[Bldg-sim] VSD Chiller Curves

[Chien Si Harriman]

Hi there-
 
Curious if anyone out there knows anything about the chiller EIR-fPLR
curve that is inserted by default in eQuest, when a user selects a
variable frequency drive compressor?  Most of the time, the EIR-fPLR
curve is a quadratic curve based only on the PLR, but this curve is
biquadratic, with another term called dt.  Can anyone enlighten me on
which dt they are talking about here?  I can't find it in the
documentation.
 
Sincerely,
