机转速平稳，再将车窗关闭，打开空调，这样既不损害发动机，又能很快降低车内温度。 Usually, when the car is started, the tachometer pointer tends to climb to a higher speed and then drop to a relatively stable speed a few seconds later. If you turn on the air conditioning compressor at the beginning, it will increase the load on the engine, which will damage the engine for a long time. So the right thing to do is to open the four Windows first, to air convection, and to keep the temperature inside the car as fast as it is outside. The motor speed is stable, and the car window is closed to turn on the air conditioner, which will not damage the engine, but can quickly reduce the temperature in the car. 2 2 长时间使用空调内循环 Use air conditioning cycle for a long time 很多人在夏天开空调时，害怕车外热气进入车内影响制冷效果，就会一直开启内循环模式。其实这样做不对，长时间使用内循环模式会造成车厢内的含氧量降低，而且如果汽缸中的汽油燃烧不完全，发动机未燃烧尽的一氧化碳也有可能漏进车厢内。 Many people in the summer when the air conditioning, fear that the heat outside the car will affect the refrigeration effect, will always open the inner circulation pattern. Really do wrong, the long time use inner loop mode will cause the car of the oxygen content is reduced, and if the cylinder incomplete combustion of gasoline engine without combustion of carbon monoxide is also likely to leak into the car. 此时内循环模式会使车厢处于一个几乎封闭的状态，车内的空气质量会越来越差，严重时会对人体会产生危害。所以夏天开空调时，切忌长时间使用内循环模式。正确的做法是采用内/外循环切换的模式。可以在开一段时间内循环之后再切换到外循环模式，以此来给车厢内更换点新鲜空气 In this case, the inner circulation mode will put the car in an almost closed state, and the air quality in the car will become worse and worse. Therefore, when it comes to the summer, you should avoid using the inner circulation pattern for long periods of time. The correct approach is to use the internal/external loop switching mode. You can then switch to the outer loop mode after a period of time to change the fresh air inside the car
