上海市某行政办公楼空调系统设计 毕业设计说明书1.docx.docxVIP

PAGE \* MERGEFORMAT60 摘要 本次设计为上海市某行政办公楼空调系统设计。该楼主要功能包括办公、会议、娱乐活动等，主楼共19层，占地面积1780平方米。本设计主要负责二、三、八、十层的系统设计。其中包含空调负荷计算，空调方案选择，空调风系统和水系统确定，风管和水管水力计算以及相关空调设备的选取等内容，并绘制出相关图纸。 本设计采用风机盘管加独立新风系统。为节省空间，新风机组采用吊顶式，办公室采用双层百叶侧送风的方式，通过计算各房间的送风状态和送风量，选择对应型号的风机盘管，由于新风不承担负荷，所以风机盘管的负荷是除去新风负荷后的负荷。 关键词 负荷，风机盘管，新风，空调系统，水力计算 Abstract This design is the air conditioning system design fora Shanghai administrative office building.The building’s main features include office,meeting,entertainment and so on.This building has 19 layers,and it covers an area of 1780 square meters.This design is mainly responsible for the Air conditioning system of the second,thethird,theeighth,and the tenth.It includes air conditioning load calculations, air conditioning program choices, and the choices of air-conditioning systems and water systems, the wind and water pipes hydraulic calculation and selection of air-conditioning equipment and other related content，at last draw relevant drawings。The design use the system of FCU and new air system.In order to save the space,the new air unit is in the ceiling,the office use double louvers to supply the air.By calculating each room air condition and air volume, select the corresponding model fan coil, as the new wind does not bear the load, so the load of fan coil doesn’t include the load of the new wind.
