沈阳市昆山小区小高层住宅楼供暖及换热站设计.doc

摘要
随着节能减排在建设和谐社会中的推广和实施,集中供暖相对于局部供暖显示了巨大优势。本课题就对沈阳昆山小高层集中供暖系统的设计,熟悉供暖设计的程序、内容和基本原则,学****设计的方法步骤,进一步提高运算、制图和使用资料的能力,巩固所学的知识,培养这些知识解决设计问题的能力。
在设计中,通过对设计情况的了解,确定建筑物的热负荷,供暖系统形式的选择,水力计算和校核计算;以及建筑物的平面图和系统原理图。
设计中采用的是机械循环、共用立管下供下回双管垂直系统。散热器为铸铁M132,散热片安装形式为同侧的上供下回。户内为水平同程式系统。设计供回水温度为85/60℃。
关键词:集中供暖散热器机械循环双管同程
ABSTRACT
With the energy conservation and emission reduction in the construction of harmonious society, and promote and implement concentrated heating relative to the local heating showed great advantage. This topic is a three layers of zhengzhou building design of central heating system with heating design, program, content and basic principles, methods and steps of the learning design, improve operation and use of drawing and data, consolidate the knowledge, cultivating the ability of solving design problems.
In the design, through the design of buildings, determine the thermal load, the choice of the form of heating systems, hydraulic calculation and check calculation, And the building plan and system diagram.
Design is adopted by the mechanical circulation, sharing risers under dual control vertical system for the next time. Radiator made of steel, heat sink in the form of ipsilateral above water below backwater. Indoor programming system for the same water flow of horizontally. Designed for return water temperature is 85/60 ℃.
Key words: central heating radiator machine cycle double tube with the way
