Toplotno dimenzioniranje in konstrukcijska zasnova prenosnega skoraj ničenergijskega rastlinjaka brez zunanje oskrbe z vodo

Hafner, Leon (author), Poredoš, Primož (mentor), Arkar, Ciril (comentor)

V nalogi smo obravnavali toplotno obnašanje prenosnega rastlinjaka s tehnologijo atmosferskega pridobivanja vode – AWH, namenjenega gojenju rastlin na sušnih in polsušnih območjih. Izdelali smo numerični model za izračun temperatur in toplotnih tokov ter 3D-model v programu SolidWorks. Rezultati so pokazali, da na temperature vplivajo predvsem dimenzije rastlinjaka, sončno sevanje in senčenje zemlje. Povečanje prezračevanja je najvišjo temperaturo zmanjšalo le za 0,37K. Z računalniškim 3D modelom smo določili končno geometrijo in razporeditev glavnih komponent rastlinjaka.

• Title: Thermal Design and Structural Development of a Portable Nearly Zero-Energy Greenhouse without External Water Supply

Abstract

This thesis examines the thermal behaviour of a portable atmospheric water harvesting (AWH) greenhouse intended for growing plants in dry and semi-dry regions. A numerical model was developed to calculate temperatures and heat flows, along with a structural model in SolidWorks. The results showed that temperatures are mainly affected by greenhouse dimensions, solar radiation, and soil shading. Increasing ventilation reduced the maximum temperature by only \SI{0.37}{\kelvin}. The CAD model was used to define the final geometry and arrangement of the greenhouse’s main components.
