[TRNSYS-users] How to implement generic days from different locations in one weatherfile?

[Philip Horn <philip.horn@ise.fraunhofer.de>]

Dear All,

I am trying to generate a set of "sample days" to represent 6 month 
(May-October -> the cooling period)  at 3 different locations (Antalya, 
Madrid, Würzburg).
therfore I compare the weatherdata and use a certain percentage of mean, 
peak, and lowest temperature and radiation from all locations.
With this I extracted 25 days that represent most common 
weatherscenarios for thos 3 locations in that period of time.

The problem now is, if I want to use this generic weatherfile 
(conatining single days from different locations and different month) 
how can I link it to Type 16?

Type 16 needs the information about the location (ONE!!) and about the 
simulation starting time in order to calculate the suns position for 
each timestep.
Obviously this is not possible...

Does anyone know how to solve this problem?

I thought about using the output of Type 16, rather than the bare 
weatherfile, to generate my generic days. This can then be fed directly 
into the collector....
This will probably work fine but limits my flexibility (i.e. changing 
the slope of the collector etc. ...)

Why am I asking this:
I want to generate training data for an artifical neural network.
In order to have a small-as-possible trainingdataset, i would like to 
use generic days rather than a huge amount of real data.
In order to generate training data for different systems (but for the 
SAME METEOROLOGICAL CONDITIONS) it makes most sense to have a set of 
generic days that is representative for the whole range of time and 
locations.

Any helpful input highly appreciated!!

Best from Freiburg,
Philip
