文档介绍：摘要
本设计为西安锦城小区十二层商住楼集中供暖及换热站的设计,即向室内供给热量,使保持一定的室内温度,为室内人员提供舒适的生活工作环境。所有供暖系统都由热媒制备、热媒输送和热媒利用三个主要部分组成。
根据此建筑物的特点依据相关规范要求采暖需要单独引入户管,户内利用散热器采暖。本工程采用分户热计量共用立管,水平干管同程布置,户内水平单管跨越式的下供下回式采暖系统,在每层设置调节阀,进行分层调节,便于分层调节和分户计量。设计内容包括:热负荷计算;系统方案的确定;散热器计算;系统水力计算;管道保温设计等内容。
换热站的设计主要包括设备的布置,定位尺寸确定,换热器的选型,循环水泵,补给水泵的选型及辅助设备的选择计算。

Abstract
The design for the 12-mercial and residential district of Xi'an Jincheng central heating and heat transfer station design, namely indoor supply of heat, so to maintain a certain indoor temperature, to provide fortable indoor living and working environments. All heating systems prepared by the heat medium, heat medium heat medium transport and the use of three ponents.
According to the characteristics of this building heating needs in accordance with regulatory requirements related to the introduction of a separate household pipes, radiator heating indoor use. This project mon household heat metering riser, horizontal dry pipe with the way layout, indoor horizontal tube for the next time the next leap-style heating system, set up in each valve, stratified adjustment for easy layering regulation and sub-metering. Design elements include: heat load calculation; system solutions identified; heatsink calculation; system hydraulic calculation; pipe insulation design and other content.
Heat transfer station is designed mainly include equipment layout, positioning sizing, selection of heat exchangers, circulating pumps, pump selection and supply of auxiliary equipment selection and calculation.
Key words:
Central heating Radiator Machine cycle Heat transfer station
