Hello all;
I have a couple questions concerning the setup of an ice plant on eQUEST:
I have five chillers connected to my brine loop and would like to group the
rejected heat from the ice plant and dispense it to three areas: the space
heating of the building, the subfloor, and domestic hot water. I don't want
to connect a specific chiller to just one of these loops since I'd like to
have the heat recovery from all five chillers go to one area if need be, or
split it up where ever the heat is needed. That being said:
1) Is there a way to group the heat rejected from the ice plant, using
the five chillers, to a single area, and then split that heat up where it is
needed most?
2) The domestic water heater type is set to "electricity". It can also
be set to "heat pump". Can anyone explain to me what this will mean?
Please give me any advice you are willing to offer.
Thank you all and I look forward to your responses;
- Justin
Justin,
For heat recovery of this nature, I usually use equest to provide
hourly reports of my heating loads and the total chiller heat
rejection, and then post-process the data in a spreadsheet. With heat
recovery, always make sure to double check your temperatures as well
as the btus. Heat always flows from high grade to low grade.

Hi all,
Is there a place in 90.1-2007 that defines certain numbers for Baseline pressure drop?
(I've gone through the archives and addendum ac to 90.1-2004 that was incorporated in the 2007 version and can't seem to find it, because I guess there isn't such a thing as "baseline pressure drop" definition)
Can somebody chime in on the analogy for the baseline pressure drop indirectly expressed through the Appx G Table-3.1.2.9 Baseline Fan Brake Horsepower:
-I choose the type of the system (Constant or Variable)
-Per note below Table G3.1.2.9 I go back to Section 6.5.3.1.1 and define the "A" parameter in the calc
-I add all the pressure drop adjustments that apply to my applicable device for that particular system and add them to the baseline system fan power to get credit when compared to my proposed case fan power(pressure drop)?
...where I'm going with this; it's a bit confusing to use the baseline CFM and pressure drop adjustments from the proposed model to get the total baseline brake horsepower or maybe it's just Friday..
Thanks,
Nikola
