Re: [TRNSYS-users] greenhouse component

Stamatia,
 If you are dealing with a greenhouse that has glass walls and roof
then you can pretty easily employ Type56. You can use on of the slab on
grade models in the TESS Ground Coupling library to get a better estimate
of the energy transfer between the greenhouse floor and the ground. If
you are looking at a greenhouse that has a very low resistance skin
(plastic sheeting) then you might look at the following (sent to me by
Michael KUMMERT when I asked this same question):

You may find some information in a paper that was recently presented at
the "Systems Simulation in Buildings" conference:
 
E. Mashonjowa, J. G.  Pieters, J. R. Milford1, F. Ronsse, S. Denys,
R. Lemeur - THE USE OF A TRNSYS BASED DYNAMIC GREENHOUSE CLIMATE 
MODEL TO SIMULATE THE MICROCLIMATE IN A TYPICAL ZIMBABWEAN GREENHOUSE ­
in proc. of the 7th International Conference on System Simulation in
Buildings 
(SSB), Liège, Belgium, December 11-13.
 
The authors use the so-called "Gembloux Dynamic Greenhouse Climate
Model (GDGCM)" that was originally written for TRNSYS 13 and was
adapted and validated in TRNSYS 16. Another reference is:
 
Pieters J. G. and Deltour J. M. 1997. Performances of greenhouses with
the presence of condensation on cladding. J. Agric. Engng. Research. vol.
68: p. 125-137.

Cheers,
 David
