I'm not sure what others experience has been but:<div><br></div><div>1. I believe the heat exchanger module is basically to attach a cooling tower to a loop, nothing else</div><div><br></div><div>2. I have had trouble having eQuest properly recovery heat from a loop. I have found that using chillers, eQuest will only recover up to 100% of the chiller's hourly capacity (chillers usually reject more than 100% to the CW loop), also, sometimes much less than 100% is recovered.</div>
<div><br></div><div>3. With the loop-to-loop heat pump, I recall it being called on by a cooling load, and not by a heating load. In other words, it will reject heat to a heating loop only when a cooling load exists, but will not turn on if only a heating load exists. I'd be delighted if anyone can tell me how to operate it otherwise.</div>
<div><br></div><div>I recently completed a project that required modeling heat recovery. I ended up using the hourly outputs, and calculating in an excel spreadsheet. I did get some test models that appeared to work, but when I looked at the hourly results, sometimes only 15% of the heat was being recovered when the HW loop could've used 100% why... I don't know.</div>
<div><br></div><div>Hope this helps, and eQuest developers--I'd love to see a solution to the above issues. I think that myself and some others on this list-serve would contribute to the cost of making improvements, if possible.</div>

<p>equest-users,</p>
<p> I
am trying to connect two water loops in order to recover heat with a water to
water heat pump. I was trying to do this with a heat exchanger but the heat exchanger
module doesn't seem to be able to attach to a loop! I am a missing
something or is the heat exchanger not functional?</p>
<p> </p>
<p>Thx</p>
