[TRNSYS-users] Description of active layer values

Dear All,

As I am trying to perform simulations of the single room with ceiling
heating system, I would have some questions regarding the values definition
of the Active Layer window, presented below.

1. What is the meaning of the "*gain*" value?

2. When I am performing the simulation in TRSYS with different "*min.
desired inlet mass flowrate*" values, I got the same results (for example,
I changed the specific value from 20 to 50 and the room temperature curve
remains the same). Thus, what does the value represent? How is it connected
with "*inlet mass flow rate*" value?

3. In the active layer definition, I put the* inlet temperature* and *mass
flow rate* numbers. However, how is it possible to obtain the *outlet
temperature* of the heating system?

4. How can I measure the value of the surface temperature of the ceiling?

5. What does the *Qsens* represent in more details?

If there is a document where I could get more information of the
aforementioned values description, please let me know.

I would like to thank you in advance for your help.

Kind regards,
Lukasz Watly
