[EnergyPlus_Support] Re: HeatExchanger:Desiccant:BalancedFlow wrong temperature and humidity results

["tommathelin@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Hi again !

To be more accurate about my problem, I join the performance data of the Desiccant object.

For instance, with the following points and the performance datas attached:
RWI (Regen Water ratio Inlet) = 12 g/kg
RTI (Regen Temperature Inlet) = 70 °C
PWI (Process Water ratio Inlet) = 15 g/kg
PTI (Process Temperature Inlet) = 34 °C

Energyplus simulation gives me the following outlets:
RWO (Regen Water ratio Outlet) = 18.5 g/kg
RTO (Regen Temperature Outlet) = 43.4 °C
PWO (Process Water ratio Outlet) = 8.5 g/kg
PTO (Process Temperature Outlet) = 60.5 °C

whereas equations to find RWO and RTO given by the Engineering Reference document give me:
RWO (Regen Water ratio Outlet) = 21.2 g/kg
RTO (Regen Temperature Outlet) = 29.1 °C
PWO (Process Water ratio Outlet) = 5.7 g/kg
PTO (Process Temperature Outlet) = 74.9 °C

The mass flow rate was 2100 m3/h (balanced)

Is there a problem in Performance Data ?

Best Regards
TM
