[TRNSYS-users] Ssurface Temperature

[Elise BERNARD]

Hi Marion,

Thanks for your answer but it's not the problem here.
The floor is between two zones with the same use.

Hi Elise,

I assume that your floor is defined as a boundary surface.
Check the defined boundary temperature of the floor. IT might be set to 0.

Betreff: [TRNSYS-users] Ssurface Temperature

Hi,

I use TRNSYS to model an office building (new construction, good insulation) and check the comfort inside.
I would like to verify the surface temperature of the floor of each zone. So I use the build surface outputs 17 TSI and 18 TSO.
The set temperatures are 20°C during the day and 16°C during the night.
The surface temperature of the floor seems to be very low sometimes : 2°C or 3°C below the set temperature.
I already checked the ventilation, infiltration, heat temperature, temperature of zones nearby.

Did you already observe this kind of results ? Do you know why ?

Thanks

Elise Bernard
