! function attributes:

Economizer is active, so bypass heat exchange calcs. This applies to both flat plate and rotary HX's

CondOutletTemp

BEGIN SEQUENTIAL SUBSTITUTION to handle a lot of inter-related calcs

Initialize this gas cooler for this time step

adjust regen heating coil capacity based on desiccant cycling ratio (PLR)

add logic for warmup, kickoffsimulation and doing sizing here

!LKL discrepancy with < 0?

fw if (ra > 2.0e6): error that outside range of Rayleigh number?

CALL ShowContinueErrorTimeStamp('Air volume flow rate ratio = '//TRIM(RoundSigDigits(HXAirVolFlowRatio,3))//'.') ELSE CALL ShowRecurringWarningErrorAtEnd(TRIM(OutAirUnit(OAUnitNum)%Name)//& ': Air mass balance is required by other outdoor air units, ZoneMixing, ZoneCrossMixing, or other air flow control inputs.'& , OutAirUnit(OAUnitNum)%UnBalancedErrIndex)

calculate end time of current time step

Adding up zone inlet/outlet nodes is not working correctly. When imbalance flow occurs, the difference is placed on the zone return node even when there is nothing connected to it.

Modify total heating capacity based on defrost heating capacity multiplier MaxHeatCap passed from parent object VRF Condenser and is used to limit capacity of TU's to that available from condenser

Set DataHeatGlobal heat reclaim variable for use by heat reclaim coil (part load ratio is accounted for) Calculation for heat reclaim needs to be corrected to use compressor power (not including condenser fan power)

see 'Note' under INITIAL CALCULATIONS

Node(CHWOutletNodeNum)%Temp = CHWOutletTemp Node(HWOutletNodeNum)%Temp = HWOutletTemp Node(GLHEOutletNodeNum)%Temp = GLHEOutletTemp

!LKL Discrepancy with < 0

!LKL Discrepancy < 0

fw following check on mirror shadow surface can be removed with addition of above fw check on ShadowSurfPossibleObstruction (which is false for mirror shadow surfaces)

!! Write Header lines for report

! lcsx=x3a ! lcsz=VecNormalize(x3av12a) ! lcsy=lcszx3a

fcw Is this needed?

!! Check array of DP. DpL is used for multizone air flow calculation only !! and is not for forced air calculation
