某办公楼中央空调大学设计设计.docVIP

摘 要 本设计为深圳市某实业有限公司办公楼中央空调系统，拟为之设计合理的中央空调系统，为室内工作人员提供舒适的工作环境。系统采用风机盘管为主承担空调房间的冷负荷与热负荷，每个房间的吊顶内安置一到二个暗装风机盘管。新风则通过独立的新风管道先送入风机盘管，再与回风混合一起送入房间。新风机组安装于新风机房内，每一层楼放置两台新风机组负担该层所有空调房间的新风，该空调系统的优点是占用建筑面积少，可集中供冷和供热。同时各末端装置有独立的开关和调节功能，各房间的温度可独自调节与控制，且防止了空气的交叉感染。 设计内容包括：空调冷负荷的计算；空调系统的划分与系统方案的确定；冷源的选择；空调末端处理设备的选型；风系统的设计与计算；室内送风方式与气流组织形式的选定；水系统的设计、布置与水力计算；风管系统与水管系统保温层的设计；消声防振设计等内容。 本设计依据有关规范考虑节能和舒适性要求，设计的空调系统采用风机盘管——新风系统。 关键字：办公楼；中央空调；风机盘管—新风系统；性能比较。 Abstract The graduation project designs a central air conditioning system for XX official building in Shenzhen City, so as to create a comfortable work environment for the stuff. This system mainly adopts thetmantidote to undertake the air condition ro11om’s cooling loads and hot loads.Each room’s ceiling settles one or two air-conditions inside.The independent fresh air is sent into thermantidote by the independent fresh air machine firstly,and then mixed with the second-used air and sent into the room together.The independent fresh air machine is installed in the fresh air machine room.Each floor places two independent fresh air machines to support the independent fresh air for all the air conditions room in that floor.The advantage of the air condition’s system is that is can reduce the building area,it can both provide with quantity of cold and quantity of heat.Each thermantidote have the function of regulating independently,the temperature of each room can be controlled alone,and the independent fresh air can be sent into air condition room systematically. It contains: cooling load calculation; the estimation of system zoning; the selection of refrigeration units; the selection of air conditioning equipments; 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 its resistance analysis; the insulation of air duct plant and chilled water pipes; noise and vibration control; etc. According to some correlation standard, allow
