1、 I 摘 要 本次毕业设计的内容是某厂区供暖系统网管的设计，主要的目的是通过设计供暖系统 使房间在寒冷的冬天保持一种温暖的环境。 在设计中，首先简单的介绍了一下供暖系统，同时确定厂区供暖系统设计的原始资料 和数据。其次进行了采暖热负荷的计算，并对户型进行自我设计。然后算出了厂区的生活 热水供应热负荷和热负荷时间图，根据这些数据选择供暖系统的设计方案，最后方案确定 为重力循环同程式热水供暖系统。方案确定之后，进行暖气片散热片数的计算，同时计算 房间的供回水温度计算，最后进行管路的水力计算，管路管径的确定以及局部阻力损失系 数的选择。 通过本次厂区供暖系统设计使室内温度达到了设计要求，并且采用热水
2、供暖，耗能低， 经济效益好。 关键词关键词： 供暖；热负荷；散热片；供暖；热负荷；散热片；水力计算水力计算 II Abstract The graduation design of content is a plant heating system design of network management. Main goal is to design the heating system keeps the room on a cold winter a warm environment. In design, first a brief account about heating syst
3、ems, at the same time determine the factory original heating system design of information and data.Second of heating load calculation is done, type and design themselves. And then work out a factory supply of domestic hot water heat load and thermal load time, select design of heating systems based
4、on these data, final programme determined for gravity recycling program with hot-water heating systems. After the programme, radiator fins for calculating and calculate supply and return water temperature of the room, finally for hydraulic calculation of pipe, pipe diameter determines selection and loss coefficient of local resistance. Through this factory heating system design make indoor temperature meets design requirements, and the hot water heating, low energy consumption, and the economic
