[Equest-users] Refrigeration Modeling (2) - Zone Load

[Chris Jones]

There are a number of other REFG- keywords that depend on 
REFG-ZONE-LOAD.  For example:
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.

Also, do you mean the unmet load hours are cooling load unmet or 
heating load unmet?
