供热设计说明书.docVIP

摘要 本设计为西安市高速公路管理局综合楼分户计量供暖系统设计。该楼为新建建筑,剪力墙结构,地下1层,地上12层，1～2层为办公室，3～12层为住宅，3～12层的层高为3.0m。 1～2层办公室采用空调系统，本设计不考虑；3～12层住宅采用供暖系统，为本课题的设计范围。建筑物原始资料由土建专业提供,但屋顶和外墙的保温材料种类及厚度由本人设计确定。 本设计采用一户一表的系统形式，采用低温热水地板辐射供暖，热源为室外热水供热管网,其参数为95/70℃,在地下室设换热站,室内供暖系统的供水温度为45/35℃。地面加热管采用交联聚乙烯（PE-X）管，管道按设计尺寸敷设，一个环路一根管材，地下部分无接头。系统供回水干管及公用立管采用镀锌钢管，且供回水干管设置于2、3层之间的建筑夹层中。 关键词：地板辐射、分户计量、住宅、设计  Abstract The design is geared to the household-based metering heating system design of highway administration multi-purpose buildings in Xian.The Building is a new building with a layer under ground and twelve layers above the the ground and for shear wall structure. The building is 1 ~ 2 layer for office, 3 ~ 12 layer for residence, and the layer height 0f 3 ~ 12 is 3.0 m. The offices in 1 ~ 2 layers use air conditioning system, and is not this topic consideration content ; residential houses in 3 ~ 12 layers use heating system, for this topic design range. The original material of the building is provided by civil professional, The design uses a door with a heat meter system form, and use low-temperature hot water floor radiant heating system.The heat source is outdoor hot water heating pipe network.The parameters of the heat source is 95/70℃.Heat transfer stations is located in the basement.The temperature of supply and return water of household heating system is 45/35℃. The ground heating pipe is cross linked polyethylene (PE-X) pipe, layed by the design size,and a loop a pipe, for underground without joints.The supply and return water mains and public pipe riser in the system adopt galvanization steel tube. Key Words: floor radiation, household-based metering, residence, design. 目录 TOC \o 1-4 \h \z \u 绪论 6 第一章 原始资料 7 1.1 西安市气象参数 7 1.2 土建资料 7 第二章 节能计算 8 2.1 概述 8 2.2 节能计算 8 2.2.1 建筑物围护结构面积计算 8 2.2.2 建筑物基本参数计算 9 2.2.3 围护结构基本构造及传热系数计算 10 2.2.4 采暖节能建筑设计判定： 12 2.3 结论 14 第三章 热负荷的计算 15 3.1 热负荷的计算 15 围护结构耗热量 15 3.1.1.1 围护结构基本耗热量 15 3.1.1.2 附加耗热量 16 围护结构耗热量
