Procedures

• Filters removed
• Pretest Air flow, temperature drop and coil delta
  P recorded.
• Pre-test and Post-Test Air Flow readings recorded
  using TSI VelociCalc Plus 8385.
• Surfaces and coils Vacuumed.
• Coil Cleaner applied and allowed to penetrate
  coil for 15 minutes.
• Coil rinsed with water and allowed to dry.
• Coil Treated with Coil Treatment. Condensate Pan
  Tablet installed into drain pan.
• Run Unit for at least 60 minutes and record
  Post-Test temperature drop, coil Delta P and
  airflow readings.
• Filters installed and system buttoned up

22
Energy Impact Evaluation

• Based on previous field results, a test _at_
  building 38 was conducted following the protocol
  established
• Actual air flow (Traverse) and temperature
  readings were entered into a spreadsheet derived
  from the ASHRAE fundamentals manual. This formula
  estimates total energy and makes assumptions
  difficult to quantify with multiple chiller
  installations. It has proven to be a reasonably
  accurate estimating guide.
• Given the results, additional buildings AHUs
  were cleaned and treated.

Why Part of This Program?

• Equipped Detailed measurement of whats going
  on.
• Part of the building solution. Recomissioning
• No Conflict dont sell or install replacement
  equipment
• Concerned with the whole system

32
Why Energy

• As an Important immediate concern as IAQ
• Yearly repeat program maintains gains, air
  balancing independently confirms efficiency
• Further strengthens customer relationship, most
  maintenance is a cost, not R.O.I.
• Ability to more easily be incorporated in this
  years budget. Positive energy step that can be
  implemented now.
