Energetic Systems of Tomorrow,from traditional wood stove to « IOT » multi-functional solution

  1. 1. ENERGETIC SYSTEMS OF TOMORROW FROM TRADITIONAL WOOD STOVE TO « IOT » MULTI-FUNCTIONAL SOLUTION Projects Optifoyer & PCC80, supported by Wallonia Project SMARTHEAT, supported by EU TEKK Tour Nov. 6th, 2017 Copyright Cenaero
  2. 2. Who are we ? – Private Research Center in Simulation, Optimisation, Data analytics • Aerospace & Transport • Manufacturing & Process industries • Built environment & Smart Cities – Stakeholders • Technological & Numerical industries • Public & Private decision makers • Business & Scientific clusters – Walloon HPC center operator (« zenobe ») Safran partnership 2007 Creation 2002 HQ in Gosselies Commercial subsidiary in Paris Composite Workshop 1 Start-up 50+ FTE 50+ % PhD 5+ Mio € of Turnover Incl. 40% industrial revenues (2015) 30+ projects R&D (2015) 20+ Regional SME collaborations (2015) Tier-1 HPC center (14,000+ cœurs) TEKK Tour Nov. 6th, 2017 Copyright Cenaero
  3. 3. Cross-fertilisation … From plane to building 1 Pilot city (Charleroi) Energy & Buildings team 10+ PPP R&D projects 30+ companies collaboration (75+ % PME) 5 (+3) jobs created Factories 4.0 Precast performance assessment tools BIM-to-manufacturing lines (HMI) Quantity take-off managment (ERP) Advanced Products & Processes Energy (Boiler, Ventilation, Fuel cell, …) Structural/thermal composites & parts Smart Buildings Support to Certification Control & data analytics Software & App New built environments Microclimate in districts Energy in building stock & grid Big/geo-data analytics TEKK Tour Nov. 6th, 2017 Copyright Cenaero
  4. 4. The challenge of Energy in Buildings • Directive for moving to NZEB ask to • ReduceReduceReduceReduce heatingheatingheatingheating needsneedsneedsneeds (NWE) … hence moving the problems on ventilation (IAQ) and overheatingoverheatingoverheatingoverheating riskriskriskrisk • Increase renewable shares … hence coping with intermittence and new activeactiveactiveactive systemssystemssystemssystems emergence • EU expecting impact for Energy in Buildings EeB H2020 program : “(…) reducing its (EU) energy consumption by as much as 50%, the construction sector is today on a critical path to help decarbonise the European economy by 2050” TEKK Tour Nov. 6th, 2017 Copyright Cenaero
  5. 5. The Stûv strategy in a nutshell – Diversify Energy source, from wood to pellet & gas – Ensure Design & Performance links as highly differenciating elements • Highly efficient combustion • Cost/Use trade-off consideration – Adapt to the market & trends • Multifunctional use in NZEB • Think beyond the building block – Be pro-active on environmental impact • Ensure low emission (trough high performance & particule filtering) • Contribute to the scientific diagnostic on air quality TEKK Tour Nov. 6th, 2017 Copyright Cenaero Today
  6. 6. Stûv P10 development: iterative diffuser design with HPC (CFD simulations) HPC - 5 designs Time~ 2designs/day Resource ~ 128 cores/design Tests - 5 designs Time ~3 days/design Resource ~1 FTE (+) Time-to-market reduced (+) Development Cost mastered (+) Simulation serves for know-how increase on dominant heat transfers in a quick mode (design de-materialised) TEKK Tour Nov. 6th, 2017 Copyright Cenaero
  7. 7. Market competitive element outcomes • Aesthetism : Optimal visual quality of the flame • Efficiency : High combustion level reached 20 x CO less than norm (CO normalised testing) • New Patent • RED DOT Award in July 2016 (Product Design – Allemagne) • Out-performing capacity demonstrated by Test Achats (September 2017) TEKK Tour Nov. 6th, 2017 Copyright Cenaero
  8. 8. Conventional design & operation tools not suited Towards a multi-fonctional and active solution TEKK Tour Nov. 6th, 2017 Copyright Cenaero
  9. 9. Making of the HPC-till-IoT link our strategy • De-materialisation mandatory due to the augmented scale (virtual prototyping) • Simulation AND data must work together towards Stove 4.0 Produce anywhere and anytime! • Our data & simulation « boxes » to play with TEKK Tour Nov. 6th, 2017 Copyright Cenaero
  10. 10. White box approach serving design & prototyping Integrated 1D /3D White Box approach = Scale managment (space & time) 3D CFD local model (comfort, stove efficiency optimisation) 1D (TRNSYS) local model (Season-based assessment, Building dynamics & regulation) Optimal design in comfort & efficiency (local/global) Regulation function estimate serving IoT/control strategy Produce anywhere and anytime! TEKK Tour Nov. 6th, 2017 Copyright Cenaero
  11. 11. • Neuronal Network trained with white box experiments (TRNSYS) • 2-para. stove heat model equation (Thermal mass & Ratio convective/radiative) • 4-para. building (Type 56) model (2 in/out EPB-compliant envel. & 2 ventil. distribution modes) • Identify the most influential parameters based on the NN • KPI : Overheating & Stove consumption Stove's thermal mass and convective ratio, impact on overheating Sensitivity in Stove consumption Explore concepts with Black Box models 6 para TRNSYS 2 KPI + Mass + Overheating lasts (hence impacts) + Convection + Overheating (questionable wrt. Local/stratification model) Limited impact of ventilation distribution MODES & envelop (since EPB compliant) Design parameters impact >80%! possible optimisation TEKK Tour Nov. 6th, 2017 Copyright Cenaero
  12. 12. • White Box Stove model (Thermal mass & Ratio convective/radiative) Grey Box replacement based on measurements on prototype RC OpenModelica Grey Box model • IN : Combustion power • OUT : Delivered power (moremoremoremore realistic value for Type56realistic value for Type56realistic value for Type56realistic value for Type56) … and use it in the full TRNSYS model Add realism to simulation with Grey Box Grey Box model parameter calibration (9 variables) OUT(expe) OUT(model) IN TEKK Tour Nov. 6th, 2017 Copyright Cenaero
