Information

Example model demonstrating the use of the IBPSA components in a larger system. This model is extended in IBPSA.Fluid.Examples.FlowSystem.Simplified1, IBPSA.Fluid.Examples.FlowSystem.Simplified2, IBPSA.Fluid.Examples.FlowSystem.Simplified3. In these examples, the flow network is simplified in three steps, which reduces the size of algebraic loops.

The system model is for a hydronic system with a hot and cold water production device, each having its own circulation pump. The warm and cold supply water temperatures are selected by switching the bottom two-way valves. The building consists of a west and east wing. Each wing has multiple zones that are heated or cooled using the hydronic system. Each wing has a north and south section with a different supply temperature, which is controlled using two main three way valves. In total there are therefore four supply pipes, which are each connected to four or eight emission devices in the zones. The flow through the emission devices is controlled using two way valves. The emission device itself also generates a pressure drop, represented by components tabsX. Note that the emission devices are in the real building cooling and heating concrete slabs, but this simplified example only models their flow resistance. The control model consists of dummy inputs.
