Re: [TRNSYS-users] Artificial lighting in Type 56, convective part




David,

Thanks for your help. Can I use the "scale" field to adjust the total heat gain? For example, if I want 200 W/m2, can I choose 100 W/m2 from the total heat gain pull-down menu and set the scale to 2?

Thanks,
Knut Erik

Knut Erik,
 The entire power that you specify goes to heating the space. The split indicates that the energy gain from incandescent bulb is 10% convective and 90% radiative.

Hi all,


A short (and possibly stupid) question: Under Artificial lighting Gains in Type 56, does the "convective part" mean the percentage of lamp power converted to heat? This fits with a test simulation I ran, but not wth incandescent lamp having only 10 % convective part as it says in the pull-down menu.


Thanks,

Knut Erik
