Re: [TRNSYS-users] Surface Temperature

[David BRADLEY <d.bradley@tess-inc.com>]

Elise,

 There are a lot of things that could cause this behavior. If the building is sitting on the ground, the most likely problem is that the ground temperature under the building is (incorrectly) set to 0C. In any case I cannot think of a physical reason why this would happen so my guess is that there is an incorrect assumption or connection. If you aren't able to find the cause then perhaps your Trnsys distributor can assist.

kind regards,

 David

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
