[EnergyPlus_Support] relation between "Air balance air energy storage" and air temperature variation



Hi,

Due to the definition of "air balance air energy storage rate", it should be a direct link between this output and the variation of mean air temperature of a zone. 

Cv dT/dt = sum(thermal flux) = air balance air energy storage rate (W)

No ? 

In practise, it works around 50% of the time. 

"air balance air energy storage rate (W)" / ( Temp(step)-Temp(step-1) ) 
is often a constant (131 in my case) but not always.

Sometimes it's between 200 and 250, and I really don't understand which factors could entail this...

There is mostly something I misundestood...

Somebody have an idea ?

Thanks a lot
