<P>When the cooling DT (Room-Suppy Temp) is 20 degs, every degree temp rise from the cooling coil affects the supply air by 5%. For a draw-thru system with a supply static of 8" to 9" the heat gain across the fan, the temp rise can be significant. The rule of thumb in the old days, when no one could be bothered doing these calculations manually, the temp-rise was assumed to be = 0.5 x SP. <o:p></o:p></P>
<P>The velocity upstream of the terminal box from the AHU through the unconditioned shafts of high-rise bldgs is typically about 4,000 fpm which results in low heat gain due to the high velocity. The terminal box and the low velocity ductwork is above conditioned space (typically RA plenum). If the ductwork is insulated on both sides of the TB, the rule of thumb for a temp rise through the ducts is about 1 - 2 degs which requires about a 10% increase in supply air.<o:p></o:p></P>
<P>Before anyone replies to this message saying that it has wandered off the point from the issue being discussed, I will admit the reply is an excuse to for mentioning the website. I am thinking of closing it down if there is no interest from others in developing building energy analysis course material from a full design perspective and not just using computer program. The emphasis would be on teaching Energy Efficient Building Design with project case studies. It does not quite fit in with BEMBook The objectives are in the Introduction <A href="http://bepan.info/introduction" target=1><FONT color=#0000ff>http://bepan.info/introduction</FONT></A><o:p></o:p></P>
