SYSPHS12 — Constraints on RelativeHumidityCalculationConstraint and HeatingCalculationConstraint not consistent between BDD Figure 79 and Parametrics Diagrams Figure 84 and Figure 88

  • Key: SYSPHS12-18
  • Status: open  
  • Source: Webel IT Australia ( Dr. Darren Kelly)
  • Summary:

    The BDD on p.92 Figure 79: Humidifier constraint blocks has for RelativeHumidityCalculationConstraint:

    {der(x)=((press/satVap)-change)/c2}
    

    The PD on p.94 Figure 84: Parametric diagram applying the relative humidity calculation constraint has for rHCC : RelativeHumidityCalculationConstraint:

    {der(x)=(press/satVap)-change}
    

    Note there is no c2.

    The BDD on p.92 Figure 79: Humidifier constraint blocks has for HeatingCalculationConstraint:

    {der(x)=tInc/c1}
    

    The PD on p.96 Figure 88: Parametric diagram applying the heating calculation constraint has for hCC : HeatingCalculationConstraint:

    {der(x)=tInc}
    

    Note there is no c1.
