Air conditioning in wall cavity

I am in process of building a small wooden water villa. There will be a cavity between the insulated outside wall and decorative inside oak wall. As my wife does not like the air draft caused by the air conditioning units, I was thinking about solving this by channeling the air conditioning into this cavity.

Would it be effective to install the air conditioning unit so it blows cold air into the cavity between inside and outside walls? Will this cause unwanted condensation?

Outside wall is sealed on both sides with water/vapour barrier. Building is very well insulated, I expect it to require relatively small amout of energy to cool/heat.

I would NOT blow cold air in the wall cavity. Even though the outer wall has a vapor barrier there is still moisture in the air which could condense on the interior wall. That and the oak will insulate against the cold air. Eventually it would get cool but it would be very inefficient.
