Hello,
I am a small business owner and I've worked in hvacr for my whole career. I am fluent in service, refrigeration and custom metal fabrication. I am being contracted to fix someone else's horrible engineering problem. OK, I have a 63 unit condo bldg. in NW DC and I have to devise a solution quick. The issue: All 63 units have a mech. room with restricted space. The mechanical contractor installed Carrier furnaces without a return duct system! The only return air that's being cycled is a damn closet door with louvers! There is so many things wrong with this design, I won't insult your intelligence by listing.
I am being asked to "quiet" the system and from what I understand the new Carrier furnace has a loud blower as well. So my question is: Is there any way to direct the sound to the outside? Can I use a sound-lined return duct with a couple of in-line sound boxes to capture some of the noise? Would an exhaust fan pull any of the noise out of the mech. room?
The first thing I want to do is to remove the louvered closet door and to design a sound-lined return system. I don't know is there is any room for combustion grills but this system will at least need an over the door transfer grill or equivalent..I am also thinking about using sound line insulation to wrap the actual indoor blower assembly.
Any advice for quieting a return-less furnace room would be appreciated..
-Thanks
