Content Introduction There are 3 high-rise residential buildings in this project, of which Building 1 and 3 are 33 floors high. The heating system is divided into low area, middle area and high area according to the height of the building. Building 2 is 11 floors low high. The heating system is incorporated into the low area system. The building heating area in the low area is 34500m, the building heating area in the middle area is 28000m, and the building heating area in the high area is 28000m. For radiator heating mode, the heat index per unit area is 45W/m. Low area heat load: 1553Kw, middle area heat load: 1256Kw, high area heat load: 1256Kw. The content is the reconstruction design of the heat exchange station only, including the layout plan of the heat exchange station equipment, the pipeline section, and the schematic diagram of the heat exchange station system.
