Thank you, thank you very much.
I'm preparing my memoiry of master i'm special in mechanic engeneering of
thermal power, my memoiry is about ISCC integrated solai combine cycle
systeme, if you have in exemple projet in transys about this send it please
to study it

>> Hello everybody,
>>
>> I am new at trnsys-users.
>> Currently I`m modeling an already existing solar heating system (for hot
>> water).
>> In this system the loading pump is activated by a time delay of 4 minutes
>> (after solar pump is launched).
>> I tried to model this as follows:
>>
>> - simulation time step: 2 minutes
>> - storage of the control signal of the solar pump over the last two time
>> steps by means of type 93 (input value recall)
>> - if the control signal of the solar pump is "1" in the stored two time
>> steps, then the loading pump is launched.
>>
>> It works (tried by a simple example deck) but does it also works in
>> context with a quite big deck (120 m² apertur area, 2 continuous
>> controllers)?
>> I`m concerned about that the small time step of 2 minutes could cause
>> problems (for example oscillations of the controllers).
>> Could this work or have someone of you another idea how i can solve this
>> problem?
>>
>> Thanks a lot.
>> Best regards.

>> Dear all,

>> 1. Please see the ATTACHED.
>>
>> Based on the Manual, B6_BAL should be always 0, but here i think its

>> it's not 0, PLEASE tell me some possible reasons about it.
>> 1_B6_BAL = - 1_B6_DQWALLdt- 1_B6_QCOMI+ 1_B6_QCOMO+
>> 1_B6_QRADGI+ 1_B6_QRADGO- 1_B6_QALG
>>
>> -8.180E-13 -3.838E+03 2.683E-03 -3.838E+03
>> 0.000E+00 0.000E+00 0.000E+00
>> 2. B6_DQWALLdt in Manual is change of internal energy of surface, but it's
>> a little abstract. Here I only used the heatings in TRNBUILD, no other
>> internal gains. PLEASE give me some examples about change of internal energy
>> of surface. Is it energy Generation of Wall etc.? Why here is minus
>> (-3.838E+03)? What's difference between B6_DQWALLdt and B6_QCOMO? Why here
>> they are the same? Is there some reasons?
>>
>> 3. I think B6_QCOMI is some heat flux enter into inside of wall such as
>> the heat from the heatings of indoor and the solar radiation, Is it right?
>> B6_QCOMO is heat loss from the wall outside, Is it right? If wrong, PLEASE
>> tell me what are their meaning.
