哈尔滨汇来旅馆供暖系统设计 摘 要 本设计是哈尔滨汇来旅馆供暖系统设计。通过采暖系统的供热使冬季室内温度达到要求，本设计室内温度采取18℃，走廊设计温度为16℃。 设计基本步骤： 首先；确定设计基本数据，编写开题报告，绘制建筑草图，并进行采暖热负荷计算。 其次；根据热负荷和建筑物的形式选择供暖系统设计方案，确定采用机械循环同程式单管热水供热系统，会出顶层、标准层和底层采暖平面图，然后进行各层供回水温度计算，确定各房间的暖气片数，并进行了布置。 再次；绘制管路系统图，并标号，进行水力计算，将设计出的各管段管径标注在管理系统图中。 本设计的总立管设于建筑物中部的126室，至顶部分为两个环路，坡度0.003，每个回路最高处装有立式集气罐，回水管位于地下0.5m处。在引入口处外网的供回水压差为30KPa。 本设计热媒采用热水供暖95℃供水及70℃回水温度。 暖气片采用四柱813型，明装。室内供暖管道明装，支管与散热器的连接方式为同侧连接，上进下出，不考虑管道向室内散热。 通过本次设计使室内温度得到了改善，达到了设计要求，并且采用热水供暖比蒸汽供暖卫生条件好，耗能低，经济效益好。 关键词　供暖；热负荷；散热器；水力计算 The Indoor Heat-supply System Design of Harbin Hui Lai Hotel Abstract This design is to Harbin to collect hotel heating system design. By heating system of heating in winter indoor temperature meet the requirements, the design indoor temperature 18 ℃, corridor design temperature is 16 ℃. The design basic steps: In the first place. Determine the design basic data, write the opening report, drawing, drawing and heating of the heat load calculation. Secondly; Choose according to heat load and the structure of the form of heating system design scheme, the determination by mechanical cycle with single pipe hot water heating system, will be in the top layer, standard layer and ground floor heating floor plan, then each layer for the return water temperature calculation, determine the room number of the radiator, and has carried on the arrangement. Once again. Map pipeline system, and label for hydraulic calculation, the design of each section diameter annotation in the management system diagram. The design of total stand pipe in the building, room 126, in central to the top is divided into two loops, grade 0.003, each circuit of the top tank is equipped with vertical set, return pipe is located at 0.5 m on underground. For back pressure difference at the entrance to guide the network to 30 kpa. This design heat medium using hot water heating water supplies to 95 ℃ and 70 ℃ the return water temperature. Radiator appling four-post type 813, Min
