摘 要

随着人们生活水平的提高，对室内环境温度提出了更高的要求，节能环保、安全性高等因素越发受人们的关注。特别是新中国成立以后，我国的供暖事业得到了迅速发展。一个建筑物或房间可能有各种得热和散失热量的途径。当建筑物或房间的失热量大于得热量时，为了保持室内在要求温度下的热平衡，需要由供暖通风系统补给热量，以保证室内要求的温度。为了满足现今社会的要求，对工程建筑进行供热采暖设计是更好的达到节能环保目的的重要前提。

本次课程设计的研究对象和主要内容是以热水为热媒的建筑物集中供热系统。本文首先根据基本设计资料计算了某办公大楼的热负荷，然后根据热负荷及建筑物的形式等条件，提出了供暖系统设计方案，选择布置了供暖管网系统，绘制出了该系统的平面图和系统图，还对该系统进行了水力计算，选择管径和流速，使管网系统较好地符合了水力平衡要求。最后还计算了散热器的片数，并布置了散热器。

Abstract

As people living standard rising, the indoor environment temperature put forward higher request, energy

conservation and environmental protection, safety higher factors by more people's attention. Especially after

the founding of new China, our country's heating undertakings have developed rapidly. A building or room

may have various to heat and heat loss of the way. When building or room heat loss is greater than the heat

gain, in order to keep indoor temperature in the requirements of heat balance, the heating ventilation system

supply heat, in order to assure indoor temperature requirements. In order to meet the requirements of the

modern society, the engineering construction for heating design is the better to achieve the purpose of saving

energy and environmental protection an important prerequisite.

The curriculum design of the object of study and the main content is hot water for heating medium

building centralized heating system. This paper firstly on the basis of the basic design data to calculate the

heat load of a certain office building, and then according to the thermal load and type of building conditions,

puts forward the heating system design scheme, the choice to arrange the heating pipe network system, draw

out the system plan and system diagram and the system of the hydraulic calculation, select the diameter and 课程设计

页脚内容 flow velocity, pipeline system is well consistent with the hydraulic balancing requirements. Finally, the

calculation of radiator piece number and arrangement of the radiator.

Keywords: environmental protection and energy saving; Heating design; Load calculation
