Mayank,
I would imagine that the required area would change depending on
how much sun there is at any given point in time. Since it is not
possible to change the collector array constantly in an actual built
system, normally the way a simulation would be carried out is to do
some hand (or Excel) calculations to determine the area required at
a predefined solar condition (maybe at peak solar availability,
maybe some average solar availability) and then to run the
simulation with that area. If the hand/Excel calculations aren't
working, you could do trial and error - choose an area and see if it
meets the absorption machine's requirements. If not, increase the
area.
Best,
David

Sir,
I
am working on Modeling of Solar vapor absorption. In this
case
if I calculate the generator heat required in Type 107
absorption chiller for
specific capacity of chiller and useful heat from the
collector for unit area
then I can calculate the required area to completely offset
the absorption
chiller from electricity to solar energy for year around.
Please guide me in
this context. I have already done this analytically in excel
but there I
couldn’t get exact result.
Thank
you.

Re:
[TRNSYS-users] regarding changes in components input output
Mayank,
In order to add an output to a component, you need to
modify the Type's
source code and recompile the TRNDll using a Fortran
compiler. Actually
changing an input variable to an output variable is a fairly
complex procedure
because by definition, the component's performance depends
on its input values.
In this case, the performance of your collector depends on
the collector area.
If you want to change the area from an input to an output,
you also need to
figure out how you are going to calculate the collector
performance without
without knowing the collector area in advance.
Best,
David

Hello
everyone,
I
am working on solar vapor absorption machine.
For this I have to make some changes in TYPE
73 FPC input output. I need collector area in
output. How can I change input to output
please help me out.
Thank
you
