negative: 相信有不少朋友对于哈弗h6暖风怎么开启?这个问题都想了解了解,那么今天小编就给大家简单的介绍一下吧,希望可以对你有所帮助。<br>打开暖风是非常简单的,只需要将温度调高,然后选择合适的风量就行了。在使用暖风时,不需要按下ac按钮,ac按钮是汽车空调的制冷开关。<br>汽车空调是汽车上一个重要的舒适性配置,在冬季和夏季用车时几乎每天都是需要使用空调的。<br>汽车空调可以制冷也可以制热,汽车空调的制冷和制热原理是非常简单的。<br>汽车空调在制热是,发动机内的高温冷却液会流经暖风水箱,此时鼓风机吹来的风也会流经暖风水箱,这样空调出风口就可以吹出暖风了。<br>暖风水箱其实就是一个热交换器。<br>汽车空调的制冷原理也是非常简单的,在制冷时发动机会带动压缩机运行,此时压缩机可以不断压缩制冷剂并将制冷剂输送到蒸发箱内,制冷剂在蒸发箱内会膨胀吸热,这样制冷剂可以冷却蒸发箱。<br>被冷却的蒸发箱可以冷却鼓风机吹来的风,这样空调出风口就可以吹出冷风了。<br>大部分汽车空调使用的制冷剂是r134a,这种制冷剂是需要定期更换的,如果长时间不换制冷剂,会影响汽车空调的制冷效果和制冷速度。<br>如果大家要更换制冷剂,需要去专业店家,找专业人士,使用专业设备更换。
