Hi Chris,<br><br>I know how to create the curves for any manufacturer's system in eQUEST. If you want to consult with me re how to do this feel free to get in touch with me.<br><br>Carol<br><br><div class="gmail_quote">

<p class="MsoNormal"><span style="color: rgb(0, 176, 80);">Hi Chris - In short, EnergyPro
v5 does VRF really well for CA Title 24 and for 90.1/LEED</span></p>
<p class="MsoNormal"><span style="color: rgb(0, 176, 80);"> </span></p>
<p class="MsoNormal"><span style="color: rgb(0, 176, 80);">Just follow the structure from
the tutorial files. You have to make sure that if an evaporator servers two
spaces with different occupancies then you have to split it into two zones and
divvy the evaporator proportionately (currently their VRF can only do one
occupancy per zone). I’ve found the LEED modules also helpful. Yes Paul
is right in that Mitsubishi helped provide the calcs. You cannot, however,
differentiate between a two-pipe or three pipe system (not sure how much it
matters for our purposes)</span></p>
<p class="MsoNormal"><span style="color: rgb(0, 176, 80);"> </span></p>
<p class="MsoNormal"><span style="color: rgb(0, 176, 80);">If working on EnergyPro v4 you
have to download a special patch created with Daikin. It was great before EP5
but I’ve found this patched v4 to be a bit buggy (and it messes with your
regular non VRF calcs – so you have to reinstall to work on regular
projects). If in CA, the patched v4 VRF version is not recognized for Title 24,
but if you’re outside CA you won’t have that problem.</span></p>
<p class="MsoNormal"><span style="color: rgb(0, 176, 80);"> </span></p>
<p class="MsoNormal"><span style="color: rgb(0, 176, 80);">Keep in mind that EnergyPro v5
still has an issue with Exception G3.1.1(a) for non-predominant conditions over
20,000 SF – so keep that in mind. It’s a known issue and is being
worked on last time I checked.</span></p>
<p class="MsoNormal"><span style="color: rgb(0, 176, 80);"> </span></p>
<p class="MsoNormal"><span style="color: rgb(0, 176, 80);">FYI – VRF is the industry
term - VRV is the same thing but for a specific manufacturer – think the
word ‘kleenex’ (VRV) w.r.t tissues (VRF)</span></p>

<p class="MsoNormal">Hi,</p><div><div></div><div class="h5">
<p class="MsoNormal"> </p>
<p class="MsoNormal">I’m a mechanical engineer working on a LEED project
where we are contemplating using a VRV/VRF system. I’ve seen several
discussions about equest and VRV/VRF; I know several people are working on this
for equest. Due to the pace of the project, and lack of time, I’ve
purchased EnergyPro software which models VRV/VRF right out of the box. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have several questions and would appreciate your thoughts.</p>
<p><span>1)<span style="font: 7pt "Times New Roman";">
</span></span>Does anyone have experience with EnergyPro? If so, do
you find it more or less flexible than eQuest?</p>
<p><span>2)<span style="font: 7pt "Times New Roman";">
</span></span>Are there any advantages of EnergyPro over eQuest?</p>
<p><span>3)<span style="font: 7pt "Times New Roman";">
</span></span>Are there any shortcomings of EnergyPro over eQuest?</p>
<p><span>4)<span style="font: 7pt "Times New Roman";">
</span></span>Any other general thoughts or observations about
energyPro.</p>
