  1. ORNL’s User Facilities and HVAC research Piljae Im R&D Staff Building Technologies Research & Integration Center For RTF Variable Capacity Heat Pump Subcommittee Call March 26, 2014

  2. Introduction: ORNL Building Technologies Research and Integration Center (BTRIC) http://web.ornl.gov/sci/ees/etsd/btric/pdfs/buildings_catalog.pdf http://web.ornl.gov/sci/ees/etsd/btric/fact%20sheets/buildings_broch_fin.pdf

  3. Light Commercial Building Flexible Research Platforms (FRPs)

  4. Flexible Research Platforms (FRPs) Enable Buildings to be Changed and Tested Permanent Apparatus Permanent Apparatus With Test Buildings

  5. Features of the Permanent Platforms • ‘Active’ foundation (adiabatic when ‘on’) • Structural skeleton • Provisions for attaching ‘test buildings’ • Provisions for whole-building air pressurization/leakage tests • Utility and IT (data acquisition, process control) backbones • Process control for: • Operating the active foundation, simulating occupancy, and forcing faults (e.g., filter clogs, refrigerant loss, component failures, etc.) during tests

  6. FRP research buildings Answering industry needs through research buildings and integration R&D • Evaluating emerging energy efficiency technologies in realistic test beds is an essential step before market introduction. • Environmental chambers and other lab apparatus cannot reliably impose every operating (or transient) condition encountered in a real building. • Use of occupied buildings (the living lab approach) confounds experimental results, and is intrusive, high-risk for industry, and expensive if done right. • The building industry is reluctant to embrace new design and construction techniques until they are proven with real buildings.

  7. 1st Common HVAC Approach (e.g., RTU) Retrofit Solutions

  8. 2nd Common HVAC Approach (e.g., PTHP) Retrofit Solutions

  9. 3rd Common HVAC Approach (e.g., ASHP) Retrofit Solutions

  10. Multiple HVAC systems can be operated (Only One Operates At Any Given Time)

  11. 2-story ‘research building’ example:Several manufacturers of multi-zone HVAC Rooftop VAV VRF GSHP

  12. Chambers Enable Multi-Zone System Development & Performance Characterization

  13. Chambers Reconfigure to Support Development & Characterization of Larger Capacity Units
