Thanks...Actually the standard HVAC devices are just used for ventilation...which is about 50cfm recirculating air. But I guesss the bottom line is still...not recommended huh. right?
Have anyone has any experience in any cases, where the air terminal devices/balancing dampers that are located above a cold room/warm room/environment room? May I know how can these HVAC equipments be accessed through the top of these rooms? Is there any rule of thumb that forbid locating those...
