perhaps I need to see the project. If you are passing 22.2 dry bulb
and 14 wetbulb to Type33, it should just be spitting back the exact
same thing with a calculation of RH. I just tried that and I'm getting
an RH of 40% at 1atm pressure. When you say there is a 6.8C wetbulb, is
that on the other side of the energy wheel?<br>
