color=#0000ff size=2>In eQuest, the Energy Input Ratio (EIR) can be derived from
EER or COP given for a unit or from a Standard. To correctly model such a unit,
one must subtract the fan energy for the unit to obtain the EER (EIR) of the
compressor only. This improves the input from, say, a COP of 12.3 to
15.</FONT></SPAN></DIV>

color=#0000ff size=2>What about in the case of the heat pump heating COP? Must
one subtract out the fan energy here as well, thus "worsening" the COP for the
heating side?</FONT></SPAN></DIV>
