判断空调是否缺冷媒或氟利昂的方法:
1、空调正常运行时,观察玻璃观察口,无气泡冒出,空调关闭期间有气泡冒出,说明车内空调不缺制冷剂,空调继续工作时,不断冒出气泡,说明制冷剂不足,需要补充。
2、如果空调正常工作时,低压管路不冷却,就可能缺少制冷剂。
3、空调正常开启一段时间后会吹到身上,很快就会达到设定的温度,这是正常的,室外机的压缩机可以像冰箱一样关上一段时间,可以说是正常的,但如果打开后仍然不制冷,就会出现问题。
4、用温度计测量室内进风口温差,温差大于10°C,属正常现象,温差越大,格力空调的工作环境越好,约为15℃。
5、空调启动10分钟后,打开室内机面板,看到蒸发器(部分铜管与铝板换热)均匀地覆盖有露水等冷凝水,当空气湿度很高时,有很多,反之亦然。如果没有一半,可能是由于氟化物缺乏,如局部霜冻或结冰不正常。
6、触摸,如果你能用手触摸室外机,可以用手在启动后十分钟触摸它,室外机有两个铜管阀,一个铜管厚,一个铜管薄,手动两个阀门之间应该有温差,较厚的温度应低于精细温度,较冷的温度正常(温度高时冷凝水应在此处),接触室外机的热空气不是热电话,如果不热,可能是氟缺乏。
7、使用半年以上的用户可检查室内机管接头和室外机阀门是否有明显漏油迹象,如果有明显的漏油,机器就有漏油,因为油是氟溶性的,漏油一定要漏氟,漏氟一定要漏油。
8、打开空调。当加入氟化物时,空调可以直接在冷却模式下工作,由于加氟操作不能在加温状态下进行,冬季加氟时,采用加热换向阀管路的方法强制空调进入制冷状态。
低压0.4-0.5个压高压1.6左右 制冷和制热压力都一样的 只不过四通阀颠倒了一下顺序而已!低压降到0.2就要充氟了!冬天不要把氟充多了!
有两种方法可以快速判断:
1.外机:外机管道连接的地方有粗细两根管子,如果细管上有较为严重的白色结霜现象,而且一直不会消退的话,产品的冷媒不足了。
2.内机:空调制冷后开发盖子,取出过滤网,查看内机的换热器翅片上有没有结霜结冰的现象,如果一直不消退的话,就是冷媒不足不过刚开机的时候有结霜现象是正常的,等产品运转稳定后,结霜会消失,变成水珠。
你的机器几匹的,制冷还是制热,
空调一般不动,不移机不用冲制冷剂。空调制冷制热不好首先看看过滤网是否脏堵,外机(冷凝器是不是脏)一般制冷状态压力在4-5个压,制热在16-20为正常,有些机器制热在20-25个压之间。
