[BLDG-SIM] ERV (Energy recovery ventilation) simulation in
eQuest<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>Hi, all,</DIV>
<DIV> </DIV>
<DIV>I have problem simulating ERV in eQUSET. In the program I specified ERV
effectiveness around 72%, the results show 64% energy saving in heating but just
5% saving in cooling, even when I cut off all the fan tempetrature increase.
Anyone has experience or suggestion?. Thank you very much.</DIV>
