Re: [TRNSYS-users] heat capacitance of furnishings ect.

[David BRADLEY <d.bradley@tess-inc.com>]

Karol,
The general rule of thumb that I use is 5 times the default (which accounts only for the thermal capacitance of the air). The formula ends up being ZoneVolume*1.2*1.007*5 (1.2 is the density of air, 1.007 is the specific heat)
Best,
 David

Dear All,

 

I model block of flats in TRNSYS. One Dwelling is one zone.

I am wondering how can I estimate heat capacitance of zones. I take into account partition walls and air, but what about furniture and other equipment?

 

Do you have some idea/experience? maybe some constant coefficient should be applied by me?

 

Regards,

Karol
