I constructed my supermarket model using Open Studio. I used a Humidity Schedule, for controlling the Sales Area space to 50% RH maximum, but the results showed no humidity control. I looked at the idf via EnergyPlus and the IDF Editor and found that the "Dehumidification Control Type" = "ConstantSensibleHeatRatio". I changed it to "Humidistat" and re-ran via OS. No change. I went back into EP and the "Dehumidification Control Type" = "ConstantSensibleHeatRatio". Running via OS, the control type automatically reverts to the default. While in EP, I changed the control type back to "Humidistat" and ran while in EP. The results showed the dehumidification works!
Does anyone know any way to run OS with Ideal Air Loads and control Humidity via a Humidistat? I really like OS's user-friendly input and excellent graphic outputs.
