Design of Quaternary Heating Systems

In the course design, a centralized apartment (horizontal) water heating system with lower wiring was designed: a double-tube dead end with design temperatures tg = 90 ° С and to = 70 ° С.

Pipelines of the apartment heating system (from heating devices to PKM) are laid in cement bracing during floor preparation. The piping is made of cross-linked polyethylene PE-X (PE-Xa or REXc). Lines and risers are made of steel pipes.

The result of the heating system design is shown in the graphic part of the project.
