It's getting hotter and hotter. When you stop, do you turn off the fire first or turn off the air conditioner first? Many car owners often think of turning off the air-conditioning after the fire goes out. In fact, this practice is very harmful!

　　錯(cuò)誤做法：先熄火再關(guān)空調(diào)

　　Wrong Practice: Turn off the fire first and then turn off the air conditioner

　　先熄火再關(guān)閉空調(diào)對(duì)發(fā)動(dòng)機(jī)是有害的，因?yàn)檫@樣在車(chē)輛下次啟動(dòng)時(shí)，發(fā)動(dòng)機(jī)會(huì)帶著空調(diào)的負(fù)荷啟動(dòng)，這樣的高負(fù)荷會(huì)損傷發(fā)動(dòng)機(jī)。

　　It is harmful to the engine to turn off the air-conditioner first, because the engine will start with the air-conditioning load when the vehicle starts next time. Such high load will damage the engine.

　　好的做法：在到目的地之前幾分鐘關(guān)掉，這樣可以開(kāi)啟自然風(fēng)，使空調(diào)管道內(nèi)的溫度回升，消除與外界的溫差，從而保持空調(diào)系統(tǒng)的相對(duì)干燥，避免霉菌繁殖。而且也應(yīng)該在車(chē)輛啟動(dòng)兩三分鐘、發(fā)動(dòng)機(jī)得到潤(rùn)滑后，再打開(kāi)空調(diào)。

　　Best practice: Turn off a few minutes before arriving at the destination, which can turn on the natural wind, make the temperature in the air-conditioning pipeline rise again, eliminate the temperature difference with the outside world, so as to keep the air-conditioning system relatively dry and avoid mildew reproduction. Also, the air conditioner should be turned on after the vehicle starts for two or three minutes and the engine is lubricated.

　　對(duì)空調(diào)的使用方法，很多人并不是很了解，一旦操作錯(cuò)誤，不僅影響空調(diào)系統(tǒng)的性能和壽命，還會(huì)損害車(chē)內(nèi)人員的健康！

　　Many people are not very familiar with the use of air conditioning. Once the operation is wrong, it will not only affect the performance and life of the air conditioning system, but also damage the health of the people in the car.

　　1、出風(fēng)口是隨意撥動(dòng)的嗎？

　　1. Is the outlet moved at will?

　　有些司機(jī)在開(kāi)空調(diào)時(shí)，對(duì)空調(diào)吹的風(fēng)向并不注意調(diào)整，從而影響空調(diào)效果。由于熱空氣上升、冷空氣下沉的物理原理，建議駕駛員在開(kāi)冷氣時(shí)應(yīng)將出風(fēng)口適當(dāng)朝上，開(kāi)暖氣時(shí)則應(yīng)將出風(fēng)口適當(dāng)朝下。

　　Some drivers do not pay attention to adjusting the direction of air-conditioning when they turn on air-conditioning, which affects the air-conditioning effect. Because of the physical principle of hot air rising and cold air sinking, it is suggested that the air outlet should be properly upward when the driver turns on the air conditioner and downward when he turns on the heating.

　　2、空調(diào)使用時(shí)間也有考究？

　　2. How long does the air conditioner last?

　　不少司機(jī)往往都是一上車(chē)就開(kāi)著空調(diào)了，而長(zhǎng)時(shí)間使用汽車(chē)空調(diào)，就會(huì)大大增加冷凝器壓力，從而大大增加制冷系統(tǒng)損耗。所以，空調(diào)使用時(shí)間不宜太長(zhǎng)，當(dāng)車(chē)內(nèi)溫度達(dá)到比較舒適的溫度下，可適當(dāng)將空調(diào)關(guān)閉一會(huì)，過(guò)上一會(huì)再重新開(kāi)啟空調(diào)。

　　Many drivers often turn on the air conditioner when they get on the bus, and long-term use of the car air conditioner will greatly increase the pressure of the condenser, thus greatly increasing the loss of the refrigeration system. Therefore, the use of air-conditioning time should not be too long, when the car temperature reaches a more comfortable temperature, the air-conditioning can be properly shut down for a while, and then re-open the air-conditioning later.

　　3、夏季進(jìn)車(chē)立即開(kāi)內(nèi)循環(huán)？

　　3. Drive the inner cycle immediately in summer?

　　在炎熱的夏天，很多車(chē)主習(xí)慣一進(jìn)車(chē)內(nèi)就打開(kāi)空調(diào)的內(nèi)循環(huán)，認(rèn)為這樣可以讓車(chē)廂內(nèi)溫度下降得快一點(diǎn)。這樣做是錯(cuò)誤的，因?yàn)檐?chē)內(nèi)的溫度比車(chē)外溫度高，所以這樣反而效果不好。由于內(nèi)循環(huán)是空氣在車(chē)內(nèi)的循環(huán)，使車(chē)內(nèi)含氧量逐漸降低，當(dāng)氣缸中的汽油燃燒不安全，產(chǎn)生的一氧化碳、二氧化碳就可能會(huì)漏進(jìn)車(chē)廂，從而導(dǎo)致車(chē)內(nèi)空氣越來(lái)越差。因此，建議車(chē)主在使用空調(diào)時(shí)應(yīng)開(kāi)一會(huì)內(nèi)循環(huán)，再切換到外循環(huán)，以啟動(dòng)換氣的作用。

　　In hot summer, many car owners are accustomed to turn on the inner cycle of air conditioning as soon as they get into the car, thinking that this can make the temperature in the car drop faster. This is wrong, because the temperature inside the car is higher than that outside, so the effect is not good. Because the internal circulation is the circulation of air in the car, the oxygen content in the car decreases gradually. When the gasoline in the cylinder burns unsafely, the carbon monoxide and carbon dioxide produced may leak into the car, resulting in worse and worse air in the car. Therefore, it is suggested that the owner should turn on the inner cycle for a while and then switch to the outer cycle to start the ventilation.
