Instead through wall, thinking to put the exhaust piping of Air-
Conditioner (http://www.ebuyer.com/product/128101 ) in the chimney
My flat is on the ground floor with two more floors above me.
I understand that hot exhaust will not fall back in my flat and I do
not need to do any packing in the chimney vent.
Piping is flat 1.5cm x 9.5cm
Chimney vent is 17cm x 37cm
Exhaust end of piping I can insert in chimney vent as much as 38cm.
Perhaps in cold season when I may want to use the Air-conditioner for
heating I may want whole of Chimney vent blocked.
On examination of the vent I found lot of newspaper stuffed in the
vent by previous occupant of the flat. He must have tried to conserve
some heat in the flat by stuffing the vent with news papers.
You might -- the aircon's of that type generate negative
pressure in the room.
Which brings me to the second point -- they don't work
very well. All that air you are chucking up the chimney
(or whatever route to get it outside) has to be replaced
by air entering the house, and that brings heat in with
it. The air conditioner will spend much energy fighting
with itself over this, and not so much on reducing the
temperature for you.
If the aircon has a separate air inlet and air path for
the air which is exhausted, connect that inlet to the
outside too (separately and well away from the exhaust).
That will prevent the aircon unit drawing warm air in from
the outside to heat your rooms. Not many aircons of this
type do have separate air inlets though.

Thank you all for responding.
I have purchased http://www.ebuyer.com/product/132907
I just tested it and found it throwing hot air from back side and
throwing cool air from front-top.
The room has air vent with electrical fan on it. There are similar
units in other rooms and during summer times I let fan on one unit
fixed near floor run as the fan only drawas air in and let other vents
fixed near ceiling remain open so that air goes out from them.
Aircon is planned to be used only for couple of months in a year in
one of the rooms. Intention is to reduced temperature somewhat in the
room, the room is not going to be made air tight so air thrown out
will get replaced from other rooms.
