all,<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Garamond","serif"'> I
know they always say there’s no such thing as a stupid question, but I’ve
been looking through ASHRAE 90.1 table 6.8.1 as well as I know how, and I
cannot find the required efficiency rating for a water source heat pump with a
capacity greater than 135,000 BTU/hr. We’re trying to model Multistack
heat pump/chillers, and we’re using the 70-ton model, which correlates to
about 840,000 BTU/hr. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Garamond","serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Garamond","serif"'> Has
anyone ever modeled a water source heat pump larger than 135 MBH, and if so,
which efficiency did you use? I know I’m absolutely horrible at where’s
waldo, so there’s a good chance I’ve just overlooked it. Any help
or advice is as always appreciated. Thanks.<o:p></o:p></span></p>
