The vertical pipe of the heating system in this design adopts the common vertical pipe double pipe lower differential heating system, and the indoor low-temperature hot water floor radiant heating system is adopted. The constant pressure and water supplement are uniformly considered in the design of the boiler room, and the constant pressure height is 19m. The layout of heating main pipes in the basement adopts the same procedure. See the layout plan of heating main pipes for details.
Hot galvanized steel pipes are used for heating main pipes, risers and front branch pipes of water separators, and threaded connection is used when the pipe diameter is less than or equal to 100mm; When the pipe diameter is greater than 100mm, flange connection shall be adopted. When thread connection is adopted, the galvanized coating surface and exposed thread parts damaged by the sleeve thread shall be brushed with two coats of antirust paint for anti-corrosion treatment; When welding flange connection is adopted.
The drawings include: design description, basement piping layout plan, basement ventilation, smoke control plan, first floor heating plan, building thermal inlet device with ultrasonic heat meter, etc.
