Amit,
TRNSYS can use a lot of different weather file formats. If you are not finding the location you want, make sure that you have installed the weather data archive (which is a download separate from the Trnsys installer download). If you still do not find what you are looking for, I would recommend that you look online for EnergyPlus weather data files. They are numerous and not hard to find.
kind regards,
David
Hello Everyone,
I am working a project on hybrid solar PV and Diesel Engine performance. for this i need my location weather data which is not present in TRNSYS weather file. How can i use another weather data file or how can i use type 99 for my location weather generation?

Subject: [TRNSYS-users] Solar gain of a surface
Hi everyone,
i want to calculate solar gain/ solar radiation from specific window. actually i want to see the effect of different slope angle ranging from 15 - 40 degree of window. Actually trend should be like between 20 to 30 degree solar radiation should be maximum. but as i am increasing angle radiation gain/m2 increases. i am using (NTYPE 79, 80, 81, 64) . i dont know which output i should use??
Note:: when i check solar radiation output direct at all angles calculated by TYPE 16(radiation processor) it gives required trend. trend should be same when apple this radiation to the building.

Subject: [TRNSYS-users] Type 94, maximum power
Dear TRNSYS USERS,
I am trying to understand the performance of Type 94 (Photovoltaic module).
I kept the default parameters, in particular: Current at maximum power point = 5.9 A, and Voltage at maximum power point = 17 V.
Then I forced the total radiation on the surface to be the reference insolation (1000 W/m2) and the ambient temperature to be the reference temperature (298 K).
Under these conditions I expected to obtain that the module power output was 17x5.9 = 100.3 W, but I have only got 80.2 W.
Which is the reason for this difference?
How can I simulate that the module is operating at its maximum point?
Thanks in advance,
Regards.
David.

Michele,
There are two tools available for determining the quantity of coupling airflow. One is Type97 (or Type98) (both of which are links between TRNSYS and a freely available software tool called CONTAM). The other is a commercially available TRNSYS add-on called TRNFlow. The idea behind both is that the Trnsys building thermal model (Type56) provides zone temperatures to the airflow model (CONTAM or TRNFlow). The airflow model takes those temperatures (as well as ambient conditions and a certain amount of building geometry with which the thermal model is not usually concerned) and computes the corresponding interzonal air flows. These are passed back to Type56, which recomputes zonal temperatures. Iteration continues until both the thermal and airflow models agree.
kind regards,
David

Hi, I m designing a church with different thermal zones and the common surfaces are set to virtual surface. I activated the coupling . What would be the ideal coupling air flow?
