If CoolT is as Vikram describes, this might be the solution to your problem. The main issue for you is to know the air flow output of the PDEC in actual operations, not under design conditions, so that other program you mentioned for sizing the PDEC is of
little help. If CoolT is not able to give you air flow rates based on the ambient conditions and the indoor air temperature, you could try building a simple two-zone model (PDEC, Building) using CONTAM and then run that stand-alone to get the air flows between
the two zones. <br>
<br>
In reference to Vikram's comment, I've said all along that the difference between the PDEC and a standard DEC<br>
is the mechanism used to drive the air across the media - using natural bouyancy forces in the first case and a mechanical fan in the second case. Once you have the air flow rate, the PDEC is actually simpler to model because there's no need to model fan efficiency
and heat gain, etc. In fact, it just takes a single effectiveness curve, or even just a constant effectiveness number.<br>

<p><span>Hello friends,</span> </p>
<p><span></span></p>
<p><span>My name is Mansi Jayswal. I am a final year student of Masters Programme at CEPT University, India. By profession I am an architect. Currently I am doing thesis on passive cooling technique (Passive down draught evaporative cooling system- PDEC ).
And try to identified that how much cooling load of HVAC system can be replaced through this system.</span>
</p>
<p><span></span></p>
<p><span>Now my query is that is it eQuest is capable to simulate such building with wind tower or PHDC (PDEC ) system? If anybody knows please kindly reply. I have very days left for final submission and I am stuck here.</span>
