<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Sorry for the repost, i have missed out the subject. My apologies.

Dear all,<br>
<div>
<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt"><br>
I am new to TRNSYS and i am currently trying to simulate a lecture hall cooling in Singapore where the weather condition is hot and humid.
<br>
But i am having problem with the humidity. I am trying to achieve a RH of 50%. However the RH i am getting from the result are in the range of 20% RH.
<br>
However if i increase the amount of outdoor air ventilation to 50% of the supply air then i am able to achieve a RH of 50 to 60%. However this does not seems to be realistic.
<br>
I have a schedule that actually runs only in the day into the late evening about 10 PM and the cooling is off till the next morning.
<br>
I have also checked in terms of the humidity ratio. However the ratio dropped very rapidly once the simulation starts which correspond to the low RH.
<br>
<br>
<br>
My question are: <br>
1) does the gain from human actually contribute moisture? Or it only contributes only the latent heat in terms of energy but not in term of moisture?
<br>
2) Does the humidity model actually affects the amount of moisture the space is able to hold?<br>
3) Where the moisture actually goes to in my model as i have a schedule running. <br>
3) I would also like to have a positive pressure inside the space, how may i go about doing this?
<br>
<br>
I have included my model.. If any one is able to kindly advice me on this. <br>
<br>
Any help is greatly appreciated! Thank you in advance. <br>
