Is the white plastic pipe hanging on the outside of the air conditioner broken?
The plastic pipe is discharging the condensed water, long time outside bare weathered, if your air conditioner indoor machines Water Leakage, Flanagan plastic outdoor water pipe flow does not affect the downstairs neighbors if you can not ignore it. The 2 copper tubes are the refrigerant inlet and return pipe. If a large area of leakage in the outside, affecting the cooling effect, it is best to find a maintenance for you to do the next insulation.
I do not know what you said is not the outside of the copper pipe plastic pipe is disconnected from the middle, if it is Never mind, that's just a layer of insulating pipe. It is convenient to use tape what bag prick, if not up too much trouble also never mind, just low a little (negligible) the cooling effect.
If the inside power cord is intact, there is no problem, but it's better to wrap it with plastic tape or electrical tape. The air conditioning connecting pipe is in addition to two copper pipes, in addition to the power line and the signal wire.
