Re: [EnergyPlus_Support] Re: Call for IDF Editor Suggestions

["Chandan Sharma chandangsharma@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Jason,

If you are still taking inputs, here is one more request. Can IDFEditor sort EMS programs in a different way (the way we actually write IF-ELSE ,nested loops statements etc) than rest of the objects?

For example, if the idf has following EMS program

    IF ABS_QdotReq < ABS_FullTotCapSens,  !- <none>

          Set PLR = (ABS_QdotReq - FanPowerToAir)/ (ABS_FullTotCapSens - FanPowerToAir),  !- <none>

          Set ErrorTol = 0.0005,   !- <none>

          Set Iter = 0,            !- <none>

          Set MaxIter = 30,        !- <none>

          Set Relax = 0.8,         !- <none>

          Set ABS_Error = 0.002,   !- <none>

          WHILE (ABS_Error > ErrorTol) && (Iter < MaxIter),  !- <none>

                Set OutAir_H = (PLR*FullLoadOutAirEnth) +  ((1.0-PLR)* FanOut_H),  !- <none>

                Set OutAir_W = (PLR*FullLoadOutAirHumRat) + ((1.0-PLR)*FanOut_W),  !- <none>

                Set OutletAirTemp = @TdbFnHW OutAir_H OutAir_W,  !- <none>

                Set TotCapTest = AirSupMdotDesign * (DesiredZone_H - OutAir_H),  !- <none>

                Set Error = (ABS_QdotReq - TotCapTest)/ABS_QdotReq,  !- <none>

                Set ABS_Error = @ABS Error,  !- <none>

                IF (ABS_Error > ErrorTol),  !- <none>

                      Set DelPLR = (ABS_QdotReq - TotCapTest) / ABS_FullTotCapSens,  !- <none>

                      Set PLR = PLR + Relax * DelPLR,  !- <none>

                      Set PLR = @min PLR 1.0,  !- <none>

                ENDIF,                   !- <none>

                Set Iter = Iter + 1,     !- <none>

                If (Iter == 16),         !- <none>

                      Set Relax = 0.5,         !- <none>

                ENDIF,                   !- <none>

          ENDWHILE,                !- <none>

    ELSE,                    !- <none>

          Set PLR = 1.0,           !- <none>

          Set OutAir_H = FullLoadOutAirEnth,  !- <none>

          Set OutAir_W = FullLoadOutAirHumRat,  !- <none>

          Set OutletAirTemp = FullLoadOutAirTemp,  !- <none>

    ENDIF,                   !- <none>

after sorting from IDF Editor, it becomes as follows

    IF ABS_QdotReq < ABS_FullTotCapSens,  !- A68

    Set PLR = (ABS_QdotReq - FanPowerToAir)/ (ABS_FullTotCapSens - FanPowerToAir),  !- A69

    Set ErrorTol = 0.0005,   !- A70

    Set Iter = 0,            !- A71

    Set MaxIter = 30,        !- A72

    Set Relax = 0.8,         !- A73

    Set ABS_Error = 0.002,   !- A74

    WHILE (ABS_Error > ErrorTol) && (Iter < MaxIter),  !- A75

    Set OutAir_H = (PLR*FullLoadOutAirEnth) +  ((1.0-PLR)* FanOut_H),  !- A76

    Set OutAir_W = (PLR*FullLoadOutAirHumRat) + ((1.0-PLR)*FanOut_W),  !- A77

    Set OutletAirTemp = @TdbFnHW OutAir_H OutAir_W,  !- A78

    Set TotCapTest = AirSupMdotDesign * (DesiredZone_H - OutAir_H),  !- A79

    Set Error = (ABS_QdotReq - TotCapTest)/ABS_QdotReq,  !- A80

    Set ABS_Error = @ABS Error,  !- A81

    IF (ABS_Error > ErrorTol),  !- A82

    Set DelPLR = (ABS_QdotReq - TotCapTest) / ABS_FullTotCapSens,  !- A83

    Set PLR = PLR + Relax * DelPLR,  !- A84

    Set PLR = @min PLR 1.0,  !- A85

    ENDIF,                   !- A86

    Set Iter = Iter + 1,     !- A87

    If (Iter == 16),         !- A88

    Set Relax = 0.5,         !- A89

    ENDIF,                   !- A90

    ENDWHILE,                !- A91

    ELSE,                    !- A92

    Set PLR = 1.0,           !- A93

    Set OutAir_H = FullLoadOutAirEnth,  !- A94

    Set OutAir_W = FullLoadOutAirHumRat,  !- A95

    Set OutletAirTemp = FullLoadOutAirTemp,  !- A96

    ENDIF,                   !- A97

Thanks for asking for inputs.
