文档介绍：摘要
本毕业设计是为天津市综合办公楼中央空调系统,为工作人员创造一个舒适的环境。
本设计内容包括:冷负荷的计算;设计方案的确定;制冷机组的选择;空气处理设备的选择;风管系统和水系统的设计及水力计算;风管及水管的保温等。
根据有关标准,本设计中的办公室和会议室等全部采用风机盘管加新风的空调系统形式。室内回风经风机盘管处理后和新风单独送入各空调房间。各层风机盘管产生的凝结水统一排放到排水沟,本设计每层均设新风机组,新风由室外新风口采集,经处理后分别供给各个房间,以满足系统对新风量的需求。室内送风均采用上送上回式散流器送风。
机房位于地下室的独立制冷机房,机房选用了两台WLSBG-I-012-A系列半封闭螺杆式冷水机组。机组冷冻水供水温度为7℃,回水温度为12℃。

Abstract
The graduation design is to design the central air-conditioning system of one post office building in the city of Tianjin , so as to create fortable environment for the staffs .
It contains:the calculation of cooling load and heat load ; The determination of design scheme ; the selection of refrigeration units ; the selection of air handling equipments ; the estimation of air distribution method and the selection of relative equipments ; the insulation of air duct system and the chilled water pipes ;etc.
According to some correlation standard , the air conditioning system of the design is Fan Coil Units plus Fresh air system for all floors which are for business hall , office and meeting room . Indoor air return after the fan-coil and the new wind into the air-conditioned rooms are not effect each other. Fan-coil layers of the condensation of water discharged into the drain. There will be a new wind-generating units in each floor from every floor. The new wind from the new outlet outdoor collection, were treated after the supply of rooms to meet the needs of system . The new wind generating units in the corridor on the external walls of the East. The air is sent in on the use of casual converter air supply.
Engine room is located in the basement . the system use Two WLSBG-I-012-A series double screw water cooled water chillers . Unit chilled water supply parameters: 7℃,backwater parameters: 12℃.
Key words : a central air conditioning system of an office building , fan-coil-unit plus,fresh air system
