Hi there guys,
Well, finances are just about sorted and work should commence tidying up the rear room for the plasma. That will clear the way to empty out the proposed HT room and begin construction. I have started amasssing timber for the stage, framing, screen wall and rear riser. Just need to clear the schedule (not that easy) to get some time to start building.
Before I do, I have a question regarding the cooling and warming of the room. In the photo below, you will see that I have installed a 2.75HP reverse cycle split system air conditioner.
The head unit is mounted on the RH wall of the theatre and this wall adjoins the kitchen. I will be relining this internal wall with DD, GG and clips but know that I will be losing some sound proofing by having this unit mounted on the wall. Some sound will leak out into the kitchen so I guess that's not the end of the world.
My question, however, is how to introduce fresh air into the room (or evacuate stale air) from the room. The split system has it's compressor outside so it will draw fresh air from out there, but as the room will be sealed up pretty tight (DD, GG, acoustic caulk and an acoustic door seal) how do I vent air out of the room without transmitting sound through that point. I have seen some builds with 'dead vents' or the like. Not sure how I would go about designing something for that situation and where I would mount it. The screen wall would open out to the side of my home (and not far from neighbours), the rear wall will adjoin the hallway (not far from my son's bedroom so not ideal for sound transmission), the LH wall will be about 1.5 feet from the existing wall which has two large windows which have only thin panes of glass and leak sound badly. See picture below. I will be building a fake wall inside the current wall so there is no light coming into the room and for soundproofing. You can see the existing windows in this shot.
The RH wall (where the split system is mounted) adjoins the kitchen (probably the best option).
Any advice would be greatly appreciated. Don't want to seal the whole room up only to find that I have airconditioning problems down the track.
