The Design of Central Air-conditioning System For the Building in Shanghai
Abstract:The design of central air-conditioning system for the building in Shanghai is aimed to get a comfortable working condition indoors. The total area of the building is 5001.7 m². The height of the first floor is 4 meters, and the other seven floor heights are all 3.6 meters. The air-condition system is designed to supply cool air in summer, and fan coil units (FCUs)--fresh air system is selected and central screw water chillers are used to provide the chilling water needed. In winter, the municipal central heating system is used to supply heat and keep official room warm. To design an appropriate air-conditioning system for the building, the overall analysis is important. This includes the calculation, such as cooling load calculation, the estimation of system zoning; the design of air duct system and calculation; the estimation of air distribution method and the selection of relevant equipments; the design of water system and the analysis of its resistance losses; the plan of the insulation of air duct and chilled water pipes; etc.. Meanwhile, equipment selection is also an essential part of the design.
