Re: [EnergyPlus_Support] Performance curves of electric chiller



Hello,
 From the EPlus source code is the definition of 
DeltaTemp.  TempCondInDesign & TempEvapOutDesign are entered by the User.

!Calculate chiller performance from this set of performance equations.
!  from BLAST...Z=(TECONDW-ADJTC(1))/ADJTC(2)-(TLCHLRW-ADJTC(3))
!
        DeltaTemp= (TempCondIn   -  TempCondInDesign) / TempRiseRat &
                         - (TempEvapOut -  TempEvapOutDesign)

!  from BLAST...RCAV=RCAVC(1)+RCAVC(2)*Z+RCAVC(3)*Z**2
!
         AvailNomCapRat =   CapacityRat(1) + CapacityRat(2) * DeltaTemp       &
                                      + CapacityRat(3) * DeltaTemp ** 2


Thanks Richard Liesen
