  • Damper Actuator Sizing Chart for Selecting HVAC Dampers

    One of the most frequent problems that technicians face is how to determine the correct torque actuator for their damper. These tables should help. First determine the size and type damper, then determine the air flow that the damper needs to open and close against. From that point, use the charts below to determine the amount of torque needed.

  • MAINTENANCE AND TESTING OF FIRE/SMOKE DAMPERS

    o Where the size of the duct permits, access doors should be at least 18 inches x 16 inches in size. o Where fire dampers are too large to allow them to be reset and the fusible link replaced from outside the duct, the access doors should be increased to at least 24 inches x 16 inches in size to allow a person to enter the duct.

  • ASHRAE Journal, visit .ashrae.org. Steen T. Taylor VAV

    duct design sizing techniques, such as a constant 0.1 in. w.g. per 100 ft friction rate (80 Pa per 100 m) for duct mains, this technique uses a higher starting velocity and friction rate and then keeps the duct main the same size for long distances, e.g., up to 60 ft (18 m). This results in lower first costs due to eliminated fittings but re-

  • Duct Design 5 — Sizing the Ducts

    When sizing by the friction rate results in too high a velocity, we size by the velocity, which results in a larger duct. But larger ducts also result in less resistance, which means we may get too much air flow in that run. What do we do about that? Install balancing dampers.
