空调设备出现滴水或漏水的原因是什么?

答案

参考答案:

原来运行正常的设备出现滴水,可能是因为设备的冷凝水管出现堵塞,冷凝水排不出,当设备的冷凝水盘满了之后,水就会往外流,往下滴。这种情况出现时必须对冷凝水管进行疏通,使之恢复正常。

unreadable handwriting.So I started taking my laptop to school and using it instead of paper,
books and __1__.At first I thought I was in heaven.Writing essays had become so __2__.
Copying notes took seconds.I don't have to worry about spelling __3__ and whether I have
__4__ to carry my textbooks.I was always organized,as I could not leave my books at home
anymore as they were __5__ in my machine,so you would think that it was __6__ as a learning tool.
    Unfortunately,soon I completely__7__all my ability to write,which is very limiting when still at
school.My spelling became worse as I no longer had to think about it __8__ the computer's auto
corrector.However,this wasn't what __9__ me the most.It was the fact that I was no longer
learning what I used to in class.The simple act of writing something down was a way of learning
for me,and a laptop could never __10__that.Exams started to become __11__as I no longer knew
all the words and phrases,because I __12__wasn't learning it just by typing it down.Also each
lesson was at least five minutes shorter because of the time needed to __13__ at the beginning of the
class and pack away at the end of lessons.Finding and learning notes in your computer is also less
__14__.Furthermore,a computer does not have the same __15__ of use as paper,as paper doesn't
have to be fully __16__.Finally I couldn't focus on my class __17__ I had the whole Internet at my
