本文为一栋医院楼的防排烟系统和自动报警系统设计书。本工程为一栋医院的病房楼，地下一层，地上十八层，建筑总高度69.5米属于一类建筑。本次消防系统设计包括对建筑物内走道和大厅的机械排烟系统设计，电梯厅、楼梯间和前室的机械加压送风系统设计，每个楼层的火灾报警、广播系统、消防电话系统、联动系统。
本建筑按照现行规范为自动报警一级保护对象，系统采用控制中心报警系统，按照要求划分了报警区域和探测区域，根据规范要求各层均布置智能型烟感探头、消防广播系统；出口处设有智能型声光报警器、手动报警按钮；按照要求在消防电梯前室、设备间、泵房、值班室、控制室等部位设置消防电话分机。消防控制室设在一层东侧并且可以直通楼外。整个控制系统包括控制主机、消防电话盘、消防广播盘、多线控制盘，并在每层设置楼层显示器。整个系统可以监控各处报警信号，并由主机处理后续的联动控制过程。
The building is defined as first-level protection object and is divided into several different alarm zones and detection zones in accordance with the Code for Design Automatic Fire AlarmSystem, andit is designed to be protected by controlcenteralarmsystem. Thedocumentcontainsthe arrangement of intelligent smoke detector, fire radio system,intelligent sound and light alarm equipment, manual alarm button. Fire telephone extensionsare installedin the fire elevator room, equipment room, pump room, duty room, control room and other parts accordance withrequirements. Thefire control room located at the east of the first floor and has a door to outside of thebuilding. Thewhole control system is consisted by a control host,afire telephonepanel,afire radiopaneland amulti-linecontrol panel.Also,there isa firemonitorwhich isset at each floor. Theentire system couldsupervisethe various alarm signals, and then process subsequent linkage controlprocess.
整栋建筑东西长约142米，南北宽约38米。楼内东西两侧各设有一部楼梯间和消防电梯并且连通地上18层和地下室（东西对称布置）；中部设有三部电梯和一部消防电梯，合用电梯厅，连通地下室至18层；中部还设有一防烟楼梯间，同样连通地下室至18层。其大致位置如图1-1所示。为方便描述，记西侧楼梯间为A楼梯间；东侧为B楼梯间；
建筑内有有两部楼梯并配有合用前室、一部防烟楼梯和一处消防电梯前室（电梯厅），这些部位分别做加压送风系统。楼梯间地下室设一个风口，以上每两层一个风口为常开型自垂百叶，前室及电梯厅为常闭型风口层层设置。风量计算方法使用压差法和和风速法并与规范比较去最大计算风量。各处风量及阻力计算和设备选型等见具体章节。
In exhaust system, the building is divided into different smoke partitions, which is considering with the fire district. Detailed naming method of smoke partition could be found in relevant sections of the firstchapter. Eachfloor is divided into three fire district and has similar structure.Thus, eachfloor is divided into three smoke partitions as well, except the eighteenthfloor. Areaof the smoke partition in eighteenth floor is toobig. Inorder to reduce the volume ofsystem, those partitions (S1-E, S3-W) at eighteenth floor is divided into three smaller partitions at last, which are named as Y1-3.Smoke exhaust system isa kind ofcentralized system which is charged with threesmoke partitionsby using three exhaustfans. All of the smokepartitions areconnected by vertical shaft. The building is divided into three parts in the horizontaldirection. Oneexhaustvent is designed in each smokepartition. Themost negative points ofthesystem areallin thebasement.For detailed information of vents, pipes, fans etc. please read relevant chapters.
Inside the building there are two stairs both of which have a front compartment, a stairwell and a fire elevator room (elevator hall). These parts are designedto set pressurized air supplysystem. Insidestairwell, there is installed one vent in basement and oneventeach two floor, and all of them are opened in peacetime. Vents in elevator hell and front compartment are installed in each floor and the type of them is normallyclosed. Thecalculation of mechanical smokesystem used the air pressure method and flow method,which were mentioned in the present code and commonly used in practice,andtake the maximum amount of them as the calculationvolume. Fordetailed information of air volume,resistancecalculation and equipment selection, etc. please readtherelevant chapter.
外地平标高-1米，一层标高±0米。地下1层，层高5.3米，主要为设备房、机房、水泵房、遗体告别室、焚化间、停尸房等。1层，层高4.3米，主要为为挂号收费室、礼品店、商务间等；13层层高4.3米，主要为病人恢复、活动区；18层为手术室，层高4.3米；其余楼层为标准层，层高均为4.3米，房间布置也均为高级病房等标准层平面图如图1-1所示，其余各层平面轮廓相似，仅内部房间划分不相同。
排烟系统根据防火分区首先划分防烟分区，并为每个防烟分区命名，具体命名方法见第一章相关章节。每层均为三个防火分区，由于楼层结构相似除十八层外每层均为三个防烟分区，每个防火分区内一个。由于十八层排烟面积过大，为降低系统排烟量将十八层两个防烟分区S1（东侧）和S3（西侧）各再分为三个防烟分区（Y1-3）。排烟系统为集中排烟方式，共三部排烟风机分别由排烟竖井连接各防烟分区，在水平方向上将大楼划分为三部分。每个防烟分区设置一个排烟口。三个部分的系统最不利点均在地下室。据计算数据选择风口、管道、风机，详细过程见具体章节。
