Air Conditioning System Design for XiAn Company
Abstract: This is the central air conditioning design for XiAn company。 It is aim to design a reasonable central air conditioning system and provide a comfortable working environment for the staff indoor。 By comparing the advantages and disadvantages as well as air conditioning solutions suitable for the occasion, and based on the relevant norms, considering energy efficiency and comfort requirements,the air condition system of the design is Fan coil units (FCUs)--fresh air system。This system mainly adopts the fan coil to undertake the cooling loads and hot loads。 In the ceiling of each room concealed fan coil are placement。 The fresh air set into the independent fresh air machine firstly, and then mixed with the air from the fan coil。
It contains: cooling load calculation; the estimation of system zoning; the selection of refrigeration units; the selection of air conditioning equipment; the design of air duct system and calculation; the estimation of air distribution method and the selection of relevant equipment; the design of water system and its resistance analysis; the insulation of air duct plant and chilled water pipes; noise and vibration control。 In addition, has to choose suitable auxiliary equipment for the system。
Keywords: official building; Central air conditioning; Fan coil units (FCUs)--fresh air system。
