Re: [TRNSYS-users] creating meteonorm/using exact solar data

["Matt Duffy" <duffy@tess-inc.com>]

Dear Muttakin,

In order to use in TRNSYS, your data collection software needs to gather the total radiaiton. If the data collection software does not do that, you will likely have to write a simple program or manipulate it in Excel so it sums the data for the hour period for an hourly data file. Thus, the units would be W.h/m^2 as in the TMY2 and Meteonorm files for radiation. Then once you have that hourly data file, you will use Type9 to read it into TRNSYS (and convert units) and Type16 to process the radiation. Please refer to the example in the ".\Examples\Weather Data..." directory for guidance for setting the parameters of those components. Also make sure to NOT interpolate the radiation data in Type9 as the radiation processor does that. Type16 will output the radiation average values over the simulation timestep (not the data timestep) in order to use in your simulation as Type15 does.

Best regards,!

Subject: [TRNSYS-users] creating meteonorm/using exact solar data

Hi all,

I will try to make my question as simple as possible. I have a solar thermal system and I want to simulate that using trnsys. I made the simulation using type 15-6 meteonorm for my location. But to verify the simulation I need to use the exact solar radiation data of particular dates. I have a pyranometer installed, so I have the solar radiation data in W/sqm in *.txt or ! *.xls format. I want to use this data in trnsys to run the simulation. Please suggest me the possible solutions.

Regards,
Muttakin.
