Presentation Transcript

  1. ITS Ultra-Low-Mass Cooling System Enrico DA RIVA Manuel GOMEZ MARZOA WG4 Meeting - 10th April 2013 • D16 Prototype: • C4F10 thermal test results WG4 Meeting - 10th April 2013

  2. Experimental test upgrades • 6 NTCs over prototype. • Estimation of the power to room air. • New configuration of the C4F10 loop: • Full control of the refrigerant thermodynamic properties. • Full uncertainty analysis done. WG4 Meeting - 10th April 2013

  3. D16 prototype: C4F10 tests • No-Flow tests: • Power dissipated/absorbed to/from to room air • Agreement T sensors • Single-phase flow tests: • Pressure drop • Energy balance • General uncertainty • Two-Phase flow tests: • Thermal performance • Two-phase pressure drop • Compare with correlations D16 prototype summary. WG4 Meeting - 10th April 2013

  4. D16: No-Flow tests Procedure: Apply low power and record the average stave temperature. Correlate power dissipated to air vs. average stave temperature. When cooling the stave with full power, the power dissipated/absorbed to/from air can be estimated. WG4 Meeting - 10th April 2013

  5. D16: C4F10Single-phase tests Procedure: Apply low power densities (0.1 W cm-2). Ensure subcooled liquid everywhere. Check pressure drop and stave temperature. WG4 Meeting - 10th April 2013

  6. D16: C4F10Single-Phase tests Stave picks heat from room air WG4 Meeting - 10th April 2013

  7. D16: C4F10Two-phase tests WG4 Meeting - 10th April 2013
