[TRNSYS-users] slabcooling (minimum desired inlet massflow rate)

[Matt Duffy]

Dear Teodor Spita,

This minimum flow rate in an active layer is somewhat foreign and
confusing to me, but I noticed this in the text.

>From page 30 of the Volume 6 TRNBuild Manual...

"According to the equations given in the manual a specific minimum
massflow rate is necessary to assure that a linearization of the
exponential curve between inlet and outlet temperature is possible. In
most common cases the specific massflow rate has to be greater then 13
kg/hm² (the exact value is calculated for each active Layer)."

I hope this helps.

Regards,

Matt Duffy

Hellow,

Does someone know what the "minimum desired inlet mass flowrate" means in an
active layer. I don't understand the meaning of this input. I just want to
create
slabcooling with an active layer and there are 3 things to input: 1. The
inlet flow temperature, 2. the mass flow rate and 3. the minimum desired
inlet mass flowrate.
I don't understand the meaning of this third input.

thanks
Teodor Spita
