<DIV><FONT face=Arial><FONT size=2><FONT><SPAN class=359435122-24012006>Hi! I am
trying to model a rotary desiccant wheel dehumidifier, hence Type 683 was
chosen. In this model, the required inputs </SPAN></FONT>are the process
air and regeneration air<SPAN class=359435122-24012006> </SPAN>stream mass flow
rates, the process stream inlet conditions (dry bulb temperature and absolute
humidity<SPAN class=359435122-24012006> </SPAN>ratio), the desired process
stream outlet humidity ratio, and the regeneration stream inlet absolute<SPAN
class=359435122-24012006> </SPAN>humidity ratio<SPAN class=359435122-24012006>.

<DIV><FONT face=Arial><FONT size=2><SPAN class=359435122-24012006>However, I
would like to have the regeneration stream inlet temperature to be
specified by the user and the process air outlet humidity ratio to be calculated
by the model (i.e. not a set point). This could not be done in this model. Have
anyone come across this problem before and developed a new model to suit this
requirement?</SPAN></FONT></FONT></DIV>
