RE: self-heating

Hi TRNSYS users,

Adding some thermal mass is sometimes useful to eliminate the self-heating feature.
Remarkably, self-cooling never seems to occur ...

Best regards,

Arie.

Hi!
I have also had some problems with increasing temperatures up to several 
hundred Celcius inside type 56 (self-heating!?). It looks like if there is 
a large deck-file with a hundred different components, type 56 should be 
placed in the beginning of the deck-file, to avoid "self-heating"

I have also had self-heating, when I used type 2 (on-off controler) with 
the "new control strategy". Check that you don?t use the "new control 
strategy" if you have the on-off controler in your deck-file.

Best regards/
Tomas Persson
