airconditionair question?

[msina1]

iv been told that if i want to get an air con installed in my room,
it has to be back onto a brick wall
is that true?

No..........

Not if you are talking about a split-system, with the compressor mounted externally and the evaporator mounted internally.

We have split-system air conditioning installed in two different locations - one on a brick wall and one on a timber framed wall. Both work equally effectively. They are quite ok to mount on rendered, brick, plasterboard or timber internal linings. The compressor isn't mounted directly to the wall outside - it sits on a platform mounted to the wall, so the construction method used for the wall makes no difference to the compressor.

we have one at work mounted on a steel frame that's holding up the second (mezzanine) level in a warehouse ... I think I have the photo somewhere I'll get back to ya's

in the case of a split system as long as the internal wall can support the weight of the internal unit, it can be any wall.
the external unit is generally put on a concrete slab on the ground, or in the case of a 2 story place, sometimes they are mounted to the wall with brackets.

im still a bit confused,
feel rather stupid
i was just told that they have to back onto a brick wall or something,
and my room has no room for an air con to back onto the brick wall

[Calaber]

Just think of it this way. If every house that didn't have a brick wall couldn't be air-conditioned, how do they manage to do it?

Don't be confused. Your room would be quite ok to mount an air conditioner on the wall.

[msina1]

well,
i guess i asked the question wrong really,
Would it be okay to mount it onto a wall that doesnt back onto outdoors?
sorry for the stupid questions

[Calaber]

Air conditioners need to have a drain for the condensate. You can have a wall mounted unit backing onto an internal wall, but the compressor needs to be able to drain outside the building or under it into the houses storm-water drainage.

Exactly what sort of system are you looking at - a split system or an RAC (room air conditoner or "window rattler")?

[msina1]

i hardly understand what your saying,
but a split system

I've seen plenty of timber houses fitted with split systems and wall mounted systems.

my split system is mounted on my loungeroom wall, which is gyprock over brick.
but the inside unit (evaporator & fan) is only mounted into the wooden wall studs behind the gyprock, it doesn't mount into the brick.
the compressor/condensor box sits outside the wall on the concrete.

but yeah, usually they mount them to an external wall so all the piping to the external condensor/compressor is minimal. If you have to run several meters of piping, the cost is going to be a lot higher

When the unit is in cooling mode, the indoor unit produces water. This needs to be able to drain somewhere. If it is mounted to an external wall, it is a lot easier to run a drain to outside.
It is possible to put the unit on an internal wall, but a condensate pump is required.

I'm pretty confident that's the answer you were looking for, as i do this for a living.
