[TRNSYS-users] Basic help about Type16i

[KEILHOLZ Werner]

Is it worth noting in this context that in Trnsys18 we now use combined data reader + solar radiation processor types (type 15, type 99 for user-defined data ...) that have a potential of avoiding this kind of problem altogether ? (they did not exist in Trnsys16 if I remember it correctly and this kind of problem was one of the motivations for creating them back in the last century)

Nicolas,

 To follow on what Jeff said, make sure that the values that are in your data file are totals for each hour (not instantaneous values measured at some point in the hour) and also make sure that your Type9 is NOT interpolating the data; Type9 does a linear interpolation while Type16 does an interpolation that is appropriate for solar radiation profiles. If Type9 is set to interpolate then a double interpolation is being done.

best,

 David

Hello,



I got no answer so far.

I check other models and I guess know that it's not a mistake of mine but something inherent to Type16.

Is there any improvement available (in TRNSYS 17 or 18)?



Thanks



Kind regards,

Subject: [TRNSYS-users] Basic help about Type16i



Hello everyone,



I've a problem when using Type 16i with TRNSYS17.



I read hourly data, but I want to perform 10 minutes calculations. When I calculate the solar radiation, Type16i gives me those strange zig-zag curves (pink and orange). I really don't know what I'm doing wrong. Can you help me?



Thanks in advance,



Kind regards,



Nicolas, from Belgium
