Re: [TRNSYS-users] Relative humidity gets 100% easily

[David BRADLEY <d.bradley@tess-inc.com>]

Nguyen,
 Look at the ground temperature and other boundary temperature inputs to Type56. If they are not connected from the outputs of other components and have an initial value of 0 then that would explain why the temperature in your building is unrealistically low. If you are not able to determine the cause of the low temperature then you should send your project (*.tpf and *.b17) to your distributor for assistance.
Kind regards,
 David

Dear alls,

I'm running the simulation for a terraced building. After setting all the parameters, I run the simulation. Unfortunately, my results are very bad. The relative humidity is nearly 100% and the indoor temperature is lower than the outdoor temperature. I tried to increase the ventilation up to 15 ACH per hour, but it seems not much change. I also changed the capacitance humidity model to 10 (for typical room) but it doesn't improve much.

Is there anyone facing the same problems with me. Please share and help me deal with this.

Thank you so much!!!!

Best regrads,
