Does anyone know if it is possible to model a passive desiccant wheel? What I would like to model would be:
Process Air Stream:
HeatExchanger:AirToAir:SensibleAndLatent -> OutdoorAir:Mixer -> Fan:ConstantVolume -> Coil:Cooling:Water -> HeatExchanger:Desiccant:BalancedFlow -> Coil:Heating:Water
The regeneration air stream for the desiccant wheel would be the relief air stream:
OutdoorAir:Mixer -> HeatExchanger:Desiccant:BalancedFlow -> HeatExchanger:AirToAir:SensibleAndLatent
I have tried several configurations of the regen nodes without any success. I keep crashing with node errors:
** Severe ** Same component name and type has differing Node Names.
** ~~~ ** Component: HEATEXCHANGER:DESICCANT:BALANCEDFLOW, name=DESICCANT HEAT EXCHANGER
** ~~~ ** Nodes, inlet: COOLING COIL OUTLET, outlet: HX PROCESS OUTLET NODE
** ~~~ ** & Nodes, inlet: RELIEF AIR OUTLET, outlet: HX REGEN OUTLET NODE
** ~~~ ** Node Types: UNDEFINED & Process Air Nodes
** Warning ** Potential Node Connection Error for object HEATEXCHANGER:DESICCANT:BALANCEDFLOW, name=DESICCANT HEAT EXCHANGER
** ~~~ ** Node Types are still UNDEFINED -- See Branch/Node Details file for further information
** ~~~ ** Inlet Node : COOLING COIL OUTLET
** ~~~ ** Outlet Node: HX PROCESS OUTLET NODE
** Warning ** Node Connection Error for object HEATEXCHANGER:DESICCANT:BALANCEDFLOW, name=DESICCANT HEAT EXCHANGER
** ~~~ ** Process Air Nodes not on any Branch or Parent Object
** ~~~ ** Inlet Node : RELIEF AIR OUTLET
** ~~~ ** Outlet Node: HX REGEN OUTLET NODE
