panel/baseboard questions</DIV>
<DIV><BR></DIV>
<DIV><SPAN class=367382322-18102004><FONT face=Arial size=2>I am simulating a
Ground Source Heat Pump system which will provide tempered water to a radiant
slab system using eQUEST v3-5. I know that I can not use the SYSTEM TYPE
HP for a radiant slab, but I am looking for reasonable work around to
capture the yearly electric power consumption for this system. I
have tried dozens of different options, but I did not want to give up until I
heard from the experts. The building otherwise has typical air-to-water
HP systems for ventilation and cooling (the radiant heating is intended to be
disconnected from the ventilation source for comfort since this project is an
elementary school) with a ground loop for heat
rejection/heat.</FONT></SPAN></DIV>
<DIV><SPAN class=367382322-18102004><FONT face=Arial
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=367382322-18102004><FONT face=Arial size=2>So far, I have not
been able to attach either an FPH system (or baseboards) to the WLHP
circulation loop since the WLHP loop is a condenser water loop and the FPH
system (and baseboards also) can only be attached to either a hot
water loop or 2-pipe loop. Is there anyway to use or simulate a
radiant exchanger on the demand side, if the plan is not to use the air-to
water exchanger on the HP? I believe that baseboards would be an
acceptable substitute for a floor panel system if I could only find a way
to integrate them with the condenser water circulation loop. Is
there any way to define a HW loop which is connected to the WLHP circulation
loop? I have tried to define a secondary loop, but apparently the loop
type WLHP cannot have secondary loops attached. Also, would there be a
way to define the length of the WLHP loop to accurately simulate heat
loss from the loop? </FONT></SPAN></DIV>
<DIV><SPAN class=367382322-18102004><FONT face=Arial
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=367382322-18102004><FONT face=Arial size=2>Otherwise, my
guess is I would have to determine the overall heat loss from the radiant loop
given its physical properties and expected EWT and account for power used for
the HP pump primarily and condenser operation (if at all). That would
be easy to do, but I would like to know the effect that the loss
would have on the rest of the WLHP circulation loop. Is there a way
to define or schedule (either within the eQUEST model or
post-processing) the effect that the radiant heat loss would have on the
loop temperature, especially the leaving water temperature (LWT) of the
loop? I could then determine the electric power associated with the
pump (and condenser I guess) operating on the radiant system based
on occupancy and some approximation of outdoor temperature reset
control. </FONT></SPAN></DIV>

<DIV><SPAN class=367382322-18102004><FONT face=Arial size=2>Any
suggestions? I could also switch to Doe2.1E v.+100 if there's a
better work around there.</FONT></SPAN></DIV>
