Dynamic component and system simulation

Dynamic component and system simulation (TRNSYS)

Both buildings zones and thermal energy systems are modelled by a network of system components. Hereby, existing energy concepts can be optimised or new concepts can be designed and simulated. Conventional technologies at their highest state of development as well as future components are used. The dynamic simulation enables the calculation of heat flows in a sufficient resolution of time steps even over annual periods. By this method, the total energy balance as well as the impact on the indoor comfort can also be analysed at any time.

Flow simulation (CFD)

When concrete components are studied in detail, three-dimensional flow simulation is ideal. With this method, most complex flow processes with vaporizing and condensation, heat transfer and resistance to flow can be visualised and conclusions can be drawn regarding the suitability of the design. Components and plant components can be optimised or new processes can be developed and monitored. The very detailed results are, however, bought at increased calculation costs. Therefore, the coupling of the CFD method with the dynamic system simulation is advisable for many applications, in order to obtain a complete picture of the total system.
