Hello,

I'm trying to keep the RH of a single zone building to a specific level (30%). I have added Humidification Schedule sets to the Thermal zone, and also added the DX Dehumidifier zone equipment to the thermal zone. When I ran the simulation, my heating load has gone missing, it only shows District Cooling Load, Zone Lighting and Equipment Loads.

Thanks in advance,

My model is attached below (weather file, OSM file, Sketchup File)

@Dongmin please tag the application you using ( I presume it is OS). If you can post a link to your model.

Yep I am running the OS 2.5.0.

Sorry, Im not sure how to link my model onto a post? :(

@Dongmin use one of the web service like Dropbox , create a link and post it here

@Dongmin Please explain some more what you are aiming at, as you don't have any HVAC component to heat or cool the zone. I would try to eliminate the Dehumidifier then use Ideal Air Loads with the Measure from BCL

Hi Avi, thanks for the response.

I am trying to improve the buildings thermal performance, whilst keeping the Relative Humidity level of the indoors at no more than 30%.

Your recommended approach of turning the ideal air loads indeed works, but this way it seems that I have no control over the indoor's humidity levels, as I can see from the ResultsViewer that the RH goes above 80% at times.

So I was trying to figure out how to maintain a set level of RH of a thermal zone.

Hope this helps, and thanks as always
