Re: [TRNSYS-users] which radiation processor for type56



Xavier,
The problem could come from any number of sources. I would suggest that you plot out (using Type65) the amount of solar radiation that you are sending to Type56 and make sure that it looks reasonable for the location that you are studying. If it does, then you can start to look at other possible sources of the high cooling load (high internal gains). Very low zone capacitance may also contribute to loads that spike very rapidly.

As a side note, I would recommend NOT using any of the Type16 radiation smoothing modes. The smoothing algorithms implemented in TRNSYS 15 were fine for certain weather files and caused major problems with others. The smoothing algorithms were removed from TRNSYS with the release of version 16.
Kind regards,
 david

Hi,
I solved the error p[reviously asked upon.
(some confusion in the input of some new data: I hope prebid in trnsys 16
has a better interface)

I am getting unsure about which weather data to use and which Radiaton
processor to use.

I have created a weather file from meteonorm and used so far
type 16  #j#, but trying to track an error, i found I could not get some
data into it (next step...)
so I used type 16 #i# with no smoothing,

I get now a cooling load approx. multiplyed by 8. I cannot understand the
relation
I wonder if it could come from this change of radiation processor or if I
managed to introduce another error.

Any hint?

thanks
XAvier
