[EnergyPlus_Support] Mass flow rate problems using energy plus 1.2.2
Dear all,
I calculated a system with the new version of energy plus 1.2.2.,
which was created with/for the old version of energy plus 1.2.1,
Using version 1.2.1 there haven `t been any relevant error massages,
but using version 1.2.2 the following error massage appears:
** Warning ** Error -- Mass Flow Rate Calculation in Plant
Loop=CHILLED WATER LOOP, Outlet and Inlet differ by more than
tolerance.
** ~~~ ** Loop inlet node=CN010, flow rate=7.740642072192259E-
002
** ~~~ ** Loop outlet node=CN001, flow rate=0.154812841443845
** Severe ** Inlet parameters for plant demand side splitter are
not physically possible
** ~~~ ** Problem in input for plant demand side CHILLED
WATER LOOP
** ~~~ ** The maximum flow out of the splitter is less than
the minimum inlet flow
** ~~~ ** Flow rate inputs for the loop do not match flow
requirements of the various branches/components
** ~~~ ** Check your flow rates and make sure that flow
balances between the splitter inlet and outlets
I already controlled all my nodes, branches, mixers, splitters and
the order of the branches in the branch lists and in the mixers/
splitters. The results were ok.
After this I controlled the mass flow rates in the chilled water
loop, which is connected with two condenser loops by two chillers.
(Those chillers are controlled by two HEAT EXCHANGER:HYDRONIC:FREE
COOLING- objects), but I did not find any error.
May you have any idea, what the problem could be or could you give
me a hint to resolve this problem?
Best regards,
Patrik
