小枫汽车养护DIY,每天分享最新最有趣的故事!
昨天有人联系小枫~说她的车开着空调还是像个大烤箱!这不是第一个粉丝这样问我了,今天我就来给大家分析一下,汽车空调到了夏季怎样用才会让你凉爽惬意
首先,我们先了解一下汽车空调的制冷系统组成吧,汽车空调制冷系统主要由干燥瓶、蒸发器、散热风扇、膨胀阀、压缩机、冷凝器、氟利昂、鼓风机和管路以及电子控制部件组成
当驾驶员开启空调压缩机(ac)时,压缩机开始工作,这时压缩机接入从蒸发器出来的低温压的气态制冷剂,经过压缩机压缩,制冷剂的温度和压力升高,被送入冷凝器,冷凝器时位于车辆前方的热交换器,在冷凝器中,制冷剂释放热量,并转换成液体的形式。有时冲压空气不足以使用额外的发动机或电动风扇来冷却制冷剂,这种冷却但高压的制冷剂允许通过脱水器提取任何水分,使干燥的制冷剂通过膨胀阀允许制冷剂膨胀至低压,从而冷却蒸发器,来自鼓风机的空气流过蒸发器盘管后产生冷气。
原理我们大家了解以后,就来说一说在使用前应注意哪些事项。有些车主在冬季和春季不会使用汽车空调,那么在夏季使用之前,对空调系统的检查时很有必要的。在使用空调之前,对空调的管道通风系统清洗,会有效的驱除霉味和土味,可以有效地抑制细菌的生长,同时汽车的空调滤芯,也应及时检查,如需更换,则要换新的(空滤价格很便宜)这样夏天开空调,就可以保证车内空气的新鲜。同时也应检查制冷剂的容量,如容量较低应及时添加
那么应该怎样使用汽车空调呢?
一、利用好汽车的内外循环
在刚刚启动汽车空调时,空气循环应选择外循环,降低车内温度,待车内温度降下来时,在切换回内循环,这样可以时汽车迅速降温也可使车厢内的浑浊气体排出。这时切换为空调内循环,会因制冷效率全部回收而节省能源,这样做既省油,又能早早享受空调带来的凉意
二、不要在怠速下长时间开空调
这样发动机非常容易产生积炭,对发动机的动力系统、散热系统、蓄电池和整个空调都产生不良的影响,增加了汽车的故障率减少了使用寿命
三、禁止开空调在车内睡觉
由于汽车密封性较好,睡觉后会产生大量的二氧化碳,严重可导致窒息,所以最好不要在车内睡觉,如特殊情况,应打开一半车窗保障车内氧气充足,开空调在车内睡觉更为严重,严禁在在密封的汽车内开空调睡觉。
以上几点你学会了嘛?汽车空调学问大,小技巧却很简单,学会了就赶紧分享给朋友们吧
