Where does one find a COP for a DX cooling unit? I have only seen SEER or
EER. Then I have seen this equation from archive files, </p>
<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Calibri><span
style='font-size:11.0pt'>Cooling EIR = 0.941 * (1/(SEER/3.413)). Is this
the correct equation? It was taken from the link: <a

<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Calibri><span

style='font-size:11.0pt;font-style:italic'>Waterside – chillers</span></font></i>:
chiller EIR = 1/ COP, I was also told EIR = chiller kW *3413 / capacity.
Is this the same, which is correct?</p>
<p class=MsoNormal style='margin-left:.5in'><font size=2 face=Calibri><span
style='font-size:11.0pt'>HIR = heat input/ cooling capacity. Isn’t
COP the Output / input? So wouldn’t HIR be 1/ COP then. This is
quite confusing and going nowhere for me, would someone please clarify.</span></font></p>
