Definitions
- the invention relates to an arrangement of a closed greenhouse with optimized temperature control.
- the invention also covers an arrangement of a closed multi-module greenhouse.
- the panel area is limited to the available area of walls on the wall opposite to the extraction and the ratio cannot be increased.
- the aim of the present invention is to provide an architecture which aims to increase the surface of the panels, their distribution and the extraction rate in order to significantly reduce the temperature.
- the ratio of renewal rate / evaporation surfaces is increased.
- the primary goal is to find additional evaporation surfaces and additional surfaces to accommodate additional air extractors, while maintaining the useful cultivation surface and the potential for light penetration into the greenhouse.
- the aim is also to operate on solar energy since the temperature to be regulated is even more so when the sun is active.
- the closed greenhouse according to the present invention is a total barrier to insect penetrations while retaining the maximum transmission of photosynthetic radiation for conservation of the organoleptic qualities of cultivated varieties.
- the present invention is characterized by an arrangement of a closed greenhouse with optimized temperature control, comprising at least one module, comprising a framework and a peripheral film so as to constitute a closed enclosure, comprising a front wall, a wall rear and two left and right side walls as well as a roof with a ridge, as well as at least one access opening with an airlock, at least one evaporating water diffusion panel, a water supply circuit and at least one interior air extractor, this at least one interior air extractor is arranged in the immediate vicinity of the roof ridge so as to overcome the aforementioned drawbacks.
- This at least one interior air extractor is more particularly arranged vertically and even more particularly on the roof sections, unhooked, vertical.
- the diffusion panels are preferably arranged at ground level and on at least one side wall.
- FIG. 1 shows a schematic perspective view of a module of a closed greenhouse arranged according to the present invention
- FIG. 2 shows a schematic side elevational view of the same module, from the side of the inner face of the side wall, showing the interior arrangement
- FIG. B is a view of an evaporating water diffusion panel
- FIG. 4 shows a view of a closed greenhouse with several successive modules in the same volume.
- FIG. 1 The arrangement of a closed greenhouse 10 according to the present invention is illustrated in Figure 1.
- This closed greenhouse 10 in known manner comprises a frame wrapped with a film 12 adapted to close the volume defined by the frame 14 , this in a well-known manner.
- the fastenings of the film to the framework, the architectural methods of the framework, the bracing and other mechanical components are of no interest to the invention, the latter finding application in all types of construction. closed greenhouses.
- the closed greenhouse 10 is therefore an entirely closed enclosure and for simplicity, a single module 10-1 is provided in this figure so as to allow an easy and clear description.
- the closed greenhouse module 10-1 comprises a front wall 16, a rear wall 18, a left side wall 20 and a right side wall 22 as well as a roof 24.
- the front wall 16 has no particularity except generally to provide an opening equipped with a penetration lock, not shown, in order to allow the entry and exit of personnel, machines and plant material .
- This front wall 16 is made from the same film as the other parts of the greenhouse.
- the rear wall 18 is generally identical to the front wall 16 except for equipment such as the entry lock which may be present or absent.
- the longitudinal direction is considered along the axis XX '.
- the right and left side walls consist of the film and do not have any constructive features. These right and left side walls may also include openings instead of or in addition to the openings made in the front and rear walls. These right and left side walls ensure the continuity of the seal. At least one of the left and right side walls is equipped with evaporating diffusion panels 26. These evaporating diffusion panels 26 are positioned vertically close to the ground, that is to say at the level of the cultivation area. In the embodiment presented, the left 20 and right 22 walls are equipped with such evaporating diffusion panels 26. These evaporating diffusion panels 26 will be detailed later. These evaporating diffusion panels 26 constitute a continuous or discontinuous surface in the immediate vicinity of the wall in question. These evaporating diffusion panels 26 are generally placed inside the volume of the film so as to be fully integrated. Certain evaporating diffusion panels 26 could also constitute a part of the closed enclosure instead of the film, the film then being connected in a sealed manner to said panels.
- the closed greenhouse 10 comprises external air intakes 28, passing through the film in a sealed manner and opening into the closed enclosure of the closed greenhouse.
- these exterior air intakes 28 are connected to the evaporating diffusion panels 26; by conduits 30 in the particular and non-limiting embodiment presented.
- the supply of outside air is carried out di- directly by suction through said panels.
- the outside air intakes 28 are protected from any intrusion by pests and parasites by an anti-intrusion net with a suitable mesh, for example with a mesh of 250 ⁇ m to 730 ⁇ m.
- the closed greenhouse 10 is also equipped with water supply means 32 of the evaporating diffusion panels 26.
- This water can always be renewed or partly recycled. It is in a known manner, distributed in the upper part of each evaporating diffusion panel 26, so as to cause a gravity surface flow over the entire surface of each evaporating diffusion panel 26.
- the roof 24 is made in a manner also known from the same film or a film of a different nature depending on the mechanical strength requirements or specific radiation transmission needs if necessary, the sealed connection being made with the 4 other side walls to form the closed enclosure.
- the roof forms of closed greenhouses are generally vaulted or pointed, symmetrical to the side walls with a ridge.
- the roof 24 comprises at least one interior air extractor 34, motorized, in this case a line of interior air extractors 34, motorized. This at least one interior air extractor 34 is placed in the immediate vicinity of the ridge.
- the roof 24 of the closed greenhouse arranged according to the present invention comprises at least one roof pan 24-1, unhooked, vertical, in discontinuity of the vault or ogive shape of the roof, so as to position the extractors vertically.
- These interior air extractors 34 are integrated in the film in a sealed manner and carry, at least on one of the faces, an anti-intrusion net of pests and parasites such as the exterior air inlets 28.
- the air extractors interior 34 thus arranged, very strongly limit the impact on the ground as regards the shadow cast, especially if the general orientation of the greenhouse and the position of the stall on the roof are spared in a suitable manner with respect to the travel of the Sun.
- an air extractor line 34 oriented along the axis XX ' is provided. Also advantageously to promote circulation that is laminar rather than turbulent, with better temperature homogeneity in the closed greenhouse 10, the line of interior air extractors 34 is parallel to the line of evaporating diffusion panels 26.
- the evaporating diffusion panels 26 are shown in Figure 3 specifically and comprise cores 36 of porous material, for example cellulose fibers, the main plane of which is oriented vertically, in operation. These cores 36 are kept in a frame 38, so as to constitute a monolithic element, manipulable and intended to be fixed on a suitable support connected to the framework of the closed greenhouse.
- the cores 36 may have a surface shaped with corrugations in order to present an increased diffusion surface.
- each exterior air duct 30 of the exterior air inlets 28, opens into the core 36 of an evaporating diffusion panel 26 so that the air circulates through said core 36.
- Each evaporating panel diffusion 26 comprises in the upper part a ramp 40 for delivering water from the water supply means in the form of nozzles for example, preferably oriented upwards to avoid clogging by any lime present.
- water recovery means 42 are provided in the form of a gutter for example. These water recovery means are integrated into the water supply means 32 for possible recycling.
- the connection to the panels is provided. photovoltaic 44.
- the advantage is that the electrical energy requirements of the closed greenhouse arranged according to the present invention and the production of electrical energy by photovoltaic panels follow the same daily curve, which dispenses with significant storage means, only one buffer storage is necessary as in any photovoltaic installation. Connection to the power supply network, when possible, is generally provided in the event of a breakdown or specific needs.
- the closed greenhouse according to the present invention is provided with computer control means, programmable 46, in order to manage the various parameters of the various organs, such as the water supply, the extracted air flow, this according to the parameters of the outside air and the parameters sought in the greenhouse.
- the operation of the closed greenhouse arranged according to the present invention is now described.
- the ground area covered by the closed greenhouse according to the present invention is fully available for cultivation, with the exception of the slices of the evaporating diffusion panels 26, which is extremely limited.
- the water supply means 32 are put into service and the ramps 40 deliver water to the upper part of the diffusing evaporating panels 26. This water flows by gravity in the panels, through the cellulose fibers in the occurrence.
- the interior air extractors 34 are put into operation and create a vacuum in the closed greenhouse. Outside air is therefore introduced into the closed greenhouse by the air inlets 28 and in particular by the ducts 30. The air circulation leads this outside air through the evaporating diffusion panels 26 and due to the depression.
- this air is extracted from the panels to diffuse into the general volume of the closed greenhouse.
- the air becomes charged with humidity and when it is extracted from the evaporating diffusion panel, evaporation occurs and therefore a decrease in the air temperature by the adiabetic effect linked to this. liquid / vapor phase change, a transformation which is endothermic.
- the air circulates in the volume of the greenhouse giving it a given humidity level before being extracted from the interior volume of the greenhouse by the extractors.
- the air flows from the evaporating diffusion panels 26 at ground level to the interior air extractors 34 so that there is a relatively laminar flow of air from the bottom to the top of one hand and one wall. lateral to the other on the other hand, which contributes very strongly to a homogenization of the temperature as of the hygrometric rate.
- the greenhouses can include several modules 10-1 to 10-n twinned.
- the roof 24 covers the entire production area and comprises as many vertical sections as there are modules in the embodiment shown
- the closed greenhouse 10 still only comprises a front wall, a rear wall and two side walls. right and left, the intermediate partitions having been removed.
- the additions such as the entrances with airlock are arranged as needed on the front and rear walls, the side walls being provided with lines of evaporating diffusion panels 26.
- evaporating diffusion panels 26 are arranged between the modules, according to lines, with interruptions to generate dirty cross aisles between the modules, without having to go to the ends.
- each module 10-1 to 10-n comprises two lines of evaporating diffusion panels and a line of interior air extractors. This makes it possible to even more homogenize the diffusion in the volume of the closed greenhouse with two circulations which are grouped together near the extractors.
