北京市综合教学楼供暖及绿洲小区换热站设计（全套含CAD图纸）.zip

摘要
本次毕业设计的任务是北京市一栋综合教学楼的供热系统施工设计及绿洲小区换热站施工设计。
,㎡。采暖部分为9层,供热除了楼梯间与大厅的所有房间。
热源采用的是市政热网,室内采暖供回水温度为85/60℃。以北京市当地的冬季室外气象参数及围护结构的热工计算参数为依据,计算出该综合教学楼的热负荷。
根据教学楼结构,房间用途和及经济性和技术可行性比较,采用了竖向分两区,各区又分两支,垂直单管顺流上供下回同程式热水采暖系统。
本次设计采用散热器供暖的采暖方式,考虑到到新型散热器--铜铝散热器较传统铸铁等散热器的优点,选用该种类型的散热器。根据教学楼内各房间负荷大小(预计算需散热器组数)及构造,将系统立管位置确定,算出各组散热器片数,做出水力计算草图并进行水力计算。
最后根据小区整体情况,进行换热站设计。

ABSTRACT
The graduation project's mission is to Beijing prehensive teaching building design and construction of heating systems heat transfer station construction design district oasis.
Teaching building building height is , gross floor area of approximately 9, square meters. Heating part of the 9-layer, heat in addition to the stairwell and hall all rooms.
Heat is used in municipal work, indoor heating supply and return water temperature of 85/60 ℃. In Beijing the local winter outdoor meteorological parameters and the thermal envelope calculation parameters as the basis to calculate prehensive teaching building heat load.
According to the teaching building structure, purpose and the room and the technical feasibility and parison, using a vertical two-zone, the district was divided into two vertical single-pipe memorial program the next time the same hot water heating system.
The design uses a radiator heating heating methods, taking into account the new radiator - copper and aluminum radiators than traditional cast iron radiators advantages, the choice of this type of radiator. According to the teaching building of the room load size (number of groups puted need radiator) and the structure of the system riser position to determine, calculate the number of each group radiator, make sketches and hydraulic calculation for hydraulic calculations.
Finally, according to the whole cell, conducting heat transfer station design.
Keywords: Heat load radiator hydraulic calculation heat transfer station
