Construction technology of low-temperature hot water floor radiant heating system

This project is the low-temperature hot water floor radiant heating project of Building 4 #. This design uses low-temperature hot water floor radiant heating system, and centralized heat source. The supply and return water temperature is 50/40 ℃, and the difference between the supply and return water temperature is 10 ℃. If the heating water temperature does not meet the requirements, a heat exchange station shall be added for regulation. The heating pipe is cross-linked polyethylene pipe PE-X, with a nominal outer diameter of 20mm, a wall thickness of 1.9mm, and a service life of 50 years. The flow rate of hot coal in the heating pipe is not less than 0.25m/s, and the system working pressure is 45KPa.

This drawing shows the design of low temperature hot water floor radiant heating system for a residential building. Including design drawings, design instructions, calculations, etc.

This drawing is the design drawing of low-temperature hot water floor radiant heating for a residential building in Shandong. Including: design description of heating change, list of main equipment and materials, description of water supply change, heating plan of basement of type A unit, heating plan of second to fifth floors of type A unit, heating plan of sixth floor of type A unit, heating plan of second to fifth floors of type B unit, heating plan of sixth floor of type B unit, and heating system diagram of type A unit.
