市政与环境工程系MUNICIPALANDENVIRONMENTALENGINEERINGDEPARTMENT第2章采暖系统设计2.1采暖方案的确定及热负荷的计算2.1.1设计原理及方案的确定在工程设计中，围护结构的基本耗热量是按一维稳定传热过程进行计算的，即假设在计算时间内，室内、室外空气温度和其他传热过程参数都不随时间变化。但实际上是不稳定传热。对室内温度容许有一定波动幅度的一般建筑物来说，采用稳定传热计算可以简化计算方法按基本满足要求。室外热量通过地下土壤传至室外空气的过程与平壁的传热完全不一样，故地下室侧墙传热采用地带法。根据原始资料，长兴大厦共有地上10层和地下一层进行采暖，分为两个区。高低区做垂直单管顺流式系统型式。垂直单管的优点：系统型式简单、施工方便，造价低，可适当地减轻供暖系统中经常会出现的上热下冷的现象。单管跨越系统，立管的一部分水量流进散热器，另一部分立管水量通过跨越管与散热器流出的回水混合，在流入下层散热器。与顺流式相比，由于只有部分立管水量流入散热器，在相同的散热量下，散热量的出水温度降低，散热器中热媒和室内空气的平均温差△t减小，因而所需的散热器面积比顺流式系统大一些。水平串联式。具有以下优点：（1）系统的总造价，一般要比垂直式系统低；（2）管路简单，无穿过各层楼板的立管，施工方便；（3）有可能利用最高层的辅助空间（如楼梯间、厕所等），架设膨胀水箱，不必在顶棚上专设安装膨胀水箱的房间。2.1.2热负荷计算1.围护结构的基本耗热量围护结构的基本耗热量按稳态传热计算，由手册查的：公式（2-1）式中—维护结构基本耗热量,(W)；—维护结构的传热系数，[W/(㎡•℃)]；—冬季室内设计温度，（℃）；-55- 市政与环境工程系MUNICIPALANDENVIRONMENTALENGINEERINGDEPARTMENT—温差修正系数；查手册a取1；—采暖室外计算温度。（1）的确定：会议室：18℃，地下室：10℃，指挥中心：18℃，卫生间：14℃，楼梯间：14℃，办公室：18℃。（2）的确定：根据我国现行的规范采用历年平均不保证5天的日平均温度，长春市冬季室外采暧温度：。（3）地带值的确定：由暖通空调·动力技术措施查得：地带K值的划分，直接铺设在土壤上、地面各构造层材料的导热系数W/(m•℃)的非保温地面，应平行于外墙、从外向内、每2m宽划分地带，并分别取传热系数为：第一地带:K0=0.47W/(㎡•℃)第二地带:K0=0.23W/(㎡•℃)第三地带:K0=0.12W/(㎡•℃)第四地带:K0=0.07W/(㎡•℃)2.围护结构的附加耗热量维护结构的实际耗热量会受到气象条件及建筑物情况等各种因素影响而有所增减,所以需要对其进行修正,这些修正量称为围护结构附加量.附加量有朝向修正、风力附加、外门开启附加和高度附加等。（1）朝向修正耗热量：根据实用供热空调设计手册第二版查得朝向修正率：北、东北、西北，取0～10%；东、西，取-5%；东南、西南，取-10%～-15%；南，取-15%～-30%。当建筑物受到遮挡时，还应根据遮挡情况选取朝向修正率。当窗墙面积比大于1：1时，为了与一般房间有同等的保证率，宜在窗的基本耗热量中附加10%。（2）风力附加耗热量：本工程不考虑风力附加耗热量，风力附加在计算围护结构基本耗热量时，外表面换热系数aw对应的风速约为4m/s因此，在一般情况下，不必考虑风力附加。（2）外门开启附加冷风侵入耗热量：根据手册查得，为加热开启外门时侵入的冷空气，对于短时间开启，无热风幕的外门，外门的布置情况：一道门：附加率：65n%-55- 市政与环境工程系MUNICIPALANDENVIRONMENTALENGINEERINGDEPARTMENT两道门：附加率：80n%三道门：附加率：60n%，n-建筑物的楼层数。最多取修正后耗热量的500%。（2）高度附加耗热量：根据手册查得，由于室内温度梯度的影响，往往使房间上部的传热量加大。因此规定：当房间净高超过4m时，每增加1m，附加率为2%，但最大附加率不超过15%。应注意高度附加率应加在基本耗热量和其他附加耗热量（进行风力、朝向、外门修正之后的耗热量）的总和上。3.冷风渗透耗热量考虑热压与风压联合作用，且室外风速随高度递增时的缝隙计算方法（暖通与空调设计规范规定之方法）：公式（2-2）式中—维护结构基本耗热量,(W)；—理论渗风量，m3/(m·h)；—房间某朝向上的可开启门窗缝隙的长度，m；—渗风压差的综合修正系数；—外窗、门缝隙的渗风指数，据实测得值，一般钢窗可取为0.67。公式b（2-3）式中—外门窗缝隙的渗风系数，m3/(m·h·Pab)，由《使用供热空调设计手册》表5.1-10查取；—冬季室外最多风向下的平均风速，m/s；—室外采暖计算温度下的空气密度，kg/m3；m的确定：公式（2-4）式中-55- 市政与环境工程系MUNICIPALANDENVIRONMENTALENGINEERINGDEPARTMENT—热压系数。在纯热压作用下，作用在外窗、门缝两侧的热压差占渗入或渗出总热压差的百分份额，见《使用供热空调设计手册》表5.1-11；—风压差系数。在纯风压作用下，建筑物迎背风两侧风压差的一半。当认为迎背风面的外门、窗缝隙的阻力状况相同，且迎背风面的空气动力系数各为1.0和-0.4时，△Cf可取为0.7。—在纯风压作用下渗风量的朝向修正系数，见《使用供热空调设计手册》表5.1-8；—作用于外门、窗缝隙两侧的有效热压差与有效风压差之比，见下述；—外门、窗缝隙所在高度的高度修正系数，见下述。高度修正系数Ch的计算式：公式(对大城市)（2-5）式中—计算门、窗的中心线标高，m。有效热压差与有效风压差之比C的计算式：化简后，公式（对大城市）（2-6）式中hz—纯热压作用下的建筑物中和界的标高，m，可取建筑物总高度的一半带入；tn’—建筑物内热压竖井内的空气计算温度，℃，当走廊及楼梯间不供暖时，tn’按温差修正系数取值，供暖时取为16℃或18℃；tw—室外供暖计算温度；v0—同式(2-3)把以上诸式合并，讲，代入，得到某朝向上的每米外窗，门缝隙的渗风量L(m3/h·m)的计算式。有了L后，用下式算房间的渗风量:公式（2-7）式中l同式（2-2）。-55-

市政与环境工程系MUNICIPALANDENVIRONMENTALENGINEERINGDEPARTMENT第3章给水排水系统设计3.1给水系统3.1.1给水系统分区本建筑属于综合楼，一般最低卫生器具给水配件处的静水压力宜控制在以下范围内：350~450Kpa。给水系统中，卫生器具处静水压力不得大于600Kpa。根据此原则，故将本建筑分为两个区，1—3层为低区，4—10层为高区。3.1.2给水系统的选择因城市管网常年可资用水头远不能满足高层用水的要求，故考虑到二次加压。由于目前我国消防给水系统临时高压居多，高层建筑一般都设高位水箱。但是屋顶水箱容积过大，增加建筑负荷和投资费用，若水箱容量不足，可能造成上下层同时停水。根据本建筑的特点，给水管路采用低区和高区采用变频调速水泵并联的供水方式。低区和高区的供水干管设置在地下室顶棚，低区用变频泵加压直接送至十八层，高区用变频泵加压直接送至十六层。此种供水方式用水箱储备一定水量，停水时上层可延时供水。其优点是各区供水自成系统、互不影响，供水较安全可靠，各区升压设备集中设置，便于维修、管理，水箱容积小，占地少。但是设备费用较高，维修较复杂。3.1.3给水系统的组成建筑内给水系统由引入管，给水管道，配水装置、用水设备和附件组成。此外还包括地下室水箱加压水泵。给水管道采用PPR给水管，连接方式为热熔连接，管径小于160mm的PPR管材均可采用热熔的方式连接。3.1.4给水系统的水力计算1.根据给水管路的布置，画系统草图。2.根据系统草图选择配水最不利点，确定计算管路。3.以流量的变化处为节点，从配水最不利点开始，进行节点编号，将计算管路划分成计算管段，并标出两节点间计算管段的长度。-55-

市政与环境工程系MUNICIPALANDENVIRONMENTALENGINEERINGDEPARTMENT3.2排水系统3.2.1排水系统选择的原则建筑内部排水系统的功能是将人们在日常生活和工作过程中使用过的、受到污染的水以及降落到屋面的雨水和雪水收集起来，及时排到室外。建筑内部排水系统分为污废水排水系统和屋面雨水排水系统两大类。按照污废水的来源，污废水排水系统又分为生活排水系统和工业废水排水系统，按污水与废水在排放过程中的关系，生活排水系统和工业废水排水系统又分为合流制和分流制两种体制。建筑物内下列情况下宜采用生活污水与生活废水分流的排水系统：1）建筑物使用性质对卫生标准要求较高时；2）生活污水需经化粪池处理后才能排入市政排水管道时；3）生活废水需回收利用时。下列建筑物排水应单独排水至水处理或回收构筑物；1）公共饮食业厨房含有大量油脂的洗涤废水；2）洗车台冲洗水；3）含有大量致病菌，放射性元素超过排放标准的医院污水；4）水温超过40℃的锅炉、水加热器等加热设备排水；5）用作中水水源的生活排水。总上所述，根据本建筑物的结构排水系统采用：①单立管排水系统；②地下室消防电梯机坑、泵房和消防应设集水坑，潜污泵排出；③设备层集中后排出。3.2.2排水系统的敷设原则1、居住小区排水管道最小覆土深度应根据道路的行车等级、管材受压强度、地基承载力等因素经计算确定，应符合下列要求：1）小区干道和小区组团道路下的管道，覆土深度不宜小于0．7mm。2）生活污水接户管道埋设深度不得高于土壤冷冻线以上0．15m，且覆土深度不宜小于0.3m。2、建筑物内排水管道布置应符合下列要求：1）自卫生器具至排出管的距离应最短，管道转管应最少。-99-
