Provision for System Testing. Provide access to the fan and motor to
measure voltage, amperage, and fan speed. Specify that all testing will be done in
accordance with the ACGIH IV Manual, Chapter 9, "Monitoring and Testing of
Energy Conservation. Incorporate applicable energy conservation
measures in the design of all industrial ventilation systems. Criteria herein minimize
volume flow rates through appropriate designs. Evaluate life cycle costs for heat
recovery systems and specify when appropriate. Refer to ASHRAE Handbook, HVAC
Systems and Equipment and MIL-HDBK-1003/3 for details.
Recirculation. Industrial ventilation systems use a large quantity of air.
Exhaust air recirculation is discouraged for most Naval industrial processes and
prohibited by OPNAVINST 5100.23 for processes generating lead and asbestos.
Follow the re-circulated air guidelines set forth in UFC 3-600-01, Design: Fire Protection
Engineering for Facilities and NFPA 654, Standard for the Prevention of Fire and Dust
Explosions from the Manufacturing, Processing, and Handling of Combustible
Particulate Solids for fire protection; the ACGIH IV Manual and ANSI Z9.7, Recirculation
of Air from Industrial Process Exhaust Systems for health protection, and the applicable
OSHA standards when recirculation is included in the design.
