Re: [TRNSYS-users] capacitance- TRNBUILD-TRNSYS 17

Ilyas,

 I generally use a value that is 5 times the default. As Toni correctly pointed out the default accounts only for the thermal capacitance of the air contained in the thermal zone.

kind regards,

 David

Hello.

I have a question about the capacitance of TRNSYS zones.

I see in the TRNBUILD that the value by default to calculate the capacitance (volume of the pieces * 1.2). it's logic ?. thank you.
