I need an HVAC guy or someone with HVAC experience to advise me on improving airflow to my room.
I have 2 cabs in my room. They are both totally stealth...they have no ducts or anything on the outside of the cabs since that is not a viable option for me. They can keep the temps within 8-10 degrees of the ambient temps in the room. The intakes are passive and they have small fans for exhaust. They are able to cool pretty well as they are designed but here is the problem. As they heat and expel hot air they heat up the room and therefore heat up the intake as well. I need to break that cycle by cooling this room better. The house is nice and cool in the 70F-72F range but the room can be 10 degrees warmer. This has always been a hot room so the first thing I did was to add an inline booster fan and vane switch w/ about a 465cfm free air rating. That helped a few degrees but I want about 5 more at least to be safe.
I am thinking of adding a manual damper into the system. This room is the first branch off of the trunk but it is also the longest. The register is also in an unvented gable which doesn't help.
Since this is the first branch, would it work to put a damper directly after this branch to damp flow to the colder rooms further down the trunk? I am thinking that it will help but I would like another opinion before I do it.
Another option of course is to add a window unit but I would have to pull from another circuit for more power. It would be no fun at all to have to fish a line down that wall since it is so hard to access...and it is an exterior wall too which means it is full of insulation.
Can anyone out there give me their opinion on this or have a better plan?
I would sure appreciate some help on this before I waste time on something that may be a losing cause.
