[EnergyPlus_Support] ZoneHVAC:Dehumidifier:DX and node temperatures

["fpasserini.tn@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Iâ??m modeling some dehumidifiers and Iâ??m using the object ZoneHVAC:Dehumidifier:DX



ZoneHVAC:Dehumidifier:DX,

    0:SalaRiunuoni Dehumidifier,  !- Name

    no winter,               !- Availability Schedule Name

    0:SalaRiunuoni Dehum Return,  !- Air Inlet Node Name

    0:SalaRiunuoni Dehum Supply Inlet,  !- Air Outlet Node Name

    20.8,                    !- Rated Water Removal {L/day}

    2.7,                     !- Rated Energy Factor {L/kWh}

    0.069,                   !- Rated Air Flow Rate {m3/s}

    ZoneDehumidWaterRemoval, !- Water Removal Curve Name

    ZoneDehumidEnergyFactor, !- Energy Factor Curve Name

    ZoneDehumidPLFFPLR,      !- Part Load Fraction Correlation Curve Name

    10,                      !- Minimum Dry-Bulb Temperature for Dehumidifier Operation {C}

    35,                      !- Maximum Dry-Bulb Temperature for Dehumidifier Operation {C}

    ;                        !- Off-Cycle Parasitic Electric Load {W}



The nodes are linked with the zones in the following way:



NodeList,

    0:SalaRiunuoni Air Inlet Node List,  !- Name

    0:SalaRiunuoni Dehum Supply Inlet;  !- Node 1 Name



NodeList,

    0:SalaRiunuoni Air Exhaust Node List,  !- Name

    0:SalaRiunuoni Dehum Return;  !- Node 1 Name



ZoneHVAC:EquipmentConnections,

    0:SalaRiunuoni,          !- Zone Name

    0:SalaRiunuoni Equipment,!- Zone Conditioning Equipment List Name

    0:SalaRiunuoni Air Inlet Node List,  !- Zone Air Inlet Node or NodeList Name

    0:SalaRiunuoni Air Exhaust Node List,  !- Zone Air Exhaust Node or NodeList Name

    0:SalaRiunuoni Zone Air Node,  !- Zone Air Node Name

    0:SalaRiunuoni Return Outlet;  !- Zone Return Air Node Name



Iâ??m considering the output relative to the summer design day in the .eso file.

I would aspect that temperature of â??0:SalaRiunuoni Dehum Supply Inletâ?? (Air Outlet Node Name) = â??Zone Dehumidifier Outlet Air Temperatureâ??, but I see that

temperature of â??0:SalaRiunuoni Dehum Returnâ?? (Air Inlet Node Name) = temperature of â??0:SalaRiunuoni Dehum Supply Inletâ?? (Air Outlet Node Name)

but they are different from the â??Zone Dehumidifier Outlet Air Temperatureâ?? (â??Zone Dehumidifier Outlet Air Temperatureâ?? is much higher).

Here you can see the graphs:

The zone air temperature is similar to the temperature of â??0:SalaRiunuoni Dehum Returnâ?? (Air Inlet Node Name) and to the temperature of â??0:SalaRiunuoni Dehum Supply Inletâ?? (Air Outlet Node Name) but isnâ??t equal.
