Dear All
I am attempting to model solar thermal assisted desiccant system in energyplus (8.6v). In output, if we sum the load of desiccant wheel (two wheels) and gain from solar system plus heater, it is not equal. Some of the severe warnings are as follow:
GetDensityGlycol: Temperature is out of range (too high) for fluid [WATER] density * * ~~~ ** ..Called From:NodeReportingCalc:COLLECTOR 1 OUTLET NODE,Temperature=[112.27], supplied data range=[0.00,100.00]
Warning * CalcNonDXHeatingCoils: Hot water coil control failed (maximum flow limits) for Dehumidifier:Desiccant:NoFans="G1_OFFICE AHU DESICCANT" * ~~~ * ...Bad hot water maximum flow rate limits * ~~~ * ...Given minimum water flow rate=0.000 kg/s * ~~~ ** ...Given maximum water flow rate=1.000 kg/s
* Severe * Inadequate heat delivered by desiccant regen coil - RESULTS INVALID! Check regen coil capacity and schedule. *** * ~~~ * Dehumidifier:Desiccant:NoFans=G1_OFFICE AHU DESICCANT *** * ~~~ * Load requested [W] from COIL:HEATING:WATER=G1_DESICCANT REGEN COIL *** * ~~~ * Max=3920.9866 *** * ~~~ * Load request exceeded delivered by [W] *** * ~~~ * Max=3873.886266
Can you provide any help in this regard.
