Network Hydraulics
Pressurization, pressure profiles, operating modes and control
Network hydraulics describes how mass flows, pressures and temperatures interact within a heat network. Stable pressurization, an admissible pressure profile and coordinated control are prerequisites for supplying every consumer – including the hydraulically least favourable point. This topic area covers pressurization, pressure profiles, operating modes and control concepts.
