汽车空调如何正确使用内外循环。在驾驶中不正确的使用内外循环系统只能是适得其反,通过本篇希望能帮到大家正确使用内外循环系统。汽车在不开空调开窗的情况下,打开外循环,让外风进入车里,使外面的温度接近车里室内的温度。开着空调的情况就要把外循环关了启动内循环,假如你开着空调,外循环一直开着,车里的温度很难达到空调设定的温度值,外界的热空气一直往里面进。夏天汽车在露天暴晒时,会引起车内温度升高,很多人都是上车前开空调降温后再开车,急用的就直接上车把空调温度调最低风力最大,正确的使用是上车了把车窗摇下来让外风进入车内,使车内很快的降到车外的温度后再开空调。冬天使用汽车时,车窗总是起雾,让人很恼火,大多数人都是开冷气吹着玻璃除雾,方法是车窗起雾是内外的温差大,开车时,窗户不要全关,打开外循环,这样除雾的空气温度接近车外温度除雾效果显著。
今天要给大家分享的案例跟车辆的内外循环有关。近日进店一辆老款皇冠轿车
车主进店做小保养顺便检查一下空调,车主描述车子的空调一到中午就不凉了,维修师傅接到车辆先做个小保养,做完保养后对车辆空调系统进行检测,
拿来专用压力表对高低压进行检测发现压力正常,维修师傅检测内外风循环情况以及空调出风量,维修师傅拿来温度计检测外循环时空调温度和内循环时空调温度,检测后发现温度几乎没有变化,温度不变化显然是不对的,正常怠速时外循环要比怠速时内循环空调温度高5度以上(外循环吸入外界热的空气)维修技师检测内外循环翻板是否卡滞,维修师傅用内窥镜从风道缝隙看内外翻板操作内外循环发现翻板不动一直外循环,难道是翻板电机卡在外循环处,维修技师拆出鼓风机拆出内外翻板及风道
一下子明白了,翻板电机好好地就是连接翻板的轴断了,这下可能要换掉一个风口,维修师傅与车主沟通后车主表示不换了你给我用胶水粘一下能用就好
于是维修师傅拿来胶水把断掉的轴粘好,装好所拆下的东西
更换新的空调芯,打开空调测试温度检测外循环温度再检测额内循环温度,再怠速情况温度相差8度多故障排除(外循环吸入发动机舱的热空气)维修师傅跟车主讲明白内外循环后,车主把车子开走。
你们对这个如何看,在下面留言大家一起评
