Hi all! I'm trying to model a very simple air conditioning device in EnergyPlus, I don't have anything specific about the system yet, apart the fact that it is just a cooling device. I use: HVACTemplate:Zone:IdealLoadsAirSystem the cooling works just fine but when I look at the relative humidity it looks like the humidity stays constantly at 45%. The climate is very hot and humid, therefore if the air is just cooled the relative humidity should rise, right? I put the Dehumidification Control Type to 'None' So I am wondering why the relative humidity is so low. Perhaps I overlooked something. Can anybody help me with this? Thanks for your help!!!
Here are my settings:
