[Equest-users] Electricity consumption by CHILLER

[Grammy]

I am also confusing this problem, and I strongly recommend you to read the
DOE-2 engineering manual, verison 2.1A, and DOE-2.2 volume 4, which can be
downloaded from eQuest web site.

On page V.35 - V.38, engineering manual, it introduces the electric
calculation of chiller, and on page 265, volume4, it introduces the chiller
variable list number, you can export the hourly data in eQuest and
calculated by hand. I am lost at this step. As i know at this place, there
is something you need to notice, the unit of assign loading (1) shall be
BTU, and electric demand (12) may be kW, then I still can't get the right
number, if you get it, please let me know how.
