The manual states to enter the REFG-ZONE-LOAD as a negative. Are
you indicating that the larger the zone load, the more unmet cooling
hours? That seems counter intuitive doesn't it?<br><br>

You might be right about that heat ending up in the space, but that
doesn’t sound right to me. I was getting an error when REFG-AUK-KW
was 0, so I reset it. I’ve actually played around with that number
quite a bit since it seems to have a large impact on the energy
consumption. I’ll revisit it again this morning. <br>
<br>
I’m talking aboiut umnet cooling load hours. The REFG-ZONE-LOAD
keyword seems to be directly related to my space loads but in the
opposite way I thought. The more REFG-ZONE-LOAD, the more system
cooling the space requires. <br>

There are a number of other REFG- keywords that depend on
REFG-ZONE-LOAD. For example:<br>
REFG-AUK-KW - takes three entries (order corresponds to REFG-ZONE-LOAD)
of the fractional rated capacity of lights, fans, anti-sweat heaters -
the default is 40% of the REFG-ZONE-LOAD - I am not entirely sure but I
believe this heat ends up in the space. <br><br>
Also, do you mean the unmet load hours are cooling load unmet or heating
load unmet?<br>

Hi All,<br>
<br>
Has anyone had experience modeling refrigeration cases? I posted a
question the other day but this one is different.<br>
<br>
So under Air-Side HVAC Zone Parameters > Refrigeration Tab, Zone Load
(REFG-ZONE-LOAD) I entered the free cooling affect from the refrigeration
cases to the space (as described in the key word help). But looking
at the SIM file, this parameter is increasing my zone loads rather than
decreasing them, and in fact is causing my space to have more unmet load
hours. Should I apply a negative number to this parameter, or is
this parameter not the ‘free cooling’ affect. <br>
<br>
<br>
That along with the Walkin Box Load under the Air-Side HVAC System
Parameter. Not sure how the program is using this value.<br>
<br>
Thanks!<br>
<br>
