室内热水供暖系统水力计算

室内热水供暖系统水力计算

关于室内热水供暖系统水力计算的若干问题新疆建筑设计研究院王绍瑞摘要室内供暖系统的水力计算不仅要保证各并联环路压力损失差额不大于15%,还应满足各支路水力稳定性的要求,这对于散热末端设备设有自动调控装置的系统而言是十分重要的。

完全不管室外管网资用压差条件,随意降低室内系统压力总损失设计值,然后在热力引入口处设置节流装置来消耗掉较多的富余压差的设计方式,既不利于整个管网的水力平衡,也不利于室内系统水力稳定性的保证。

本文就室内系统压力总损失设计值的确定原则和系统水力稳定性的保证提出了一些看法和措施,供同行参考。

关键词压力总损失设计值水力平衡水力稳定性0 引言室内热水供暖系统水力平衡计算的一个重要目的是使各并联环路压力损失差额不大于15%,然而,仅仅达到这一目的,并不能说我们很好地完成了系统水力计算的任务。

当室内供暖系统末端散热设备设有室温自动调控装置时,室温调控装置会随着室温的变化,频繁动作,调节末端散热支路的流量以使室温基本保持恒定。

对这样的室内供暖系统而言,减少室温调控装置动作时的相互干扰,提高系统水力稳定性同样是水力计算工作的重要目的。

当然,尽量减少系统管材的用量,也是设计者在水力计算过程中必须要考虑到的。

室内系统水力平衡度和水力稳定性的提高,都与压力总损失设计值有密切的关联。

室内供暖系统压力总损失设计值越大,越有利于提高散热末端支路压力损失占系统总损失的份额。

散热末端支路压力损失占系统压力总损失份额越大,干管占系统压力总损失份额越小,则容易实现系统水力平衡要求,同时系统水力稳定性提高。

在进行热用户室内供暖系统设计时,应首先了解室外管网提供给热用户的资用压差的大小,室内系统压力总损失设计值应按接近外管网提供的资用压差,尽可能少留富余压差的原则来确定。

当室内供暖系统压力总损失设计值低,留有过多富余压差时,虽然可以在热力引入口处设节流装置消除掉富余压差,但这样的水力计算结果不是最佳的结果,一是降低了室内系统的水力稳定性;二是多用了管材,无论从技术角度还是经济角度来讲都是不合理的。

采暖系统水力计算

采暖系统水力计算

在《供热工程》P97和P115有下面两段话:可以看出对于单元立管平均比摩阻的选择需要考虑重力循环自然附加压力的影响,试参照下面实例,分析对于供回水温60/50℃低温热水辐射供暖系统立管比摩阻的取值是多少?实例:附件6.2关于地板辐射采暖水力计算的方法和步骤(天正暖通软件辅助完成)6.2.1水力计算界面:菜单位置:【计算】→【采暖水力】(cnsl)菜单点取【采暖水力】或命令行输入“cnsL”后,会执行本命令,系统会弹出如下所示的对话框。

功能:进行采暖水力计算,系统的树视图、数据表格和原理图在同一对话框中,编辑数据的同时可预览原理图,直观的实现了数据、图形的结合,计算结果可赋值到图上进行标注。

快捷工具条:可在工具菜单中调整需要显示的部分,根据计算习惯定制快捷工具条内容;树视图:计算系统的结构树;可通过【设置】菜单中的【系统形式】和【生成框架】进行设置;原理图:与树视图对应的采暖原理图,根据树视图的变化,时时更新,计算完成后,可通过【绘图】菜单中的【绘原理图】将其插入到dwg中,并可根据计算结果进行标注;数据表格:计算所需的必要参数及计算结果,计算完成后,可通过【计算书设置】选择内容输出计算书;菜单:下面是菜单对应的下拉命令,同样可通过快捷工具条中的图标调用;[文件] 提供了工程保存、打开等命令;新建:可以同时建立多个计算工程文档;打开:打开之前保存的水力计算工程,后缀名称为.csl;保存:可以将水力计算工程保存下来;[设置] 计算前,选择计算的方法等;[编辑] 提供了一些编辑树视图的功能;对象处理:对于使用天正命令绘制出来的平面图、系统图或原理图,有时由于管线间的连接处理不到位,可能造成提图识别不正确,可以使用此命令先框选处理后,再进行提图;[计算] 数据信息建立完毕后,可以通过下面提供的命令进行计算;[绘图] 可以将计算同时建立的原理图,绘制到dwg图上,也可将计算的数据赋回到原图上;[工具] 设置快捷命令菜单;6.2.2采暖水力计算的具体操作:1.下面以某住宅楼为例进行计算:住宅楼施工图如下:2.根据施工图系统形式绘制原理图:第一步进入【设置】菜单中的【系统形式】根据施工图“供水方式”选择“下供下回”接着再根据施工图:“立管形式”选择“双管”“立管关系”选择“异程”勾选“分户计量”“采暖形式”选择“地板采暖”点击“确定”2. 第二步在【设置】菜单中的【生成框架】完成下列内容:楼层数:6层系统分支数:1分支1样式分支2样式本住宅楼样式同分支1,所以系统分支数为“1”每支分支立管数:2每楼层用户数:2每用户分支数:3(见下图单元盘管图)3. 第三步【设置】菜单中“设计条件”4. 第四步在【生成框架】对话框中点击“生成”,如下图5.第五步在树视图中依次打开“立管1”、“楼层6”、“户1”,如下图:6.第六步在上图中完成以下几项内容的输入:1)负荷:指某盘管分支(环路)热媒提供的热量。

采暖系统水力计算汇总

采暖系统水力计算汇总
在《供热工程》P97和P115有下面两段话:可以看出对于单元立管平均比摩阻的选择需要考虑重力循环自然附加压力的影响,试参照下面实例,分析对于供回水温60/50℃低温热水辐射供暖系统立管比摩阻的取值是多少?
实例:
附件6.2关于地板辐射采暖水力计算的方法和步骤(天正暖通软件辅助完成)
6.2.1水力计算界面:
根据施工图
“供水方式”选择“下供下回”
接着再根据施工图:
“立管形式”选择“双管”
“立管关系”选择“异程”
勾选“分户计量”
“采暖形式”选择“地板采暖”
点击“确定”
2.第二步在【设置】菜单中的【生成框架】完成下列内容:
楼层数:6层
系统分支数:1
分支1样式
分支2样式
本住宅楼样式同分支1,所以系统分支数为“1”
b、如右图:一个环路可能承担两个或两个以上房间,如果是这样,计算此环路所带负荷的时候,应该把所承担的房间负荷进行累加,假如某环路承担的是某个整个房间和另一个房间的一部分,如图中环路3,既承担客厅又承担部分餐厅,这时该环路负荷取那个整个房间的负荷与那个承担部分房间的部分负荷(可以用相对盘管面积,相对负荷的原则,按他们所占的面积进行取值。如果这部分靠近外围护结构,应该把其适当的放大,比如乘以1.2的修正系数,以减少实际情况与理论分析的误差。)
每支分支立管数:2
每楼层用户数:2
每用户分支数:3
(见下图单元盘管图)
3.第三步【设置】菜单中“设计条件”
4.第四步在【生成框架】对话框中点击“生成”,如下图
5.第五步在树视图中依次打开“立管1”、“楼层6”、“户1”,如下图:
6.第六步在上图中完成以下几项内容的输入:
1)负荷:指某盘管分支(环路)热媒提供的热量。
