The bathroom is 30 cm lower than the living room, can the central air conditioner be placed in the b

Not good. The external unit needs to be placed outside to absorb heat and dissipate heat.

The bathroom is damp and prone to rust and leakage.

Not good. Put the bathroom, someone has to close the door, this is a common thing, the air conditioner can not play a better role, or find a place in the living room to put it.

It's not appropriate to install an air conditioner in the bathroom, they never put my air conditioner into the bathroom, the 30th point is 30 cm lower, can the central air conditioner be fried? Foreign outdoor machines can't be placed in the bathroom, they have to be placed in the bathroom, knowing that the exterior wall can, they leak water, it is not suitable to put them in the bathroom, or do they put them outside the exterior wall?

I think that the central air conditioning unit should be placed outside the wall, so that the heat in the house can be discharged to the outside, and it is not suitable to be placed in the bathroom, and the heat in the room is not suitable for discharge.

No, the external unit must be placed outside.

Put the outside machine in the bathroom? The external unit can only be placed outdoors.

Yes, it's a lot better.
