Dear trnsys users,
Hello, I'm a user of TRNSYS 16.
I have to simulation about radiant floor cooling using active layer.
For simulation, first I modeled one zone with 6 walls. And, boundary condition of all walls set to same outside dry bulb temperature (no solar radiation).
Zone's initial conditons were set to 30C, 65%(experiment values).
For example, supply water temperature is 40C, flowrate is 150kg/hr.
After simulation initial temperature of floor construction with active layer was different other walls.
results=>
*Floor constuction: initial inside wall temp.=25C, initial outside wall temp.=20C
*Ceiling, other vertical walls: initial inside wall temp.=30C, initial outside wall temp.=30C
My Question!!!
Why is not the floor construction's inside temperaure 30C like other walls?
Why always same initial temperature(inside wall temp.=25C, outside wall temp.=20C) in floor construction with active layer?
Why not change?
Someone who knows something about this, please help..
