AGRIMEC greenhouses are designed and built using the semicircle arc as shape of the vault.
For several years AGRIMEC tested and kept till now this configuration on the base of the following benefits:
- wind effect: lift (vertical lifting) and less transversal push
- less covering surface, less heat dispersion
- more useful height (H) at same maximum height
- best film inflating
- less film deterioration
- good unloading of snow at same time
Agrimec advises to build the greenhouse “when admitted” using a square layout, the layout that – at volume equality – reduces to the minimum the dispersant surfaces.
Studies on greenhouses (T. Foulard and H. Fatnassi, INRA-Unité URIH (France), “New models help optimise greenhouse design”, in FlowerTECH 2006, vol. 9/n.6) have verified the importance of the height of a greenhouse and, also in this case, AGRIMEC models satisfy the required parameters at best.
These studies have indeed shown that the internal air temperature decreases when the height increases up to 4 meters and that after such quote the improvements become not very significant as the following diagram shows.
