However, I can't seem to find Type 604
in the TESS Hydronics library. Instead, I see that Type 604 is listed among
the individual TESS components. Do you think it would be possible to use
Type 31 or Type 709 (TESS Hydronics) instead, connecting the "environment
losses" output as GAIN in Type 56, or is this a bad idea since I can
not separate conective and radiative gains?
<I need to model heating pipes commonly found in
greenhouses. The pipes are in loops located 15 cm above the floor, 1 m above the floor, along
the walls and somewhat below the ceiling. Hot water flows in the pipes and heats up the greenhouse. I use Type 56 to model the greenhouse, but have not yet succeded in finding a model for the heating pipes. Does anyone know an appropriate model for the heating pipes and how to use it in combination with Type 56? >
We use the Type 604 model (TESS Hydronics) which accounts for the convective and radiative heat transfer to the zone. Then simply set
up a new "gain" inside of Type 56 and set the radiative and convective
gains as inputs to Type 56. Then make the connections from Type 56 to the
pipe (zone temperature and effective surface temperature) and from the pipe
to Type 56 (radiative heat transfer and convective heat transfer).
