<div><br></div>Thank you all for your quick response and Information.<div><br></div><div>Is it possible that if i use PHDC software to design the PDEC system and simulate the same building in eQuest ?? PHDC software can give me the required size of the passive down draught evaporating cooling towers for the building.</div>

<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">I believe it requires inputs that would likely be validated by a CFD model – for example, I don’t think eQUEST’s natural ventilation model allows for evaporative pre-cooling as a temperature driver for natural air exchange in a space.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">As eQUEST models each zone as a fully mixed space, and has limited air transfer between zones, you may also have trouble getting the thermal stratification from eQUEST that would typically be needed to drive natural ventilation in a PDEC.<u></u><u></u></span></p>
