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
