Modeling Desiccant DeHumidifiers[LINK]
How do I enter performance data for a desiccant dehumidifier?
It depends on which specific EnergyPlus object you are trying to use.
The Dehumidifier:Desiccant:NoFans object has default performance curves within the model itself that you can use. Set field A12, “Performance Model,” to DEFAULT. Alternatively, you could also obtain manufacturer’s data and develop your own curve fits, then set “Performance Model” to User Curves. See the Input Output Reference for more details.
If you want to use the Dehumidifier:Desiccant:System object, then some data set inputs for the required HeatExchanger:Desiccant:BalancedFlow:PerformanceDataType1 object are contained in the file “PerfCurves.idf” in the DataSets folder. You could also obtain manufacturer’s data and develop your own inputs for the HeatExchanger:Desiccant:BalancedFlow:PerformanceDataType1 object.
