[esp-r] Re: FW: Normal maximum zones value 72？

[Achim Geissler]

Dear Daisy

 

increasing the number of possible zones is quite easy, I only said ¡°may
prove hazardous¡±. This is due to that going past two digits for the zone
number may have side effects in parts of the code ¨C may, mind you.

 

What you need to do is go into the file /include/building.h and change the
value of MCOM. Then make clean, Install. That¡¯s it.

 

If you have a high rise building, possibly many levels (or at least groups
of levels) have the same usage / layout etc. You could then model only one
level per such group and use multipliers for overall energy consumptions of
interest. In any case, I would try to keep a model as simple as possible.
Which accuracy will be reduced, in your opinion, for a high-rise building?
What are you simulating? What are the questions being asked?

Dear Achim£¬
        Thank you for giving answers to my question.But I wonder how to
extend the number of zones allowed  by change of source or recompiling?Would
you please tell me the specific operations?Moreover,why it is hazardous
going beyond 99 zones?What if I build a high-rise building which may be over
20 floors?Then I can only prepare 3-4 zones for each floor.If so,the
accuracy of simulation results may be worrisome.Thanks!Daisy.

Dear Daisy

 

it would maybe be possible to extend the number of zones allowed (change of
source, recompile ¨C though going beyond 99 zones may prove hazardous).
However, I would strongly recommend first checking if you cannot reduce the
number of zones in actually necessary in the model by combining thermally
similar ¡°real rooms¡± to one thermal zone. Keep in mind that bookkeeping
for such a number of zones is exponentially error prone and time consuming.

Dear all£¬
       I am trying to build a real hospital model.There are many zones in
every floor.This afternoon,I met a problem that when I built more than 72
zones,the esp-r closed itself,reminding segmentation fault,and I can't open
the configution file again,warning that zones value(73) > normal maximum
72!I have never known that.If maximum zones value is 72,how can I do to
build the hospital model with more than 300 zones for the total five
storeys?Your answers will be appreciated!Grateful thanks in advance.
    Daisy.
