General information
The design of central air.conditioning system for the Maoye logistics building of a shanghai company is aimed to get a comfortable working condition indoors. The total area of the building is 4955 m². The height of the first floor is 3.8 meters,and the other floor’heights are all 3.5meters. The air.condition system is designed to supply cool air in summer, and a fan coil units (FCUs)..fresh air system is selected and central screw water chillers are used to provide the chilling water needed.
Some of the main points in this design are given as follows:
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. According to the requirement, a fan coil units (FCUs)..fresh air system is appropriate. Thus，the main process equipment, i.e.
KEY WORDS: official building, central air conditioning, cooling water chiller
fan coil units (FCUs)..fresh air system
