雨天行車(chē)不僅路滑，而且視線(xiàn)也不好，駕駛室內起霧是讓人討厭的，駕駛室內中控臺上的循環(huán)按鈕可以這個(gè)問(wèn)題，那么，下雨天到底是開(kāi)外循環(huán)好還是內循環(huán)好呢？很多人可能都不知道吧，今天小編就給大家介紹一下。

Driving on rainy days is not only slippery, but also has poor vision. Fog in the cab is annoying. The cycle button on the central console in the cab can solve this problem. So, in rainy days, is it better to open the external cycle or the internal cycle? Many people may not know it. Today, I will introduce it to you.

下雨天氣天冷的話(huà)自動(dòng)上料攪拌車(chē)的擋風(fēng)玻璃上全是霧，嚴重影響司機的視線(xiàn)，所以好先使用外循環(huán)風(fēng)，將風(fēng)向調整吹風(fēng)檔，開(kāi)外循環(huán)，可以把人呼出的蒸汽排出車(chē)外，而外面的冷空氣不容易凝結的。

In rainy days and cold days, the windshield of the automatic feeding mixer is full of fog, which seriously affects the driver's vision, so it is better to use the external circulation wind first, adjust the wind direction to the blowing gear, and open the external circulation, which can exhaust the steam exhaled by people outside the vehicle, while the cold air outside is not easy to condense.

一般在車(chē)窗關(guān)閉的情況下，內循環(huán)是在風(fēng)機的作用下，車(chē)內的空氣循環(huán)，由于關(guān)閉了外界空氣進(jìn)入的通道，外界的空氣進(jìn)不來(lái)，空氣比較沉悶；外循環(huán)是車(chē)內空氣循環(huán)時(shí)，循環(huán)系統打開(kāi)了外界空氣進(jìn)入的通道，有外界空氣進(jìn)來(lái)，空氣較為新鮮。

Generally, when the window is closed, the internal circulation is the air circulation in the vehicle under the action of the fan. Because the passage for outside air is closed, the outside air cannot enter, and the air is relatively dull; External circulation refers to the circulation of air inside the vehicle. The circulation system opens the passage for outside air to enter. When outside air comes in, the air is relatively fresh.

常用的辦法：剛進(jìn)入車(chē)內開(kāi)空調或熱風(fēng)時(shí)，為了使溫度迅速達到要求，開(kāi)內循環(huán)；達到溫度要求后再開(kāi)啟外循環(huán)模式，以使空氣新鮮舒適。那么什么時(shí)候開(kāi)外循環(huán)好什么時(shí)候開(kāi)內循環(huán)好呢？

Common method: When the air conditioner or hot air is turned on when entering the vehicle, in order to make the temperature meet the requirements quickly, turn on the internal circulation; After reaching the temperature requirements, open the external circulation mode to make the air fresh and comfortable. So when is it better to open the outer loop and when is it better to open the inner loop?

1.車(chē)外空氣質(zhì)量差，污染嚴重的情況下（塵土飛揚的道路、擁堵的路段行車(chē)、化工廠(chǎng)附近等有臭味或者異味的路段）用內循環(huán)可以避免外面較差空氣進(jìn)入車(chē)內。

1. When the outside air quality is poor and the pollution is serious (dusty roads, traffic on congested roads, roads near chemical plants and other roads with odor or peculiar smell), the use of internal circulation can prevent poor outside air from entering the vehicle.

2.夏天駕駛自動(dòng)上料攪拌車(chē)，為了使用空調快速降低車(chē)內溫度，可以使用內循環(huán)。

2. In summer, drive the automatic feeding mixer. In order to use the air conditioner to quickly reduce the temperature in the vehicle, internal circulation can be used.

3.自動(dòng)上料攪拌車(chē)在冬天使用內循環(huán)可以讓車(chē)內更溫暖。

3. The internal circulation of the automatic feeding mixer in winter can make the car warmer.

雨天駕駛自動(dòng)上料攪拌車(chē)可以定期的開(kāi)啟外循環(huán)，使車(chē)內進(jìn)入新鮮空氣。不管怎么樣，更重要，各位自動(dòng)上料攪拌車(chē)車(chē)友在雨天行車(chē)定要注意！更多相關(guān)內容了解就來(lái)我們網(wǎng)站http://m.jackpetty.net咨詢(xún)吧！

Driving the automatic feeding mixer in rainy days can periodically open the external circulation, so that fresh air can enter the vehicle. In any case, safety is more important. All auto charging mixer drivers must pay attention to safety when driving in rainy days! For more information, please come to our website http://m.jackpetty.net Consult!
