<p class=MsoNormal><span lang=EN-US style='color:#1F497D'>I guess, as eQuest
users, sometime we may have same thinking. You mentioned changing chiller type
to 'HEAT-PUMP' and changing the CHW loop type to '2-pipe', besides, checking Volume2.
That was what I did as well after I found the problem. I am now trying to
understand Volume 3 to see if I can find some helpful information. I can set
chiller type as 'HEAT-PUMP' and '2-pipe' CHW loop type. The main problem is,
after the prior 2 steps, the error will be shown when I try to set the
condenser type as 'air cooled'. Besides, if I set the chiller and loop type as
described, actually, the error will be shown no matter which condenser type I
choose. Please see the pictures below.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='color:#1F497D'>You also mentioned FC
2-pipe system in airside. Is that possible that you mean 4-pipe fan coil? Cause
I can only find 4-pipe FC under wizard mode. <o:p></o:p></span></p>

your choice of words, I think you intended to include the eQuest-users mailing
list and so I am CC’ing in response as this may help others. The files
you sent are fine for reviewing the question at-hand, but be aware you may want
to attach your weather file as well if you should later need help concerning

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;color:#002060'>The
system diagram and description below is helpful. You may have correctly
identified a difference in common terminology between our languages.
Rather than simply “Air-cooled heat pump,” which represents a rather broad
category of equipment/system configurations, and referencing your illustration,
I might more specifically describe your intended system as a “2-pipe fancoil
system with air-source heat pumps on heating/cooling water loop.” This
presumes the same loop is used for heating or cooling (but never both
simultaneously). </span><span lang=EN-US><o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;color:#002060'>If
that description seems accurate, I would concede that I’m not aware of a 2-pipe
configuration system option currently included in the wizards (perhaps someone
else in the list can chime in here?), but there is some direct guidance for
this system type in the help files.</span><span lang=EN-US><o:p></o:p></span></p>

lang=EN-US><o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;color:#002060'>Referencing
your file I would first explore setting your chillers to be of type ‘Heat Pump’
(HEAT-PUMP) and to change your primary CHW loop servicing the terminal fancoils
to be of type ‘2-Pipe’ (‘PIPE2’). </span><span lang=EN-US><o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;color:#002060'>Also
consider the DOE-2 help entries concerning 2-pipe loops and airside FC 2-pipe
system operations to ensure you do not miss any of the associated inputs
required, particularly the loop operation inputs which determine on what
conditions the loop will change between heating and cooling operation. A
conversation with your system/controls engineer(s) (if that is not already you)
may prove helpful on this point.</span><span lang=EN-US><o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;color:#002060'>I
would also advise 2-pipe systems by their nature have potential for “expected
unmet hours” when you have zones that require heating and cooling at the same
time served by a common loop and for a period when the loop must “switch modes”
during swing seasons. Be mindful of that nature and give consideration to
whether it will make sense to remove certain zone thermostats from the
simulation (or else evaluate what an acceptable range of coincident unmet hours
must be with all conditioned zones reporting).</span><span lang=EN-US><o:p></o:p></span></p>

confess that while I have related design/specification experience for
residential and small commercial cases, I haven’t performed a 2-pipe system

your eyes and mind open as you proceed!</span><span lang=EN-US><o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='color:#1F497D'>According to Nick's
description, do you mean that it might have chance to set an air-cooled heat
pump by adjusting the inp file of a wizard-generated DX system project? To my
knowledge, DX system can be used to simulate a VRV system that the refrigerant
will flow between the fan-coil in the room and the primary equipment outdoor. However,
what I need is an air-cooled heat pump that the refrigerant will flow only in
the primary equipment and the chilled or hot water will flow in the fan-coil
for cooling or heating the room. Since I am not sure if my expression is clear
(sorry , my pool language skill), I attach two figures for your convenience.</span><span

<p class=MsoNormal><span lang=EN-US>Dear eQuest users<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Recently, I got a problem when I try to
simulate an air-cooled heat pump. Since we cannot choose air-cooled heat pump
under wizard mode, I try to set it under detailed mode. What I have done:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>1. Switch the default 'chilled water loop'
to '2-pipe loop';<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>2. Switch the chiller type to 'heat pump';<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>3. Switch the HW loop to 'chilled water
loop' in air-side system;<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US> <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>However, when I try to switch the condenser
type to 'air cooled', an error is shown like 'assigned symbol air-cooled is of
an incompatible type'. Does anyone be confused by this situation? I guess
someone may have solution for this.<o:p></o:p></span></p>
