Sorry for ur unconvenience! but i got some problems with the amount of air supply to desired room. The desired area condition are 77F, 50%Rh then,the outside area are 95F, 74%. My SHR is 0.56. When i plotted to psychrometric chart to figure out the air supply temp., I have gotten a 45F. I think...
Thank u imok2!! Your help makes me more understand about the psychrometric. But, how could I select the proper value for my design (Ambient 95Deg.F,74%Rh , Room 77Deg.F,50%Rh ,SHR = 0.9)
I saw the solution from FAQ but I would like know why we have to intersected the 95% curve on the chart, at 95%Rh (read 50 Deg.F.DB) by SHR slope line.
Thank u
