Meeting information

Minutes

Present: Alessandro Maccarini, Felix Bünning, Dirk Saelens, Ina De Jaeger, Annelies Vandermeulen, Bram van der Heijde, Ilaria Vigna, Konstantin Filonenko, Michael Mans, Christoph Stettler

Notes: Bram

Progress on the building perspective

  • Work done by Alessandro (Alessandro)
    • Alessandro presents his results
    • There are some slight differences between IDEAS and Alessandro's model:
      • T day and night zone, QHeating
      • Some differences in dynamics; IDEAS has slower dynamics for day zone
      • Night zone dynamics are okay.
      • Also some steady state differences
      • Will discuss further with Ina
      • Might be an issue with the controller => PID?
      • Fast cool-down: maybe due to infiltration rate/ventilation?
  • Work done by Konstantin (Konstantin)
  • Dirk introduces Ilaria (resaerch stay at KULeuven Building Physics section)
    • She will model heat demand with IDEAS library
    • Is it possible to have something beginning of June? OK
  • Action Separate meeting for the building modelling subgroup (Ina sets up doodle, see below)
    • Don't give up on two-zone model too soon
    • We don't want to miss the details in building modelling
    • TEASER can currently only cope with single zone models
      • Is it possible to make two-zone by making two separate buildings and connect them?
      • Compare both approaches?

Progress on the system perspective (Felix)

  • Pull request was made but not accepted yet
    • Action Bram has a look at this
  • Pipe dimensioning readme
    • Image of structure
    • Specification of node
    • Pipe data csv
    • Python script that creates the network
  • Network with two main branches (radial)
    • Naming of houses adheres to Ina's file
    • Could be renamed to reflect the network structure better
    • Supply and return are included in a single connection
  • Node data contains locations and peak power from Ina's simulation
  • Pipe data contains the chosen pipes with insulation thickness, length, connected nodes, total pressure loss (not Pa/m, but Pa), k values (lambda-values, not U-values).
  • Dimensioning of network is automated using this script
    • Only if peak loads coincide, but implementation for simultaneity factor is possible
  • Run the script once, and all calculations are done automatically.
  • uesgraphs package (RWTH, Marcus Fuchs) will become available this month
    • Does not include modelica compilation
  • Action set up separate meeting for network modellers (Bram sets up doodle, see below)
    • Set up document with:
      • KPI's
      • Boundary conditions
      • Other specifications
    • Bram sets up a doodle

Model checking

  • Konstantin is validating Buildings scroll heat pump
  • Genetic algorithm to check parameters with measurement data.
    • Working now

Conclusions

  • Two teams are set up
  • Heat demand team will work on finalizing and comparing results by beginning of June
  • Thermal network modelling team will set up an exercise to simulate thermal network using Felix's design tool.
    • Set up meeting to decide on KPI's and boundaries
  • Validation work can go on
  • End of June/beginning of July next coordination meeting
    • Get feedback from separate meetings
    • Action Bram sets up a doodle

Doodles for next meetings
