Hello,

I would need to install my existing window AC on my new house in one room.
I do not plan to buy another AC this year.

My question is: could I install the AC on the lead of the attic access, with
the face down. In that way the ~exterior~ would be the attic and the AC
would push down the cold flow air. The lead for access to the attic is on
the wardrobe, which is next to my bedroom where I need the AC.

I can not install it on the existing windows, different model and size.

Thank you,
Chris

Have you given any thought to what path the condensation would take if
mounted in an incorrect manner? Does not sound like a good idea to me.

It probably will not cool too well as it needs to dissipate heat and use
fresh air to cool. If there is an attic fan to bring in air into the attic
you may get some cooling. As Ken pointed out you will probably have a
problem with condensation. I seem to recall that there are air conditioners
that sling the condensation onto the coil. If yours is one of them it will
not function correctly.

Sounds like a bad idea. The condensation has to go somewhere and
mounted facing down, that's going to be dripping down out of the
front. I'd also have doubts as to whether the compressor was
designed to run rotated 90 deg from normal and would function normally
without damage, etc.

No you will ruin the compressor it wont lubricate, it will likely
break loose and the condensation will enter the house

No, but you might install it in the usual way through a wall into a stairwell
that's open to the attic. In wintertime, close the attic door and sprinkle
water on the basement floor with a soaker hose and a solenoid valve and a 60%
humidistat and rotate the AC 180 degrees to warm the room like a heat pump
with a 3:1 COP :-)

Can always count on Nick to come up with something practical. You
think wetting the basement floor with a soaker hose to cool an
upstairs room is sound advice? Ever hear of mold, condensation on
cold pipes, wood rot, rust, etc?

To WARM the room, nitwit :-)

Sure. Happens over 60% RH.

It probably wouldn't work, as the 110-140 degree air in the attic would not
cool the condenser sufficiently. Also, what about the drip?

worked at a company where our wall mount AC was in a mechanical room
on the other side.

with little free air the AC would run constantly and cool little.
energy costs skyrocket.

OP needs to buy a new AC

A window AC unit will only work properly when installed as designed.
This generally means with the bottom almost horizontal, actually tilted
a few degrees towards the outside. That's because gravity has a large
influence on the flow of liquids, and there are three liquids involved
that would be affected by any other orientation:

1. Water.
Water condenses on the evaporator, where it's supposed to be collected
by a pan under the evaporator in the "indoor" portion, then run to the
"outdoor" side of the unit (that's what the few degrees of tilt is for).
Once in the outdoor side, it's often splashed onto the condenser by the
fan. This cools the condenser, and makes the unit more efficient. And
if there is too much water for the unit to handle, it drips off the
outside of the unit.

If you mount the unit face down, the condensate will drip back into your
room.

2. Refrigerant
The refrigerant turns from gas into liquid in the condenser. Once
liquid, it flows to the bottom of the condenser where the liquid is
then fed through the capillary tube and on to the evaporator. If the
unit is mounted face down, the liquid refrigerant will likely pool
somewhere other than the intended "bottom" of the condenser.

3. Oil
The sealed compressor housing includes some oil that lubricates the
compressor bearings, piston rings, valves, etc. If you mount the unit
face down, the reservoir of oil inside the compressor will move to
somewhere it's not supposed to be. You could get poor lubrication, or
too much oil in the cylinder during compression. You might destroy the
compressor in short order.

I can not install it on the existing windows, different model and size.

Sell the existing one, buy new one that will fit.

Your answer is NO.
Others have already explained why.

But if you planned to go thru the trouble of cutting a hole in the
ceiling, just cut a hole in the wall about 2/3 the height from the
floor. Cut between the studs, thru the siding. You'll probably have
to cut out one stud. Put a piece of 2x4 across the top and bottom of
the cut out hole to reinforce the cut stud. Add trim on inside and
outside and install the AC. This is done quite a bit in office
buildings, and it dont waste a window.
