Title Nanjing, a commercial building air conditioning engineering design
Abstract
Nanjing,a commercial building comfort air conditioning systems engineering design .Design elements include: cooling load calculations, selection of cold and heat sources, air handling scheme selection, air terminal equipment selection, water pipe and wind pipe system design calculations and ancillary equipment selection and specification preparation and design construction mapping.By building's cooling load and the internal structure of the building, the election cooled heat pump heating and cooling systems as Air Source Heat Pump,and take it on the top of the building.One-to five-story building is a shopping mall,take the air supply mode for Full air system.Six to twenty second floor are office buildings.Select an independent fan coil air system.Select the portion of the mall ceiling type air conditioning units air handling units, fan coil units and a separate office portion juxtaposed blowing fresh air unit.Select the appropriate air terminal equipment.Reasonable layout the road of of air-conditioning water and wind.And check the feasibility of the Program.
