Labs Session - December 4, 2015

  • Labs Updates
    • Topic for Next Month's Project - New Year's Resolutions
    • Cave Day Plan (see above)
    • Today's Project: ERV Airflows & CO2 Impact
  • Prep - Overview
    • ERV additional exhaust from Annex because of partitioning - original 100 CFM not installed?
    • Exhaust was added on main trunk at fan inlet, so would be included in low speed airflow
    • May be impacting required exhaust airflow from historic bldg enclosed spaces (toilet/conf)
    • Investigate and recommend solution, if necessary; two alternatives:
      • Speed up ERV to accommodate additional exhaust/supply - fan speed controls don't appear to alter fan speed, and both supply and exhaust appear to be combined into the same speed controller with unconnected box & 2 controllers above.
      • Move Annex exhaust duct over to variable flow branch - cost prohibitive; would have to go through wall to combine in Imaginarium.
    • Wiring diagram for ERV - mfg. schematic shows individual speed controllers on each motor (supply & exhaust) - schematic on control box panel shows no speed controllers but timer for frost control that was not installed (i.e. schematic is not accurate). Appears to be high speed controller (Vari-Speed) and low speed controller with individual wires going from each to a terminal strip in the control box (T-4 and T-5). On other side of strip, single power wire exits the box and goes to the ERV with a single local power switch on top of the unit. Power appears to be separated within the unit to go to the 2 fans, and possibly the wheel also?
  • Hands-On
    • Mark speed controller positions for supply & return fans - speeds marked on controls; note that bottom control already had a mark much higher up on the controller but was set at the line that is now displayed as a dotted line.
    • Check if fans speed up/slow down based on speed controllers - no perceptible change in speed with either rheostat adjusted higher or lower. Appears to be wired, but no change.
    • Confirm routing of exhaust duct & update as-built - confirmed; see marked up ventilation plan.
  • Brain Work
    • Is increasing fan speed an option? - not unless speed controllers are effectively connected; currently not working.
    • CO2 measured in space vs in duct
      • with fans running
      • with fans off
  • Conclusions - Suggestions
    • Exhaust airflow potential rebalance recommmendation - recommend rebalancing rather than moving duct.
    • Comment on cold weather policy and potential CO2 impact to space
