Question: Wood Bridge Climate Care, located in Toronto, has solicited the services of GTA Designs Inc. in Brampton, Ontario to design and layout the ductwork system that will provide heated air to the space shown in the drawing below. A dedicated furnace, complete with a fan will be purchased and installed below the space in an open-concept basement. The ducts will be hung from the ceiling of the basement, and appropriate flexible connections of short length will be made from the ducts to the diffusers shown in the drawing. Only supply air ducts will be required, since return air will be drawn into the fan from the open basement space. GTA Designs Inc. has conducted a heat load analysis, and the heat required to maintain each room/area in the space at 77?F is shown in the table below. Given the low winter outdoor air temperature in Toronto proper, the air will exit the diffuser grilles at 125?F to maintain the desired indoor space temperature. Design a supply air ductwork system, based on round ducts, to meet the most stringent demands for heated air. At this stage of the design, consideration of system balancing and furnace selection is not required.
