Return air ducts should only be considered if 100% of the return air enters the building again and is not exhausted by the air handling device.

  • Page 35: Multiple Distributor Applications

    D. MULTIPLE DISTRIBUTOR APPLICATIONS (1) The use of multiple steam distributors can reduce the absorption distance in most situations. Distributors can be manifolded together to create a grid to achieve shorter absorption distances. (See Figure 15.) CAUTION THESE INSTALLATION GUIDELINES APPLY FOR DUCT VELOCITIES UNDER 2000 FT/MIN (610 M/MIN), PLEASE CONSULT FACTORY FOR HIGHER VELOCITIES.

If any of the ducts of the AHU conditions are changed, the absorption distance may change due to increase or decrease in duct temperatures, amount of fresh air, various outside conditions, setpoint requirements, etc.
