<p class=MsoNormal style='margin-bottom:12.0pt'>I also found some formulas when
tooling around in the archives the other day and could love to get comments, if
any about their utlity:<br>
<br>
EIR=(1/EER-0.012167)/((1/3.413)+0.012167)<br>
and<br>
EIR=((1/SEER*0.778+1.4)-0.012167)/((1/3.413)+0.012167)<br>
<br>
Anyone remember these that knows the source and utility? Is there one for HSPF?<br>

the detailed mode, click on the Air-Side HVAC icon at the top of your screen,
then double click on the heat pump. Under the cooling and heating tabs you will
find a Unitary Power tab where you can change your EIR.</span><o:p></o:p></p>

am still fairly new to equest and I am having a bit of trouble with setting up
my HVAC. I created a building model using the equest wizard and now I
have made a number of changes within the detailed DOE2 interface. The
building uses air source heat pumps for the HVAC and I would like to change the
EER/COP values without going back to the wizard, but I cannot figure where
these values are stored. Is there an easy way to make changes like that
within DOE2?<o:p></o:p></p>
