[TRNSYS-users] capacitance thermique

[David BRADLEY via TRNSYS-users]

Ilyas,

  If you are talking about Type56 then the thermal capacitance of the 
walls are already taken into account in the wall model by your 
definition of the wall materials. The thermal capacitance that you're 
being asked to specify is the thermal capacitance of everything else in 
the zone (furnishings, air, contents). A typical value would be about 
volume*1.2*5 (ie. five times the thermal capacitance of the air 
contained in the zone).

kind regards,

  David
