此设计中的建筑主要房间为办公室，大多面积较小，且各房间互不连通，应使所选空调系统能够实现对各个房间的独立控制，综合考虑各方面因素，确定选用风机盘管加新风系统。在房间内布置吊顶的风机盘管，采用暗装的形式。将该集中系统设为风机盘管加独立新风系统，新风机组从室外引入新风处理到室内空气焓值，不承担室内负荷。风机盘管承担室内全部冷负荷及部分的新风湿负荷。风机盘管加独立新风系统由百叶风口下送和侧送。
在冷负荷计算的基础上完成主机和风机盘管的选型，并通过风量、水量的计算确定风管路和水管路的规格，并校核最不利环路的阻力和压头用以确定新风机和水泵。
依据相关的空调设计手册所提供的参数，进一步完成新风机组、水泵、热水机组等的选型，从而将其反应在图纸上，最终完成整个空调系统设计。
风机盘管、水泵及附属设备等设备的选型计算及确定型号。根据所给设计条件以及总冷、热负荷和已经确定的设计方案、设备形式，选择风道以及末端设备、冷热源设备等。在选型中根据不同层，不同功能所需的新风负荷，一、二层新风机组型号为BFP-6/BFP-4。风机盘管在此次设计中根据计算主要为FP-16WA、FP-12.5WA、FP-10WA、FP-8WA、FP-5WA、FP-3.5WA。
Total Design
This design for PuNa center totaling underground ventilation air conditioning system design. The building is located in Shanghai, the project for commercial buildings air conditioning engineering design, totaling about 24 meters high, is a comprehensive building, underground a second floor a total construction area of 3868 ㎡, with air conditioning covers an area of 788.6 ㎡. A second layer is 4 meters underground. Requirements for interior design in the design reference to comfort air conditioning indoor calculation parameters, the preliminary design is: summer: dry bulb temperature is 35 degrees, relative humidity 69%, wind speed 0.3 m/s or less.
Architecture in the design of the main room for office, most of the area is lesser, and each room are connected, should make the selected air-conditioning system can realize independent control of each room, considering all the factors that determine the selected fan coil plus fresh air system. In the room decorate condole of fan coil units, in the form of dark outfit. The centralized system is set to fan coil plus fresh air system independently, fresh air units from the introduction of fresh air to outdoor, indoor air enthalpy value does not undertake indoor load. Fan coil units to undertake indoor cooling load and part of all new rheumatoid load. Fan coil plus independent fresh air system consists of shutter tuyere and side to send.
Completed in cooling load calculation on the basis of the host and the selection of fan coil units, and through the air, water, calculate and determine the specifications of the duct and water pipe road, and checking the most unfavorable loop resistance and pressure head is used to determine the new fan and water pump.
According to the relevant parameters provided by the air conditioning design manual, further complete selection of fresh air units, water pump, hot water units, etc., and its reaction on the drawings, finally complete the entire air conditioning system design.
Fan coil units, pumps and equipment selection and calculation method of model such as accessories. According to the design conditions given and always cold, heat load, and has identified form of design, equipment, selection of air duct and terminal equipment, cold and heat source equipment, etc. In model selection according to the different layer, different function needed fresh air load, fresh air unit model for 1st and 2nd floors BFP/BFP 4-6. Fan coil units according to the calculation in the design mainly for FP-16WA、FP-12.5WA、FP-10WA、FP-8WA、FP-5WA、FP-3.5WA.
