<p class=MsoNormal>Hi, <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a triple loop (see attached JPEG file). The primary
PLW and the secondary HPL are heat pump loops. The HPL acts as a condenser
water loop for water-to-water heat pumps (designated RCHs). <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The RCHS provide chilled/hot water to air-handling units.
The AHUs are provided with energy recovery. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Here is what I think as an approach, and I wait for your
input please:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>- Model the heat pump loops (PLW/HPL) as a lake/well loop
(temperatures will be adjusted at a later stage, as suggested earlier in this
forum).<o:p></o:p></p>
<p class=MsoNormal>- Model the chillers as a “Heat pump” type
(probably need to adjust the part-load curves<o:p></o:p></p>
<p class=MsoNormal>- Model the AHUs as PVVT (or similar) with heating-source =
heat pump and condenser = water-cooled to get access to the energy recovery
feature; and then set the EIRs to 0.0.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any suggestions?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
