Heating, Ventilation and Air-conditioning
Source:Scanned images
HVAC (Heating, Ventilation and Air-conditioning) systems use ventilation air ducts installed throughout a building that supply conditioned air to a room through rectangular or round outlet vents, called "diffusers"; and ducts that remove air from return-air "grilles". We create the CAD plans to show the ducting layouts for air supply and air return. |
