Subject: [Bldg-sim] VSD Chiller Curves

 

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,
